Date:16-12-2011 CSCEC - Mechanical 10:27:59 Does 2004 have same content with 2008, do you have SI version? CSCEC - Mechanical 10:28:56 2008 ASHRAE Handbook-HVAC Systems and Equipment in my hand is I-P version beki 10:30:18 I have 2004 SI as well as I-P version. I do not expect the content to be the same with 200 8. CSCEC - Mechanical 10:33:18 I got a note in chinese said that ASHRAE update its whole version every four years, that why I think maybe in the previous version the main content should be the same. beki 10:36:46 I have checked now, as I have two versions 4 year difference I compare 2009 with 2005...... Totally different. beki 10:37:39

beki 10:37:59

beki 10:38:24 The first is from 2009, the second is 2005 CSCEC - Mechanical 10:41:13 Not as I imagined beki 10:44:43 Actually I was also very surprised. It seems to make the references to ASHRAE more co mplicated as the year should always be mentioned. I think it would have been more wise t o update while maintaining the same indiexing. New issues to be added at the end of exisi tng ones. CSCEC - Mechanical 10:44:55

CSCEC - Mechanical 13:29:56 The Little House series is based on decades-old memories of Laura Ingalls Wilder's child hood in the Midwest region of the United States during the late 19th century. The best- known of the books is Little House on the Prairie. The books are told in the third person, with Laura Ingalls acting as the central character and protagonist, and are generally classi fied as historical fiction rather than as autobiography, although several of the later books are almost purely autobiographical. Wilder's daughter, author and political theorist Rose Wilder Lane, assisted her mother with the editing of the works. The depth of her involve ment, and the extent of her influence on the theme and content of the books, has been the subject of some debate in recent years, but almost all Wilder scholars and her biographers consider that the writing of the books was a tense but ultimately effective continuing coll aboration between mother and daughter — Wilder writing the books, Lane editing them.

CSCEC - Mechanical 13:00:24 beki 12:59:44 All OK? CSCEC - Mechanical 13:02:04 Yes, I am prepareing the letter to GMF, made a slight modification on item 2 beki 13:01:51 Good; Are also preparing an 'off the record message for Raymond? CSCEC - Mechanical 13:03:49 yes, Mr. BAI will arrange the meeting time beki 13:06:28 I think that one strong point could be made out of the fact that the cooling capacity of 509 kW in the so called 'executive summary' can easily be proven incorrect for 31.5 @ 81% R H by someone who has access to the psychrometric chart CSCEC - Mechanical 13:09:10 I agree. I have a questine about item 5‘If with an ambient temperature (read ON-COIL co ndition) of around 17 Degr. C the sensible cooling load is calculated as 320 kW, then we really wonder how you will get the 2.1 DegrC below zero necessary to achieve this with a n airflow of 13.53 m3/s"

beki 13:10:28 If the On Coil condition is 17 Degrees (outdoor temperature) and the applied capacity is 3 20 kW, then the air should comout of the coil at this low temperature. CSCEC - Mechanical 13:13:53 he must argure it is the internal building load, the building load = plant load, there is no c oil load in his report beki 13:14:48 That is why I tell him not to answer this... If he says building load..... then he should expl ain where the high latent load is coming from at peak load,this should then represent ...... number of people beki 13:17:05 8000 people (at 70W latent) will give a latent building load of 586 kW beki 13:17:56

CSCEC - Mechanical 13:24:15 I think item 5 can be argued.in case 1245people in the area,1245x120=149400w lighting 20x5000=100000w equipment 5x5000=25000w,together will be 274kw CSCEC - Mechanical 13:25:19 my point is it is possible figure for internal load beki 13:24:59 No, The point is that the load CANNOT represent building load. Because if it is building load than the Latent Load can be proven wrong. beki 13:27:11 For the calculation to be correct, the whole of the table should make sense. It can be show n that the tabel as a whole is wrong. CSCEC - Mechanical 13:33:14 I think it is more clear to point out the latent load is impossible as you analysed than to ar gue the plant load should be coil load should not equal to building load . I will make a mo dification,and send to you to check if you are not tooo tired beki 13:33:12

You keep me always pleasantly fully awake beki 13:49:24

16:02:56 Success to send file "CHILLER_SEQUENCE_r3.zip"(36.00KB). beki 15:08:45 Dear Mr. Bai,

Following the issued variation for new lounges on level 2, CSCEC had requested a comfo rt analysis using CFD calculation method in order to see if the proposed method of air co nditioning would give satisfactory results. The issued variation was based on the use of displacement ventilation with 100% fresh ai r.

Because of the climatic conditions in Mauritius the air that will be supplied in this manne r to the areas will have a high humidity content. This will result in having quite high Relative Humidity, which exceeds the recommended values for comfort.

The results of the CFD calculation show an expected range of Relative Humidity from 62 to 82%

While outdoor weather condition may be quite pleasant even with high relative humidity, the conditions indoors are experienced differently. Indoors there is no ‘breeze’ and the temperature is artificially lowered without taking suff icient amount of moisture out of the air to provide a suitable ‘room condition’

As this may well lead to complaints, I think it is important that CSCEC informs the Engin eer of the predicted results of high relative humidity, so that the design consultant can jud ge whether this is in line with its design intent or not, and take the necessary measures in case the results are not acceptable.

As the CFD calculation was done as part of the works related to the issued variation, ther e is a valid reason to submit these calculations. If CSCEC does not inform the design consultant, the company must accept all responsibil ity for any future complaint.

I therefore strongly recommend you to send the CFD calculations to the Engineer.

Regards, ...... PS this has also be sent using QQmail CSCEC - Mechanical 15:47:04 I have not seen Bai this afternoon, he told me Remond would come this afternoon. beki 15:50:47 You still have time (are you counting days, hours or minutes?)

CSCEC - Mechanical 16:42:22 in secondary circuit do we need flow switch or flow sensor? CSCEC - Mechanical 16:42:38 CSCEC - Mechanical 16:42:51

beki 16:49:16 1. There is no need for a flow switch. 2. A flow sensor can be used to measure the cooling capacity if also the supply and return temperatures are known. 3. The supply temperatature is common and can be measured as indicated on the chiller p lant schematic that I sent. 4. The flow can be measured with an expensive MAGFLOW unit, or witha relative cheap PADDLE WHEEL device. If there is no specific spec for it then I should go for the wheel. beki 16:50:15

CSCEC - Mechanical 08:13:40 [Auto reply]您好，我现在有事不在，一会再和您联系。 CSCEC - Mechanical 08:34:45 beki 08:34:51 http://www.youtube.com/watch?v=34ysz8q5lUo&feature=youtu.be beki 08:35:08 Your video will be live at:http://youtu.be/34ysz8q5lUo CSCEC - Mechanical 08:35:45 Just talked with Ramond beki 08:35:45 Any success? CSCEC - Mechanical 08:38:18 He insisted what GMF done is right, they can selection AHU01 within 509kw, in his logi c CSCEC made trouble with GMF is because of personal issue.He want to submit his pro posal to LBG,and insisted to go to arbitration beki 08:38:29 Was he alone? CSCEC - Mechanical 08:40:26 Yes beki 08:40:57 What you think, shall I write him a note? He is going to be hurt if he insists CSCEC - Mechanical 08:42:25 I do not think he will believe you beki 08:43:25 I could try not to make it a matter of believing. after all, do you believe that 1+1=2 or do you know that? CSCEC - Mechanical 08:45:24 It seems he has to fight for his company and his pride no matter how silly it is CSCEC - Mechanical 08:46:42 And I think Safdar make his situation even worse beki 08:46:26 Well maybe today I will draft something simple, and let you see it to make it really simpl e, and maybe you could send him then an off the record message. beki 08:47:46 Did you try : Your video will be live at:http://youtu.be/34ysz8q5lUo CSCEC - Mechanical 08:48:27 Not yet CSCEC - Mechanical 08:49:33

Thank you CSCEC - Mechanical 09:59:18 Can you find reference from Ashrae about condensate pipe sizing? CSCEC - Mechanical 10:00:13 Or reference from other standards beki 10:00:06 Tell me for what equipment you wish to have this; for AHUs and FCUs? CSCEC - Mechanical 10:01:24 AHU and FCU beki 10:02:11 OK, I will check if there are any reference, but have in mind that this can be considered a s normal drainage. So what you need at first is the amount of expected condensate that wi ll flow out of the units. beki 10:03:06 That you calculate with the flow-rate of air in kg/s and the reduction in moisture content given as g/kg. beki 10:16:49 About condensate drainage there are no specific regulations related to the sizing in Ashra e. what you can find is topics related to condensate from steam installations, but that is no t applicable, the other reference just mentiones an issue related to coils that have been ice d up, and that you must take care that the condensate (when it melts) can flow freely awa y. beki 10:16:59 Condensate Drains. When coils defrost, condensate that has formed as ice or frost on the coils melts. This new condensate collects in a pan beneath the coil and flows into collection drains outside of the freezer space. Because the space is cold, condensate pans are connected to the hot-gas defrost system or otherwise heated to prevent ice formation. Likewise, all condensate drain lines must be wrapped in heat-tracing tape and trapped outside of the refrigerated space to ensure that condensate can drain unrestricted. beki 10:18:38 Now I will see in the drainage sections that are part of the plumbing (not HVAC, -> not ASHRAE) beki 10:26:47 So back to ASHRAE: beki 10:27:14 Table 21 Vented Dry Condensate Return for Gravity Flow Based on Manning Equation

CSCEC - Mechanical 10:28:37 where is it？ beki 10:28:05

beki 10:28:32 2009 ASHRAE Handbook—Fundamentals (SI) CSCEC - Mechanical 10:30:22 chapter？ beki 10:30:19

beki 10:30:52 The manning equation; Chapter 22 beki 10:31:29 Can you find it or you want more? CSCEC - Mechanical 10:32:27 I found it beki 10:31:59 Happy? CSCEC - Mechanical 10:33:16 Satisfied beki 10:32:35 您和我工作好

11:39:53 Success to send file "AHU01 Condensate.jpg"(28.00KB). beki 10:40:15 156 gram per second = 0.156 l per second beki 10:43:58 Usually the slope of the pipe should be in the order of 0.5 to 1.0 percent in case you have a long run be careful for the total height difference. You can continue to go vertical as in normal drains. beki 10:49:15 There are two return methods described. One that is DRY and one that is WET. The DRY one refers to a pipe that is not full with water, the WET one is a pipe full with water. (diff erent table for sizing). Safe is usually for the beginning part to use the DRY return. beki 10:49:35 Need more, or are you already 'over-satisfied' ? CSCEC - Mechanical 10:53:01 Satisfied enough beki 10:54:01

Good, I'll be waiting your next call.

Date:04-01-2012 beki 13:23:28 Going well? CSCEC - Mechanical 13:23:28 yes beki 13:24:53 Me too. CSCEC - Mechanical 13:26:09 What is the ordinary pressure differance between the air condition and non air conditione d area beki 13:28:25 That depends on the type of room. Some rooms need over pressure (lounges) and some n eed underpressure (Kichen, toilet etc.) the level of difference should not be large, only in the order of 10 Pascal. beki 13:30:54 Ther building as a whole needs over pressure so that the warm and moist air does not ente r. I would say that about 10 Pa over-pressure would do, but of course that also depends a bit on the wind. The pressure caused by the wind is in the order of 0.5 * velocity pressure = 0.5 x 0.6 * v2 Pa CSCEC - Mechanical 13:30:20

Satisfied beki 13:31:27 How to make you happy? CSCEC - Mechanical 13:31:03 I am happy beki 13:32:09

I do not think so, you will help me beki 15:51:53 I miss you too. beki 15:54:12 What do you think of the youtube video, I think that the images could show a bit longer ( now only 3 seconds) but I had to fit it with the music and I did want to use many pictures. CSCEC - Mechanical 15:53:49 excellent beki 15:55:36 I am thinking about making also one for the Cedar - pictures, would you like that? CSCEC - Mechanical 16:01:25 Do you think it is suitble I show thevidow to the people in it? beki 16:03:48 I think all those that have acted in the movie would like to see it, are you of different opin ion? CSCEC - Mechanical 16:03:14 I AGREE beki 16:05:36 But the cedar pictures are different, they are without (other) people they only show the m oments that we enjoyed. beki 16:06:36 The cedar pictures could and should be treated as art. beki 16:50:44 How are you doing? still on schedule? CSCEC - Mechanical 16:52:40 yes，later all the colleague inMEP will have dinner together CSCEC - Mechanical 16:53:09 I will leave in minutes beki 16:54:22 Late evening dinner, or will you come back?

Good morning. CSCEC - Mechanical 08:31:30 beki 08:32:20

To say hello with a new face beki 08:34:33 Good idea. Did you see youtube that I made last night? CSCEC - Mechanical 08:35:11 I have not, I will see it later beki 08:36:09 OK, take your time (it is a bit long). It is not as nice as I would have liked it to be, but the end is good! beki 08:36:53 Tomorrow we will have a day off here. Will you be working on your travel-day? CSCEC - Mechanical 08:38:00 yes, I will work,so many thing ..... beki 08:39:13 Ok , I will be probably in the house. QQ is working there. CSCEC - Mechanical 08:42:03 When I back to CHINA, you will not can my message within several days, I have to open the web conection before I can contact you.Be patient CSCEC - Mechanical 08:42:28 you will not get my message CSCEC - Mechanical 08:42:42 can===get beki 09:02:34 Good to know that, so I will just wait and (try to) be patient. You will of course also be very busy meeting your family and friends and every body els e there. I assume you are going for test to the hospital on or around 9 January. I hope you can give me some feedback after that. I will go on Friday 13th January evening to Cyprus, and will travel be back to Beirut on S unday 22nd of January. That is your new-years eve I think. During that time I shall only have my phone 00971- 504596194 with me. If any result back from the hospital during the time that I am not in Beirut, I would really appreciate it if you could send me a message by phone.

Done beki 11:04:02

CSCEC - Mechanical 14:01:20 check LETTER-000141 beki 14:01:43 ok CSCEC - Mechanical 14:01:38 GMF'S reply beki 14:09:35 What shall I say.. Challenging, or Trash ? They seem to have an inexhaustible energy to s pit rubbish.. CSCEC - Mechanical 14:10:25 Let them take this to arbitration beki 14:12:22 You will win the case. By the way, you see that the wetbulb has been reselected to 27.3 (= 72.5% RH). CSCEC - Mechanical 14:13:12 haha,they made story so casually beki 14:20:33 The poor man, he seems completely mislead. When you put 31.5 at 72.5% RH through a coil of 509 kW then the off coil cannot be less then 18.8 DegrC and the RH in the bulding cannot be less than 72.6% ( that is without people load). The max sensible cooliong is 84 kW and that should also include the fan and duct losses. beki 14:26:19 This morning I had the following idear; Why not involve Hevacomp in a comment on the submitted calculation results. According to us these results are not possible, and show tot al incoherence between each other. If Hevacomp can agree that this result cannot be corre ct then story is finished. CSCEC - Mechanical 14:27:56 Good idear. But do you think Hevacomp may deal with this? beki 14:29:43 The shall not have to take any responsibility for the results, their only task would be to ex plain to us how to interpret these results.

Date:05-01-2012 beki 14:40:29 they made story so casually, as you so well spoken say, that a new outdoor condition has been created. Although referring to ASHRAE, the Plaisance data do not list the combinati on 31.5 @ 27.3, the 27.3 wetbulb is listed in combination with a mean coinciding DryBul b of 30.0, and not 31.5 beki 16:15:34 Hi, time is passing.. are you alright? CSCEC - Mechanical 16:14:44 [Auto reply]您好，我现在有事不在，一会再和您联系。 CSCEC - Mechanical 16:51:59 I just finished a class about control sequence to my coleagues beki 16:53:22 So how is it to be teacher? CSCEC - Mechanical 16:52:55

Not bad I think CSCEC - Mechanical 16:54:23

I will pack my suitcase this evening，I will not come back. So see you tomorrow beki 16:55:59

OK , see you then (I really miss you) CSCEC - Mechanical 16:55:44

We will meet again, believe me beki 16:57:09 That will be fantastic. CSCEC - Mechanical 16:56:29

See u beki 16:57:38 Bey ...Date:06-01-2012 beki 08:01:16

beki 08:06:58 Yes that is better, Flow sensors in the supply and temperature sensors in the return. In the house now with chocolat as breakfast and and a variety of wishes CSCEC - Mechanical 08:08:03 I THINK THE TEMP SENSORS ON EVERY SECONDARY SUPPLY PIPE IS NOT N ECESSARY,BECAUSE THERE ARE TEMP SENSOR ON THE MAIN HEADER (IN THE SCHEMATIC DRAWING YOU MADE IS T2) CSCEC - Mechanical 08:08:32

beki 08:13:45 You understand well. On the diagram that I made the common supply is measured, and the common return as w ell. But for the individual returns you can measure the temperature in order to display the ene rgy consumption per circuit. This is to be done in combination with the flow sensor. However, it would be better to put also the flow sensor in the return because the temperat ure of the return is higher, and so you have less trouble with the condensation. beki 08:19:09 I just forward you on QQmail a messager received from Halton. CSCEC - Mechanical 10:03:23 questine：why you perfer to put the blowdown downstream of the inlet valve？ CSCEC - Mechanical 10:06:43 Youhave mentioned it is easy to control, can you give me more explanation? beki 10:07:21 Believe it or not, but I was just thinking about you being so busy... The blowdow valve should be anywhere after the motorised inlet valve, but - andgthat is important - at a location that can easily be reached. That means that you maybe have to make a take-off (T) from the inlet pipe (after the motorised valve) and route this pipe (not so big in dia) to a location that is accessible. beki 10:09:56 It is easy to control...... what exactly is IT ? The adjustment for the blowdown rate shoul d be done using measurements made on the concentration of dissolved solids. Or is it som ething else that you meant? CSCEC - Mechanical 10:10:07 Can it be anywhere along the circuit, or must after the inlet valve on the supply water pip e for colling tower? beki 10:12:34 It is essential that it is after the inlet valve in order for it to be very simple. If you want yo u can put it before (but in the pipe that leads to that cooling tower, not to another or com mon) and then put a solenoid valve that needs to be activated when the cooling tower inle t valve is open. beki 10:16:42 Now I am thinking about it, I may not be completely right. beki 10:16:52 (or totally wrong) CSCEC - Mechanical 10:17:12 Ypu mean the valve is in open position so when the motorise inlet valve open,it will drai n down water. CSCEC - Mechanical 10:17:31 ypu==you beki 10:20:30 Tje idea of having it after the inlet valve was to make it simple, because the flowrate of dr ained water is then automatically controlled by the number of cooling towers in operatio n and remains a percentage of the condensate flow. beki 10:22:38 If you do it anywhere else, then you need solenoid valves to control the quantity, (or may be one modulating valve that is controlled in steps depending on the number of pumps in operation) beki 10:24:25 You==Lu CSCEC - Mechanical 10:24:29

understand beki 10:33:30

.... trying to understand GMF CSCEC - Mechanical 10:43:36 haha, you will not able to do what beki 10:44:57 Who knows, maybe eventually the wall falls, but by then I may have lost my mind and th e capacity to think. beki 10:45:42 Sure I will have a headache.. CSCEC - Mechanical 10:46:16 THEY ARE NOT WORTH YOU TO DO SO beki 10:47:23 But like the muscitos in the restaurant need to be repelled, so need they. beki 10:47:46 musquitos? CSCEC - Mechanical 10:47:47 Yes I AGREE beki 10:48:43 The musquitos Must Quit Us beki 10:49:42 I will see how to get some more contact with Halton, did you see their mail? CSCEC - Mechanical 10:49:54 No, I HAVE NOT beki 10:50:40 I send a copy by QQmail to you. beki 10:51:21 By the way, as it is nealy lunch time, how long will you be staying today (your flight is w hen??) CSCEC - Mechanical 10:51:02 I JUST FINISH IT CSCEC - Mechanical 10:52:50 I am afraid I have to leave now CSCEC - Mechanical 10:53:15 I will not come this afternoon CSCEC - Mechanical 10:53:26 the flight is at 18:20 beki 10:55:06 I wish you ALL the best and I hope to hear from you soon and as you will know by now.. . I will miss you tremendously.... CSCEC - Mechanical 10:56:04

,I will get touch with you as soon as possible beki 10:56:52

CSCEC - Mechanical 10:56:54 see you Date:06-02-2012 CSCEC - Mechanical 08:50:35 beki 08:50:52 Hi CSCEC - Mechanical 08:51:02 Hi beki 08:52:10 Some people dream and talk in their sleep, some Wizards dream and send messages in th e deep of the night, then they oversleep and are later than usual ion thier work and discov er that they left both phones at home...

Date:06-02-2012 CSCEC - Mechanical 08:53:53 haha,he is not a shrewd wizard beki 08:54:38 No just an ordinary wizzard..... By the way, Have you already contacted CSCEC in Mauri tius CSCEC - Mechanical 08:58:01 I read letter 143 from GMF,they uesd a new idea RUN-AROUND COIL.I check it on we b, it is a heat exchange system, will use water to take energy from exhaust air and translat er to supply air. beki 09:00:16 Yes I have relied to that letter, you were in copy. The idea will reduce the relative humidi ty, but at the same time increase the load. I have not seen any further details. Have you read read my letter to Mr. Bai saying that GMF tries to fool them by speaking about HAL TON? CSCEC - Mechanical 09:05:50 Although it is possible to save energy, the plan need to add equipment and to redesign the exhaust air system.This is not concept design period, so no matter what kind of solution c ould solve the problem, it is impossble to change. beki 09:06:13

A dutch say: Geduld is een schone zaak, meaning: Patience CSCEC - Mechanical 09:06:09 I read you reply. CSCEC - Mechanical 09:06:39 beki 09:09:20 There is no energy saving when using a runaround coil that processes high level exhaust. The temperature difference between inlet air and exhaust air is verly little, so you cannot use it to 'pre-cool' the air. If used after the cooling coil it will reheat the air, but that is the same as increasing the fan and duct losses, it will just force the off coil temperature down , ... and I miss you too. CSCEC - Mechanical 09:10:59 Mr Bai ask me to reply the letter,I will write the letter and send it to you first.I am not sur e when I can finish it beki 09:12:42 It is now14:10 at your place, here it is just ten past eight in the morning. Do you think yo u might have if by the end of your work day, or are you already nearly to leave the office ? CSCEC - Mechanical 09:13:01 Do you have any reference about run-around coil? send it to me please beki 09:16:57 I have worded with in on one porject and I have done the comissioning of it. I will find y ou some info, but in principle it is very simple. You place a coil in the exhaust stream (' A dd the pressure drop of this coil to the fan !!!!!) , then you use a circulating pump to get t he water trhough it and guide the waterthrough anoither coil that is addionally place near or in the airhancler (Add the pressure drop to the total static pressure !!!!) . beki 09:18:24 Have you seen the details of what they proposed, because, although the letter mentioned i t was enclosed, I did not receive any such enclosure or other details from this proposed so lution. CSCEC - Mechanical 09:19:05 I have not. CSCEC - Mechanical 09:19:38 I will ask MR bai now beki 09:19:44 If Mr. Bai asks you to comment on it, then, to be sure what they meant, beki 09:19:52 OK you got it CSCEC - Mechanical 09:42:06 GMF sent a hand copy of calculation to CSCEC,they are scanning it and will send it to m e beki 09:43:25 Ok, I will be interested to see that also... Until when will you be in 'your' office? CSCEC - Mechanical 09:43:58 within one hour beki 09:52:38 http://en.wikipedia.org/wiki/Run-around_coil http://www.robatherm.com/de/system/files/robatherm_H-KVS_eng.pdf http://www.jaschill.com/products/double-skin-ahu.aspx http://www.imofa.co.uk/heat-recovery.html

CSCEC - Mechanical 09:56:30 the exhaust air temperature is 24,what kind of water should be used? untreated water？ or dinary temperature？ beki 09:56:49 I just sent you some references that mention run-around coils. I will see if I can get hold o f ome calculation method to find the efficiency. But as I said earlier, if used for dehumidification (placed after the cooling coil) then it will increase the required cooling ca pacity for 100% fresh air airhandlers. It will need about 5 times more cooling poser than the power that is transferred from exhaust to supply air. beki 09:56:55 Hold on.... CSCEC - Mechanical 09:59:48 I will leave for ten minutes,then I will back beki 10:00:03 The water is running around between two coils. One place in the exhast air stream and th e other in or near the AHU. It is a closed circuit that needs to be filled with the same kind of water as the chilled water system. There should be an expansion vessel to absorb the v olume change of the water when the temperature varies. there should be a strainer and on e (or if redundancy is required two) circulating pump. The make-up can be directly form t he chiled water. beki 10:00:10 OK I will wait.

CSCEC - Mechanical 10:37:43 I will be back in few days. CSCEC - Mechanical 10:39:23 I will stay there for three months. beki 10:39:52 And then you go somewhere else or back to Jinan? CSCEC - Mechanical 10:40:24 Then back to Jinan first CSCEC - Mechanical 10:41:08 Do not know what will be the next beki 10:43:57 Well you have some tome to think and decide. beki 10:44:51 I hope it can be arranged that there is some work for me in Mauritius, what is your idea? CSCEC - Mechanical 10:48:56 I am not sure,when I back to working mood I will kown what should do. I am quite sure I will have plenty of questine for you beki 10:51:26 Make the questions many and un-solvable from far, so that 'they' will ask me to come. Th at I would like the best. CSCEC - Mechanical 10:56:45 I KNOW

Date:02-03-2012 CSCEC - Mechanical 10:57:22 HOW ARE YOU THESE DAYS? beki 10:58:50 I am very busy with my work, I travel a lot. But that is not all. beki 11:00:18 I am often thinking about 'mauritius'. and if you have seen my mails, you might understan d. Did you check QQmail already. CSCEC - Mechanical 11:17:12 I checked the mail quickly，in China we can not get on youtube. beki 11:20:56 I can send you by qq, the files are not so big. But I think that I also enclosed the files in th e email. Did you get: Biblos_Sea.mp4 (7MB) ? and Lu in the woods.mp4 (10MB) , these are the ones that I put also on youtybe. CSCEC - Mechanical 11:23:57 I am really in the mist recently, I think you may not understand how complicated the situ ation is. CSCEC - Mechanical 11:29:21 Try to be simple and happy. beki 11:48:39 To be in the mist... I could probably understand quite well, but with so little information f rom your side it is of course a lot of guessing. I really whished that you could share this more with me. We have been able to understand each other quite well and I think that this deserves some dialogue. And about the simple happiness. Its alright with me. I am actual ly quite happy, and feel rich with the thoughts, feelings and emotions that I can have. Sim ple is maybe not always the right word to describe me, but simple happiness, yes that co uld do often. When you will be in mauritius you can read the book that I send you. It has been so much of a joy for me to read it, that I would like you to red it too,.. the same boo k that I bought here in Beirut. CSCEC - Mechanical 11:53:45

Thank you, my professor.I know I am a quite lucky person beki 12:00:44 The book is not so much from me as a professor, athough I like that role a lot, especially with students like you, ultimate joy. I wish though that I could teach (or convince) you to be more open with me. Even in the mist, thick mist like I once experinece as a child, whe reby it was hard to see my own shoes, even under those circumstances, when beign close enough.. things can be safely shown. beki 12:01:53

CSCEC - Mechanical 12:10:41 I found it quite difficult to concentrate on something at home. I can not be quiet in my he art. beki 12:22:56 I really hope Lu that thing will clear up, I hope this for you as well as for myself. For now , probably best to just relax and wait for wisdom to come with it's answers. But for whate ver will bring this, I really want us to meet and speak, that's such a strong wish.. CSCEC - Mechanical 12:22:58 Thinking too much make me feel tired and useless, I try to be simple and happy,hope I ha ve the wisdom CSCEC - Mechanical 12:28:51 I will get down. beki 12:29:29 English please, this means you will be leaving now? CSCEC - Mechanical 12:30:23

I think I am speaking English.Do you know how much glue in my brain? beki 12:31:50 What I do know, is that you used some of that glue to stick me to you. CSCEC - Mechanical 12:34:06 See you then beki 12:35:09 Absolutely.. And don't worry about not feeling useful, your time will come , your wish is too strong .. CSCEC - Mechanical 12:37:14

CSCEC - Mechanical 09:56:44 I am checking the ticket Mr.Bai sent to me beki 09:58:26 The dates are clear? CSCEC - Mechanical 09:59:09 fridy,from Beijing to Mauritius beki 10:01:42 Wow! So you will finally pack your suitcase. Have you ever done something with the report that I made in reply to the run-around coils from GMF?

CSCEC - Mechanical 10:02:31 No, I have not finished anything, I will be when I am back beki 10:04:35 I am curious to know whatever happened with that story, and how they may have penetrat ed back into the system? did you get any information about that? CSCEC - Mechanical 10:05:53 They will not penetrate back beki 10:07:44

I am a bit shy to ask, but did you get my message about-> CSCEC - Mechanical 10:08:18

I got your message beki 10:35:15

I guess you are very busy now. Once you are back in Mauritius, you will have surely some more time and opportunities t o ask maybe even 1000000000000000 questions, which I shall of course be most willing to answer. I look forward to a bit more conversation.

CSCEC - Mechanical 10:37:14 I am sorry,I will have more time when I back to Mauritius. beki 10:38:51

Ok, I will be on line, see you then. CSCEC - Mechanical 10:38:46 beki 10:39:35

CSCEC - Mechanical 08:25:21 first day in my office, I am checking the progress. beki 08:25:44 You will be amazed CSCEC - Mechanical 08:25:42 How are you? beki 08:25:52 I am quite fine CSCEC - Mechanical 08:26:06 Why? Amazed? beki 08:27:34 I am used to the fact that coming back on a project after some time, always many things h ave unexpectedly progressed and other things that were in the make are still stuck in the mud, CSCEC - Mechanical 08:29:46 drawings of GF plan has got status2,cooling plant got status 2 beki 08:30:12 Have the airhandlers been submitted? beki 08:30:46 Have the BMS schematics been finalised and approved? CSCEC - Mechanical 08:31:49 Have not asked who in charge of BMS beki 08:34:17 I am curious about that. Also about the PMS and SCADA, as that is related to the BMS a nd mechanical (chiller) installation. CSCEC - Mechanical 08:37:45 your favorate part beki 08:38:03 Wrong beki 08:39:27 Maybe that answer was to quick, just by impulse. I do of course like the BMS part a lot. CSCEC - Mechanical 08:58:37 I am still in the mist. Although I am back I came back really hesitantly. beki 08:59:33 I understand that from your messages. beki 09:00:16 Have you committed to three month?

Date:12-03-2012 CSCEC - Mechanical 09:00:47 I tried to talk to you my feeling, but not so sure where to start and how to make it clear, b ecause I am not clear myself until now. beki 09:01:19 I would really like you to do that. beki 09:02:17 By the way, did you receive the book that I sent? CSCEC - Mechanical 09:03:49 I have not yet. It is in Mr. Bai's hand, I will ask him. beki 09:05:38 While your eyes go over the sentences you might feel better. The book I sent is the one I bought (they had only one of it). CSCEC - Mechanical 09:11:59 The past year now seems so unrealistic to me, including the high spirit for working, I do not know how I finish so many job. Without your help, most of them will never be finish ed so magnificently. I want to be sure Who I am, what kind of life I want. CSCEC - Mechanical 10:21:13 What I am trying to do is focus on my job as soon as possible, according to my experienc e thinking too much will never help, me on the contrary it used to make me depressed. beki 10:21:13 I am away now. I will contact you later. beki 10:37:33 Hi, I would like to reply, but I am cought up now in a video conference. I will not finish t his before your lunch time. So patience. pls .

12:29:56 The contact canceled sending "run around coil.psy". 0KB of 1.00KB has been received su ccessfully.

CSCEC - Mechanical 13:28:57 According to DEHUMIDIFICATION ENHANCEMENTS FOR 100 OERCENT OUTSI DE AIR AHUS (annex of GMF letter), run around coils are two coils with a small closed loop piping system. One coil is precooling coil, it locates upstream from the main coil, it absorb heat from the air. Another coil is reheating coil, it locates downstream from the m ain coil, it give back the heat get from the precooling coil to the air. The two coils functio n is quite like heat-exchanger. After the precooling coil, the main coil can treat the air int o lower temperature with the same cooling capacity, so make the air drier. Reheating coil will heat the air using the enthalpy get from the air. It is really a good idea to save reheat energy.

12:33:20 Failed to transfer "run around coil.psy". Unknown error occurred. beki 13:34:47 by mail please CSCEC - Mechanical 13:33:54 ok CSCEC - Mechanical 13:36:15 I try to make analysis but can not be sure it is right or wrong. If the run coil has the functi on what the water temperature different in the coil ? beki 13:39:10 one moment please.. beki 13:42:23 Had to have discussion with our employees.. timesharing with you. CSCEC - Mechanical 13:41:57

I have time and patience beki 13:50:29 OK, lets start. First, how many coils do you consider, and where are these located. In you r brief description I see two run-around coils and one AHU main cooling coil. One run- around coil before the AHU cooling coil and one run-around coil after the AHU cooling c oil. Do I understand correctly what you have described? CSCEC - Mechanical 13:50:00 YES beki 13:52:05 Well then, I will check now your psy chart (one moment please, checking mail now) CSCEC - Mechanical 13:51:15 I will send you GMF letter beki 13:52:29 OK CSCEC - Mechanical 14:06:25 Please read page 53 coil loop run aroud precooling, reheating CSCEC - Mechanical 14:06:49 Email is on the way.... beki 14:08:09 Ok, I will download the mail, but I have already a first assesment: CSCEC - Mechanical 14:08:00 The second mail is from GMF'S letter beki 14:10:20 The first think is to mention that you cannot save energy with the configuration that you d escribe, as you only replace the energy from before to after the coil. Saving would have b een to use the colder air that you throuw out of the building to precool the incoming air. beki 14:11:44 The second thing is that you should make the energy tranfer in the two run-around coils t he same. otherwise the universe will ex- or implode after a while. Energy in our world is always conserved. beki 14:14:11 By making these two figures the same (upstream coil takes up heat and the downstream c oil gives out the heat) then they should show the same temperature change between in an d out because the airflow rate is the same. CSCEC - Mechanical 14:14:23 Have you got the second mail? beki 14:17:08 Thus if you have the upstream coil cooling the air down from 31.5 to 27, then the downst ream coil will inctrease the temerature from 14.9 to 19.4 or somewhere there. beki 14:17:18 I will now check the second email.. beki 14:18:19 download in progress (2.5 MB) CSCEC - Mechanical 14:17:08 There has an analysis on the psychart, I can not understand beki 14:18:52 Do you understand the comments I make on the chart that you issued? CSCEC - Mechanical 14:18:32 Yes, clear.Although there are so much glue in my brain CSCEC - Mechanical 14:18:36 beki 14:20:09 I would love to have a look in your brain beki 14:21:05 I will look for a brain-glue dissolver beki 14:23:36 In fact. Brain Glue does seem to exist !! http://www.nytimes.com/1982/11/23/science/brain-s-glue-discovered.html? pagewanted=all

Date:13-03-2012 CSCEC - Mechanical 14:22:53 e air down from 31.5 to 27, then the downstream coil will inctrease the temerature from 1 4.9 to 19.4 or somewhere there.Is that mean this coil loop run around precooling and rehe ating coil can not work,or some of my setpoit are wrong? beki 14:26:21 You could have a smaller coil that transfers a bit less energy from the upstream to the do wnstream part of the coil, but that will of course also reduce the improvement of dehumid ification while keeping the AHU cooling coil working at the same rate. beki 14:30:29 Further it should be mentioned that the capacity of the cooling coil to a large extend depe nds on the ON-COIL temperature. By reducing this temperature, the coil will have a lowe r cooling capacity. CSCEC - Mechanical 14:37:06 Waiting for your comment about the analysis in the article... beki 14:38:25 I have downloaded and read the run-around coil description. They make a bit toom much advertisement for it, beki 14:42:12 The idea is to use replace the energy from before to after the coil using the run-around coi ls, and thereby alowing the AHU cooling coil to concentrate more on the dehumidification. (to speak in metaphoric way). In theory this works, but you must see the a ctual figures before deciding if this can be used. CSCEC - Mechanical 14:41:36 As you mentioned the capacity of the cooling coil to a large extend depends on the ON- COIL temperature, how to decide the difference coil capacity? CSCEC - Mechanical 14:42:29 In theory this works, but you must see the actual figures before deciding if this can be use d.----That is what I want to know beki 14:45:41 I have a program from Technisolve (makers of psychart) that can simulate coils. I think y ou have this prgram also. Check and if you want I can send it. (it is called CWC.exe). I w ill now make a check using the psy chart data you you gave me just now. CSCEC - Mechanical 14:46:36 I have that programme, I will try it. beki 14:56:55 A hint in using the CWC.exe program: After you give the data in you should press the cal culator button (icon position 4th from the left) and then the View icon, which show the re port. You can then copy the report (second option from the left on the report window, and then you can use 'Paste' in excel. So you must have an empty worksheet open, make it the active window by clicking on it and then do Ctrl+V or right-click and 'Paste' beki 14:58:38 Unfortunately I must now attend a Video Conference from 16:00 hours your time. I think it might tak an hour. I will be back after it. CSCEC - Mechanical 14:58:51 OK, I will say hello to Roshan,Safdar is on vacation CSCEC - Mechanical 16:42:44 I will be back after dinner beki 16:44:28 I am away now. I will contact you later. CSCEC - Mechanical 18:44:42 beki 18:47:16 Hi, I am nearly ready with the report beki 19:19:02 Ok, I am now going to email it beki 19:22:13 It is underway to you beki 19:22:35 check your QQ mailbox, I hope it is working beki 19:23:39 If you have any questions, in 15 min I leave the office CSCEC - Mechanical 19:22:27

I check it now, thank you, leave as you planed beki 19:28:12 Before you break your brains over the figures.... I was planning to write you something n ot-job-related, but this day was extremely busy. So I will postpone that till tomorrow, hop ing that they leave me here alone a bit more then today. Did you start reading the book? CSCEC - Mechanical 19:26:39 Yes, several pages beki 19:29:02 Do you like it? CSCEC - Mechanical 19:30:21 Can say it now. I think I need to read more, but it is somthing I have interest to know.If it is in CHINESE I will finish it soon beki 19:36:08 OK, take your time. I was quite facinated by the style he is using. Using such short senten ces but saying so much. Anyway, I am leaving now and will come back tomorrow. I find it so nice that I can talk to you again. Bey Bey CSCEC - Mechanical 19:34:12

morning.The psychart and the report do not match.Please check.

6:52:07 Failed to transfer "run around coilrrr.psy". Unknown error occurred. CSCEC - Mechanical 07:54:41 hi. I do not kown what happened, I psychart is correct. beki 07:54:50 Good morning, Please send file by mail, because it seems not possible to doit the quick w ay. I will check if I have sent the right combination. But bottom line of the story is that: If you want to dehumidify, however you do it, it comes at a price. beki 07:58:03 Additional dehumidification can be done by using part of the cooling capacity and transfo rm the 'sensible' cooling into 'latent' cooling which happens when you use run-arounnd co ils as shown, or you frce the coil to do more latent cooling by adding more heat into the s ystem (electric coil). beki 08:03:08

Do you need more explanation ? CSCEC - Mechanical 08:06:05 No, I am clear now. beki 08:06:46 Have you been asked to prepare a reply to the letter of GMF that proposes this metod? CSCEC - Mechanical 08:16:02 No, they replyed a letter but not metioned anything about this. CSCEC - Mechanical 08:17:29 I think most of the letter were written by you .You may check it on aconex CSCEC- LETTER-100231 beki 08:18:24 OK, I will check What happend with GMF and their mechanical subcontract? And.. did y ou sleep well? CSCEC - Mechanical 08:19:50 Not so well, why you ask? You can feel it? beki 08:20:05 As if you were here beki 08:27:38 I just read the letter,which is indeed my reply given to CSCEC. The next letter that I prep ared, talking about their proposal for run-around coils was only sent to you while you wer e in Jinan. This was in reply to a follow up letter from GMF, the one with encloseures. A ctually I misunderstood at that time their suggestion, as thery were speaking about saving energy. That cannot be accomplished with the confiuration that we have been talking abo unt now, but only with a system that uses the extract to precool the inlet air. beki 08:28:20 Anyway, you have been thinking so much about run-around coils. Are you going to do so mething with it? CSCEC - Mechanical 08:33:46 I will ask more information from the supplier about it. Now I try to finish niose calculatio n. beki 08:34:27 oK, if you want, let me HEAR about it. CSCEC - Mechanical 08:45:56 I will beki 08:47:05 You give me the feeling that you are more close to crying then laughing. I wish I could c heer you up. CSCEC - Mechanical 09:26:00 I am trying to be nomal. It need time. Do not worry, may be I am this kind of person, not stable. Last time, when I came back I was worse than this time. Nothing happened. beki 09:26:37

CSCEC - Mechanical 10:43:57 beki 10:43:21 Enjoy.. as much as possible.. beki 12:39:58

Just remembering... CSCEC - Mechanical 12:41:43 beki 16:14:13 beki 16:21:43

Doing fine? CSCEC - Mechanical 16:54:53 hi, I will leave not back today. beki 16:54:53 What a pitty. CSCEC - Mechanical 16:55:53

I think you can feel it beki 08:34:43 This answer is indeed one that identifies you. beki 08:35:17 Did you try to send another psy-chart? CSCEC - Mechanical 08:37:09 The one I mentioed that not match with your report? beki 08:38:08 I do not know, when I connected this morning (after the internet was back on line) I recei ved a request to accept a psy-file. But I was thinking that you had started Noise Calculati ons so I was surprised. CSCEC - Mechanical 08:39:49 No, I did not send it. beki 08:43:07 Well, then it must have been floating around, lost in space and finally landed. By the way my screen still says Non-local Sign-in although yesterday there was not such description. Maybe CSCEC changed something related to their internet connection. beki 08:43:50

CSCEC - Mechanical 08:48:21 If someday in the future, I borrow money from you through QQ, do not believe . Someti mes it happens, somebody steal the QQ number and cheat online. CSCEC - Mechanical 08:49:17

If I really need help I will call you beki 08:49:32 Ok, if someday in the future you wish to borrow money, I will ask you to come and colle ct personally beki 10:29:52 Everything according to plan? CSCEC - Mechanical 10:34:00 I had a meeting in ADPI office. beki 10:35:49 I spoke with Dominique, but not related to Mauritius. Although he mentioned that he is st ill busy with it. I did not want to get involved throught him. CSCEC - Mechanical 10:36:53 Before I came back, Mr PU has finished the first version of niose calcularion using the ex cel sheet you gave me. Roshed send it to Paris CSCEC - Mechanical 10:37:11 talk to you later... beki 10:37:52 Ok I'll be here CSCEC - Mechanical 10:50:51 ALan is here, we made a sample of jet nozzles on the pole.He is checking the sample. beki 10:51:40 Did you see it alaready? CSCEC - Mechanical 10:52:08 Yes. beki 10:53:42 You are very precise in answering... I would like to know what you thought of it, dioes it look good? CSCEC - Mechanical 10:56:16 I will send a picture to you, it is roughly manufactured because time limited, but not too b ad. CSCEC - Mechanical 10:58:20 I should leave for lunch.I am really worried about the noise calculation.Because I have no chance to change the equipment. CSCEC - Mechanical 10:58:39 Talk to you later... beki 10:59:11 There is big risk.. beki 10:59:23 Talk to you when you are back. CSCEC - Mechanical 12:19:08 Hi, I am back. beki 12:20:22 Hi I am still here CSCEC - Mechanical 12:19:53

CSCEC - Mechanical 12:27:52 The situation of noise calculation is like this, when MR PU did the calculation he found u seing the silencer we choose before can not reduce so much niose in some system. So firs t he try to change to other kind of silencer but found that pressure drop on the silencer is much higher than last one. beki 12:34:35 The situation that you describe does not show me a conclusion. beki 12:35:28 It is important to include the number of fans that are in the hall, used for the general roof extract. CSCEC - Mechanical 12:34:43 That mean we need higher pressure loss of the fan. But AHU has been orderd beki 12:36:03 Ok, do not panic beki 12:36:35 The pressure drop should be see in relation to the total pressure drop for which the fan ha s been designed beki 12:37:34 In general this was quite high as I remember beki 12:38:46 So I suggest you look at the fan curve (should be somewhere available), and add the extra silencer requirement to it. CSCEC - Mechanical 12:38:35 I know,but what we choose before is a quite simple silencer the pressure loss is not more than 15pa,if we use now silencer it will be over 100pa beki 12:40:08 This 100 Pa is still small in relation to the total pressure drop of the fan (I conveniently h ope) CSCEC - Mechanical 12:44:27 First of all, I am not sure if the calculation is right or wrong. beki 12:45:36 That is a good start CSCEC - Mechanical 12:45:11 You feel I am back? beki 12:46:22 Absolutely. beki 12:46:53 I want to be back too!! CSCEC - Mechanical 12:48:20 I want to make it clear myself only. My company can not tolerate any change or daley.No time beki 13:01:12 If you cannot afford any change, then you just have to hope for the best. As I said, for the AHUs it may not be too bad, as in general the fan total pressure is quite high. But be care ful with the extract fans !!!!!!
