Positive Condensate Drainage from Heat Transfer Equipment Under Modulating Steam Conditions
Understand how a good heating system design on paper can become a big problem once installed. Positive Condensate Drainage from Heat Transfer Equipment under Modulating Steam Conditions November 13, 2017 CNY Expo - Looked Good on Paper… Types of Heat Transfer Direct The heating medium is directly mixed (convection) with the substance being heated i.e. “Direct injection”.

DOAS Enthalpy Wheel (EW) Issues
DOAS Enthalpy Wheel (EW) Issues: 1. Is it required for DOAS? Yes for all practical purposes in the USA. Both ASHRAE Std. 90.1 and ASHRAE’s new Standard for the Design Of High Performance Green Buildings (189.1) require a 60% effective total energy recovery (TER) device for even the smallest systems in the moist USA--located primarily east of the continental divide as illustrated below: 2. Life and durability. The following link provides useful information, particularly concerning the life expectancy. http://www.thermotech-usa.com/tech_heatwheel 3. Purge, a basic description of how it works is at the following link: http://www.thermotech-usa.com/tech_purge . The presence of the purge requires an increase in air flow beyond the desired supply air delivery requirement, increasing fan energy use. Therefore unless absolutely needed for air quality reasons (most all-air systems in commercial facilities recirculate up to 80% of the air—so what is a few percent recirculation at the EW going to hurt) purge should be avoided. 4. Seal leakage is an equally important issue. Like purge, seal leakage should be minimized for fan energy savings as well. This requires wheels with tough wear resistant and very planar faces. And the seals must be very close fitting. 5. Dirty Socks Odor Syndrome: Published references for EW occurrences are not readily available at this time. However the syndrome occurrences have only been reported where a silica gel desiccant on non-aluminum matrix substrate EW is used. There have not been reports of this syndrome problem for applications where a molecular sieve (zeolite) desiccant on an aluminum substrate EW is used. -
How to Perform Mold Inspections
~ 1 ~ HOW TO PERFORM MOLD INSPECTIONS Mold inspection is a specialized type of inspection that goes beyond the scope of a general home inspection. The purpose of this publication is to provide accurate and useful information for performing mold inspections of residential buildings. This book covers the science, properties and causes of mold, as well as the potential hazards it presents to structures and to occupants’ health. Inspectors will learn how to inspect and test for mold both before and after remediation. This text is designed to augment the student’s knowledge in preparation for InterNACHI’s online Mold Inspection Course and Exam (www.nachi.org). This manual also provides a practical reference guide for use on-site at inspections.

Question: Why use a flow-through style humidifier rather Question: How much water does this humidifier use? than a drum style humidifier? Answer: This humidifier incorporates a restrictor which Answer: This will depend on several factors including size of meters the amount of water supplied to the unit. In the home, style of furnace, and size of ducting; as well as personal average home the unit will use totally 56 US gallons (47 preference. However in order to use this model flow through Imperial gallons, 212 Litres) of water per 24 hours of you will require at least 10" wide ducting where as our drum operation. styles will fit on 8" ducting. Comment: As mentioned above 24 hours of operation refers Comment: Flow-through and rotating-drum style evaporative to humidifier operation, the 24 hours operating time may take furnace humidifiers will safely and efficiently humidify 90% of 3 days to complete. When Compared to the water consumed homes which use forced air heating. As a manufacturer of during the average shower (3 to 5 gallons per minute) the total both styles there are pro’s and con’s to be considered when amount of water consumed to humidify your home is not that choosing a type of humidifier. A drum style humidifier is much. typically 100% efficient in its use of water, meaning all the water it uses will be delivered to the air. -

How to Prepare Your Crawl Space for Installation If you decide to install your dehumidifier in a crawl space, there are a few steps you need to take prior to installation. 1. First, you will need clean out any debris that may be cluttering up the crawl space. This will make sure that there are no hidden problems such as cracks in the foundation. It will also ensure that the vapor barrier can be installed properly. In addition, cleaning out any unnecessary items will make it much easier to move around in the crawl space. Being able to move around more easily is useful for a hassle free installation, as well as for future maintenance that may need to be done. 2. After the crawl space is clear, you will need to inspect it for any potential issues so they can be fixed prior to installation. For instance, you may notice signs of pests or rodents in the crawl space. The crawl space could also show signs of structural issues, such as damaged floor joists or girders. Most importantly, you need to ensure that all signs of excess moisture are taken care of. -
