Experimental Measurements of VOC and Radon in Two Romanian Classrooms
Available online at www.sciencedirect.com ScienceDirect Energy Procedia 85 (2016) 288 – 294 Sustainable Solutions for Energy and Environment, EENVIRO - YRC 2015, 18-20 November 2015, Bucharest, Romania Experimental measurements of VOC and Radon in two Romanian classrooms Marian – Andrei Istratea*, Tiberiu Catalinaa, Alexandra Cucosb, Tiberius Dicub aFaculty of Engineering for Building Services, Technical University of Civil Engineering Bucharest, 66, Pache Protopopescu Blvd. Bucharest, 021414, Romania bFaculty of Environmental Science and Engineering, Babes-Bolyai University, 30 Fântânele Street, RO-400294, Cluj-Napoca, România Abstract The present study reports by experimental measurements the levels of volatile organic compounds (VOC) and radon concentrations in two high school classrooms. The difference between the two classrooms abbreviated as S7 and S8 is the presence of a mechanical ventilation system in one of them (S8). The topic is of high importance as the indoor air quality (IAQ) can affect the health and learning performance of the pupils. VOC and RADON have a substantial weight of IAQ and a study of theirs level can help us to better understand at what levels the children are exposed daily. The two mentioned classroom have suffered recently a massive renovation. The classroom with the ventilation system was mounted with variable flow of fresh air, while the other one relies only on natural ventilation by opening the windows. In S8 several test were done for different fresh air ventilation rates. The conclusions were that in the classroom S7 there were measured high levels of VOC and radon, higher than the maximum admissible which is a serious problem. On the other hand, in the classroom S8 for all the different air rates the values were very low, thus creating a healthy and comfortable environment for the learning process. -

With Chilled Water Systems Get Precise Cooling and Control for Research and Institutional Greenhouse Growing with Chilled Water Cooling Systems
Control Cooling with Chilled Water Systems Get precise cooling and control for research and institutional greenhouse growing with chilled water cooling systems. Researchers and institutional greenhouse growers need precision, efficiency and reliability in cooling and control. Because this type of growing demands tightly controlled environments, many institutions turn to chilled water cooling. How Greenhouse Chilled Water vs. Cooling Works Evaporative Cooling Hydronics uses water as the heat-transfer medium in Many commercial greenhouses rely on evaporative cooling heating and cooling systems. Large-scale commercial and to cool air to about 10 to 20 degrees below the outside institutional buildings may include both a chilled and heated temperature. These systems lower air temperature using water loop for heating and air conditioning. While boilers mists, sprays, or wetted pads, because they introduce heat the water, chillers and cooling towers are often used water into ventilation air – increasing the relative humidity separately or together to cool the water. while lowering the air temperature. Chilled water cooling is a hydronic process that circulates While this is generally an efficient process, evaporative cooling chilled water through a loop piping system. Circulator is limited by the relative humidity of the outside air introduced pumps force the water through a heat exchanger, and a fan into the greenhouse. Under these conditions, evaporative draws warm air out and cools it as it passes over cold coils. cooling cannot provide effective space temperature control of the greenhouse under all operating conditions. Flexibility and Controlled Climate Growing The Delta T Solutions’ chilled water system uses hydronic cooling to precisely control greenhouse space temperature For flexibility, a chilled water system can be broken up into and humidity. -

HVAC Water Systems
HVAC Water Systems Dual Temperature Chilled Water Loops Summary Chiller energy can account for 10 to 20% of total cleanroom energy use. The majority of annual chilled water use goes to medium temperature chilled water requirements – 55°F for sensible cooling and 60 to 70°F for process cooling loads. When outside air temperatures are cool and humidity is low (i.e., no low-temperature water is needed for dehumidification), 100% of the chilled water is for medium temperature loop uses. Standard cleanroom chiller plant design provides chilled water at temperatures of 39 to 42°F. While this temperature is needed for dehumidification, the low setpoint imposes an efficiency penalty on the chillers. Typically, heat exchangers and/or mixing loops are used to convert the low temperature, energy intensive chilled water into warmer chilled water temperatures for sensible or process cooling loads. Chiller efficiency is a function of the chilled water supply temperature. All other things equal, higher chilled water temperatures result in improved chiller efficiency. For example, by dedicating a chiller in a dual chiller plant to provide chilled water at 55°F, 20 to 40% of chiller energy and peak power can be saved when compared to both chillers operating at 42°F. Table 1. Chiller Efficiency Chilled Water Supply Efficiency Temperature 42°F 0.49 kW/ton 60°F 0.31 kW/ton 1. The chiller efficiency reported is based on manufacturer’s simulated data of the same chiller. The water-cooled chiller was simulated running at 100% full load and had a condenser water supply temperature 70°F in both cases. -
Solar Heating and Cooling System with Absorption Chiller and Latent Heat Storage - a Research Project Summary
Available online at www.sciencedirect.com ScienceDirect Energy Procedia 48 ( 2014 ) 837 – 849 SHC 2013, International Conference on Solar Heating and Cooling for Buildings and Industry September 23-25, 2013, Freiburg, Germany Solar heating and cooling system with absorption chiller and latent heat storage - A research project summary - Martin Helm1*, Kilian Hagel1, Werner Pfeffer1, Stefan Hiebler1, Christian Schweigler1 1Bavarian Center for Applied Energy Research (ZAE Bayern), Walther-Meissner-Strasse 6,D-85748 Garching, Germany Abstract A reliable solar thermal cooling and heating system with high solar fraction and seasonal energy efficiency ratio (SEER) is preferable. By now, bulky sensible buffer tanks are used to improve the solar fraction for heating purposes. During summertime when solar heat is converted into useful cold by means of sorption chillers the waste heat dissipation to the ambient is the critical factor. If a dry cooler is installed the performance of the sorption machine suffers from high cooling water temperatures, especially on hot days. In contrast, a wet cooling tower causes expensive water treatment, formation of fog and the risk of legionella and bacterial growth. To overcome these problems a latent heat storage based on a cheap salt hydrate has been developed to support a dry cooler on hot days, whereby a constant low cooling water temperature for the sorption machine is ensured. Therefore the need of a wet cooling tower is avoided and neither make-up water nor maintenance is needed. The same storage serves as additional low temperature heat storage for heating purposes allowing optimal solar yield due to constant low storage temperatures.
