An Investigation Of Dx Cooling Coil Inherent Characteristics, Krittima Santiwattana
Durham School of Architectural Engineering and Construction: Dissertations, Thesis, and Student Research
DX cooling coil (DCC) systems have dominated light commercial and household applications in the U.S for several decades. Approximately 14.5% of energy use is consumed by space cooling in commercial buildings, whereas 87% of households are installed with air-conditioners. Improper installation, poor design, and lack of optimized control/operations incur faults in HVAC systems causing 25% to 50% energy waste in a building. These consequences are subject to inefficient equipment modelling of which is developed from: (1) insufficient understanding in equipment characteristics, (2) uncertainties in testing environment and data, and (3) access and cost limitations. Therefore, in this thesis DCC inherent …
