Abstract72433S03-I Current residential HVAC systems consume an unnecessary amount of energy due to equipment oversizing, incorrect refrigerant charge, and incorrect air flow. In addition, these systems do not have humidity control, which leads to discomfort or results in more energy use. This project will develop a device (HSTAT) that combines temperature and humidity control with HVAC diagnostics. The device also will reduce equipment cycling and hence energy use. In Phase I, both theoretical and experimental feasibility studies will be conducted. Variable deadband and humidity control strategies will be assessed, HVAC diagnostic methodologies will be identified, and an experimental investigation will determine feasibility. Commercial Applications and Other Benefits as described by awardee: Combining humidity control with HVAC diagnostics should provide significant energy savings and improved comfort. The technology could be applied not only for residential buildings but also for light commercial buildings.
