| Popis: |
Initial analytical and experimental investigations were conducted to establish data and design procedures prior to a demonstration of the Annual Cycle Energy System (ACES) in an actual building. ACES is an integrated system for supplying space heating and cooling, and domestic hot water to a building through the use of a heat pump, a thermal storage unit, and an outdoor radiative/convective panel. The heat pump extracts energy from a tank of stored water to provide winter heating. The ice that is formed is accumulated for subsequent use in meeting the cooling requirements of the building in the summer. A components test assembly was constructed to measure the rates of heat transfer during ice buildup and brine chilling operations, to assess the design requirements of the evaporator and the desuperheater for producing domestic hot water using refrigerant superheat, and to investigate the mechanical stability characteristics of the ACES freezing coils which are submerged in the water storage tank. The findings of the experimental program are presented and analytical methods for optimally sizing system components according to the thermal characteristics of a building and the climatic zone where it is located are developed. The calculation of the annual coefficient of performance for the ACES is illustrated. |
