光伏光热一体化装置与热泵结合系统的影响因素分析

Analysis of influencing factors for a hybrid photovoltaic/thermal and heat pump system

光伏光热一体化装置与热泵结合系统,既能产生电能,又可以回收热能。利用修正Hottel-Whillier模型,结合理想制冷循环,建立了光伏光热一体化装置与热泵结合系统的数学模型。通过对制冷剂流量、辐射强度及水箱水温等影响因素的分析,确定合适的蒸发温度、冷凝温度、制冷量等参数,为选择合适的节流装置和压缩机提供理论依据。

A hybrid photovohaic/thermal and heat pump system （PV/T-HP） can generate electricity as well as recover thermal energy. The mathematical model of PV/T-HP system is established by ex- tension of the Hottel-Whillier model and ideal refrigeration cycle. After analyzing influence factors such as refrigerant flow, solar radiation intensity and water temperature etc., the appropriate evaporating temperature, condensing temperature, cooling capacity and other parameters have been determined, which provide a theoretical basis for the selection of the appropriate throttling device and compressor.
