【 摘 要 】

A method of refrigeration utilizing photovoltaic-thermal (PVT) solar heat pump is proposed, and long-wave radiation cooling is the key point. The PVT solar heat pump system combined cooling, heating and power (CCHP) is designed and constructed. The refrigeration performance of PVT solar heat pump during summer night is experimentally tested, including chilled water making and ice making. The refrigeration performance difference between clear sky night and cloudy sky night is compared and analyzed. The environmental condition more suitable for refrigeration is given according to the comparison result.
