摘要：
Taking the developed cylindrical spiral phase transition heat-storage evaporator with 30 ℃ phase transition temperature as research object. The characteristics of heat charge and discharge at different outdoor temperature and the defrosting performance were experimentally researched. The results show that the heat-storage evaporator has good heat-storage and heat-release capacity, which can meet the heating demand of heat-storage evaporation air source heat pump in low temperature conditions and solve the contradiction between heat supply and need of air source heat pump effectively, can shorten the defrosting time by 50% and improve the heating effect. The results also show that the speed of heat-storage is slow and the amount of heat accumulation in the limited time is small, in order to achieve higher operation efficiency in very low temperature environment for the heat pump system, some measures must be taken to strengthen the heat transfer of the heat-storage evaporator. ©, 2015, Science Press.
