摘要
针对空气源热泵热水器在低温环境下不能稳定运行的现象,分别将闪蒸器和过冷器用于热泵系统,在一定程度上解决了传统热泵系统在低温环境下运行时存在的问题;对使用工质R22和R410A的热泵循环分别进行了理论计算,并对结果进行了分析。
For the phenomenon that air source heat pump water heater can not work steadily at low temperatures, the flash evaporator and sub-cooler were respectively used in the system. To a certain extent,it solved the problems when the heat pump system worked at low temperature. Then the heat pump cycles, which used R22 and R410A as refrigerant, were respectively calculated theoretically and the results were also analysed.
