摘要
介绍了涡旋压缩机闪发器热泵系统,并在结构特点方面与对应的过冷器系统作了比较。对研制的闪发器热泵系统原型机进行了试验研究和性能分析。结果表明:随蒸发温度的降低,原型机的制热量有所减少,但减少的速度明显低于普通热泵系统,压缩机耗功有所增加,但增加的幅度不大;闪发器系统在低温工况下比过冷器系统可以更有效提高空气源热泵的低温制热性能,是寒冷地区用小型空气源热泵比较适宜采用的系统。
The heat pump system with scroll compressor flash-tank is presented, and it was compared with sub-cooler system in structural characteristics. The experimental study and performance andlyses of the heat pump prototype were implemented, and the results showed that the heating capacity of the prototype decreased along with lowering the evaporating temperature, but the decreasing rate is much slower than that of conventional air source heat pump system. The electric power input increased a little at the same time. The heat pump system with flash-tank can improve the heating performances more efficiently than the system with sub-cooler under low ambient temperature conditions, so it is much suitable to the small air source heat pump used in cold area.
