The invention discloses a passenger room air conditioner pipeline system based on a heat pump. An outlet of an electronic expansion valve is connected with an inlet of an indoor heat exchanger, an outlet of the indoor heat exchanger is connected with an inlet of an outdoor heat exchanger, an outlet of the outdoor heat exchanger is connected to an inlet of a drying filter, and a high-temperature medium inlet of a heat regenerator is connected with a medium outlet of the drying filter; and a high-temperature medium outlet of the heat regenerator is connected with a medium inlet of the liquid viewing mirror, and an outlet of the liquid viewing mirror is connected with the electronic expansion valve. The flow direction of a refrigerant is adjusted by additionally arranging the ball valve device and changing opening and closing of different ports of the electric two-way ball valve and the electric three-way ball valve so that the heat pump passenger room air conditioner pipeline system is stably and efficiently switched between a refrigerating mode and a heating mode, meanwhile, the functions of the indoor heat exchanger and the outdoor heat exchanger are exchanged, the heating efficiency is high, and the stability and the reliability of the system are effectively improved.
本发明公开了一种基于热泵客室空调管路系统,电子膨胀阀出口与室内换热器入口相连,室内换热器出口与室外换热器入口相连,室外换热器出口连接到干燥过滤器入口,回热器的高温介质入口与干燥过滤器的介质出口相连;回热器的高温介质出口与视液镜的介质入口相连,视液镜的出口与电子膨胀阀相连。通过增加球阀装置,改变电动二通阀球阀与电动三通球阀不同端口的开闭来调节制冷剂流向,进而使得热泵客室空调管路系统在制冷或制热模式之间进行平稳高效地切换,同时还使得室内外换热器的作用相调换,制热效率高,有效提高了系统的稳定性和可靠性。
