The invention discloses a new energy automobile heat pump air conditioner defrosting system utilizing a phase change material to store heat. The system comprises an in-vehicle heat exchanger, an out-vehicle heat exchanger and a compressor, a heating circulation loop and a refrigerating circulation loop are formed between the compressor and the in-vehicle heat exchanger and between the compressor and the out-vehicle heat exchanger through a four-way reversing valve, and the system further comprises a plate heat exchanger located in a vehicle. And the plate heat exchanger is connected in series between the external heat exchanger and the compressor to form a defrosting circulation loop and can supply heat to the external heat exchanger for defrosting through the plate heat exchanger when the internal heat exchanger is closed. The defrosting device has the advantages that condensate water cannot be generated, water mist cannot be generated, driving cannot be affected, the problem that a short-time refrigeration effect is achieved in the traditional defrosting process is effectively solved, and the comfort of the environment in a vehicle and the driving safety are improved. The problems of low energy efficiency, frosting and defrosting of an electric air conditioning system under the low-temperature climate are effectively solved, and the purposes of comprehensively adjusting the temperature and the humidity in the vehicle and improving the comfort in the vehicle are achieved.
本发明公开了一种利用相变材料蓄热的新能源汽车热泵空调除霜系统。它包括车内换热器、车外换热器以及压缩机,压缩机经过一个四通换向阀分别与车内换热器和车外换热器之间形成有制热循环回路和制冷循环回路,还包括一个位于车内的板式换热器,板式换热器串接在车外换热器和压缩机之间形成除霜循环回路并能够在车内换热器关闭时通过板式换热器给车外换热器供热进行除霜。有益效果是:不会产生冷凝水从而产生水雾影响驾驶,有效避免了传统上除霜过程中伴随短时间制冷效果的问题发生,提高了车内环境的舒适性以及行驶安全性。有效解决了电动空调系统低温气候下能效低、结霜除霜的难题,也实现了车内温湿度全面调节、提高车内舒适性的目的。
