Experimental Investigation on the Effects of Vapor Injection on Defrosting Performance Improvement of Quasi-two Stage Compression Air-source Heat Pumps

Zhileng xuebao, 2023
During reverse-cycle defrosting of an air-source heat pump, the defrosting time is always long owing to insufficient heat sources. For the quasi-two stage compression air-source heat pump (QTASHP), owing to its larger outdoor coil operated at lower ...

Research on Defrosting System of Air-source Heat Pump with Liquid Storage Gas-liquid Separator

Zhileng xuebao, 2022
The surface of an outdoor evaporator can easily frost when an air-source heat pump is used for heating during winter. The most common defrosting method, reverse cycle defrosting, has safety risk and long defrosting period.
