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

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

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 ambient temperatures, a considerable amount of heat...
