Experimental study on performance of quick starting air-source heat pump with domestic water heater

In order to solve the problem of slow starting of air-source heat pump water heater, puts forward the quick starting system and develops the test bed. Analyses the cause of slow starting, and presents the principle of quick starting system and testing system. Measured data show that the launching time can be shortened to 4 min, and overall COP can be improved to 7.2.
