Experimental research on performance of air-source heat pumps

Through establishing test rig and measuring equipment for air-source heat pump systems, conducts the experiments under different conditions. Analyses the influence of the inlet water temperature of condenser and condensation temperature on heat exchange capacity, heating capacity, compressor conditions and system COP. The results show that system COP can reach 3.4 when inlet air temperature of evaporator is fixed at 9.3 ℃ and condenser inlet water temperature is controlled between 26 ℃ and 45 ℃.
