| Abstract: | The phase-change heat storage device is used as principal low-temperature heat source during defrosting to improve the defrosting capacity of air-source heat pump. Under the moderate/severe frosting conditions, the variations in surface temperature of heat exchanger for outdoor machine, phasechange material temperature, compressor suction and discharge pressure and surface temperature of heat exchanger for indoor machine with defrosting time are experimentally studied to evaluate the defrosting capacity of air-source heat pump using phase-change heat storage device. |
