Experimental Research on the Thermodynamic Performance of Heat Pump in Solar-assisted Air-conditioner with Water Heater

Abstract

The research presents a solar-assisted air-conditioner with water heater in which solar water heater and heat pump air-conditioner are combined.The performance of heat pump in the new system is experimentally investigated.The performance of heat pump working at 3 modes under standard condition is measured.The results show that,the COP is 5.34,5.78 and 4.5 at cooling mode,heating mode,and cooling-heating mode,respectively,which indicates that the new system is more effective than traditional systems
