Title: System Design and Experimental Study of CO_2 Heat Pump Water Heater
Abstract: A performance testing experiment platform of heat pump water heater of CO2(carbon dioxide) trans-critical cycle has been designed and then constructed,whose evaporator and gas cooler are both sleeve type heat exchanger.When the refrigerant charge is 1.23kg,A preliminary study is conducted.in terms of the performance of the heat pump water heater The results show that:The system can provide hot water whose temperature is higher than 80℃.The COP(Coefficient Of Performance) of system,the outlet temperature and the exhaust pressure are mostly influenced by the water flow of the gas cooler.More efficient heat exchanger can improve the water temperature at the same exhaust temperature of compressor and get a higher COP when producing hot water
