摘　　要：为了提高热泵热水器的效率,搭建了CO2热泵热水器实验台.实验结果表明:在冷却水出水温度为65℃时,CO2热泵热水器的COP随着蒸发温度的升高而升高;在某一蒸发温度下,气体冷却器放热量随着高压压力的升高先升高而后降低,系统的COP存在一个最优值.In order to improve the efficiency of heat pump water heater,a laboratory table of CO2 heat pump water heater is built.The results of experiment showed that the COP of CO2 heat pump water heater rises with the temperature of evaporation increasing when the temperature of cooling water is 65℃.Under a certain temperature of evaporating,the heat release of gas cooler increases with the high pressure increases firstly and then reduces,and the COP of system exists a most value.
