摘　　要：为研究CO2在热泵领域的应用,设计并搭建了CO2跨临界循环水源热泵系统试验台,研究系统在不同工况下运行的性能参数.试验结果表明:在水源温度为30℃,初始水温度为25℃,蒸发温度为10℃,终止水温度为60℃和65℃,蒸发器侧的水热源流量为0.6 m3/h条件下,系统COPH随着高压侧压力的升高,呈现出先升高后降低的趋势,最大COPH为4.4,与其相对应的高压侧压力为最优高压侧压力.In order to study the application of CO2 in the heat pump,the experiment units of tans-critical CO2 water source heat pump system was designed and built,and the performance of system in various conditions was studied.The experiment results showed that when the initial temperature of water is 25 ℃,the evaporation temperature is 10 ℃,the temperature of water resource is 30 ℃,and the termination temperature of water is 60 ℃ and 65 ℃,the heat water source flow of evaporator side is 0.6 m^3/h,the COPH of system increases first and then decreases with the high-pressure,the maximum is 4.4,and the high side pressure corresponding to it is the optimal.
