| 摘 要： | 对跨临界CO2水-水热泵多种工况的循环性能进行试验研究，获得一系列试验数据。试验结果表明，1）跨临界CO2热泵循环在高温热泵领域可得到高于常规热泵系统的制热系数；2）降低气体冷却器出口温度，提高蒸发温度，选择最佳的高压侧压力可有效提高系统的制热系数。最后根据试验结果为今后CO2热泵流程设计提出一些建议。

| Abstract: | Carries out series of experiments for a heat pump water heater system using CO2 transcritical cycle. Experimental results show that the transcritical CO2 cycle is advantageous over those conventional refrigerants cycle, especially in high temperature heat pump fields. According to the analysis of the experimental data, the outlet temperature of gas cooler, evaporation temperature and compressor outlet pressure are three influencing factors of system performance. |
