| 摘 要： | 对热回收式CO2制冷系统性能COP进行了计算和分析,结果表明:蒸发温度、气体冷却器出口CO2温度、热水加热器入口水温是影响其COP的主要因素;回热器出口过热度对COP的影响较小,对压缩机的排气温度影响较大;随着排气压力的升高,COP是否出现峰值,取决于气体冷却器入口制冷剂的特征温度;在相同工况下,蒸发温度、气体冷却器出口CO2温度、回热器出口过热度对最佳排气压力的影响较小,热水加热器入口水温是影响最佳排气压力的主要因素。

| Abstract: | A CO2 heat recovery heat pump system was calculated and analyzed.The result from computation and analysis indicated: The COP depends on the evaporation temperature,the outlet temperature of the gas cooler and the inlet water temperature of the hot water heater and etc;The superheat at the outlet of the regenerator mainly affects the compressor discharge temperature and has little influence on COP;With the increases of the exhaust pressure,whether the COP has a peak depends on the characteristic temperature ... |
