| 摘 要： | 跨临界热泵循环在大温差加热时具有显著优势。为了寻求更高效的跨临界热泵循环,对R23跨临界热泵循环进行了理论分析,计算了压缩机排气压力对系统性能的影响。计算结果表明,R23热泵系统存在最优高压侧压力,最优高压侧压力与制冷剂气冷器出口温度、蒸发温度、过热度都有关系,其中以制冷剂气冷器出口温度对最优高压侧压力影响最大。以制冷剂气冷器出口温度为自变量,利用多项式函数对最优高压侧压力进行了拟合,拟合的最大相对误差为-3.14%,平均相对偏差为1.22%。结果可以为R23跨临界热泵系统的设计和控制提供理论参考。

| Abstract: | It is efficient for transcritical heat pumps to heat the second fluid to a high temperature.In order to seek more efficient transcritical heat pump cycle,the transcritical R23 heat pump system was analyzed theoretically and the heat rejection pressure was calculated in this paper.The results indicate that there is an optimal heat rejection pressure,which mainly depends on the R23 temperature in the gas cooler outlet,and also the evaporation temperatures and the superheat degree.The optimal heat rejection pr... |
