摘要
通过对热泵循环流程的分析,构建了带有回热器热泵的数理模型。理论分析了以R125为工质的热泵系统,并对R125及几种热泵工质在标准工况和变工况下的循环性能进行了系统的理论计算及分析。结果表明,在标准工况下,R125制热系数优于R22,是极有潜力的热泵替代工质。
This thesis has analyzed the cycle process of heat pump, on this basis, the mathematical model of heat pump with regenerator internal heat exchanger is constructed. Theoretical analysis of R125 as refrigerant of heat pump. After systematical calculating and analyzing the cycle performance of the heat pump charged with R125 and several types under standard operating condition and variable operating condi- tions, The results show that the coefficient of performance with R125 is better than R22 under standard, thus R125 can be regarded as a promising alternative of refrigerant heat pump.
