| 摘 要： | 为了解决R32/R134a应用于变浓度热泵系统存在的排气温度过高问题,提出使用三元混合工质R407C用于该系统中.以R32/R134a和R407C作为工质在变浓度容量调节热泵系统中进行了吸气压力不变时的变浓度实验.实验结果表明,R407C在本系统中变浓度范围低于R32/R134a,但R407C的排气温度和耗功均低于R32/R134a,具有良好的变浓度调节潜力.

| Abstract: | R407C was proposed to reduce high discharge temperature caused by R32/R134a when operated in the heat pump system with variable composition.The experiments on the performances of both R407C and R32/R134a were respectively done which were used in the system as the suction pressure was fixed.The experiment results show that the variable concentration range of R407C is smaller than that of R32/R134a,but the discharge temperature is lower and the power consumption is less than that of R32/R134a,which indicates ... |
