摘要：

The paper presents a comparative thermodynamic analysis of seven candidate vapour-compression heat pump working fluids, namely R-11, R-12B1, R-21, R-113, R-114, R-142b, and R-216. The basis for evaluation is the temperature-boost/pressure-penalty ratio and the heat of vaporization. Four of the above refrigerants are covered under the Montreal Protocol. It is observed that R-21 and R-216 are effective alternatives for low grade heat recovery and R-142b for comfort heating. The fluids are compared for ideal operating temperature limits of each refrigerant as well as a fixed range of 30 to 100-degrees-C.
