摘要：

An overview of the performance characteristics of possible working fluids in vapour-compression industrial heat-pump systems for medium to high temperature applications is presented. The refrigerants studied include CFC12, HCFC22, HFC134a, HCFC142b, HFC152a, a ternary blend of HCFC22 (40%), HCFC124 (43%) and HFC152a (17%), and NH3. The calculations are made for all the refrigerants for the same operating conditions and are compared with each other. For high-temperature applications, a compression-absorption heat-pump cycle (with NH3-H2O as the working fluid) is described. Its performance characteristics are discussed and compared with vapour-compression cycles with HCFC142b as the working fluid by using the concept of 'thermodynamic temperature'.
