BEHAVIOR OF ISOBARIC HEAT CAPACITY OF R 32 IN THE GAS PHASE

摘要：

　　The specific isobaric heat capacity (cp) was measured for R 32 (difluoromethane) in the gas phase.Twenty-one measurements for R 32 were obtained at temperatures from 281 to 319 K and at pressures from 1.0 to 2.4 MPa,which are very close to the saturation curve.The expanded uncertainty (k=2) for cp is estimated to be less than 47 J·kg-1·K-1.The data must be useful to represent reliable thermodynamic properties of R 32 and refrigerant mixtures with R 32,which are used for refrigeration and air conditioning systems.
