摘　　要：The specific heat capacities of HFC152a/HFC32(92%/8% wt) mixture in liquid phase used in the refrigerator as an alternative for CFC12 are determined and 32 values of heat capacity are reported in this paper.The purities of HFC152a and HFC32 are all 99.95%.The flow apparatus for measuring heat capacities of liquid phase compounds and their mixtures under the pressure up to 12 MPa,and at temperatures from 26OK to 47OK was built by the authors.The specific heat capacities of HFC152a/HFC32(92%/8% wt) mixture in liquid phase used in the refrigerator as an alternative for CFC12 are determined and 32 values of heat capacity are reported in this paper.The purities of HFC152a and HFC32 are all 99.95%.The flow apparatus for measuring heat capacities of liquid phase compounds and their mixtures under the pressure up to 12 MPa,and at temperatures from 26OK to 47OK was built by the authors.
