The mixturesR22/142b, R32/124 and R32/134a have been proposed as the working fiuids to adjust thecapacity of the system with load change. The results show that if it is effective to control therefrigerant composition and capacities, the improvements for the seasonal energy efficiencyratio will be obtained.展开更多
Based on the experimental investigation on the PVTx behavior, the thermodynamic properties of HFC125/HFC152a were calculated with a modified form of CSD eqaution of state and mixing rules.
