In this paper, the properties and energy saving protential of a capacity control systemby varing the composition of a mixture has been analysized and experimented. 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.
