Summary
For the purposes of understanding problems of multiple air-conditioning systems using R22, the authors investigated composition shift of the non-azeotropic mixture and characteristics of the control solution. The results indicated that the composition of R32 in the circulating mixture is a little richer than that in the charged mixture, expecially during heating start-up, but the concentration of R32 remains below the flammability limits, and the control of the non-azeotropic mixture is possible.
