Performance Analysis of Two Stage Compression Cycle with an Internal Heat Exchanger

Abstract:

With increasing of the evaporating temperature, the two stage compression cycle with an internal exchanger’s COP has an increasing trend. In addition, R744 achieves the highest COP, and the R12 achieves the minimum level. With increasing of the high pressure and the outlet temperature of the condenser, the two stage compression cycle has a down trend. In terms of the increasing intermediate pressure, the two stage cycle with different refrigerants has different performance: R12’s COP has a downtrend with the pressure changing from 1MPa-3MPa, the rest refrigerants all increased first, and then decreased. Except for R12, they all have optimal intermediate pressure.
