Increasing Trend

With the increase of outlet pressure to compressor, all cycle COP is a reducing trend except R744, in addition, R744 compression cycle has an optimum high pressure. When the inlet temperatures of compressor gradually increase, the performances of all cycles basically unchanged, but the R744 compression cycle has an increasing trend. With the increasing of outlet temperature to the condenser, the performances of all cycles are decreased; instead with increasing of the evaporating temperature, all cycle COP is an increasing trend.

Increasing Trend

With increasing of high pressure, the performances of all kinds refrigerants except for R744 are all declined, transcritical R744 compression cycle has an optimum high pressure. With increasing of the evaporating temperature, all cycle COP is an increasing trend, with increasing of outlet temperature of condenser, the performances of all cycles are decreased. Under the same comparison conditions, the performance of R22 refrigerant cycle is superior to the cycles of other refrigerants, and the cycle of R11 refrigerant has the worst performance.
