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.
