Obtains the performance curves with the change of working conditions for the systems using R22 and R32/R134a as refrigerants respectively by simulation. Compared with the system of R22 at the same working condition, the R32/R134a system has higher heating COP and lower heating capacity and power consumption,which indicates that R32/R134a replacing R22 has advantage in energy efficiency.
