Performance of two ozone-friendly refrigerants (R410A and R419A) was investigated theoretically using computational thermodynamic analysis. The results obtained showed that the performance of R410A was very close to that of R22 in all the operating conditions. Both R22 and R410A performed better than R419A in terms of their COP and refrigerating effect. Compared with R22, the average COP and refrigerating effect of R419A are lower by 13.78 and 33.96%, respectively. Generally, R410A refrigerant has approximately the same performance with R22, therefore, it is considered as a good drop-in substitute for R22 in vapour compression air-conditioning system.
