Résumé

R-410A is a long-term alternative refrigerant with zero ODP (ozone-depleting-potential) for replacing R-22. In this paper, four sets of comparable R-410A and R-22 split-type residential A/C (air conditioners) were developed and then their performance was comparatively studied using one simulation software. The A/C performance compared in this paper included the cooling capacity, EER (energy efficiency ratio), annual power consumption of A/C and the global warming impact of refrigerants adopted by the A/C. It was concluded that the adoption of R-410A could be helpful for A/C to decrease their heat exchanger size or improve their operation efficiency for power saving. Moreover, compared to R-22, R-410A could in fact help alleviate its overall impact on global warming through significantly reducing the indirect global warming impact caused by operating R-410A A/C.
