Summary

In this study, R290 was poured into a split room air conditioner designed for using R22. The influence of capillary length, outdoor temperature, and refrigerant charge on the air conditioner performance was tested. The distribution of R290 along the loop in the heat exchangers was analyzed. It is found that the cooling capacity of the R290 air conditioner was 99% that of the R22 air conditioner while the EER of the former increased by 10-15%.
