Summary

The present paper aims to evaluate the performance characteristics of a split air conditioner working with R-417A under different indoor and outdoor operating conditions. A test facility was constructed and experiments were carried out to achieve the research objectives. The indoor conditions were varied in a wide range of air temperature (21–31.4?°C), air relative humidity (40.3%–61.9%) and air velocity (2.8–4.7?m?s-1) while the outdoor conditions were changed in range of air temperature (35–51.2?°C) and air relative humidity (40.8%–81.2%). Experimental results showed that the increase in the indoor air temperature causes an enhancement in the system coefficient of performance by about 59.7%, while increasing the outdoor air temperature decreases the system coefficient of performance by about 51.6%. The system cooling capacity using R-417A was lower than that of R-22 by about 33.2% at indoor air temperature of 24.5?°C.
