Summary

The present study aimed to investigate the partial load performance of the residential heat pump using R-32 and HFO blend.Partial load conditions under heating and cooling modes were set according to EN 14825. Optimal charge of R-32 and HFO blend systems was less by approximately 10% than that of R-410A system. EER of R-32 and HFO blend systems at cooling standard condition were higher by 7.0~8.7% and lower by 3.3%~8.7% than those of R-410A system, respectively.EER of R-32 and HFO blend systems at heating standard condition were higher by 2.7%~3.8% and lower by 4.6%~8.0% than those of R-410A system, respectively. Discharge temperatures of R-32 and HFO blend systems were higher by the maximum of 11.9? than those of R-410A system. SEER and SCOP of R-32 system were higher by 7.9% and 8.1% than those of R-410A system, respectively. SEER of HFO blend system was almost the same and SCOP was higher by 5.7% than those of R-410A system, respectively.
