Summary

The development of efficient vapor compression systems represents a significant technical opportunity for the decarbonization of the refrigeration, air conditioning, and heat pump sector. An effective construction method for vapor compression cycles should be able to simultaneously optimize the refrigerant selection, cycle structure and cycle parameters simultaneously. In a previous study, the authors proposed the GraPHsep method, which has been demonstrated to overcome the constraints of existing methods. The GraPHsep method is capable of automatically constructing optimal vapor compression cycles with corresponding optimal refrigerants under certain application scenarios. In this paper, the GraPHsep method is applied to construct an efficient air conditioner using the zeotropic refrigerant R32/R1234yf. Based on that, a prototype system is developed. The experimental results demonstrate that the seasonal energy efficiency ratio (SEER) of the new system reaches 5.64, which is 24.7% higher than that of the conventional system using R32.
