Analysis of solar ejector–jet refrigeration system using eco-friendly material r1234yf

Abstract

Air-conditioning of living spaces is indispensable for human beings in the modern life. Ejector cycles are very reliable and simple but their energy efficiency is very low and, therefore, its affect after combining with solar energy can facilitate better system performance. Currently, the vapor compression air-conditioning system uses R134a in the air-conditioning system that is one of the cause of the global warming. In present work, a low global warming potential (GWP) refrigerant material R1234yf is used in the solar ejector-jet refrigeration cycle instead of R134a and its affect on coefficient of performance, refrigerating effect is investigated. Refrigerant R1234yf working fluids provides good energy efficiency and environmental option for solar ejector-jet compression systems and its cycle simulation showed that the proposed ejector-jet cycle can provide energy savings if it is supplied with solar energy.
