Evaluation of Performance of HFC-R134a/HFO-1234yf Binary Mixtures Used as Refrigerant in a Heat Pump System
Abstract
The use of heat pumps is increasing day by day. So, various refrigerants have been used in the heat pump systems so far. Therefore many studies and arrangements have been made to reduce the environmental effects of refrigerants. The refrigerant mixtures that obtaining from the hydrofluorocarbons (HFCs) and the hydrofluoroolefins (HFOs) are started to be used to reduce of global warming potential of the HFCs and remove flammability of the HFOs in these days. In this study, the performance of R134a/R1234yf (HFC/HFO) mixture in the heat pump was theoretically investigated for different R1234yf mass fractions (from 0.0 to 1.0). The analysis of R134a/R1234yf mixture for different R1234yf mass fraction has made for three different evaporator temperature (-10 oC, -5 oC and 0 oC) and a constant condenser temperature (35 oC). When the R1234yf mass fraction increases from 0.0 to 1.0 the COP value decreases by 2.44% (at the -5 oC evaporator temperature). The R1234yf mass fraction must be 0.9 for the R134a/R1234yf mixture to have lower GWP than 150. Because R134a is has high GWP.
