Experimental comparison between R134a/R744 and R438A/R744 (drop‐in) cascade refrigeration systems based on energy consumption and greenhouse gases emissions

Abstract This experimental study evaluates the energy performance and climatic changes of a cascade cooling system operating with the R134a/R744 pairs (cooling capacity of 4.5‐6 kW) and R438A/R744. In both cases, the low‐temperature refrigerant, R744, operated under subcritical conditions. The exper...
