Analysis of R410A and R404A in Domestic Refrigerator

Abstract

In this work, an experimental work was investigated on the R-410A and R-404A which are eco friendly refrigerants and have zero ozone depletion potential and low global warming potential than R-134a used in a domestic refrigerator without any system reconstruction. The refrigerator performance was then investigated using energy consumption test and freeze capacity test. The results indicatethat R-410A and R-404A work normally and safely in the refrigerator. The refrigerator performance was better than the pure R404A, thus R-410A refrigerant in domestic refrigerators is feasible and can replace the R-134a. To do experiment some parameters like food compartment temperature, freezer compartment temperature, operating pressure, compressor temperature, condenser temperature are taken and performance analyzed.
