Irreversibility Analysis of R407C, R404A, and R134A as an Alternatives of R22 in Vapor Compression Chiller under Cycling Conditions

This paper presents irreversibility analysis using experimental data from vapor compression chiller system R22, R407C, R404A and R-134A as working fluids. The operated under cycling condition, which allowing the water to circulate in evaporator recording every ten minutes. Further, study was conducted at different ambient temperature identify parameter that cause energy deterioration. findings show total increases high mass flow rate. Additionally, increase of system. R134A R407C are a good replacement for R22 terms during condition.
