Abstract

The current work presents the exergy analysis of dedicated mechanically subcooled vapour compression refrigeration system. It involves the performance comparison of dedicated mechanically subcooled cycle (DSC), overall cycle (OC), subcooler cycle (SC) and simple VCR cycle using HFO-R1234ze, R1234yf and HFC-R134a. A computational formulation model has been developed in the EES software for the computation of various performance parameters, viz. COP, exergetic efficiency, exergy destruction rate and exergy destruction ratio. The effect of variation of effectiveness of subcooler (0.3–1.0) and isentropic efficiency of compressors (0.1–1.0) has been investigated on the performance of the cycles. Exergy destruction in each system component has also been checked. It has been observed that performance wise, the dedicated mechanically subcooled VCR cycle is an improved version of simple VCR cycle. The overall cycle also performs better than simple VCR cycle. The HFO-R1234ze competes with HFC-R134a and supersedes R1234yf. It proves itself a good alternate to R134a being a friend of the environment. Condenser1 is the most sensitive system component of dedicated mechanically subcooled VCR cycle for the refrigerants considered.
