This research paper conducts a comprehensive thermodynamic performance analysis and comparison between two-stage transcritical refrigeration cycles utilizing Ethane (R170) and Ethylene (R1150). Both are naturally occurring refrigerants having zero ozone depletion potential and low global warming potential which are considered as suitable characteristics. For this study, both compressor pressures are optimized simultaneously. The temp. at gas cooler exit and temp. in evaporator are varied from 35 ℃ to 55 ℃ and –30 ℃ to 0 ℃, respectively. Under the chosen operating conditions, Ethane cycle shows higher COPmax and second-law efficiency compared to Ethylene cycle. The intermediate pressure of Ethane cycle is 39.6% lower than Ethylene cycle. Relations of optimal intermediate, gas cooler pressure, coefficient of performance, and second-law efficiency in terms of temp. in evaporator and temp. at gas cooler exit are derived through cycle simulations. These findings aim to serve as valuable findings for the optimal design, equipment selection, and operation of systems employing these refrigerants.

摘要

This research paper conducts a comprehensive thermodynamic performance analysis and comparison between two-stage transcritical refrigeration cycles utilizing Ethane (R170) and Ethylene (R1150). Both are naturally occurring refrigerants having zero ozone depletion potential and low global warming potential which are considered as suitable characteristics. For this study, both compressor pressures are optimized simultaneously. The temp. at gas cooler exit and temp. in evaporator are varied from 35 ℃ to 55 ℃ and –30 ℃ to 0 ℃, respectively. Under the chosen operating conditions, Ethane cycle shows higher COPmax and second-law efficiency compared to Ethylene cycle. The intermediate pressure of Ethane cycle is 39.6% lower than Ethylene cycle. Relations of optimal intermediate, gas cooler pressure, coefficient of performance, and second-law efficiency in terms of temp. in evaporator and temp. at gas cooler exit are derived through cycle simulations. These findings aim to serve as valuable findings for the optimal design, equipment selection, and operation of systems employing these refrigerants.
