Thermodynamic Comparison of R502 and R125 as Vapor Compression Plant Working Fluids
نویسندگان
چکیده
In this paper most significant thermodynamic parameters of R125, based on the propenles data presented in [1, 2]. will be examined and compared with those one of RS02. In fact, after the UNEP ~ontreal Protocol, at the present time the manufacturers and researchers have selected R1 25 as more probable long term substitute of R502 in refrigerating vapor compression plants operating with cold ambient at -40 oc . The comparison should point out the improvements and/or the aggravation resulting from the use of R125. Referring to a standard reversed cycle an exergetic analysis is carried out for both the working fluids. The exergy-enthalpy chart of R125 is presented too.

Dynamical modeling and thermo-economic optimization of a cold room assisted vapor-compression refrigeration cycle
A cold room assisted vapor-compression refrigeration cycle is dynamically modeled in a year and optimized. Total annual cost (TACO) and coefficient of performance (COP) are selected as two objective functions. Both cold room and refrigeration cycle parameters are considered as design variables. Moreover, three working fluids included R22, R134a and R407c are examined. The optimum Pareto front r...

Many fluids of hydrocarbon derivatives were used as working fluids in refrigeration and air conditioning during the past few decades. The phase out of chlorofluorocarbons and hydrochlorofluorocarbons has initiated research on finding an alternative working fluid for the existing. In this article, some working fluids with zero ozone depletion potential have been assessed for their suitability as...
