In this study, the first and second law analysis of Dimethyl ether (DME) and its blend refrigerants (R429A, R435A, R 510A) is presented as an alternatives to R134a. A computational model, developed in cycle_D software, is employed for comparing the performance of these refrigerants in vapour compression refrigeration cycle. The thermodynamic proper...

This paper presents the theoretical investigation of effects of sub-cooling on the performance of eco-friendly alternative refrigerants (R152a, RE170 (Dimethyl ether) in a domestic refrigeration system. The study was performed using a vapour compression system with the aim of 􀃶nding a drop-in replacement for R134a. An increase in sub-cooling effect...

¬This study deals with the Thermodynamic evaluation of the use of Di-methyl ether refrigerants in household refrigeration systems which utilize R134a as a working fluid. A theoretical computational analysis was developed for R134a, Di-methyl ether (RE170) and the selected mixtures (R429A, R435A and R510A) in the standard refrigeration cycle ASHRAE,...

This communication deals with the exergetic analysis of a vapour compression refrigeration system with selected refrigerants. The various parameters computed are COP, exergetic efficiency and EDR in the system. Effects of condenser temperature, evaporator temperature and sub-cooling of condenser outlet, super-heating of evaporator outlet and effect...

In this paper the performance of a vapour compression refrigeration system with ZrO2 nanoparticles in the working fluid was studied. Nano refrigerant was synthesized on the basis of the concept of the nanofluids, which was prepared by mixing ZrO2 nanoparticles with R152a refrigerant. The conventional refrigerant R134a has a global warming potential...

In the present study, the possibility of using refrigerant blend of RE170 and R600a as alternative to the refrigerant R134a in domestic refrigerator working on Vapour Compression System has been assessed theoretically. R134a is currently used as the refrigerant in refrigerator replacing the ozone depleting refrigerant R12. Although R134a has no ozo...

R-134a is currently used as the refrigerant in refrigerator replacing the ozone depleting refrigerant R-12. Although R-134a has no Ozone Depletion Potential (ODP), it has a relatively larger Global Warming Potential (GWP) of 1300. In an effort to reduce greenhouse gas emissions, R-152a (difluoroethane) (GWP 130) and Hydrocarbons (GWP 20) are being...

The parametric investigations of actual Vapour Compression Refrigeration (VCR) cycle in terms of Coefficient of Performance (COP), Exergy Destruction (ED) and exergetic efficiency of refrigerants R134a, R152a and RE170 have been predicted with the help of vapour compression cycle design software (CYCLE_D4.0). The present investigation has been carr...
