“…Jung et al [7] examined the performance of a propane/isobutene mixture for domestic refrigerators. They have found in their study that the thermodynamic cycle analysis of propane/isobutane mixture in the composition range of 0.2-0.6 mass fraction of propane yielded an increase in the coefficient of performance (COP) of up to 2.3% as compared with CFC12.…”

SUMMARYHydrocarbons (HCs) are excellent refrigerants in many ways such as energy efficiency, critical point, solubility, transport and heat transfer properties, but they are also flammable, which causes the need for changes in standards, production and product. There are increasing number of scientists and engineers who believe that an alternative solution, which has been overlooked, may be provided by using HCs. The main objective of this study is to perform energy and exergy analyses for a vapor compression refrigeration system with an internal heat exchanger using a HC, isobutene (R600a). For a refrigeration capacity of 1 kW and cold chamber temperature of 08C, energy and exergy balances are taken into account to determine the performance of the refrigeration system. Energy and exergy fluxes are determined, and irreversibility rates are calculated for every component of the system. It is seen that the compressor has the highest irreversibility rate, and the heat exchanger has the lowest. Also from the result of the analysis, it is found that condenser and evaporator temperatures have strong effects on energetic and exergetic performances of the system such as coefficient of performance (COP), efficiency ratio (t), exergetic efficiency (x) and irreversibility rate.

“…The hydrocarbon mixture with 50% propane, 38.3 % butane and 11.7% isobutane shows better performance among all other hydrocarbon mixtures investigated. Experimental results of Jung et al (2000) indicated that the mixture of propane and iso-butane with 60% mass fraction of propane has higher COP, faster cooling rate, shorter compressor on-time and lower compressor dome temperatures than that of R12. Akash & Said (2003) conducted performance test with LPG (30% propane, 55% n-butane and 15% iso-butane by mass fraction) as a possible substitute for R12 in domestic refrigerator.…”

Abstract. In this paper, the performance of hydrocarbon mixture refrigerant R290/R600 (79/21 by wt %) has been analyzed as an alternative to R12 and R134a. Experiments are conducted with R12, R134a and R290/R600 mixture refrigerant at different condensing and evaporating temperatures and at various compressor speeds. Further, the statistical models are developed using design of experiments technique for the prediction of refrigeration system parameters such as refrigerating capacity, power consumption and coefficient of performance. The models developed are checked for their adequacy using F-test. The performances of vapour compression refrigeration system with various refrigerants R12, R134a and R290/R600 are compared. The R290/R600 mixture shows 19.3-27.9% higher coefficient of performance than that with R12 and R134a and it is found that the hydrocarbon mixture with 79% propane and 21% butane can be used as a substitute for R12 and R134a. .

“…India and China are the largest refrigerator demanding countries in the world, have been quite active in the application of hydrocarbons in domestic refrigerators. The assessment of alternative refrigerants is a difficult task [7]. Several criteria must be considered while selecting alternative refrigerants.…”
