“…Due to higher volumetric refrigeration capacity use of compressor with lower displacement is required to substitute Propane. The properties of a of HCs using SRK EoS were estimated by Parashurama et al [7] in his earlier work, and the properties obtained are well within permissible limits. Performance was determined and conducted computer simulation to screen hydrocarbons as alternative refrigerants to substitute R12 in medium-sized domestic refrigerator.…”

“…Hence the problem is not resolved and it has to be replaced in accordance with F-gas regulation [10]. In his prior work, Parashurama et al [11] estimated thermodynamic properties of HCs, HFCs and Fluroethers using SRK EOS, screened and proposed R270, R152a and R161 as solutions to R134a with the same compressor and R290 and R1270 with reduced compressor displacement. Isobutane is another leading alternative refrigerant to R12 FOR new manufacturing of domestic and commercial refrigeration appliances.…”

The performance of R290 has been investigated experimentally to replace R12 in a domestic refrigerator with 3.16 cc displacement compressor. A210 litres refrigerator intended to operate with R12 is used in our study with a lower displacement compressor and longer capillary. The consumed energy, temperatures and pressures at salient points the refrigerator circuit and also temperatures at various compartments in the refrigerator are recorded. The experiments are conducted are no load performance test and ice making test with R290 as well as R12 at a surrounding temperature of 30℃. As per our results R290 is the most viable alternative to replace R12 from the view point of energy conservation without the necessity of changing lubricating oil and drier used with R12 but with a slightly lower capacity. The flammability nature can be ignored as the amount of refrigerant used is very low.

“…Hence, Hydrocarbons are viable candidates from view point of heat transfer. Parashurama et al [22] in his previous work predicted thermodynamic properties of HFCs and Fluroethers using SRK EOS, screened and suggested R152a and R161 as alternatives to R134a. Also developed thermodynamic properties of HFCs and HCs using SRK EOS and PSRK mixing rule and recommended several binary mixtures as short term and long term alternatives of R134a [23].…”

The thermodynamic properties of hydrocarbons namely Propane, Cyclopropane, Propene, Methyl acetylene, Propadiene and Dimethyether as alternatives to replace R134a have been predicted using SRK EOS. The values of vapour pressure, liquid specific volume, vapour specific volume, liquid enthalpy, vapour enthalpy, liquid entropy, vapour entropy have been estimated over the temperature range from -250 ℃ to +550 ℃. Simulation of 89W domestic refrigerator is carried out using ten state point vapour compression cycle. The theoretical performances of the hydrocarbons have been comparatively assessed using standard refrigeration parameters. According to our results, Propane, Propene are appropriate and recommended as alternatives of R134a with lower displacement compressor and Cyclopropane as direct substitute. Also implications with respect to material and lubricant oil compatibility, heat transfer characteristics are discussed.
