“…Park et al [33][34][35] measured the thermodynamic performance of R431A, R432A, R433A, and R22 under the same conditions, and demonstrated that both R432A and R433A are good alternatives to R22. Park and Jung [36] found that R170/R290 mixture is also an excellent alternative to R22. Chang et al [37] experimentally investigated the performance of hydrocarbon refrigerants, including propane (R290), isobutane (R600a), butane (R600), propylene (R1270), mixtures of propane/isobutane (R290/600a), and propane/butane (R290/600).…”

“…The COP of binary HC mixtures composed of R290/R600a (in the ratio of 50:50, by mass) and R290/R600 (in the ratio of 75:25, by mass) was reported to be higher than R22 by 7 and 11%, respectively. Park and Jung [28] have investigated the thermodynamic performance of a heat pump working with R22 and its alternative refrigerant mixtures composed of R170 and R290, with five different mass percentage of R170 (2, 4, 6, 8 and 10%). It has been reported that COP of the new refrigerant mixture gets decreased with increase in R170 mass percentage.…”

SUMMARYIn the present paper, an attempt has been made to review the performance of new refrigerant mixtures employed in vapour compression-based refrigeration, air-conditioning and heat pump units. The studies reported with refrigerant mixtures are categorized into six groups as follows: (i) hydrocarbon (HC), (ii) hydroflurocarbons (HFC), (iii) HFC/HC, (iv) hydrochloroflurocarbons (HCFC), (v) carbon dioxide (R744) and (vi) ammonia (R717). This paper explores the studies reported with new refrigerant mixtures in domestic refrigerators, commercial refrigeration systems, air conditioners, heat pumps, chillers and in automobile air conditioners. In addition, the technical difficulties faced with new refrigerant mixtures, further research needs in this field and future refrigerant options for new upcoming systems have been discussed in detail. This paper concludes that HC based refrigerant mixtures are identified as a long-term alternative to phase out the existing halogenated refrigerants in the vapour compression-based systems.

“…Since COP of above mixture was better than R407C [8]. Experimental studies reported that performance of binary mixture R170/R290 (4/96 by mass %) was similar to that of performance of R22 [9]. A detailed review paper suggested that hydrocarbons and its blends were most suitable candidates to air conditioning and refrigeration sectors [10].…”

Abstract. The principal objective of the present study is to compute the thermodynamic performance of window air conditioner based on standard vapour compression refrigeration cycle using R22, R407C and nineteen refrigerant mixtures. In this work nineteen R290/R1270 blends at different compositions are developed. A MATLAB code is developed to compute the thermodynamic performance parameters of all the studied refrigerants at condensing and evaporating temperatures of 54.4 0 C and 7.2 0 C respectively. The performance parameters are cooling effect, compressor work, COP, compressor discharge temperature, power per ton of refrigeration and volumetric cooling capacity respectively. Analytical results revealed that COP of new binary mixture R290/R1270 (90/10 by mass %) is 2.82% higher among R22, R407C and nineteen studied refrigerants. Energy required by the compressor per ton of refrigeration for R290/R1270 (90/10 by mass %) is 2.73% lower among R22, R407C and nineteen studied fluids. The discharge temperature of the compressor for all the nineteen investigated blends are reduced by 6.0-8.9oC compared to R22. Overall thermodynamic performance of window air conditioner with R290/R1270 (90/10 by mass %) is better than R22 with significant savings in energy consumption and hence it is an energy efficient ecofriendly refrigerant mixture as a drop in substitute to R22.
