Evaluation of Propane as an Alternative to HCFC-22 in Residential Applications
نویسندگان
چکیده
According to the results of the international testing program AREP, the most likely replacements for HCFC-22 refrigerant will be blends of HFCs. However, as concerns about their global warming potential increase, other options should also be considered. As a naturally occurring substance, propane would be an ideal refrigerant, except for its flammability. When dealing with a flammable refrigerant, the manufacturers of systems and equipment have two options: either install the necessary safety features or mix the flammable refrigerant with a non-flammable one to obtain a nonflammable mixture. This article examines both options for residential applications and compares them on a first cost basis with systems that utilize HCFC-22 and many of the leading replacements for HCFC-22.

Theoretical Analysis of Hydrocarbon Refrigerant Mixtures as a Replacement for HCFC -22 for Residential Uses
This paper investigates the feasibility of hydrocarbon refrigerant mixtures as a replacement for HCFC-22 in residential air-conditioning and heat pump systems. The COP and the seasonal performance factor (SPF) were calculated using a UA-model for single component refrigerants and refrigerant mixtures. Simulations were run for pure propane and the mixtures of propane/i-pentane, propane/n-butane,...
متن کاملAssessment of Propane in North American Residential Air Conditioning
Three unitary split systems were evaluated for use with propane as the refrigerant. These three systems were then compared to systems using hydrochlorofluorocarbon (HCFC) R-22 and hydrofluorocarbon (HFC) R-410A for environmental effectiveness. The propane systems included one using safety measures, another using propane with flame suppressant, and one using a secondary heat transfer loop to iso...
متن کاملAzeotrope of HFC-125 and HFC-143a as an Alternative for R-502
R-502 has been the primary refrigerant for low temperature commercial refrigeration applications for many years. The impending phase-out of CFCs dictates its elimination in the very near future. The identification of alternative(s) for R-502 therefore becomes a high priority. This paper addresses the factors to be evaluated in selecting the best replacement and identifies an azeotropic mixture ...
متن کاملEvaluation of HCFC Alternative Refrigerants
It is well-known that HCFC refrigerants widely used in today’s air conditioning and refrigeration (AC&R) industry will soon be phased out, mainly due to their ozone depletion potentials (ODPs) and global warming potentials (GWPs). The timetable established through international agreement and national legislation calls for a 65% reduction of HCFC consumption based on 1989 level by January 1, 201...
متن کاملAn Experimental Evaluation of Flammable and Non-Flammable High Pressure HFC Replacements for R-22
In this paper, the performance of three high pressure HFC refrigerants: R-32, R-41 OA, and R-41 08, is compared to that of R-22. R-32 has excellent thermophysical properties as compared to R-41 OA, R-41 08 and R-22. However, R-32 is a flammable refrigerant while R-41 OA and R-41 OB are non-flammable. The performance of these refrigerants is investigated in a residential heat pump at the test co...
