R32 the Future Refrigerant

EasyChair Preprint no. 2629

Abstract

       In early 2010 the manufacturing and distribution of R22 refrigerant was banned. Due to its increasing effect on the environment with the production of CFC gases, depletion of ozone layer had lead to rise in global warming. R22 refrigerant which was used commonly in AC systems has had a major impact on air conditioning costs. Initially R134a and then R410a were replaced with R22 refrigerant in the industry due to the Montreal protocol. In this paper there is a detailed study done of R32 refrigerant along with its chemical and thermodynamic properties and its comparison with the refrigerants currently used in the refrigeration industry.

  The main motive of this research paper is to examine the performance characteristics of all the current used refrigerants and compare it with R32 refrigerant, so as to replace it with currently used refrigerant. The study involves a detailed analysis of refrigerating effect, heat output, work input of compressor and COP of the system for various refrigerants. The result has shown that R32 has very higher refrigerating effect when compared to R410a and hence a better COP is resulted with R32 refrigerant for low temperature working condition R32 refrigerant is very effective in improving the poor heat capacity of heat pump water heater. From these analysis we can conclude that R32 refrigerant is clearly better replacement alternative in RAC system.
