Extraction of Green Energy in R & AC System

M. Yaswanth ^[3]

Abstract: The paper presents trends on recent development of possible substitutes for ecological refrigerants from HVAC & R equipment based on thermodynamic, physical and environmental properties and TEWI (Total Equivalent Warming Impact) analysis. This paper contains a good amount of information regarding the environmental pollution produced by the working fluids of the air-conditioning and commercial refrigeration applications to the ecological refrigerant trend. Overall, it is useful for those readers who are interested in current status of alternative refrigerant development related to vapor compression based refrigeration system for air conditioning, heat extraction sources. The study describes the selection of refrigerants adapted for the utilization based on the thermodynamic, physical and environmental properties and explores the studies reported with new refrigerants in domestic refrigerators, air-conditioners, heat extractors, chillers and in automobile air-conditioners. Additionally, a comparative analysis of the TEWI for possible substitutes of refrigerant R134a used in various air-conditioning, heat extraction sources and refrigeration systems is performed effective manner.
