Successive Improvement of Refrigerants in Vapour Compression Refrigeration System for Sustainable Environment

Abstract

In the present paper, it is presented about the drastic changes in refrigerants in VCRS from the past days keeping in mind the need of changing the past refrigerants due to the rapid depletion of our Ozone layer.
When the depletion of Ozone layer was observed increasing day by day Montreal Protocol was signed for prohibition of the use of the refrigerants like CFC, HCFC, HFC and their derivatives were prohibited worldwide.But the need of refrigerants were increasing rapidly day by day so new refrigerants were discovered like R-11, R-22 and many more which are efficient enough and eco-friendly too.
In this paper, it is also presented that the new drastic changes in the introduction of new refrigerants like R-410 A and R-417 A. Their efficiency, drawback, new implementations are also introduced in this paper.
