Abstract

R-22 is a very commonly used refrigerant having wide applications. We have a big challenge to
replace R-22 because of HCFCs, which deplete the ozone layer and harmful to the environment. As
per Montreal Protocol we promised to be banned by 2020. Since being an unconventional &non ecofriendly
product it is being replaced by R-134a. Nano Al2O3 gives better performance hence it is
succeeded after R-22. Refrigerant R-134a is currently being used in every sector of industries, as a
part of Nano element it was accepted having multipurpose use in less quantity. Being less in quantity
& economical aspect considered it to be an influencing refrigerant till date. Having Al2O3 a metal
component reduces its efficiency from being heated immediately, thus a new & more improved
world-wide experimented refrigerant R-744 is introduced. Various eco-friendly & non ozone
depleting refrigerant R-744 is manufactured by recycling the Co2 from atmosphere. It does not
consist of any CFCs, hazardous chemicals and also available at cheap rate. Hence it is proving an
efficient & sustainable refrigerant at current era. So, threw the present paper the highlighted study on
compression refrigeration system is discussed.
