Time is insufficient for everyone in this express world. In the meantime, we have to concentrate on our environment for the betterment of humans and other species in the world. Ozone depletion and global warming are main disturbances for the good environmental condition. These disturbances are mainly occurring due to refrigerants which are having high GWP and ODP values. Hence, we need to find a substitute for present refrigerant in terms of low GWP and zero ODP values. In this paper, we summarized the results of researchers to find out a new refrigerant. Finally, after analyzing those results we found that the following refrigerant R290/R600a having zero ODP and very low GWP will give better COP, high cooling capacity and low energy consumption.
