In the Make India and Green India Program, the use of eco-friendly refrigerants is well demonstrated due to global warming and ozone depletion. This paper highlights the use of R-290 refrigerant is the best alternative and second alternative is R600a. and third is R-152a. Due to flammable nature of these eco-friendly refrigerants, these refrigerants can only be used by using safety measures, otherwise R134a and R410a and R404a are easily available in the markets can be used. The performance of R134a gives better than using R410a and R404a, however for larger Industrial applications R 717 and R744 can be used. Even in mixing of nano-particles mixed with R718 in the secondary circuit and R1234yf for low temperature applications gives better first law and second law performance as compared to R134arefrigerant To replace, R134a, R1234yf (of zero ODP and 4 GWP) and R1234ze (GWP=6, and Zero ODP) are recommended, although these refrigerants gives 5 to 10% less performance than using R134a. Although the performance of R134a is better than R134a using nano particles mixing in R718 but R1234ze can replace R134a for higher temperature applications. The best first law and second law performances have been found using copper nano materials mixed with R718 in secondary evaporator circuit as compared to TiO2 nano particles
