Abstract
The global warming and ozone depletion are serious issues and search for newand ecofriendly refrigerants for reducing global warming. The methods forimproving first law and second law efficiency have been considered by mixingnano particles mixed in secondary evaporator circuit with R718 and newelydeveloped ecofriendly refrigerants of low global warming potentials isproposed in this paper. Detailed energy and exergy analysis of vapourcompression refrigeration systems have been carried out using R1234yf (of GWP=4) and R1234ze (of GWP=6) in terms of performance parameter forvarious ecofriendly refrigerants for replacing R134a and otherrefrigerants after 2030. The numerical computations have been carried out for variablecompressor speed vapour compression refrigeration systems. It wasobserved that first law and second law efficiency improved by 25% bymixing Copper nano particles in the R-1234yf and 18% using R1234zeecofriendly refrigerants in the primary circuit of vapour compressionrefrigeration systems.
