Thermodynamic analysis of vapour compression refrigeration system using alternative refrigerants
This research is aimed to define , (1) the effects of refrigerant to the environment, (2) derive the eco friendly refrigerants by using software REFPROP, (3) describe the properties of refrigerant by mixing them in appropriate percentage, (4) reducing GWP and ODP by providing suitable substitute of CFC’s and HCFC’s refrigerants, (5) reducing the effect of refrigerant to the ODP. This analysis i...
متن کاملA Performance Comparison of Vapour Compression Refrigeration System Using Eco Friendly Refrigerants of Low Global Warming Potential
A performance analysis on a vapour compression refrigeration system with various eco-friendly refrigerants of HFC152a, HFC32, HC290, HC1270, HC600a and RE170 were done and their results were compared with R134a as possible alternative replacement. The results showed that the alternative refrigerants investigated in the analysis RE170, R152a and R600a have a slightly higher performance coefficie...
متن کاملMethods for Improving Thermodynamic Performance of Vapour Compression Refrigeration System Using Twelve Eco Friendly Refrigerants in Primary Circuit And Nanofluid (Water- Nano Particles Based) in Secondary Circuit
This paper describes thermal modeling of Vapor Compression Refrigeration System using R134a in primary circuit and AL2O3-Water based nanofluids in secondary circuit. The model uses information of the secondary fluids input conditions geometric characteristics of the system, size of nanoparticles and the compressor speed to predict the secondary fluids output temperatures, the operating pressure...
متن کاملNew High Performance, Low GWP Refrigerants for Stationary AC and Refrigeration
In response to concerns about global climate change, and in consideration of probable legislation that may impact the production and use of refrigerants with high global warming potential, a set of new refrigerant candidates has been developed for evaluation. Some candidates are designed for stationary air conditioning in residential and light commercial end uses. Other refrigerant candidates w...
متن کاملComparative Exergy Analysis of Vapor Compression Refrigeration System Using Alternative Refrigerants
Abstract—In present paper, the performance of various alternative refrigerants is compared to find the substitute of R22, the widely used hydrochlorofluorocarbon refrigerant in developing countries. These include the environmentally friendly hydrofluorocarbon (HFC) refrigerants such as R134A, R410A, R407C and M20. In the present study, a steady state thermodynamic model (includes both first and...
