Performance Evaluation of Micro channel Condenser in Vapour Compression Refrigeration System Using Low GWP Refrigerants

Abstract

newline The majority of household refrigerators employs vapour newlinecompression refrigeration technology and has high coefficient of newlineperformance with respect to others. The system is put together using newlinecomponents such as the condenser, compressor, evaporator, and newlineexpansion valve. The performance of the system is determined by newlineindividual component, and each component has the ability to push newlinesystem performance up or down. The performance of the condenser and newlinerefrigerant has been investigated. newlineThe literature review of vapor compression refrigeration system newlinewas studied. The review mainly focuses on the advancement in VCRS newlinecomponents, refrigerant and microchannel condenser. The properties of newlinedifferent refrigerant have been examined such as.R134a, R400a, R744, newlineR1234yf, R1234ze, and R600a.The effect of these parameters on newlinerefrigeration performance parameter like condenser capacity, newlinerefrigeration capacity, and COP was studied. The review was conducted newlinefor the microchannel heat exchanger. The effect of microchannel newlinecondenser was studied along with its use in refrigeration system. From newlinethe literature review, research gap has been identified and aim and newlineobjective of research are defined. newlineThe methodology adopted for the research was elaborated in newlinedetails. 1TR of vapor compression refrigeration system was designed. newlineTwo different size of microchannel condenser were designed for 1TR newlinerefrigeration system. Three different refrigerant were selected for the newlinetesting i.e. R134a, R600a and R1234yf. All experimentation was newlineconducted at different evaporative temperature i.e. -100C, -50C, 00C, newline50C, 100C and 150C. For the experimentation and analysis full factorial newlinemethod was used and 42 combinations were tested. newlineIn the experiment it is found that, use of micro channel condenser newlinerequires less amount of compressive work than conventional and it newlinevi newlineresults in decrease in the diameter of condenser, amount of work is also newlinedecreases. It has been discovered that using a microchannel condenser newlineboosts condenser capacity, refrigeration capacity,
