Enhancement of Coefficient of Performance of Vapor Compression Refrigeration System Using Diffuser at Inlet of Condenser
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
To Enhanced the Coefficient of Performance, It is to require that Refrigerating Effect Should Increase and Compressor Work should decrease. Experimental analysis on vapour compression refrigeration (VCR) system with R134a refrigerant was completed and their results were recorded. The effects of the main parameters of performance analysis such as super heating on the refrigerating effect, power required to run the compressor for various evaporating temperatures, mass flow of refrigerant, percentage increase in COP, coefficient of performance (COP). The results from vapour compression refrigerant plant was taken where the variables like suction pressure of compressor, delivery pressure of compressor, temperature of evaporator and condenser are noted and coefficient of performance is calculated. Initially The Diffuser Of Increasing CrossSectional Area Profile Was Designed, Fabricated And Introduced In Our VCR Apparatus. The Size Of Diffuser Selected Was Of 15 Degree Divergence Angle. By Using Diffuser Power Consumption Is Less For Same Refrigerating Effect So Performance Is Improved. The Size Of The Condenser Can Also Be Reduced Due To More Heat Transfer. So Cost Of The Condenser Will Be Reduced. The Parameters Pressure And Temperature Were Measured.
