Analytical Study of Vapour Compression Refrigeration System Using Diffuser and Subcooling

This Paper Presents The Concept Of Analytical Study Ofvapour Compression Refrigeration System Using Diffuser And Subcoolingmainly Carried Out To Improve The Coefficient Of Performance Of System. To Improve The Coefficient Of Performance, It Is To Required That Compressor Work Should Decrease And Refrigerating Effect Should Increase. Initially The Diffuser Of Increasing Cross-Sectional 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. After Result Analysis, We Have Found That The COP Was Enhanced From2.65 To 3.38 In The Case When Conventional VCR System Was Used With Diffuser.
