摘要：The performance of a cross-flow, micro-channel condenser of a vapour compression refrigerationsystem subjected to the maldistribution of air flow has been studied analytically.The performance of condenser is studied analytically by changing fins materials when using R22 and R407c.Especially, the material with high thermal conductivity is used as fins material. In this thesis like copper alunminiumand brass are chosen to analyse the performance of fin materials on condenser efficiency.To evaluate heat transfer rate and heat transfer coefficient for the fluids R-22 and R407c with different fins materialsANSYS software is used. Thermal analysis is to determine the temperature distribution and heat flux for all threematerials. 3D modelling is done by Creo-parametric.By comparing results of aluminium and brass with copper fins of condenser, it is observed that using copper as a finmaterial for high cooling capacity and COP of the condenser when using refrigerant R407c. In steady state thermalanalysis thermal error and total heat flux for copper having the significant variation i.e., thermal error = 0.0074696 andtotal heat flux = 22752 W/m2. While considering fluent analysis for R22 and R407c it is absorbed that contours ofenthalpy and contours of static temperature for R407c is giving better results i.e., contours of enthalpy 4200 J/kg andcontours of static temperature 309 k
