Heat transfer rate analysis for ac condenser fines by material g al cu 4img 204, aluminium alloy al99 and magnesium alloy

Abstract


 Air conditioner condensers are a heat exchanger device; AC condenser units are grouped according to how it rejects the heat to the medium (surround air). The primary component of a condenser is typically the condenser coil, through which the refrigerant flows. Since, the AC condenser coil contains refrigerant that absorbs heat from the surrounding air, the refrigerant temperature must be higher than the air. In this project designed an air-cooled Condenser fins for an air conditioner. Presently the material used for coils is Copper and the material used for Fins is Copper or aluminium G Al Cu 4IMG 204 whose thermal conductivity is 110-150W/m K. the condenser fines design using computer aided software catia. We are optimizing the design parameters by changing the thickness of the fin for the same length without failing the load conditions. To validate the temperatures and other thermal quantities like flux and gradient, thermal analysis is done on the condenser fines by applying copper for coil and Fin materials G Al Cu 4IMG 204, Aluminium Alloy Al99 and Magnesium alloy. Heat flux, directional heat flux, convection, Thermal analysis is done in ansys. And also we are varying inside cooling fluid Hydrocarbon (HC) and Hydro chloro flouro carbon (HCFC). The best material and best fluid for the condenser of our design can be checked by comparing the results. Optimization is done by changing the thickness of the catia is a parametric 3D modelling software and ansys is analysis software.
