Air conditioning systems have condenser that removes unwanted heat from the refrigerant and transfers that heat outdoors. 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 my paper I have designed an air-cooled Condenser for an air conditioner. Presently the material used for coils is Copper and the material used for Fins is Copper or aluminum G Al Cu 4IMG 204 whose thermal conductivity is 110- 150W/m K. A 3D model of the condenser is done in parametric software Pro/Engineer. To reduce the cost of condenser, 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 by applying copper for coil and Fin materials G Al Cu 4IMG 204, Aluminum Alloy Al99 and Magnesium alloy. Thermal analysis is done in Cosmos works. And also we are varying inside cooling fluid Hydrocarbon (HC) and Hydrochloroflourocarbon (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 fin.Pro/Engineer is a parametric 3D modeling software and Cosmos works is analysis software.
