Abstract
Air Conditioner (often referred to as AC) is a home appliance, system, or mechanism designed to dehumidify and extract heat from an area. In construction, a complete system of heating, ventilation and air conditioning is referred to as HVAC. Air conditioning evaporator works by absorb heat from the area that need to be cooled. It does that by maintaining the evaporator coil at low temperature and pressure than the surrounding air. Since, the AC evaporator coil contains refrigerant that absorbs heat from the surrounding air, the refrigerant temperature must be lower than the air. The main aim of present work is to do thermal analysis on evaporator with selected fin material and refrigerant. 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. For present work the copper plate, Al99 (1100) and Al 204 plate material is used for fin. To validate the temperatures and other thermal quantities like flux and gradient, thermal analysis is done on the evaporator coil by applying properties copper and present fin material. And also we are varying inside cooling fluid Hydrocarbon (HC) and Hydro chloroflouro carbon (HCFC). The best material and best fluid for the evaporator of our design can be checked by comparing the results. Thermal analysis is done in ANSYS. Finally result extracted from simulation is analyzed for its performance.
