Abstract
In many automotive industries for various washing machines, temperature of water used to clean the parts is a very important requirement. The method to heat the water for this washing process was previously accomplished by using various water heating methods such as by Electrical Resistance Heating method, HSD/LPG Fired Boiler, NG Fired Boiler. This method can now be replaced by an Energy Efficient Heating technique using Heat Pump. Heat Pump is one such device which gives an output three times than that of the input energy. An outlet water temperature of about 650C can be obtained from this method. Now this technique can be used to heat the water required for the washing process by inculcating a few modifications in the system. The modifications include replacing the present water heating system by Heat Pump water heating system. This can be achieved by proper base lining and detailed analysis of the present system. In the present work the electrical resistance water heating technique is being replaced by a heat pump system, which is done by gathering the electrical consumption data of the electric heaters. This electric consumption plays a vital role in sizing the heat pump. Once the heat pump sizing is completed this can be further used to obtain the size of hot water circulation pump by taking a fixed temperature difference into consideration. Few modifications has to be done in the tank containing hot water i.e. a helical coil heat exchanger will be designed based on the running load of the tank. Before designing the helical coil the various losses in the tank has to be found and based on this load heat exchanger designing process will begin. In this system the Heat Pump will be used to heat the water in two tanks but the design of the Heat Exchanger has been done only for one tank. Based on the various losses from the tank the total running load required to maintain the water temperature of the machine1&2 at 650 C was 30kW. Heat Exchanger design was modeled by considering the previous result of the running load of the hot water storage tank.
