Air Conditioning cum Water Dispenser System

This project AIR CONDITIONING CUM WATER DISPENSER SYSTEM makes the study of the development of a water dispenser system using a normal air conditioner. The main aim behind developing this device is to develop a multifunctional unit which can provide hot water, cold water along with regular space/air conditioning cycle. The design mainly consists of compressor, condenser, evaporator, expansion valve, copper coil, temperature and pressure gauges. It comprises of air cycle and water cycle combined with a common compressor. In the air cycle, heat is transported from a colder location to a hotter area. An air conditioner is an example of such a system, as it transports the heat out of the interior and into its environment (i. e. the room). The refrigerant is used as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. This heat of the refrigerant is used to heat or cool the water, which can be then used for various purposes. The air cycle is the conventional vapor compression cycle whereas the water cycle is the adaptation of the same. It consists of five modes- water-heating only, space cooling and water heating, space heating and water heating, space cooling, space heating. They are controlled by means of valves. Systematic analysis after the completion of project was carried out. The readings obtained were noted down in a proper tabular column. Then calculations for determination of COP of air cycle, COP of water cycle, effectiveness of condenser and evaporator, heat transferred by evaporator and friction factor of capillary tube were carried out.
