Steam compression refrigeration is one of the many refrigeration cycles available for use. It has been and is the most used method for air conditioning of large public buildings, offices, private residences, hotels, hospitals, theaters, restaurants and automobiles. It is also used in domestic and commercial refrigerators, large-scale warehouses for refrigerated or frozen food and meat storage, refrigerated trucks and railway wagons, and a host of other commercial and industrial services. Oil refineries, chemical and petrochemical processing plants and natural gas processing plants are among the many types of industrial plants that often use vapor compression refrigeration systems.
Refrigeration can be defined as lowering the temperature of a closed space by removing the heat from that space and transferring it elsewhere. A device that performs this function can also be called a heat pump.
The main goal behind the development of this device is to develop a multifunctional unit that can provide hot, cold water along with the regular cycle of space / air conditioning. The design consists mainly of compressor, condenser, evaporator, expansion valve, copper coil, temperature and pressure gauges. It consists of air cycle and water cycle combined with a common compressor. In the air cycle, heat is transported from a colder place to a warmer area. An air conditioner is an example of such a system, as it transports heat out of the interior and into its surroundings (ie, the room). The refrigerant is used as the medium that absorbs and removes heat from the space to be cooled and then rejects that heat elsewhere. This coolant heat is used to heat or cool the water, which can then be used for various purposes. The air cycle is the conventional steam compression cycle while the water cycle is the adaptation of the same. It consists of five modes: only water heating, space cooling and water heating, heating and water heating, space cooling, space heating. They are controlled by means of valves. A systematic analysis was carried out after completion of the project. The readings were recorded in an appropriate tabular column. Calculations were then made for the determination of air cycle COP, water cycle COP, condenser and evaporator effectiveness, evaporator heat transfer and capillary friction factor.
