Experimental Investigation of Cooling Properties of Desert Cooler Cum Refrigerator

Refrigeration is a process in which work is done to move heat from one location to another. Refrigeration has had a large impact on industry, lifestyle, agriculture and settlement pattern.Now a day's people are using cooler, air conditioning system, refrigerator for cooling of room and eatable substance separately. So we are committedto make a project which will help us for many functioning which are doing by three machines. To purchase separate air conditioning, refrigerator and cooler which is not affordable for some people. We also minimize the pollution such as ODP (ozone deflection potential).Anevaporative cooleris a device that cools air through theevaporationof water. Evaporative cooling works by employing water's largeenthalpy of vaporization. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapour (evaporation), which can cool air using much less energy thanrefrigeration. In extremely dry climates, evaporative cooling of air has theadded benefit of conditioning the air with more moisture for the comfort of building occupants
