Abstract

Industries, colleges, restaurants, etc., includes canteens which use refrigerators, water coolers and air conditioners to generate heat during the process of refrigeration. This heat energy is usually wasted. But in this project, we have utilized this heat, to heat the water without an external source of power. The purpose of the project is that, the heated water can be utilized to wash hands and clean utensils in the canteens. Heating the water involves many types of sources like electric heaters, fire, etc. In this project, we use a water-cooled condenser as a heating source to heat the water. During the compression phase of the refrigerant, the refrigerant delivers large amount of heat. This heat is utilized and made as an external water-cooled condenser with a refrigerant coil in the refrigerator along with an air-cooled condenser as a sub-cooler. During this process of refrigeration, only the compressed refrigerant transfers the heat to the water, saves power and thereby produces hot water that finds it to have a good temperature sufficient enough to kill bacteria present in hand and also to wash the utensils in the canteens.
