Energy crisis all over the world compelled us to take necessary steps to reduce energy consumption. Heat is energy, so energy saving is one of the key matters from view point of use of refrigerants and for the protection of global environment This waste heat will affect the environmental conditions because as heat in the environment will increases it will cause global warming and also not good for our ozone layer too. By saving energy we balance the demand & supply of electricity. So it is necessary that a significant and concrete effort should be made for conserving energy through waste heat recovery system. We have tried to make a cabinet to recover waste heat from condenser from refrigeration system by storing a heat in an insulated cabinet. As domestic refrigerators reject large heat inside room which make us uncomfortable in summer due to temperature rise inside the room. So it is now essential to reject this heat outside the room or utilize it for different purposes. Rejected heat is used for keeping food hot, heating water which may be used for different purposes. It is valuable alternative approach to improve overall efficiency and reuse the waste heat. The study has shown that such a system is technically feasible and economically viable. This system is nothing but a cabin that we are going to install over the head of the simple evaporator cabin, this cabin will be an arrangement of coils that will store heat which is get eliminated in the atmosphere. These coils are a hot coil of condenser which is wound under the galvanized cabin and will braze with the filter and the evaporator coil which is insulated and fitted in evaporator cabin. It can serve the purpose of cooking (oven), geysers etc. This system rejected less heat to the environment so it is safer in environmental aspects and store large amount of heat in the cabin.
