As the vapour compression refrigeration system has being utilized worldwide in domestic as well as industrial purpose. Waste of energy in terms of heat through condenser is exposed directly into the environment which has been the major issue in global warming of earth. So for reducing the waste of energy into the environment the existing model associated with maximum utilization of waste heat via installation of water chamber in between compressor and condenser. The recovered hot water could be put to use for home purpose like heating water, bathing, washing in addition to large scale industrial purpose like fabricating, processing, diluting, incorporating water into product or perhaps for sterilization necessities that has nominal constructional, renovation and operating cost, substantially useful for domestic intent. In a vapour compression water cooling system, a box has situated after compressor as water where heat of hot vapours from compressor was utilized to heat the water and then after it supplied to air cooled condenser which exposed to the environment. Experiments were conducted for cases of free and forced convection of water in heat pump and parameters as temperature of water in water cooler, heat pump, condenser temperature and COP of refrigerator and heat pump were recognized and compared. After conducting the experiment, conclusions were drawn that the minimum evaporator temperature was found 3°C in free convection and 2°C in forced convection at 02:15.p.m. The maximum temperature of heat pump was found 62°C in free convection. The temperature heat pump was found 63°C at 02:15.p.m. in forced convection at 02:15.p.m. The COP of refrigerator during forced convection was received 1.2 times more than that of during free convection and in case of heat pump during forced convection it was received 1.1 times more than that of free convection.
