Conservation of energy is the important factor from global point of view. Waste heat recovery has become significantly necessary and instant effort should be made to conserve this waste energy. Presently the refrigerator system rejects a lot of heat through condenser. This heat can be used for a variety of useful purposes. A multiuse refrigeration setup has been developed in which, both heating and cooling will be done simultaneously with the help of single vapour compression refrigeration cycle. It has a waste heat recovery system from the compressor for heating effect. Here without disturbing refrigeration cycle, the waste heat energy is used for useful work. The study has shown that such a system is technically feasible and economically viable. This concept has a scope of applications in variety of products such as air conditioners, freezers, water coolers and small scale refrigeration plants. This project leads to hybrid heating and cooling application with same vapour compression refrigeration system

Existing refrigeration systems generally put the high temperature and pressure of refrigerant vapor into the atmosphere or cooling water through the condenser to reach the purpose of condensing refrigerant. But this will lead to the environment “thermal pollution”, and a waste of energy. This paper describes a plan of modification of the existing refrigeration system, through the waste heat recovery unit can be recovered the condensing heat effectively and product hot water in 50~ 60 to provide bathing. This system also can improve the refrigeration system operating conditions and the efficiency of generating units to achieve the purpose of energy saving.

In this paper, a heat pump water heating system with waste heat recovery in ammonia refrigeration system was put forward, based on the practical project analysis of energy demand and waste heat emission. Based on the operating characteristics of ammonia refrigeration system, the ammonia heat exchanger was designed to be installed in series on the ammonia main pipe, which can ensure the system operate efficiently and reliably. Through the analysis of measured data, significant economic benefits had been brought about by using the heat pump water heating system. This project can save 2.19 million RMB in annual operating cost, and the investment recovery period will be only 1.5 years. The heat pump water heating system has excellent development prospect.
