Analysis and determination of the thermal parameters in the waste heat recovery system based on heat pump

There are large quantities of waste-heat produced in the machining process of cartridge type structures(58SiMn steel), it is necessary to recycle and make full use of these heat from the perspective of environmental protection and energy saving. We will study the possibility of using the recalled calories to privide bath water for workers and the compensate water for steam boilers. In this paper the waste heat recovery system that based on heating pump were analyzed, including the system composition, working principle, the thermal parameters, etc. According to the technique characteristics of hot pump and making use of thermodynamics mechanism we carried on analysis and calculation about the lost thermal energy in the medium repeatedly heat machine, the power of medium repeatedly. We can make 17.33 ton hot water which is 55 Celsius degree per hour using the recalled calories. These hot water can provide the nedding water for the steam boilers and the workers bathing. This research show that waste heat recovery system which is used in the production of the cartridge type structures is effectual.
