The reduction in energy reserves in recent years has made waste heat recovery an important technical means to solve energy shortages. As an important part of campus service facilities, university baths have the characteristics of large residual heat, dense population and high energy consumption. Through field research on several college baths, we can grasp the general energy loss of existing college baths. Starting from the analysis of bathing wastewater, exhaust gas emission and energy loss in the discharge path, combined with sewage source heat exchanger, dual-source heat pump and phase-change water tank, the research on the design of a waste heat recovery system suitable for university baths in severe cold areas is carried out. Using fluent software the system’s total residual heat, water temperature, flow and other parameters in the system are mastered, and finally the formula to derive the system energy utilization is used. The sewage source heat pump, the wastewater–exhaust gas dual-source heat pump and the phase-change water tank are coupled with each other to carry out step recovery of the waste heat of the bath, which provides a new idea for the utilization of waste heat of the auxiliary service of the public institution.
