A great deal of waste heat is generated from the equipment room of subway station while heating demand exists in station platform, station hall, and office area. The conventional method is to use ventilation to remove the waste heat of the equipment room and use the heating system to meet the heat load of the corresponding heating area, which will cause a large amount of energy consumption and waste heat. The idea of using water-loop heat pump and multi-connected technology to recover waste heat from equipment room for heating of station is presented in this work. By analyzing the performance of the water-loop multi-connected heat pump system used in subway station, the preliminary design concept of the system is formed, the relevant mathematical model is established, and the optimal water temperature of the water loop is discussed. The simulation analyzes the operating characteristics of the system, and the variation law of auxiliary heating amount, heat recovery energy efficiency ratio, and overall energy efficiency ratio of the system are obtained. Based on this, this paper gives a prediction of the waste heat recovery potential of the subway stations in Harbin, Moscow, Montreal, and Helsinki.
