Research Status of Heat Recovery Device in a Train Station of Severe Cold Area

This paper investigates the characteristics of heat production and quantity of heat production of personnel flow in the train station of Shenyang city. It overviews the energy-saving method for waste heat recovery from the exhaust vent. In this article, the advantages and disadvantages of various heat recovery devices are listed. Comparing the applicability and efficiency of these heat recovery devices by the numerical calculation method, the way of recovering exhaust heat by heat pipe and heat pump combined heat recovery unit is more efficient and energy-saving. Heat pipe exchanger has high heat efficiency and can avoid cross contamination effectively. The combination of the heat pipe exchanger and the heat pump ensure the efficiency of heat transfer while improving operational reliability. This provides theoretical and experimental basis for the future research.
