If the design of the air-conditioning system of the high-current equipment management room of the subway station lacks reliable equipment calorific parameters,it is not conducive to the optimal design of the subway air-conditioning system and energy saving and emission reduction.This paper proposes a method for calorific calculation and analysis of air conditioning equipment in the management room of subway station strong current equipment,and applies it to four subway stations in Zhengzhou area,and studies the influence of indoor air temperature,subway operation,equipment rated power and station type on the heat generation of subway strong current equipment management room equipment.The results show that although the indoor air temperature has a great influence on the external surface temperature of the equipment,it has little influence on the heat flux density and heat generation of the equipment.The heat generated by the equipment during the operation of the subway is greater than that generated by the equipment during the non-operating period,and the heat generated by the equipment is lower than the rated power of the equipment.
