In order to reduce the energy consumption of the subway condensation ventilation refrigeration air-conditioning system, the distributed parameter method and the sequential module method are used to study the mathematical modeling and solution of the subway air-conditioning system, obtain the operating parameters of the subway condensation air-conditioning system, and establish the energy consumption optimization model of the air-conditioning system in combination with the parameter analysis to achieve the automatic control optimization of the air-conditioning system under different working conditions. The simulation results show that compared with the original operation mode, the total energy consumption of the optimized air conditioning system is reduced by 8.7%-23.6%, which can effectively perform automatic regulation according to the actual operation conditions. The research analyzes the operation energy consumption of the subway condensing air conditioning system,and puts forward a low energy consumption operation optimization model, which has important practical value for reducing the operation energy consumption of the subway system and promoting building energy conservation.
