Analyzes the particularity of indoor environment requirement of subway station, summarizes the air conditioning load structure of subway station, and discusses the changing characteristics of air conditioning load. By analyzing the design status and actual operation status of air-conditioning system in subway station, the existing problems are pointed out and the reasons of subcooling in subway station are revealed. Combining with the engineering case analysis, a method to solve the problem of mismatch of equipment supply capacity and load demand of air-conditioning system and measures of energy-saving operation and management were put forward. Energy-saving potential of air-conditioning system in subway station was calculated.
