Abstract：Taking urban underground integrated pipe gallery project as the research object,the numerical model of integrated chamber was established,and the influence of different inlet air temperature and humidity on the thermal and humid environment and energy-saving of air conditioning system was studied by using ANSYS Fluent software.At the same time,different dehumidification treatments were carried out on the supply air flow,and the influence of isothermal dehumidification and heating dehumidification on the high relative humidity area inside the pipe corridor was analyzed.The results show that the temperature and humidity of the same section at different heights are stratified under the action of mechanical ventilation,and the heat transfer effect decreases with the increase of the distance from the inlet,and the energy consumption is high.Under the same ventilation volume,the heating and dehumidifying method has better dehumidification effect and can realize energy saving.
