Discussion on the design of air conditioning system for station management rooms in northern metro
LI Yong-bin
Abstract：Based on the characteristics of subway station management rooms,a comprehensive comparison is made among three types of air conditioning systems:all air primary return air conditioning system,fan coil unit air conditioning system,and multi split air conditioning system.Research has shown that the all air primary return air conditioning system,as the preferred solution for conventional subway station air conditioning systems,has advantages such as low initial investment and good matching between control strategies and external environment.However,its operating costs are high,control is complex,and it has a significant impact on civil engineering;The fan coil unit air conditioning system is suitable for office spaces,but its piping is more complex compared to the other two types of air conditioning systems,and there are more potential water leakage hazards;The multi split air conditioning system has the advantages of low operating costs,good heating effect in winter,simple control,and stable and reliable system,so it is recommended as a priority solution.
