Research On HVAC System Design Of Metro Command And Control Center

In the rapid development of our country city background,with the development of urban rail transit project,command and control center of the HVAC system in the process of operation,often cold source selection is not reasonable,which leads to energy waste,air conditioning can not guarantee precision electronic equipment for temperature and humidity at electronic information room,dispatching the hall does not meet the comfort requirements of office process equipment technology and personnel etc..Therefore,the research of HVAC system of the Metro command and control center has become an important topic in the urban rail transit project,which has attracted more and more attention and attention.This article mainly aims at the metro command and control center,inside the building with complex functions,characteristics of various demands,both electronic information room,and office personnel and training room,and room for dispatching hall in large space,and the cold and heat source of HVAC system,air conditioning system for electronic information room in various forms,characteristics of scheduling the process requires complex.According to these three aspects,combined with the previous project problems and experience,using the analytic hierarchy process(AHP method)were studied methods of cold and heat sources;air conditioning system for electronic information rooms,combined with the closed cold channel,the corresponding Computational Fluid Dynamics(CFD)analysis,on the airflow simulation systems are analyzed;the design form of air conditioning system on the dispatching hall,with personnel and equipment and special requirements for the design of large screen analysis and research.This paper analyzes and studies the three aspects of the subway command and control center which are different from the general civil comprehensive architecture and the design requirements and key points of the subway station.The project should be in the cold and heat source selection process,increase the use of the scope of analytic hierarchy process analysis;using closed cold channel and send return air room precision air conditioning system,in the form of electronic information in the computer room;dispatching hall should be taken into account in the equipment and personnel on t he basis of environmental requirements,with variable air volume the air conditioning system and air conditioning system was split zoned small,and set up 2~3 system for mutual standby.
