Comprehensive evaluation of HVAC system control techniques in the railway stations based on analytic hierarchy process

Based on the study of HVAC system control technical characteristics and analysis of existing control techniques in the railway stations, proposes typical evaluation indexes and evaluates comprehensively the control techniques combined with analytic hierarchy process (AHP) according to the HVAC system design and operation experience. Puts forward the control technology applicability zoning for different building climate and station scale, which offers technical supports for the control system and is favourable to carry out optimal operation of the railway station HVAC system.
