Energy saving control system design and test data analysis of air conditioning water system in an underground railway station

Presents the energy saving control system design of air conditioning water system for an underground railway station in detail. Considering the characteristics and difficulties of air conditioning water system control in the underground railway station and combining with many technologies of load forecasting, fuzzy control, frequency conversion and others, conducts the energy saving control on air conditioning water system and equipment with the target of optimal COP of air conditioning water system. Adopts a mode control method to realize the linkage control and coordinated operation of air system and water system. According to the test data of fifteen cooling stations, the comprehensive energy saving rate of the energy saving control system at all stations is more than 25%, which verifies the effectiveness of energy saving control system of the water system.
