Research on energy saving control of ventilation and air conditioning system of underground railway station in Wuhan region

Considering the load characteristics, summarizes the current situation and deficiency in underground railway station air conditioning systems, and performs by using an intelligent fuzzy control method the optimization of integrative control from the aspects of air system, water system, and group control of refrigerating machines for Wuhan Line Forth underground railway stations.  The economical analysis results show that the initial investment of the intelligent fuzzy control system can be recovered within three years.
