Energy-Saving Control Strategy Of Multi Air Conditioning Unit In The Building Automation System

The railway which has been appeared more than one hundred years now is booming, and the related structure of railway run is reasonably mature, but from the point of view of energy-saving, there are also some improvement measures, especially the subway station which has shield door.The optimized control for the multi-units of air condition system in the subway station is the important part of all devices manage in the subway Building Automation System (BAS) and which is distributed Multi-Agent System (MAS). Based on the analysis of environmental control system operation mode and the multi-objective optimization control theory, according to the actual demand of environment, the optimized set of data as a start is select dynamically and the frequency conversion unit control parameter set is installed. After rolling optimization, the optimal solutions parameter set is got, and achieves the purpose of energy-saving operation control.Use the Petri net to optimized the rationality which all kinds of power consumption equipments run or stop in the proper order, reduce the unnecessary consummation and then based on the result of the optimal multi-units run lead the parameters of people density,temperature and humidity, air enthalpy into the run of air conditioning unit, the various change as like the condition season, the suitable season, the small new wind season and the all new wind, which can simulate the reality circumstance, and verify the implementation and reliability, so the research of this test can provide some help for study of subway station in the future.
