This paper presents the optimized control principle of the variable air volume(VAV)air conditioning system from four aspects,including the VAV terminal unit control,the supply air temperature control of the air handling unit(AHU),the fan speed control of the AHU,and the outdoor air volume control of the air conditioning system.Each aspect is clarified in terms of what each control action should do and how to do it well in terms of control targets,control objects,and control logic.
