Research on the variable static pressure control used iterative algorithm in a VAV system Hongmei Jiang1,2,a ,Qingchang Ren1,b ，Yan Bai1,c 1School of Civil Engineering, Xi'an University of Architecture and Technology, xi’an 710055,China 2College of Electrical and Information Engineering, Lanzhou University of Technology, Lanzhou,730050,China ajhmxmsh@sina.com brenqch@163.com ccoffeetreecn@126.com Keywords: VAV system; Iteration algorithm; Variable static pressure; Control; Energy-saving Abstract: In a VAV system the static pressure can be reseted based on the change of load.
The basic principle of this method is: static pressure would always be minimum under the most unfavorable terminal,try to maintain the VAV terminal air valve opening at 75% ~ 95% (this range can change according to actual engineering) of full open state in each of the VAV terminal.
