摘　　要：对变风量空调系统(VAV)的产生与组成进行了介绍,并对VAV空调系统中定静压控制的原理进行了简单的描述。针对风量平衡问题,主要对最不利点的选择、VAV-BOX连接一次风管长度、VAV-BOX连接二次风管长度、送回风静压值、静压值的设定这5个影响因素进行分析和研究,最后对各影响因素提出了相应的整改措施。This paper introduces the production of VAV air-conditioning system and the system composition. It also briefly describes the principle of static pressure control in the system. Specific to the air volume balance, this paper elaborates and analyzes 5 impact factors including the selection of the most unfavorable point, the length of VAV- BOX primary air-pipe, the length of VAV-BOX secondary air-pipe, the static pressure value of supply and return air, and the setting of static pressure value. Finally, the corresponding rectification measures are proposed for all impact factors.
