摘　　要：基于高大洁净装配厂房工程实例,对室内工艺环境需求进行分析,选定合理的换气次数及气流组织,提出了分层洁净空调系统设计方案,并针对工程实际应用特点,在分层洁净空调系统中引入了通过室内外静压差控制的定送变回系统。工程实测结果表明,与传统空调系统设计相比,定送变回分层空调系统不仅能够根据房间内外静压差快速调节空调系统的新风量和回风量,保证高大空间的温湿度、洁净度及压差控制要求,而且可以降低运维管理难度及空调运行能耗。Based on a engineering example of large space clean facility,the requirements of indoor process environment were analyzed,reasonable air exchange rate and air distribution were selected,then proposes the stratified cleaning air conditioning system design scheme.According to the practical application characteristics of the project,variable return air volume system controlled by indoor and outdoor static pressure difference was introduced into the stratified cleaning air conditioning system.The engineering test results show that,compared with the traditional air conditioning system,the variable return air volume of stratified air conditionging system could not only quickly adjust the fresh air rate and return air rate of the air conditioning system which based on the static pressure difference inside and outside the room,that ensured the temperature,humidity,cleanliness and pressure difference control requirements of large space,but also reduce the difficulty of operation and maintenance management,and save the energy consumption of air conditioning.
