严寒地区IMAX影院放映机房空调系统优化设计

Air-conditioning System Optimal Design for an IMAX Projection Room in Cold Region

以项目工程‘辽宁科技馆’为例,介绍了北方严寒地区IMAX影院的胶片放映机房空调设计。该机房采用全空气空调系统,露点送风方式。放映机房工作时采用直流运行模式,准备阶段切换到一次回风工况。详细说明了计算选型、系统切换方法。系统在直流模式运行下利用了观众厅的排风作为放映机房的部分送风,在使用必要的空气过滤措施之后,也能达到较好的空调环境要求。

The sample project for this analysis is ＇Liaoning science and Technology Museum＇. In this project, the air-conditioning system design for an IMAX-film project room in cold region is written up. All-air system is used. Direct air-co.nditioning system is used in working time and primary return air system is for part time. Details are focused on the design calculation and switching between the two systems. When in direct system mode, part of the air supply is extracted from the auditorium. Required surrounding environment can be reached with proper filtration measures taken.
