严寒地区IMAX影院放映机房空调系统优化设计

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。

Thermal Analysis of the Ground Properties with a Single Borehole Heat Exchanger

The effect of ground properties with heat conduction between soil and ground loop heat exchangers(GLHEs)has been analyzed.A finite line source model proposed by Cui,Yang,and Fang is used.Far field radius is defined.The analyses for a 1.5m borehole line source in three kinds of soil conditions:damp and breeze(D.B.),damp and heavy(D.H.),and saturated and heavy(S.H.)are carried out.The results of the comparisons show that in the condition of continuous operation,the variation of the far field radius is related to soil thermal conductivity.The rate of heat transfer will decrease after long time operation.And then soil condition will not influence the far field radius obviously.

严寒地区IMAX巨幕影院胶片放映机房空调系统优化设计

本文以项目工程‘辽宁科技馆’为例，介绍了北方严寒地区IMAX巨幕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，闲置时切换到一次回风工况。该文详细说明了计算选型、系统切换方法。本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。
