云南省某剧院空调通风设计

云南省某剧院采用直膨式全空气空调系统，空调系统由室外机直接蒸发式全空气处理机组两部分组成，无需水泵、冷却塔等设备，安装使用及维护方便。机组置于屋顶或者室外空地，无需机房，节省初投资，维修方便。机组不需要二次冷媒，系统效率高。剧院采用大风道，消声减震处理较为简单。介绍剧院直膨式空调系统、通风系统设计，包括空调冷热源、空调系统、防排烟系统、节能、自控、消声与隔振处理，直膨机与其他空调冷热源方案对比等内容。

Ventilating and Air-conditioning Design in a Theater in Yunnan Province

A direct expansion type air conditioning system is used in a theatre in Yunnan province, the entire system contains two parts including outdoor unit and a kind of direct evaporative all air handling unit. No water pumps and cooling tower equipments are used in the system leading to its convenience in installation and maintenance. Working units are placed in the roofs and outdoor space without any machine room, saving the initial investment and maintenance work. Units get high system efficiency with no need for a secondary refrigerant. Theatre uses large air ducts which silencing and vibration absorption processing are relatively simple. This paper gives an introduction on the designs of direct expansion type air conditioning system and ventilation system for the theatre, including cold and heat sources, air conditioning system, smoke control system, energy efficiency, automatic control, noise elimination and vibration isolation processing and also the comparison between direct expansion machines and other air conditioning schemes, etc.
