解决进排风短路方式的探讨

Discussion on Solving Short Circuit Mode of Air Inlet and Exhaust

为保证机械防烟系统的安全可靠、新风系统的清洁卫生,本文采用常规的风管构件组合并加以改进,创造出一种解决进排风短路的低阻力防风防雨的排风(排烟)装置。该装置结构简单、制作安装方便、造价低、几乎不需要维护检修、具有较高的技术经济价值。

In order to ensure the safety and reliability of the mechanical smoke control system and the cleanness and hygiene of the fresh air system, this paper uses the conventional air duct component combination and improves it, and creates a low resistance, windproof and rain resistant exhaust(smoke exhaust) device to solve the short circuit of the air inlet and exhaust. The device has the advantages of simple structure, convenient manufacture and installation, low cost,almost no maintenance, and high technical and economic value.
