JIS射流诱导系统已于本世纪90年代初期在欧美各国广泛得以应用,当前方正开始逐步应用于国内大型通风工程中,以此节约工程土建费用和经常运行费用,对特殊环境或空间能发挥出较传统通风系统更佳效果。本文就JIS的理论基础、设计要点及其应用特性、JIS与常规通风系统技术经济比较、JIS系统的设备配置和规格以及JIS测试方法等方面作一介绍,由此提出在大空间地下工程中逐步以射流诱导系统代替常规通风系统的可能性和优越性,供设计人员参考。
The JIS jet guidance system has been widely used in Europe and the United States in the early 1990s. At present, Founder is gradually applying it to domestic large-scale ventilation projects to save engineering civil engineering costs and recurring operating costs, and it can be used for special environments or spaces. Traditional ventilation system has better results. This article presents the theoretical basis, design essentials and application characteristics of JIS, the technical and economical comparison of JIS and conventional ventilation systems, the equipment configuration and specifications of JIS system, and the JIS testing methods, and proposes gradual progress in large space underground projects. The possibility and superiority of the jet-inducing system to replace the conventional ventilation system are available for designers’ reference.
