在国外空气分布器(以下简称“风口”),七十年代已普遍成为厂家定型生产的系列产,并附有性能数据选用表或图,为设计部门的选用和施工部门的安装提供了很大方便;同时也促进了新型“风口”的发展,既满足了室内空气分布的要求,又美观大方,与建筑物相匹配,达到协调一致的效果。为统一评价其性能,美、英在七十年代初先后建立了此种产品的性能试验标准,1984年国际标准化组织在
In foreign air distributors (hereinafter referred to as “tuyere”), the 1970s have generally become a series of products for manufacturer’s stereotyped production, together with a performance data selection table or drawing, which provides great choice for the design department and installation of the construction department. Convenient; at the same time, it also promotes the development of the new “tuyere”, which not only satisfies the requirements of indoor air distribution, but also is aesthetically pleasing and matches the building to achieve a coordinated and consistent effect. In order to evaluate its performance in a unified manner, the United States and the United Kingdom successively established performance test standards for such products in the early 1970s. In 1984, the International Organization for Standardization
