A common design and installation practice for mechanical ventilation systems is to route the ducts along the slab. Ducts routed in this way supply fresh air to and extract stale air from 楼层 located below. This article describes in detail how to optimally implement such an arrangement in the program.
The 通风输配系统 for the upper 楼层 as 在下方楼板之上 - in this case the default distance of the axis of ventilation elements will be measured from the lower slab, 2. 通风输配系统 for the upper 楼层.
The values of ΔH通风, 顶送 (顶面送风口与吊顶的默认距离) and ΔH通风, 顶回 (顶面回风口与吊顶的默认距离) taking into account the value of the 吊顶厚度 for the 楼层 where 顶面送风口 / 顶面回风口 elements are located;
In the 2D编辑器 window:
Place 顶面送风口 / 顶面回风口 elements on the lower 楼层 (watch the video below),
Copy 顶面送风口 / 顶面回风口 elements to the 楼层 above with the use of the 将本层选中部件复制到上一层 function - in this case the duplicates of the 顶面送风口 / 顶面回风口 elements on the higher 楼层 will be used to connect the ventilation installation;
Insert the manifolds and connect the terminals with ducts, insert the remaining installation elements and continue working on the project according to the article Designing mechanical ventilation installations.
Delete the 顶面送风口 / 顶面回风口 elements on the 楼层 below;
To export / print the plan view of the lower 楼层 with visible 顶面送风口 / 顶面回风口 elements:
In the 打印 range, select 插入页面布局. ,
In the 打印楼层范围 field, select the storey on which the installation distribution is located and the storey on which the 通风末端 have been inserted,
In the 其它楼层的部件图层 field, deselect all branches, and in the 通风 branch, select 顶面送风口 and 顶面回风口. 3. 其它楼层的部件图层. 更多信息，见： Export / print results and drawings.
