Installation of refrigerant pipe in multi line system时间：2022-01-04浏览次数：506
The multi on-line system occupies relatively small installation space, which is conducive to the comprehensive improvement of the height of the pipeline network.
There are two kinds of pipelines in multi pipeline pipeline: refrigerant pipeline and condensate pipeline. Refrigerant pipes are divided into liquid pipes and air pipes. The size of copper pipe is relatively small, which is represented by lines on the construction drawing. As shown in the figure below, the two dimensions represent the dimensions of the gas pipe and the liquid pipe respectively. The larger one is the gas pipe and the smaller one is the liquid pipe.
The copper pipes entering the site are in bundles, and the on-site workers keep the copper pipes warm. Put the air pipe and liquid pipe together and wrap them with black tape.
The on-site refrigerant pipe is just a pipe, unlike a perfect circle or ellipse. Therefore, in the comprehensive modeling of pipes, 100 or 80 ° pipes can be used to represent cold pipes.
The degree of freedom of the refrigerant tube is also very high, which can be understood as software and can be bent.
The copper pipe is connected by welding. After welding, it is wrapped with insulation and tape.
The pipe clamp is a hanger when installed on site, and then the pipe clamp covers the hanger of the refrigeration medium channel.
After the copper pipe is installed, check the leakage when inflating the roof.
As for the opening of the condensate tube well, the site will not be as orderly as the construction drawing.
Directly open a square hole, hit it on the angle steel on the wall, and fix the refrigerant pipes on the angle steel one by one with clips.
There is no need to dwell on models.
In some BIM projects, the modeling accuracy is very high. For this kind of bifurcated pipe, the user-defined family is used to draw the gas pipe and liquid pipe separately, and the workload is huge.
If it is just to optimize the route of the drainage pipe and improve the clear height of the ceiling, there is no need to carry out similar calculations. Personally, I think it's enough to draw a 100 or 80 pipe to represent the refrigerant pipe.
