How to install fresh air system in a 2-meter-high chess room without ceiling?

1. For cabinets, you can put them directly in the chess room, introduce fresh air into the room through the air duct, and exhaust the dirty air. When installing, it is necessary to connect the air inlet and air outlet of the new fan to the outdoor and fresh air pipes respectively. If you choose the lifting fresh air system, you need to install a lifting bracket indoors first, and then install the fresh air system on the bracket.

2. The fresh air pipeline needs to introduce fresh air from the outdoor and transport it to the indoor through the pipeline. When arranging the pipeline, try to ensure the smooth flow of the pipeline and avoid elbows and narrow parts. Pipes can be arranged on the wall, ceiling or ground, and the specific location should be determined according to the indoor layout and decoration.

3. Connect the fresh air pipeline with the fresh air system to ensure that the joint is sealed. At the same time, the fresh air system needs to be connected with the smoke exhaust pipe to exhaust the indoor dirty air.
