The air duct machine is a pipeline air conditioner, which is connected with the pipeline to supply air to the room; The so-called high static pressure air duct machine is a high static pressure fan used in pipeline air conditioning. The static pressure of air conditioner is equivalent to the residual pressure outside the machine, which is a parameter of air supply capacity of air conditioner. The greater the static pressure, the longer the gas supply lifting time. Because the duct air conditioner needs to pass through the duct, the wind pressure loss will increase during the air supply process. If you don't use a high static pressure fan, there will be little air sent into the room.

The installation needs a lot of work, so you just need to manage the air conditioner. As for the air duct pressure box, you can tell me the size of the iron sheet and make it for you. You can only do heat preservation. If it can be made of iron, it will be a piece of cake. Making an air duct machine may involve engineering, water, electricity and civil engineering. The real project is the detailed division of labor. Those who make water pipes only make water pipes, and those who make air pipes only make air pipes and hang ends. But some units are understaffed and do everything.
