Regarding the control room, the cabinet room is designed to be at positive pressure – how many companies do this?

In the control room and cabinet room, the design institute originally planned for a positive pressure system, but several of my colleagues said they had never seen such a setup before. Dear sea friends, have you ever seen such an example?
There are many, cabinets used in the oil and petrochemical industries; I’ve seen quite a few that are pressure-resistant and explosion-proof. It’s a hazardous environment, so it’s necessary to prevent flammable gases from entering the box.

Positive pressure explosion protection is used in hazardous explosive environments, while control rooms are generally considered safe areas where there are no explosive gases or dusts. Is it a waste to use positive pressure explosion protection in such cases? Moreover, control rooms are usually places where people come in and out; how can a positive pressure environment be created there? What size air supply pipes would be required?
Slight positive pressure. I’m using slight positive pressure; there’s too much dust outside, so it’s not possible to supply some instrument air:L
The design was done and the installation was completed, but it’s just for show – it’s only used when Americans come for inspections. :Lol, they go to such lengths to save energy – look how creative the Chinese people are. sea
But there are people coming in and out of the control room, which is hard to control
I think so too; several of my colleagues in the control room have never seen positive pressure
Bro Pig is really professional, but it seems unnecessary to do this in my environment
How is your instrument air distributed into the rooms?
I’m curious about how the air is introduced into the room – it can’t just be through a single point, right?:shutup:
For the non-explosion-proof instrument analysis booths and frequency converters on site, we have positive pressure ventilation in place. Some control rooms are equipped with a purified air supply line to prevent unpleasant odors from entering them.
