Don't close the ventilation shaft in the kitchen on the 15th floor, and don't close the smoke exhaust.
-
The ventilation shaft of the kitchen on the 15th floor should not be sealed, and it is best to have smoke exhaust in the kitchen, but the ventilation shaft. Don't go crazy!

Of course not.
This is wind pressure balanced.
It also has the effect of exhaust.
Sealing it will cause an anomaly.
Theoretically, no.
To consider the cross-section of the smoke duct, in my opinion, the design of 2400 * 750 smoke well duct should be 1800 * 600or 2000*550, so it is not feasible to change to 1700*750. >>>More
Resolutely not, because the fume well is responsible for all the fume removal functions of your unit and the same house. If the sprinkler pipe passes through it: first of all, it will bring infinite oil smoke to your home; Secondly, the oil smoke will accumulate on the spray pipe, and the spray pipe will become thicker and thicker, and the oil smoke is flammable, and a fire will occur when the conditions are ripe! >>>More
If you are on the ground floor, you can smash the part below the vent that retains itself, but be sure to do a good enough blocking. If you're not at the bottom, don't smash it. Otherwise, the resident kitchen below will not be able to exhaust and will always find you.
The well should be re-drilled from the outside, otherwise, the sand in the well will move out with the water, and there is a danger of collapse in the future, which will threaten the safety of the house.
Uh-huh, this should be fine.
Otherwise, you don't pretend to try it, if you really feel that you don't install it, the smoke is scattered, then it's not too late to install it, and you are not afraid of damaging the ground tiles if you install that kind of hanging rail. >>>More
