Can the kitchen range hood exhaust pipe be directly discharged from the outside through a hole in th

It is also possible that the smoke exhaust pipe of the range hood is larger than the hole in the exterior wall.

The wall hole is large, the flue resistance is small, and the smoke exhaust effect is good. The wall hole is small, the flue resistance is large, if it is too small, it will affect the smoke exhaust.

If the flue is blocked, the resistance is the greatest, and the smoke cannot be exhausted.

The main wall you are talking about is actually a load-bearing wall, and the load-bearing wall of a building cannot be changed in any way, especially not to arbitrarily punch through the wall holes, even if it is a hole for air conditioning installation, it is also necessary to consider its correct position, the diameter of the smoke pipe of the exhaust fan is larger than the air conditioning pipe, and it is wrong to hit the upstairs of your house, which not only destroys the structure of the house, but also destroys the earthquake resistance of the house, and if you hit it from top to bottom, in the event of an earthquake in the future, it will collapse from the place where the structure is damaged.
