If it is a shared ventilation, it is a house type adjacent to the kitchen and bathroom, which can be installed with a one-way damper, so that only the exhaust of the bathroom or kitchen is discharged into the air duct, so that the smoke or odor does not diffuse into your own house. If the wall is leaking, you need to look it up and find some foam materials or other suitable methods to plug it.

This is due to the wind outside.
According to aerodynamics, the flowing air pressure is small, and the aircraft can fly into the sky by relying on the lift generated by the wing of the aircraft, and the air flows to the leading edge of the wing, which is divided into two streams, upper and lower, which flow along the upper and lower surfaces of the wing respectively, and rejoin at the trailing edge of the wing and flow backward. The upper surface of the wing is relatively convex and the flow tube is thinner, indicating that the flow rate is increased and the pressure is reduced. On the lower surface of the wing, the air flow is blocked, the flow tube becomes thicker, the flow velocity slows down, and the pressure increases. >>>More

The exhaust port of the kitchen range hood is reserved and fixed, but the vents of the kitchen water heater and bathroom exhaust fan are generally not reserved.
