Why do sesame bedroom doors open under the door? 3

I know I want air to flow inside me, but why are the bedroom doors airy? I have visited many malls and there is ventilation in the bedroom door. Then why

They are probably used as return valves for people with central heating and air conditioning.

When you have radiators and ventilation in every room. The air must be able to get out of the room, as fresh air enters the room through the ventilation holes for the exhaust air of the central heating / air conditioning system. Otherwise, the heating / cooling system will not work.

When the door is closed, no air can escape from the room. In this case, the heating / cooling system does not provide much air conditioning to the room. Therefore, when the door is closed, air can flow through these ventilation holes and fresh air can enter the room through the room heating / AC ventilation holes and replace the old air. Exit this vent to return to central heating / air conditioning. ..

I am going to check the seals around the windows and vents to make sure that air is coming in. If the airflow in your room does not match the others, I suggest contacting your HVAC company to check the ventilation (which I think you should do every year). If it is sealant, it may be necessary to bend the window. You can easily check your windows and windows to see if the outside air is coming out. My bedroom windows allow more outside air circulation than other bedrooms, LOL. I just put an extra blanket on my bed (I like it cool so it's okay with me).

Gas heating It is also a legal safety requirement for built-in bricks (one brick / ventilation).
