Question

Do we get oxygen when the room is closed and ac is operating?​

Answer 1

Yes. Because the air of the room is taken out through the ac and fresh air is taken from the outside by the ac, cooling is done and then circulated throughout the room. The air contains oxygen.

Answer 2

Answer:

YES

Explanation:

• In a closed room, an air conditioner will recirculate the oxygen and nitrogen already present
• However, there are always openings and crevices in a room that allow oxygen to be replaced and air to circulate through doors or windows.
• Unless a space is explicitly intended to keep air out, oxygen will always find its way in.
• Even a negative flow room or isolation room in a hospital will have enough oxygen to circulate.
• Professional air conditioning not only recycles air, but also refreshes it by introducing some (conditioned) fresh air.
