no
Fumes from the chemicals can not escape the room if the windows and doors are shut, and are at times toxic.
To properly ventilate a room with windows open and the air conditioning on, you should open windows on opposite sides of the room to create cross ventilation. This allows fresh air to come in and stale air to go out. The air conditioning helps to maintain a comfortable temperature while the fresh air circulates.
Yes, it is not efficient to have the air conditioning on while the windows are open because it can waste energy and increase electricity costs.
No, you should not open windows and doors during a tornado. This common myth suggests that it equalizes pressure, but it actually increases the risk of injury and allows debris to enter the building. Instead, seek shelter in a small, windowless interior room or basement, and stay away from windows and doors. Your safety is the priority during such severe weather.
Leaving a window open while using air conditioning is not recommended because it can let warm air in and reduce the efficiency of the cooling system. It is best to keep windows closed to maximize the effectiveness of the air conditioning.
When windows are open, it creates better air circulation in a room. This can equalize the air pressure inside and outside, making it easier for doors to close smoothly.
Closed! If you leave the windows open all the cool air will go out the windows, and your house won't get cool.
Through open windows, doors, etc.
it means you are leaving the doors and windows open
Normally, no. If you are using an actual air conditioner, open windows and doors simply allow for more air transfer to and from the outside, forcing the unit to run more, wasting energy. However, if you are using an evaporative cooling unit (otherwise known as a "swamp cooler"), you might be able to get more air to flow through the unit by having **some** (not ALL) other windows open. Evaporative coolers tend to put a lot of humidity into the air, which is fine in drier climates, but not so good in, say, the eastern half of the US.
Too many variables to answer this one accurately. Outside temperature, wind chill, general infiltration, other doors/windows open, efficiency of heating/air conditioning unit etc etc.
