movement of fresh air indoors
The way fresh air moves into and through a room or building, often using a fan or special system, so the air does not become hot or dirty.
用法模式：
ventilation in [a place] / ventilation of [a building or room]
常见错误：
Learners sometimes confuse "ventilation" with "air conditioning." Ventilation means moving and replacing air (fresh air in, stale air out), while air conditioning usually means cooling and sometimes drying the air, but not always bringing in fresh air from outside.
近义词
air circulation (Stresses the general movement of air, without especially focusing on the system that provides it.)
反义词
stagnant air (Describes air that does not move and is often dirty or unpleasant, which ventilation is meant to prevent.)
