我把冷气打开，让房间凉快起来。

I turned on the air conditioner to cool down the room.

一旦你打开冰箱门，所有的冷空气都会被放出，当你再次关闭的时候，风扇把更多的冷空气引入冷气室，其制冷速度要比其它类型的设计更迅速。

Once you open the door, and all the cold air drops out, when you close it again, the fan directs more cold air into the cabinet lot quicker than it does on the other types of designs.
