根据冷空气下沉、热空气上升的物理原理,所以我们要把空调出风口方向朝上吹.怎么翻译成英文啊?

..........
According to the physical principle shows that the movement of the cold air moves down and the hot air rises , therefore we need to adjust the direction of the output blower up to blow.
翻译的不太对呢 特别是出风口这个专业名词不会。。。。见谅了

According to the rules of physics, hot air goes up and cold air goes down. Therefore, the outlet of the air conditioning should be facing up.
