你有图示显示风对室内压力的影响吗?

如果风是从南方吹来的,那么家里的正压力是如何产生的呢?

Unfortunately we don’t have any diagrams to clearly depict the effects ofwind pressure on a home. Were you looking for a diagram for your own understanding or for educational purposes in a presentation? It’s a great question, and there are many variables at play so I will try to lay them out clearly.
A wind from the south will create a positive pressure on the south facing wall, forcing air through any holes in your building envelope. That will create positive air pressure inside the house, and force air out other holes in your building envelope.
A vacuum won’t be created inside the house, butsort ofoutside the house, on the north. That south wind will create a negative pressure outside of your north wall, so more than just being an issue of increased air pressure inside the house, wind will create a negative pressure on the opposite side of a home and draw air from that wall.
家里的空气压力也会受到任何机械排气的影响,比如中央真空吸尘器、灶台罩、浴室风扇等。暖空气上升的自然叠加效应将在房屋中产生对流,并在建筑围护结构的顶部产生正压力。风对你的舒适度和效率的影响程度取决于你的房子的密闭性。致以最亲切的问候。
