今天看到個公寓臥室裡牆上裝了一個這玩意，不知道是幹啥用的，是不是換氣的？

熱交換器

大哥，能具體點不，別只解釋字面的意思。咋交換？我看只有一個旋鈕開關，擰開之後就聽見嗡嗡的機器運作聲。是不是把屋裡的熱空氣換到外面，把外面的冷空氣換進來？

廢氣走，暖氣留。

廢氣走,暖氣留。

那就是冬天用的?把暖氣留下,冷的送走?還是廢氣排出?進新鮮的冷氣?

A heat exchanger is a piece of equipment built for efficient heat transfer from one medium to another. The media may be separated by a solid wall, so that they never mix, or they may be in direct contact.[1] They are widely used in space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, natural gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air.
