eli5: how do dehumidifiers make water from air?
In: 0
It doesn’t make the water, it’s already in there. It’s like a sopping wet towel. If the air is dry, the dehumidifier won’t pull any water out of it.
Remember that heat is energy. Air with energy can carry things along with it. Think of a garden hose turned up high and pushing a lot of leaves and dirt. If the air cools down, it loses that energy, and it drops what it is carrying. This is similar to a hose being turned down to a trickle and it can’t push dirt. The dehumidifier cools the air, it drops the water it is carrying into a basin, and blows the dry air out.
