How a dehumidifier is a small fridge for air
It cools air past the dew point, catches the water, then warms the air again.
When the purchase is complete, return to the original window. It will refresh.
From the opening
A dehumidifier is a small refrigeration machine aimed at the moisture in room air. It cools air until vapor condenses on a cold coil, catches that water, and usually warms the air again before blowing it back into the room. The opening covers a cold coil below the dew point, why the room air comes back warm, and the bucket is condensed vapor.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
