How do dehumidifiers work and how do they collect so much water in a seemingly dry room

In: Technology

Answer 1

Ever notice how a cold drink cup sweats? That is dehumidifying the air by having water condense on a cold surface. A dehumidifier works like an air conditioner, but instead of pumping heat outdoors, it cools air to collect water on the evaporator and then heats it up again by running it over the condenser. The evaporator drips water into a collection bucket.

The evaporator gets cold because refrigerant liquid is allowed to expand and in doing so it absorbs heat. It then goes to a compressor and a condenser where it becomes liquid again and in doing so gives off heat.
