Moisture in the air passing over it freezes. It defrosts and wallah water 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Diligent_Nature Added an answer on July 13, 2019 at 8:08 pm 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. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp TheJeeronian Added an answer on July 13, 2019 at 8:05 pm I’m gonna blow your mind here: Gases can dissolve liquids. Air dissolves a little bit of water into it, which is another way of looking at evaporation. This dissolved water cannot stay dissolved if the air gets cold enough, and when this happens the water forms droplets. This is how rain forms, as well. Now, in a dehumidifier, air is sucked in, cooled down, the water droplets are collected, and then the air is pushed back out. On the way out, the cold air warms up while inside of the machine, and ultimately the room actually gets slightly warmer. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse What is the capital of UK?
