Dehumidifiers utilize a heat pump (similar to an air conditioner's heat pump) or perhaps chemical substance adsorbents to get rid of moisture out of the atmosphere without cooling the air.

A heat pump dehumidifier uses a lover to draw interior air over a heat exchange coil. The coil is just about freezing. The water in the air flow condenses on the coil and arctos portable ac energy consumption [www.vashonbeachcomber.com] it is drained. A next heat exchange coil reheats the air, that the dehumidifier exhausts into the space.

A heat pump dehumidifier dumps heat lost out of the compressor as well as fan motors into the air. It comes back to the indoor air the heat generated by the dehumidifier turning water vapour to fluid.

Chemical adsorbent dehumidifiers
This particular sort of dehumidifier is created for warm, humid climates and isn't really suited to be used in Canada.
Synthetic adsorbent dehumidifiers take up moisture from the air with a "desiccant"--a drying agent like silica gel. The desiccant is holding a heat exchange wheel. A separate air loop dries the wheel and exhausts the hot, damp air out of doors through special ducting.

A substance adsorbent dehumidifier uses more power compared to a heat pump dehumidifier. It is only cost-effective when it utilizes natural gas for heat exchange--and next just if natural gas is available at a low summer fee.
