Energy Star 50-pint Dehumidifier

There is misinformation floated in some of the comments. Hopefully this will clear up most of it. As an engineer type, I do more of the detail thing but hey, whatever floats your boat.

NOTE: Although I own this model, this is mostly information on dehumidifiers in general. Other reviewers offer detailed specifics so no duplication needed here.

This covers 1-how it works; 2-sizing tips; 3-general tips, 4-cautions and user reflections.

HOW DEHUMIDIFIRES WORK

 
First, a dehumidifier is just like an air conditioner except for the location of the warm coil [technically the condenser coil]. With an A/C system the warm coil is outside the house [needs a 2nd fan], so an A/C unit has its cooling coil [technically a DX or expansion coil] inside the house [cooling it] and the heat it absorbs from the house air is transferred to the warm coil outside the house. Basically it is simple; the heat in the house is dumped outside. It's gotta go somewhere!

With a dehumidifier, the warm coil is inside, so the air cooled by the cooling coil blows across the warm coil [one fan needed]. Why? What happens? Well the cool air passing through the cool coil is warmed by the warm coil before exiting the unit.. The net result is that air discharged from the dehumidifier leaves the unit at about 100F [or about 20F warmer than room temperature]. What happens is that a dehumidifier does a better job removing moisture from the air but does not cool the house.

If you are a little confused, try this. Turn your dehumidifier off for about 5 minutes [this is important, trust me]. When you turn it on, put your hand immediately over the discharge air from the unit. You will feel cold air. As the warm air coil heats up, the discharge air changes from cold air to warm air.
