The peltier effect dictates that when you pass a current through two joined conductors it will take heat from one side, thus creating a cold face and transfer it to the other side, creating a hot surface.

Oh, and lets not forget they don’t exactly contain the most environmentally friendly substance and would have to be disposed of after being used. Estimation of dehumidifying performance of solid polymer electrolytic dehumidifier for practical application". Some dehumidifier models can tie into plumbing drains or use a built-in water pump to empty themselves as they collect moisture. Dehumidifiers are designed to pass air directly over the cooling coils and then the heating coils in a single efficient pass through the device.

If the condensate from the cooling coils is drained away from the room as it drips off the cooling coils, the result will be room air that is drier but slightly warmer. Energy Star Qualified Dehumidifiers Archived 2010-12-19 at the Wayback Machine table listing removal rates and efficiencies. If the area of use is not larger than 20 m², smaller models are suitable with a capacity of around 10 litres per day. The SPE consists of a proton-conductive solid polymer electrolyte and porous electrodes with a catalytic layer composed of noble metal particles.

Such integration can improve performance by improving the vapor compression cycle's COP (by operating between closer temperatures), [12] and enhancing air mixing near the membrane.In these circumstances it’s relative humidity you should concern yourself with and not absolute, as that will have little to no bearing. For example, if the humidity rises to 65% or higher in a living room, mould growth is much more likely. A desiccant dehumidifier draws air into the machine before passing it over a desiccant chemical to absorb the moisture from the air. Example 2 maintains a constant water content within the air while the temperature decreases, thus increasing the RH level. When the height of the air handler (containing the evaporator) is above the level of the surface drains used for rainwater, the condensate drain lines can often be routed into them.
