Thermoelectric dehumidifiers use a Peltier heat pump to cool a surface and condense water vapor from the air. The design is simpler and has the benefit of being quieter compared to a dehumidifier with a mechanical compressor. However, because of its relatively poor Coefficient of Performance, this design is mainly used for small dehumidifiers ...
As the water clings to the desiccant, the desiccant "bed" becomes saturated. When the media in the first tank becomes saturated, the air stream is automatically redirected through the second tank. The first tank is then heated while a portion of the dried air, referred to as the purge air, is back flowed through the tank and vented to atmosphere.
At the same time, the fan is slowed to reduce the evaporator temperature and condense more water. A dehumidifier uses the same refrigeration cycle but incorporates both the evaporator and the condenser into the same air path; the air first passes over the evaporator coil, where it is cooled [52] and dehumidified before passing over the ...
The water makes soapy bubbles when agitated. Before I realized all this I did water my plants with the water and the skewed pH caused nutrient lockout and sick plants. I eventually traced the problem back to the dehumidifier water. Keith — Preceding unsigned comment added by Keith 69 (talk • contribs) 08:21, 9 July 2014 (UTC)
DOAS Diagram. Moisture Removal Efficiency (MRE) is a measure of the energy efficiency of any dehumidification process. Moisture removal efficiency is the water vapor removed from air at a defined inlet air temperature and humidity, divided by the total energy consumed by the dehumidification equipment during the same time period, including all fan and pump energy needed to move air and fluids ...
Humidistats are used in a number of devices including dehumidifiers, humidifiers, and microwave ovens.In humidifiers and dehumidifiers, the humidistat is used where constant relative humidity conditions need to be maintained such as a refrigerator, greenhouse, or climate-controlled warehouse. [2]

Once steam is used it turns to hot water or condensate. This pump and possibly many more around the plant returns this hot water back to a make-up tank closer to the boiler, where it can be reclaimed, chemically treated, and reused, in the boiler, consequently it can sometimes be referred to as a condensate return pump.
