Humidity Control Application


In damp or humid indoor un-conditioned environments such as basements, cellars, and garages, separate dehumidifier equipment can deliver many benefits. For intensely humid air-conditioned environments such as locker rooms and showers, a dehumidifier assists the air conditioning system with its work. Dehumidifiers work by pulling indoor air across warm and cool coils that contain refrigerant. As the air passes over, the moisture condenses and is collected in a container to be emptied.


On the opposite end of the scale, humidifiers are sometimes necessary for arid climates and also during cold weather when the furnace dries out the indoor air. A humidifier works by adding water vapor to the indoor air. Humidifiers accomplish this by one of the following four methods or variations/combinations of producing vapor from water.

Air-conditioning and heating equipment affect humidity

Before going into more detail on dehumidifiers and humidifiers, we should first list the roles air conditioning and heating equipment play in humidity control. In addition to cooling indoor air, the conditioning of air has to do with removing humidity. If an air conditioning system has too much cooling capacity, it cools too quickly and cycles on and off in short intervals. This does not allow enough time to "condition" the air by removing the humidity. This result in excessive moisture in the air—sometimes described as a "clammy" feeling. In contrast, a properly sized and working air conditioner will adjust the humidity during cooling cycles of optimum time.
