Dehumidifier Corporation of America (DCA) designs dehumidification systems for a wide range of applications. We have provided dehumidification solutions to hotel and motel chains, homeowners and manufacturing facilities where the control of relative humidity is critical. No matter what kind of building you operate, summer humidity can pose a real problem. High humidity is a particular threat for facilities that store sensitive items that can be ruined by moisture, like food or powdered products that take on moisture.
What is Humidity?
Humidity can be measured as both relative and absolute. Absolute humidity refers to the mass of water vapor divided by the dry air mass, within a volume of air at a known temperature (see HowStuffWorks for more information). As the temperature of the air rises, the potential of water content increases.
Humidity is most-often measured in relative terms. Relative humidity is the ratio of the absolute humidity to the highest possible absolute humidity. A 100% relative humidity signifies total saturation, leading to the formation of rain droplets. People are most comfortable at a relative humidity 40-60%: any higher and natures air conditioner will slow down sweat from evaporating at an efficient rate and therefore the air will feel hotter to the body than it actually is.
Why is Humidity Harmful?
In addition to discomfort, humidity can also lead to structural problems, causing mold and mildew growth. Excess moisture can rot wood framing, which reduces structural integrity and provides a breeding ground for mold and pests. This is dangerous for occupant health because mold and mildew are known to cause respiratory problems, allergic reaction symptoms, nervous-system disorders and even depression.
Limitations of Air Conditioners When Combatting Humidity
A.C. systems effectively cool indoor spaces and remove some moisture, but they also raise the relative humidity indoors. This often results in mold and mildew accumulation in air moving duct work, which results in poor indoor air quality and “sick building syndrome”. ASHRAE standards now stipulate that all buildings must dehumidify outdoor air before sending it to the HVAC system.
