Dehumidification Process

Relative humidity is the measure of of the partial pressure of water in its gaseous state in an air and water mixture to the saturated vapor pressure of water at a given temperature. This is expressed as a percentage. Most people are used to the television meteorologist stating the humidity level, such as 70 percent humidity during the summer or a 20 percent moisture level on a cold winter day. What matters to most people is the comfort level, which is often rated on a scale such as the humidex or heat index. When it comes to the weather, people want to know what it "feels like" when they step outside.

Normal humidity levels in homes and work places are controlled in part by the heating, ventilation and air conditioning system. The ideal relative humidity level for human comfort is around 40 to 50 percent, although this is somewhat temperature dependent. People are highly sensitive to the amount of water vapor in the air, as it is the process of evaporation of moisture from the skin, also known as perspiration, that allows humans to cool off when hot. People will feel warmer when the water vapor level in the air is higher compared to when it is lower even as the temperature remains constant.

Dehumidifiers work by using energy to draw moisture out of the air. Small dehumidification systems use a reservoir to collect the water, which the user must then dump out before it overflows and either automatically shuts down or creates a hazard. In larger dehumidifiers, the moisture is drained away through a hose or pipe that is connected to the waste water system. Some units have both drainage options available for the user to select one or the other. The system consists of several parts, including the fan compressor, reheater, compressor cooling coils and water collection area. Most will also have a humidistat that allows for customized control of the humidity level. The humidistat measures the electrical resistance caused by water vapor between two pieces of metal, allowing the unit to turn on and off as needed.

Dehumidifiers for your basement and dehumidifiers for the home are available in two types, including stand alone models for small basements and built-in dehumidification systems that work in conjunction with the air conditioning and heating system.

When You Should Use Dehumidifiers

A dehumidifier should be used in the home or in a building any time when the air feels muggy or condensation develops on the windows. Other times when using a dehumidification system will be useful include:

• When mold growth is present or suspected.
• After water has infiltrated the home or building, such as after a flood or burst water pipe.
• When the air conditioning system is not properly working.
• When exhaust fans or other ventilation equipment are not able to perform adequately.
• While washing and drying clothing.
• When cooking or doing other household activities that generates water vapor.
• While using a shower or dishwasher that generates steam.
