Climatic chambers can control either the temperature or the humidity within them. This is a point that is sometimes difficult to understand, because the relative humidity (RH) percentage will depend on the existing temperature. The higher the temperature, the more moisture the air can hold.
Relative humidity is the ratio of the amount of moisture in the air to the amount it can hold. Changing the temperature changes the relative humidity, which makes temperature control very important, since stable temperatures ensure a stable humidity level.
The normal humidity range for test chambers is usually between 10% and 98% RH, ranging from 10°C to 90°C and limited by the dew point. Test chambers use the dew point to establish the relative humidity limit.
The best way to understand this theory is to look at the temperature vs. relative humidity diagram, which indicates the manufacturer’s humidity limits. It is important to work within these limits to prevent damage to the cooling system.
To achieve lower humidity levels, the chamber is usually equipped with an air-drying system to allow the coil to drop below freezing.
Climate testing regulations have well-defined temperature and humidity ranges. Please indicate the regulations you wish to follow so that DYCOMETAL can offer you the most comprehensive equipment in the humidity ranges you need to perform your tests. Since humidity depends on temperature, indicate the temperature points and the humidity at those points you wish to define so that we can properly define the humidification systems.
