In many different applications, there is a need to maintain a specific temperature and humidity range. The most obvious of these applications is in commercial greenhouses where different types of plants from actual vegetable or fruit production to the growth of medical marijuana requires specific temperatures and humidity at different times in the life cycle of the plants.
There is also the need for specific temperature control in aging of wood used in furniture and cabinetry as well as for paper production and the production of specific types of textiles. Wine is also stored to age are specific temperatures and humidity levels and these need to be consistent and not stray outside of a limited range.
The Dual Nature of Humidity and Temperature
For these types of systems, production and storage facilities, using a dual temperature and humidity controller makes sense. This is because of the relationship between the two factors.
Humidity levels, what is known as relative humidity, is dependent on temperature. The warmer the temperature, the more water vapor that can remain in the air. As air heats up, it can hold more water vapor, so the higher temperature equates to higher humidity. Dew or condensation occurs when the air cools off and cannot hold the water vapor possible when it was warmer, resulting in moisture on the surface of items in the environment.
By using a dual temperature and humidity controller that allows for specific parameters for both measurements, it is easy for a facility to maintain the right conditions though the same control.
This eliminates deviations or differences that can occur when trying to integrate a separate temperature and humidity control system that may have different levels of sensitivity and accuracy.
With the use of a programmable temperature and humidity controller it is possible to automatically adjust for daytime and nighttime variations, for differences in zones or growing seasons and to coordinate the two factors for the needs of the plant or the product during the life cycle or production cycle.
