Which drying system involves the intentional use of outdoor air?

Open drying is a method that intentionally incorporates outdoor air to expedite the drying process. This technique allows environmental air to help in the evaporation of moisture from wet materials and surfaces, taking advantage of natural ventilation. Utilizing outdoor air can be very effective, particularly in conditions where the external humidity levels are lower than that of the indoor environment, as it promotes better drying efficiency.

This method is particularly beneficial in large spaces or during favorable weather conditions where the external air can significantly aid in lowering humidity levels indoors and facilitating moisture removal from the affected areas. Open drying systems typically ensure a continuous airflow which helps in reducing indoor humidity while enhancing drying times.

The effectiveness of this technique can vary depending on outdoor conditions such as temperature and humidity, making it crucial to assess these factors before relying solely on open drying.
