In a drying system that uses both outdoor air and mechanical dehumidification, what is this system called?

The term "combination drying" accurately describes a drying system that utilizes both outdoor air and mechanical dehumidification. This approach leverages the benefits of both methods to enhance the efficiency of the drying process.

In a combination drying system, outdoor air can be brought in to help lower the relative humidity levels and to facilitate evaporation, while mechanical dehumidifiers work to further remove moisture from the air. This synergy allows for effective moisture removal from building materials and structures, leading to a faster drying process.

Utilizing both strategies in tandem can optimize the drying environment, ensuring better control of humidity and reducing the overall drying time compared to either method used in isolation. This technique is particularly valuable in water damage restoration scenarios, where time and efficiency are critical to preventing secondary damage and mold growth.
