What is the starting point for sizing desiccant dehumidification in larger commercial drying applications?

In larger commercial drying applications, the starting point for sizing desiccant dehumidification is to focus on the target air changes per hour. This parameter is crucial because it directly relates to how many times the air in a given space needs to be replaced to effectively reduce humidity levels and achieve the desired drying conditions. By determining the necessary air changes per hour, professionals can calculate the volume of air that needs to be treated and thereby establish the size and capacity of the dehumidification equipment required.

This approach ensures that the dehumidification system is adequately equipped to handle the volume and moisture load present in the area being dried. It is essential for creating a balanced drying environment that optimizes the effectiveness of the desiccant process. The other options, while related to drying, serve as factors that influence the overall drying strategy but do not serve as the primary basis for sizing desiccant dehumidifiers.
