What factors contribute to targeted air changes per hour (ACH)?

Targeted air changes per hour (ACH) are crucial for effective drying and restoration because they directly influence how quickly moisture is removed from the air in a given space. The volume of the space is important, as it determines how much air must be moved to achieve the desired level of humidity reduction. Different building materials can absorb moisture at varying rates and should also be taken into consideration, as this affects how air circulation needs to be optimized for effective drying.

Moreover, existing HVAC conditions play a vital role in the overall air movement strategy. An efficient HVAC system can facilitate better air circulation, enhancing the drying process by quickly replacing moist air with drier air. Therefore, understanding the interplay between the volume and the specific building materials, along with recognizing the capabilities and limitations of the HVAC system, enables a targeted approach to achieving the desired ACH for effective moisture removal and restoration.
