Taking The Vents Out Of Vented Crawl Spaces

Cooling load profiles for UFAD techniques and overhead techniques are different, primarily as a result of thermal storage effect of the lighter-weight raised floor panels compared to the heavier mass of a structural flooring slab. The mere presence of the raised floor reduces the power of the slab to retailer warmth, thereby producing for the system with a raised flooring higher peak cooling masses in comparison with the system and not using a raised flooring. In the OH system, notably in perimeter zones, a part of the incoming solar heat gain is saved within the ground slab through the day, thus reducing peak zone cooling masses, and launched at evening when the system is off. In a UFAD system, the presence of the raised flooring transforms the photo voltaic absorbing large ground slab right into a lighter weight materials, leading to relatively greater peak zone cooling loads. Ventilation in sub-ground areas can already be compromised by the build-up of particles within the flooring void and/or in and round vents, which once more presents dangers of condensation and associated issues.
