Semco LLC has launched the Unitary Wheel Cassette (UWC) Series, a sensible and latent energy recovery aluminum desiccant wheel. The company claims the UWC Series is designed and packaged as the HVAC industry's first drop-in replacement for polymer desiccant wheels in most unitary ERV brands.
When the time comes to replace or install energy recovery wheels in commercial HVAC units, engineers may have to deal with several installation challenges including limited access areas, bulky components, and complex assemblies.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
