Humidity control is an important aspect of maintaining oc-cupant comfort and providing satisfactory air quality. In sub-tropical climates such as Florida, maintaining acceptable humidity levels is far more challenging than other parts of the US. Many of us have had the unfortunate opportunity of experiencing high humidity conditions in a building. It starts with occupants seeing signs of mildew, sticky papers, condensation at diffusers and a cold, clammy, uncomfortable feeling of mugginess, and often smells associated with dampness. Over the years we’ve learned the intricacies of humidity loads and how incorrect HVAC equipment selection could result in additional costs, customer complaints, and even lawsuits due to high humidity.
I’d like to share with you some of the basics regarding understanding humidity loads and selecting equipment properly.
