S25 -- Mechanical Dehumidifiers and Related Components (I-P)

The correct moisture level in the air is important for health and comfort. Controlling humidity and condensation is important to prevent moisture damage and mold or mildew development, thus protecting buildings and occupants, and preserving building contents This chapter covers mechanical dehumidification using a cooling process only, including basic dehumidifier models (with moisture removal capacity of less than 3 lb/h [1.4 kg/h]) used for home basements and small storage areas, as well as larger sizes required for commercial applications. Requirements for testing and rating mechanical dehumidifiers’ energy efficiency are published in AHRI Standards 910 and 920.
