Desiccant Dehumidification – Wringing Excess Moisture Out of Indoor Air

Maintaining cooler temperatures, whether for comfort, cold storage, quality control of manufacturing processes or other cooling needs, is accomplished by regulating both the temperature (sensible cooling) and the humidity (latent cooling) of the indoor air.

A desiccant dehumidification system assumes responsibility for the humidity component of cooling—usually at least 30% of the total cooling load—allowing the cooling unit to be set for optimal temperature control and enabling the use of a smaller compressor and eliminating excess chiller capacity. Working together, conventional air conditioning and desiccant technology can
more efficiently handle temperature and humidity control, but desiccant dehumidification can be used as a stand-alone system.

The optimum relative humidity range (see chart) for health is considered to be in the 45% to 55% range.  Natural gas humidification and dehumidification systems can add moisture to indoor air during cold, dry winter months and wring excess moisture from hot, humid indoor air during the summer.
