What defines a desiccant in HVAC systems?

A desiccant in HVAC systems is defined as a substance that can absorb moisture. Desiccants are materials that have a high affinity for water vapor, which allows them to remove humidity from the air in various applications, including HVAC systems. This moisture-absorbing property helps to control humidity levels, improve comfort, and enhance the efficiency of heating and cooling systems.

By reducing excess moisture, desiccants not only help prevent mold growth and structural damage but also contribute to better air quality and energy efficiency. Their ability to absorb and retain moisture makes them particularly valuable in dehumidification processes and in controlling humidity in spaces where moisture is a concern. Understanding the role of desiccants is crucial for professionals in the HVAC field, as it allows for the effective management of indoor climates.
