What does "dehumidification" refer to in HVAC terminology?

In HVAC terminology, dehumidification refers specifically to the process of removing moisture from the air. This process is essential in controlling indoor humidity levels, which can improve comfort, enhance air quality, and prevent the growth of mold and mildew in buildings.

When dehumidification occurs, commonly through the use of air conditioning systems or dedicated dehumidifiers, it reduces the amount of water vapor present in the air, thereby lowering humidity levels. This is especially important in humid climates or environments where excess moisture can lead to discomfort and structural issues.

Maintaining appropriate humidity levels is crucial for both comfort and health, as high humidity can make temperatures feel warmer and can lead to various indoor air quality problems. Understanding dehumidification's role is vital for effective HVAC design and operation.
