What does "dehumidification" refer to in HVAC context?

In the context of HVAC, "dehumidification" specifically refers to the process of removing moisture from the air. This is crucial for maintaining comfort and indoor air quality in residential and light commercial spaces. High humidity levels can lead to a variety of issues, including mold growth, discomfort, and even structural damage. Dehumidification helps to reduce humidity to a comfortable level, typically between 30% and 50%, which not only enhances comfort but also protects building contents and improves air quality.

Removing moisture is typically achieved through various HVAC components, such as dehumidifiers or air conditioning systems, which cool the air to below its dew point, allowing moisture to condense and be drained away. Understanding this process is essential for HVAC professionals, as effective humidity control plays a key role in overall climate control and energy efficiency within a building.
