What HVAC component is primarily involved in controlling humidity levels within a space?

The dehumidifier is specifically designed to control humidity levels within a space, making it the primary component for this purpose. It functions by removing moisture from the air, thereby decreasing the humidity level, which can improve comfort and prevent issues such as mold growth and condensation.

Dehumidifiers operate by drawing in humid air, passing it over cold coils to condense the moisture, and then releasing the drier air back into the environment. This capability is essential in areas where humidity can be detrimental to indoor air quality and overall comfort.

While chillers, heat exchangers, and fan coil units all have roles in HVAC systems, they primarily focus on heating and cooling rather than specifically managing humidity. Chilliers produce chilled water, heat exchangers facilitate heat transfer between fluids, and fan coil units circulate air for temperature regulation, but they do not target humidity control in the same way a dehumidifier does.
