What is the primary function of a dehumidifier in an HVAC system?

The primary function of a dehumidifier in an HVAC system is to remove moisture from the air. High humidity levels can lead to discomfort, mold growth, and damage to furnishings and building structures. By extracting excess moisture from the air, a dehumidifier helps to maintain optimal humidity levels, which promotes a more comfortable indoor environment and improves overall air quality. In addition, reducing humidity can enhance the efficiency of air conditioning systems, as they do not have to work as hard to maintain cool temperatures when excess moisture is eliminated. This function is particularly crucial in climates where humidity levels can be persistently high.
