What is the main purpose of dehumidifiers in an AC system?

The main purpose of dehumidifiers in an air conditioning system is to remove moisture from the air. High humidity levels can lead to discomfort, promote mold growth, and affect air quality. By removing excess moisture, dehumidifiers help maintain a comfortable indoor environment while also improving the efficiency of the air conditioning system. When humidity is controlled, the cooling system doesn't have to work as hard to lower the temperature, resulting in improved energy efficiency and performance.

While cooling the air, circulating air, and heating the space are functions that can be part of an air conditioning system, they do not address the primary goal of dehumidifiers, which is to specifically reduce humidity levels in the air.
