How does an air conditioning system assist in moisture control?

An air conditioning system assists in moisture control primarily by cooling the air and removing excess moisture. When air conditioning is in operation, it cools the warm air that passes over the evaporator coils. As the air cools, its ability to hold moisture decreases, leading to condensation. This condensation collects in a drainage system, thereby removing excess humidity from the air.

This process not only helps to lower the temperature but also significantly reduces humidity levels, creating a more comfortable indoor environment. Controlling moisture is crucial because high humidity levels can lead to issues such as mold growth, musty odors, and can affect the overall comfort and health of occupants.

Heating the air or merely circulating it without any change in temperature does not address humidity control effectively. Similarly, increasing humidity levels contradicts the goal of moisture control within an air conditioning context.
