What is the function of the desiccant within the A/C system?

The primary function of the desiccant within an A/C system is to absorb moisture. In air conditioning systems, especially those with moisture-sensitive components, maintaining the correct humidity level is crucial for efficient operation and to prevent issues like corrosion or freezing. The desiccant material acts as a drying agent, drawing in and holding excess moisture from the refrigerant and the air, which helps maintain optimal performance and prevents the formation of ice in the evaporator coil. Keeping moisture levels low also enhances the longevity of the system by protecting internal components from damage caused by excessive humidity. Other components, such as filters and blowers, serve different roles, but the desiccant's unique function focuses solely on moisture control.
