What is the purpose of desiccants in refrigeration systems?

Desiccants are materials specifically used to absorb moisture from the air or refrigerants, which is critical in refrigeration systems. The primary purpose of including desiccants is to prevent moisture from entering the system, as water can lead to freeze-ups, reduce efficiency, and cause corrosion. Moisture can react with refrigerants, creating acids that may damage components and reduce the overall lifespan of the system.

By removing moisture, desiccants help maintain the integrity and efficiency of the refrigeration cycle, allowing it to operate smoothly and effectively. This function is especially important in systems where moisture can lead to operational failures or degradation over time.
