Desiccants are used in

Explanation:
Desiccants absorb moisture, which is dangerous in refrigerant circuits because water can cause acid formation, corrosion, and ice blockage at the expansion device. To protect the system, moisture is removed by a device that incorporates desiccant—the drier (often a filter-drier) in the refrigerant line. That’s why desiccants are used in driers. Filters mainly remove particulates, coils are heat exchangers, and compressors don’t remove moisture, so those options aren’t the right fit.
