The purpose of a filter dryer in a refrigeration system is to:

Absorb moisture and contaminants
Cool the refrigerant
Increase the refrigerant pressure
Reduce noise

The correct answer is: Absorb moisture and contaminants

A filter dryer is a component in a refrigeration system that helps remove moisture and contaminants from the refrigerant. These contaminants can include dirt, debris, and acid, which can cause damage to the system if not removed. By absorbing these substances, the filter dryer helps to keep the refrigerant clean and prevent any potential damage. The other options are incorrect because they do not pertain to the specific function of a filter dryer. B is incorrect because a separate component, the condenser, is responsible for cooling the refrigerant. C is incorrect because a compressor is responsible for increasing the refrigerant pressure. D is incorrect because reducing noise is not a primary function of a filter dryer.
