A filter dryer designed for use in the _______ has a solid core of desiccant.

A filter dryer designed for use in the _______ has a solid core of desiccant.

• A. Liquid line
• B. Suction line
• C. Discharge line
• D. Gas line

Answer: (A)

Moisture removal in a refrigeration system must be tailored to where the filter-drier sits. In the liquid line, the refrigerant is a high‑pressure liquid heading toward the metering device, so the filter-drier needs to remove moisture reliably without shedding fines that could clog the throttle or cause damage downstream. A solid-core desiccant design provides a sturdy, compact core that stays in place under high-pressure liquid flow and won’t release particles into the system. That makes it the preferred choice for the liquid line filter-drier. In contrast, suction-line applications deal with vapor at lower pressures, where a different core configuration is more appropriate, so the solid-core design is not typically used there.
