Which component is described as being constructed of brazed cylinders with baffle plates mounted inside?

• A. Condenser
• B. Mufflers
• C. Receiver drier
• D. Filters

Answer: (B)

Mufflers in refrigerant systems are designed to quiet the flow by creating multiple passageways and absorbing energy. They’re often built from brazed copper cylinders with baffle plates mounted inside to form a compact, multi-chamber path. As the refrigerant moves through the stacked cylinders and past the baffles, sound waves are broken up and dissipated, which lowers noise levels. That construction description specifically fits a muffler.

A condenser is a heat exchanger that rejects heat and condenses refrigerant; it’s not built as a stack of brazed cylinders with internal baffles. A receiver drier is a desiccant-filled vessel used to remove moisture, not a multi-chamber baffle arrangement. Filters are simple housings with filter media, without internal baffle stacks.
