Which device is used to reduce noise in refrigeration equipment and may be located on the compressor intake and exhaust?

• A. Valves
• B. Fans
• C. Mufflers
• D. Compressors

Answer: (C)

The key idea is using a sound-attenuating device to quiet refrigeration equipment. Mufflers are designed specifically to dampen noise from systems like compressors by providing an acoustic path that absorbs or dissipates sound energy as air flows through. Placing them on the compressor intake and exhaust helps reduce the noise radiated by the compressor and the connected piping, making the equipment quieter in the surrounding area. Valves control refrigerant flow and pressure, not noise reduction. Fans move air for cooling and can create noise themselves, but they aren’t meant to reduce noise in the system. Compressors generate much of the noise, so a muffler is the appropriate device to address that noise directly.
