Which type of compressor typically provides quieter operation?

• A. Scroll compressor
• B. Rotary compressor
• C. Reciprocating compressor
• D. Centrifugal compressor

Answer: (A)

Scroll compressors are known for their quieter operation compared to other types of compressors. This is primarily due to their design, where two spiral-shaped scrolls compress the refrigerant continuously without the back-and-forth motion found in reciprocating compressors. The smooth, continuous compression process produces less vibration and noise, making scroll compressors ideal for applications where sound levels are a concern, such as in residential air conditioning systems. In contrast, rotary compressors, while also quiet compared to reciprocating ones, still produce more noise than scroll compressors because they rely on rotating elements. Reciprocating compressors, known for their robust design, create more vibrations and noise due to the piston motion involved in the compression process. Centrifugal compressors can be efficient and quieter at large scales, but for residential or smaller applications, scroll compressors remain the superior choice in terms of noise reduction.
