What mechanism do scroll compressors utilize to function?

• A. Rotating cylinders
• B. Reciprocating pistons
• C. Involute spirals
• D. Centrifugal force

Answer: (C)

Scroll compressors function using an innovative design involving involute spirals. The key mechanism consists of two spiral-shaped scrolls: one fixed and the other orbiting around it. As the orbiting scroll moves, it traps a volume of refrigerant between the two scrolls, effectively compressing it as the spirals continue to move closer together. This method of compression is highly efficient and produces a smooth, continuous flow of refrigerant, resulting in less vibration and a quieter operation compared to other compressor types. The use of involute spirals is fundamental to the operation of scroll compressors, as they allow for precise and efficient compression of the refrigerant gas. This design minimizes the mechanical wear associated with traditional piston-driven compressors and enhances the overall reliability of the system.
