How does a scroll compressor operate?

• A. By using a single piston to compress refrigerant
• B. With two compliant scrolls, one fixed and one oscillating
• C. Through centrifugal force to compress gases
• D. By circulating refrigerant through a series of coils

Answer: (B)

A scroll compressor operates through a unique mechanism involving two spiral-shaped components called scrolls. In this design, one scroll remains stationary while the other orbits around it. As the orbiting scroll moves, it creates pockets that trap refrigerant gas between the two scrolls. As these pockets move toward the center of the compressor, the space around the refrigerant gas becomes smaller, resulting in increased pressure.

This method of compressing refrigerant is efficient and provides smooth operation with low noise levels compared to other compression techniques. It effectively handles various refrigerants, making it suitable for various refrigeration and air conditioning applications. Understanding how these two compliant scrolls work together to compress the refrigerant is crucial for comprehending the overall efficiency and functionality of scroll compressors.
