Danfoss Scroll Compressor Q&A

Q: What is a scroll compressor working principle?

A: The scroll compressor consists of two spiral-shaped scrolls, one of which remains stationary while the other orbits around it. As the orbiting scroll moves, it forms multiple crescent-shaped pockets between itself and the stationary scroll. Refrigerant gas is drawn into these pockets, where it is compressed as the pockets change shape and diminish in size until the gas is released.

Q: What is the difference between a scroll and piston compressor?

A: A scroll compressor works by the continuous movement of two scrolls. On the other hand, piston compressors work by having a motor-driven rod move back and forth within a cylinder. While both methods can compress gas, the piston method introduces more noise and vibration because of the repeated jerking motion. Generally, scroll compressors tend to be smaller, lighter, quieter, and more efficient than piston compressors.

Q: What are some strengths of Danfoss scroll compressors?

A: Danfoss scroll compressors are resilient and capable of withstanding extreme loads. They operate quietly, providing peaceful living and working environments. Their lighter and more compact designs make them easier to install and use in various applications. Generally, Danfoss scroll compressors are more efficient than piston models. Finally, scroll compressors have fewer moving parts than other types of compressors, making them easier to maintain and clean.
