Which type of compressor relies on the principle of centrifugal force?

The centrifugal compressor operates using the principle of centrifugal force. This type of compressor is designed to move air or gas by converting the kinetic energy generated by the rotation of an impeller into pressure energy. The impeller spins at a high speed, causing the gas to be flung outward away from the center, hence the term "centrifugal." As the gas moves outward, its speed increases, and a diffuser converts that high kinetic energy into pressure, allowing for efficient air compression.

In contrast, scroll compressors, rotary compressors, and reciprocating compressors utilize different mechanical principles for operation. Scroll compressors involve two spiral-shaped scrolls that compress the refrigerant through orbital motion. Rotary compressors use rotating elements to compress gas, often featuring vanes or rollers. Reciprocating compressors operate by using a piston that moves in and out of a cylinder to compress the gas. Each of these types has specific applications and benefits, but none rely on centrifugal force, which is unique to centrifugal compressors.
