What type of compressor uses impellers to draw in vapor?

The type of compressor that uses impellers to draw in vapor is the centrifugal compressor. This specific design utilizes a rotating element, known as an impeller, which spins at high speeds to impart kinetic energy to the gas or vapor being compressed. As the impeller rotates, it accelerates the vapor outward from the center to the edges, converting kinetic energy into pressure energy as the vapor exits the impeller.

Centrifugal compressors are typically employed in applications where a large flow of gas is required, and they operate efficiently at high speeds. This makes them particularly suitable for use in industrial processes, refrigeration, and HVAC systems. The reliance on impellers allows for a smooth and continuous flow of vapor, distinguishing them further from other compressor types, such as reciprocating or screw compressors, which operate based on different mechanical principles.
