Which of the following is not a type of compressor?

• A. Reciprocating
• B. Rotary
• C. Lateral
• D. Centrifugal

Answer: (C)

Compressors are categorized by how they compress refrigerant. Reciprocating compressors use pistons in cylinders to compress the gas. Rotary compressors rely on rotating elements, like screws or vanes, to trap and push the refrigerant. Centrifugal compressors use a high-speed impeller to add kinetic energy and then convert it to pressure. Lateral doesn’t describe a compression mechanism or design; it’s related to direction or orientation, not a type of compressor. So it isn’t a recognized compressor type.
