What is rotary compressor?
Rotary. The rotary compressor can be divided into two types. One has blades or vanes that rotate with the shaft. The other type has the blade which remains stationary and is part of the compressor housing assembly. In both types, the vapor from the suction line is drawn into the cylinder through the suction port.
How does a compressor move vapor?
Vapor from the suction line is moved through the intake valve as the piston move downward. As the piston moves upward, it compresses the vapor refrigerant which is then pushed through the exhaust valve into the condenser. The compressor may has more than one cylinder which is also known as multicylinder compressor.
How does a reciprocating compressor work?
