Reciprocating Compressors
Reciprocating compressors use pistons driven by a crankshaft to compress refrigerant vapor. They have distinct suction and discharge valves that open and close with each stroke. These compressors are common in medium to large commercial refrigeration systems. Common failure modes include broken valve plates (causing loss of compression), worn piston rings (causing blow-by), and bearing failure from oil starvation. They produce more vibration than scroll types and require solid mounting.
Reciprocating compressors use pistons and valve plates. Common failures: broken valves, worn rings, bearing failure.
