Muffler system for refrigeration compressor

摘要

A hermetic reciprocating piston refrigeration compressor has a high efficiency muffler system. The suction muffler has an inlet adjacent the refrigerant return line and is made of an insulating material. It is mounted on a pair of suction tubes secured to the cylinder head and extending into the interior of the muffler. A discharge muffler system includes a pair of large muffler chambers formed partially in a cylinder block and connected by an external transfer tube. A large straight passage connects the discharge plenum in the cylinder head with one muffler chamber, while a discharge line extends from the other muffler chamber to the exterior of the compressor casing.
