Abstract: The design methodologies for reducing operational problems in a hermetically sealed single-cylinder R-12 compressor used in deep freezers are discussed. Excessive oil throw was reduced to acceptable limits by modifying the suction pipe location in the shell, intake muffler orientation, oil hole dimensions and improved cooling of shell exterior. For eliminating connecting rod end wear, bronze sleeves were introduced in the bearing along with changes in journal hardness. Accelerated life tests were conducted on modified and production compressors to demonstrate the effectiveness of the modifications.
