REFRIGERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent shortage of lubricating oil from occurring in any of a plurality of compressors installed parallelly in a single refrigerant circuit. SOLUTION: A refrigeration device is provided with an oil balance pipe 10 from a high pressure section H of the compressor 1 to a refrigerant suction pipe 5 connected with the compressor 2 and an oil balance pipe 12 from a high pressure section H of the compressor 2 to a refrigerant suction pipe 4 connected with the compressor 1. A capillary tube 11 is installed in a halfway position of the oil balance tube 10 and a capillary tube 13 is installed in a halfway position of the oil balance tube 12.
