REFRIGERATING PLANT

摘要

PURPOSE:To embody stable oiling without reducing refrigerating capacity when an oil separator is used. CONSTITUTION:In a scroll compressor for feeding oil to a sliding part by a difference between delivery pressure and the pressure of a back pressure chamber, oil separated by an oil separator is introduced to a rotation axis end through a feed 30. Sealing members 27, 28 are provided on an axis end surface for stable feed. This eliminates the overheating of an inlet gas to prevent a decrease in refrigerating capacity and to inhibit temperature rise. And a plurality of compressors can be operated by using one piping.
