Refrigerator with circulating lubricant system - has lubricant tank with heat exchanger ensuring temp. preventing foaming

摘要

The refrigerator has lubricant circulation system and the lubricant is transported from a storage chamber to the bearing. Refrigerant is dissolved in lubricant depending on the temperature. Foaming of the lubricant is prevented. The lubricant storage tank has in the region of inlet opening a heat exchanger which affects the temp of lubricant and refrigerant temp. This mixt. is brought to such a temp. that the refrigerant evaporates out of the lubricant and refrigerant mixture. The lubricant storage tank has permeable wall parts (6, 8) and the heat exchanger (7) encloses the inlet pipe (2) of the lubricant pump (1) in this area.
