STEAM COMPRESSION TYPE REFRIGERATOR

摘要

PROBLEM TO BE SOLVED: To prevent the leakage of the refrigerant with a high pressure by holding an oil on the seal end surface of the rotary ring and fixed ring of a mechanical seal and prevent the performance drop by the increase of a slide loss by supplying the oil on a slider which is a slide part and the slide surface of a rod. SOLUTION: The refrigerant with lots of oil content is separated from the refrigerant with a few oil content by the oil separation mechanism 35 arranged on the entering side of a compressor 31 and the refrigerant with lots of oil content is supplied from a passage 7 to the seal end surface of the rotary ring 13 and fixed ring 12 of the mechanical seal installed on the shaft 14 and the oil is supplied from the passage 9 to the slider 10 which is a slide part and the slide surface of the rod 11.
