Refrigerator

摘要

The refrigerator includes: a cooling-water line having a cooling-water pump to thereby send water for cooling a refrigerant inside of a condenser; a lubricating-water supply line connecting the part downstream from the cooling-water pump on the cooling-water line and a compressor 4 and supplying water flowing through the cooling-water line as a lubricant to the compressor 4; and a backup portion supplying water to the lubricating-water supply line instead of supplying water from the cooling-water line when the cooling-water pump is not driven.

主权项

1. A refrigerator, comprising:
a compressor including a compression portion, a rotating shaft attached to the compression portion, and a bearing axially supporting the rotating shaft, for compressing water vapor as a refrigerant by the rotating of the rotating shaft; a condenser for condensing a refrigerant compressed by the compressor; an evaporator for evaporating a liquid refrigerant condensed by the condenser; a cooling-water line including a cooling-water pump to thereby send water for cooling a refrigerant in the condenser; a lubricating-water supply line supplying water from the cooling-water line to the compressor as a lubricant for the bearing of the compressor, the lubricating-water supply line connecting a part downstream from the cooling-water pump on the cooling-water line and the compressor; and a backup portion for supplying water to the lubricating-water supply line instead of supplying water from the cooling-water line when the cooling-water pump is not driven; wherein the backup portion includes an emergency lubricating-water supply line for supplying water in the evaporator to the lubricating-water supply line.
