Abstract
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.
