The condensing apparatusincludes: a compressorwhich has a compression partcompressing a working fluid; a condenserwhich condenses the working fluid compressed by the compression part; and a spray mechanismincluding a nozzlewhich sprays a cooling fluid into a fluid passageto cool the working fluid flowing through the fluid passagebetween a discharge opening CSof the compression partand an inletof the condenser

Condensing apparatus

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 compressorand supplying water flowing through the cooling-water line as a lubricant to the compressor; 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.

Refrigerator

An axial flow compressor includes: an electric motor including a rotating shaft; a compression portion including a driving shaft connected without a speed-up gear to the rotating shaft of the electric motor and a rotor rotating together with the driving shaft, the compression portion driving the driving shaft and thereby compressing a working fluid; and a velocity reducing portion having a space for reducing the flow velocity of a working fluid discharged from a discharge opening of the compression portion. The rotating shaft of the electric motor is connected to the end of the driving shaft on the side of the discharge opening; and the velocity reducing portion is disposed so as to surround the electric motor.

Axial flow compressor

An axial flow compressor includes: a rotor having a rotor vane; a first pressing member joined to one end surface of the rotor; a second pressing member joined to the other end surface of the rotor; a rotor shaft portion penetrating the first pressing member, the rotor and the second pressing member; and a nut which fixes the first pressing member and the second pressing member on the rotor shaft portion with the first pressing member and the second pressing member holding the rotor between. The rotor shaft portion is made of a material having a lower linear expansion coefficient than that of a material making at least a part of the rotor. The material making at least a part of the rotor may be aluminum or aluminum alloy.
