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.

A compressor and a refrigerating machine which enable an easy disposal of a lubricant, are friendly to the natural environment, and have simple configurations, are provided. The compressor which is used in a refrigerating machine including an evaporator and a condenser and adapted for compressing refrigerant gas evaporated in the evaporator to convey the compressed refrigerant gas to the condenser, includes: a motor; a housing having a compression chamber inside; a rotary member which has a rotating shaft and is rotated by a driving force of the motor so as to compress water vapor serving as the refrigerant gas in the compression chamber; a bearing for supporting the rotating shaft of the rotary member in the housing; and a lubricant supplier for supplying water serving as a lubricant to the bearing.

Compressor and refrigerating machine

In the condenser provided with two of the degassing chambers separated by a cooling fluid, communication between the degassing chambers is prevented even if a pressure difference is increased between the degassing chambers. The condenser has the housing having the vapor inflow port connectable to the discharge portion of the compressor, the first degassing chamber, in the housing, communicating with the vapor inflow port, and the second degassing chamber, in the housing, arranged above the first degassing chamber across the partition portion, and the passing portion for permitting a cooling fluid to flow from the second degassing chamber to the first degassing chamber, wherein the first degassing chamber is separated from the second degassing chamber by the cooling fluid in the passing portion, and the passing portion has a pressure head space for containing a specified volume of cooling fluid so as to absorb a variation in a pressure difference between the first degassing chamber and the second degassing chamber.
