Embodiment Construction

[0018] refer to Figure 1 to Figure 4 One embodiment of the turbo compressor and refrigerator according to the present invention will be described.

[0019] The turbo refrigerator (refrigerator) 1 according to this embodiment is installed in a building or a factory in order to generate, for example, cooling water for an air conditioner, such as figure 1 As shown, it is provided with a condenser 2 , an economizer 3 , an evaporator 5 and a turbo compressor 6 .

[0020] The condenser 2 is supplied with compressed refrigerant gas X1 that is a refrigerant (fluid) such as R134a compressed in a gaseous state, and cools and liquefies the compressed refrigerant gas X1 to become a refrigerant liquid X2. The condenser 2 as figure 1 As shown, the turbo compressor 6 is connected to the flow path R1 through which the compressed refrigerant gas X1 flows. In addition, the condenser 2 is connected to the economizer 3 via a flow path R2 through which the refrigerant liquid X2 flows. In the ...

Abstract

The invention provides a turbo compressor and a refrigerator. The turbo compressor includes an impeller; compression stages having scroll chambers which introduce the refrigerant to the impeller or lead the refrigerant compressed by the rotation of the impeller to the outside; and an oil tank in which a heater is disposed and an lubricant oil is stored, and at least a part of the scroll chambers is disposed in the vicinity of the oil tank.

Description

[0001] This application claims priority to Japanese Patent Application No. 2009-170191 for which it applied on July 21, 2009, and uses the content here. technical field [0002] The invention relates to a turbo compressor and a refrigerator. More specifically, it relates to a turbo compressor capable of compressing a fluid through a plurality of impellers, and a refrigerator including the turbo compressor. Background technique [0003] As a refrigerator that cools or freezes a cooling object such as water, a turbo refrigerator including a turbo compressor that compresses and discharges a refrigerant by a compression mechanism including an impeller or the like is known. In a compressor, as the compression ratio increases, the discharge temperature of the compressor increases and the volumetric efficiency decreases. Therefore, in a turbo compressor including a turbo refrigerator as described above, the refrigerant may be compressed in a plurality of stages (for example, refer...
