Problems solved by technology

[0013] In the above-mentioned third method, adding heat pipes using copper with a high unit price will bring high cost
In addition, adding heat pipes will also reduce the thermal conductivity along with the decrease of the flow rate of cold water in the pipes, so there is no fundamental solution to the problem

Embodiment Construction

[0036] Below, refer to Figure 1 to Figure 7 Embodiments of the evaporator of the present invention and a turbo refrigerator equipped with the evaporator will be described. Figure 1 to Figure 7 In , the same reference numerals are assigned to the same or corresponding constituent elements, and overlapping descriptions are omitted.

[0037] figure 1 It is a schematic diagram showing one embodiment of a turbo refrigerator. Such as figure 1 As shown, the turbo refrigerator has: a turbo compressor 1, which compresses the refrigerant; a condenser 2, which uses cooling water (cooling fluid) to cool and condense the compressed refrigerant gas; an evaporator 3, It takes heat from the cold water (fluid to be cooled) to evaporate the refrigerant to exert cooling effect;

[0038]The turbo compressor 1, the condenser 2, the economizer 4, and the evaporator 3 are connected by refrigerant piping 5A, 5B, 5C, and 5D through which refrigerant circulates. More specifically, the turbo co...

Abstract

The invention provides an evaporator of a turbine refrigerator and a turbine refrigerator having the evaporator at a low cost, and the evaporator can improve heat conductivity. The evaporator has a heat conduction tube (35) in which a cooled fluid flows, and a gas-liquid separator (41) which is configured in a tank body (31) and separates refrigerant gas from refrigerant liquid. The gas-liquid separator (41) has a flow path unit (42) in which a gas-liquid refrigerant flow path (45) is formed, and a refrigerant gas guiding component (50) connected with the flow path unit (42). A refrigerant gas flow path (51) communicated with the gas-liquid refrigerant flow path (45) is formed inside the refrigerant gas guiding component (50), and extends upwards along an inner surface of the tank body (31).

Description

technical field [0001] The present invention relates to an evaporator of a turbo refrigerator, and more particularly to an evaporator that takes heat from a fluid to be cooled such as cold water, and evaporates a refrigerant to exert a cooling effect. Furthermore, the present invention relates to a turbo refrigerator including such an evaporator. Background technique [0002] Conventionally, turbo refrigerators used in refrigerating and air-conditioning equipment and the like are constituted by a closed system in which a refrigerant is sealed, and are constituted by an evaporator that absorbs heat from cold water (fluid to be cooled) to evaporate the refrigerant to exert a cooling effect, a compressor for compressing the refrigerant gas evaporated by the evaporator into a high-pressure refrigerant gas; a condenser for cooling the high-pressure refrigerant gas with cooling water (cooling fluid) to condense it; An expansion valve (expansion mechanism) that depressurizes and e...
