Abstract

The utility model discloses a liquid baffle plate structure of a flooded evaporator. The liquid baffle plate structure is characterized in that: a liquid baffle plate is arranged above a liquid free surface and below an air outlet in a flooded evaporator shell; and a gaseous cold medium flow port is reserved between the liquid baffle plate and the inner wall of the shell. A liquid cold medium is prevented from entering a compressor by the liquid baffle plate, so that a part of insufficiently-evaporated liquid refrigerating working medium is separated from a gaseous refrigerating working medium when the refrigerating working medium returns to the compressor, a part of liquid refrigerant is prevented from entering the compressor and causing a wet compression or cylinder impact accident, and an entire refrigerating cycle is stably completed by the refrigerating working medium. By adopting the liquid baffle plate structure, the influence of liquid impact on a refrigerating compressor is eliminated, and safe running of the refrigerating cycle is ensured.

Description

Flooded evaporator liquid barrier structure
Technical field
The utility model relates to the vapor-liquid separation structure of flooded evaporator, relates in particular to flooded evaporator liquid barrier structure.
Background technology
Full liquid evaporimeter heat exchange pattern is that heating wall is immersed in the boiling that is taken place in the liquid with Free Surface in the existing central air-conditioning full-liquid type water-cooled main frame, and the free buoyance lift of bubble energy of generation passes liquid free surface and enters upper space.General flooded evaporator all can leave 1/3~1/4 gaseous space, allow the liquid refrigeration working medium that is mixed in the gaseous state refrigeration working medium drip as far as possible, but the various still inevitable liquid refrigerants of, climatic environment with a vast territory because of China are inhaled into compressor, cause liquid hammer, damage compressor.
The utility model content
The purpose of this utility model is to provide a kind of flooded evaporator liquid barrier structure, and the liquid refrigeration working medium that part is not evaporated is fully separated with the gaseous state refrigeration working medium, avoids the operative liquid cold-producing medium to enter compressor.
Flooded evaporator liquid barrier structure of the present utility model is characterized in: in the flooded evaporator housing above the liquid free surface, below the gas outlet liquid barrier is set, leave the gaseous coolant communication port between liquid barrier and the inner walls.
Described flooded evaporator liquid barrier structure, its further characteristics are: liquid barrier and inner walls are partly welded, and leave attitude refrigerant communication port near the two ends at evaporator outlet place.
Described flooded evaporator liquid barrier structure, its further characteristics are: retaining fluid-tight plate is welded at the liquid barrier two ends in the described flooded evaporator housing respectively, liquid barrier and liquid barrier, inner walls are formed the semi-hermetic space, isolate liquid refrigerants and evaporator outlet.
Because liquid barrier has stopped that liquid refrigerants enters into compressor, in the time of can making refrigeration working medium return compressor, the liquid refrigeration working medium that part is not evaporated is fully separated with the gaseous state refrigeration working medium, avoid the operative liquid cold-producing medium to enter compressor, cause Wet Compression or towards the cylinder accident, refrigeration working medium is stablized finished whole kind of refrigeration cycle, the utility model has been eliminated the influence of liquid hammer to refrigeration compressor, guarantees the kind of refrigeration cycle safe operation.
Description of drawings
Fig. 1 is the fundamental diagram that the full liquid evaporimeter of liquid barrier is installed.
Fig. 2 is the shape schematic diagram of shrouding.
Fig. 3 is the shape schematic diagram after liquid barrier launches.
The specific embodiment
See figures.1.and.2, flooded evaporator liquid barrier structure comprises the cylindrical shell 3 of liquid barrier 1, shrouding 2, flooded evaporator, liquid barrier 1 and cylindrical shell 3 parts are welded to connect, shrouding 2 is welded to connect with liquid barrier 1, cylindrical shell 3 respectively, form an airtight relatively space, to isolate liquid refrigerants and evaporator outlet 5.The edge 22,23 of shrouding 2 welds with the end edge of liquid barrier 1 respectively, the edge 21 of shrouding 2 and cylinder inboard wall welding.
As shown in Figure 3, liquid barrier 1 forms 4 communication port 50 with cylindrical shell 3, and its concrete size W and L need to keep certain velocity of liquid assets according to the refrigerating capacity flow design.The height h that puts of liquid barrier 1 also is according to different evaporator designs, roughly is placed on 3/4 cylinder internal diameter place, fully isolates the refrigeration working medium of gas-liquid mixed.
Please refer to shown in Figure 1, the liquid refrigeration working medium of low-pressure low-temperature 6 enters flooded evaporator from entering the mouth, through heat exchanger tube 4 heat exchange efficiently, the free buoyance lift of bubble energy that produces, pass liquid free surface and enter upper space, gaseous refrigerant then enters the communication port 50 that liquid plate 1 and cylindrical shell 3 forms, and 100 of liquid refrigerants are intercepted by liquid barrier 1 and evaporate from newly getting back in the evaporimeter, thereby form and to have only gaseous refrigerant to go out to get back to compressor, avoid liquid hammer to cause compressor fault from evaporator outlet.
