Abstract
The utility model provides a dry type evaporator, comprising an evaporator cylinder and a pipe box. The dry type evaporator is characterized in that the evaporator pipe box is provided with an internally-arranged gas-liquid separator; a refrigerating agent outlet is arranged on in the evaporator pipe box; the refrigerating agent outlet is communicated with the gas-liquid separator; the evaporator pipe box is further provided with a refrigerating agent inlet; and the evaporator cylinder is further provided with a freezing water inlet and a freezing water outlet. The internally-arranged gas-liquid separator of the dry type evaporator disclosed by the utility model can effectively increase the overheat degree of a refrigerating agent gas so as to prevent a compressor from being compressed with liquid; and pressure drop of a refrigerating agent pipeline is reduced and the energy efficiency ratio of a set is improved. An internally-arranged expansion distribution mechanism is used for preventing an auxiliary pipeline from being artificially injuringdamaged an auxiliary pipeline in processes of transportation and the like; and the distribution of a refrigerating agent is more uniform so that the dry type evaporator can achieve the best heat-exchanging performance.
Description
Technical field
The utility model relates to a kind of refrigerating machine field, particularly a kind of dry evaporator.
Background technology
Dry evaporator is that the cold-producing medium of non-flooded evaporator flows in pipe, and water flows outside tube bank.Flow of refrigerant has several flow processs usually because the gradually gasification of refrigerant liquid, flow process more upwards, its flow process pipe number is more.In order to increase the heat exchange of water side, be provided with several deflection plates in the outside of the inboard heat-transfer pipe of cylindrical shell, make repeatedly flow across the bundle of water.And when refrigeration machine during at variable parameter operation, the cold-producing medium evaporation in the common dry evaporator not exclusively, thereby cause easily compressor band hydraulic compression to damage compressor.For addressing this problem, conventional way is to increase external gas-liquid separator, but can bring equally the problems such as cost is high, layout is difficult, the pressure drop of increase refrigerant line, reduction unit eer.
The utility model content
The purpose of this utility model is to provide a kind of effective increase refrigerant gas degree of superheat, avoids compressor band hydraulic compression; Reduce the refrigerant line pressure drop, improve a kind of dry evaporator of unit eer.
For solving the problems of the technologies described above, a kind of dry evaporator of the utility model comprises evaporator tube and bobbin carriage, it is characterized in that: be provided with built-in gas-liquid separator at the evaporimeter bobbin carriage, be provided with refrigerant outlet at the evaporimeter bobbin carriage, refrigerant outlet is communicated with gas-liquid separator; On the evaporimeter bobbin carriage, also be provided with refrigerant inlet; On evaporator tube, also be provided with chilled water import and chilled water outlet.
Preferably, be provided with built-in expansion distributor gear at described evaporimeter bobbin carriage; Described refrigerant inlet is communicated with described expansion distributor gear.
The built-in gas-liquid separator of a kind of dry evaporator of the utility model can effectively increase the refrigerant gas degree of superheat, avoids compressor band hydraulic compression; Reduce the refrigerant line pressure drop, improve unit eer, built-in gas-liquid separator can be cavity, entity cavity, pipeline, and wherein the form of pipeline section can be the shapes such as circle, rectangle, the straight trough degree of lip-rounding, ellipse, D shape.Built-in expansion distributor gear avoids in the processes such as transportation the people for damaging and associated ping, and it is more even that cold-producing medium is distributed, and dry evaporator can reach optimum heat exchange property; Manhole can also be reserved in built-in expansion distributor gear outside, maintains easily.

The specific embodiment
Below in conjunction with accompanying drawing a kind of dry evaporator of the utility model is described in further detail.
As shown in Figure 1, a kind of dry evaporator comprises evaporator tube 7 and evaporimeter bobbin carriage 8; Be provided with built-in gas-liquid separator 5 and built-in expansion distributor gear 6 at evaporimeter bobbin carriage 8.Be provided with refrigerant outlet 3 at evaporimeter bobbin carriage 8, refrigerant outlet 3 is communicated with gas-liquid separator 5.On evaporator tube 7, also be provided with chilled water import 1 and chilled water outlet 2; On evaporimeter bobbin carriage 8, also be provided with refrigerant inlet 4; Chilled water import 1, chilled water outlet 2 are communicated with evaporator tube 7, and refrigerant inlet 4 is communicated with expansion distributor gear 6.Built-in gas-liquid separator 5, built-in expansion distributor gear 6, these 2 parts all place evaporimeter bobbin carriage 7.Cold-producing medium through behind the expansion distributor gear 6 in the evaporation tube of evaporator tube 7 inside flow evaporation, overheated gaseous refrigerant leaves evaporimeter after processing through built-in gas-liquid separator 5.
The preferred embodiment of below the utility model having been created specifies, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the invention spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
