Description

Refrigeration system

Technical field

The utility model relates to refrigeration technology field, in particular to a kind of refrigeration system.

Background technology

In the prior art; All need use device for drying and filtering on the refrigerating plant such as refrigerator, wine cabinet; Device for drying and filtering often is placed in the pipeline of refrigeration system as a kind of filter; Generally device for drying and filtering is placed between the condenser and capillary of refrigeration system during production, is used for the cold-producing medium and the interior impurity of filtration system that flow in the dry refrigeration piping.Usually, after the parts of refrigeration system are welded to connect, will carry out evacuation process, make to reach in the pipeline after cleannes and the vacuum requirements again to system's perfusion refrigerant to refrigeration pipe.The technology that vacuumizes normally extracts on the process duct of compressor; And the structure of process duct is that bypass is on device for drying and filtering in the prior art; This structure is when welding, and the welding between process duct and device for drying and filtering is melted shorter deeply, is prone to the phenomenon that weldering is leaked; Welding procedure difficulty between feasible process duct aborning and device for drying and filtering is big, processing quality control is unstable, and randomness is big.

The utility model content

The utility model aims to provide a kind of refrigeration system, to solve refrigeration system annexation complicacy in the prior art.

To achieve these goals; The utility model provides a kind of refrigeration system; Comprise condenser, device for drying and filtering and capillary, device for drying and filtering is arranged between condenser and the capillary, and device for drying and filtering has the arrival end and the port of export; It is characterized in that the port of export of device for drying and filtering also is connected with process duct.

Further, process duct and capillary are arranged on the port of export of device for drying and filtering independently of each other, have between process duct and the capillary at interval.

Further, process duct comprises first pipeline section that is parallel to the device for drying and filtering axis and second pipeline section that is connected with first pipeline section and is provided with respect to the bending of first pipeline section.

Further, second pipeline section and the perpendicular setting of first pipeline section.

Further, the port of export of capillary and device for drying and filtering is welded to connect.

Further, the port of export of process duct and device for drying and filtering is welded to connect.

In the technical scheme of the utility model; Refrigeration system comprises condenser, device for drying and filtering and capillary; Device for drying and filtering is arranged between condenser and the capillary, and device for drying and filtering has the arrival end and the port of export, and the port of export of device for drying and filtering also is connected with process duct.The refrigeration system of the utility model; Cancelled the structure of process duct and device for drying and filtering bypass design, process duct has been connected the port of export of device for drying and filtering, this set; Simplified the annexation in the refrigeration system; And reduced the number of welds between process duct and the device for drying and filtering, and reduced the production cost of refrigeration system, promoted the part quality in the refrigeration system.

Description of drawings

The Figure of description that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:

Fig. 1 shows the sketch map that is connected according to the device for drying and filtering of the embodiment of the refrigeration system of the utility model, capillary and process duct.

The specific embodiment

Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the utility model.

Fig. 1 shows the sketch map that is connected according to the device for drying and filtering of the embodiment of the refrigeration system of the utility model, capillary and process duct; Referring to Fig. 1; As can be seen from the figure, the refrigeration system of present embodiment comprises condenser, device for drying and filtering 10 and capillary 20, and device for drying and filtering 10 is arranged between condenser and the capillary 20; Device for drying and filtering 10 has the arrival end and the port of export, and the port of export of device for drying and filtering 10 also is connected with process duct 30.The refrigeration system of present embodiment; Cancelled the structure of process duct 30 and the design of device for drying and filtering 10 bypass, process duct 30 has been connected the port of export of device for drying and filtering 10, this set; Simplified the annexation in the refrigeration system; And reduced the number of welds between process duct 30 and the device for drying and filtering 10, and reduced the production cost of refrigeration system, promoted the part quality in the refrigeration system.

In the present embodiment; Process duct 30 and capillary 20 are welded on the port of export of device for drying and filtering 10; In a kind of preferred embodiment, process duct 30 and capillary 20 are welded on the port of export of device for drying and filtering 10 independently of each other, have the gap between process duct 30 and the capillary 20.Such set-up mode; Make process duct 30 and capillary 20 being connected on device for drying and filtering 10 simple; Simplified production technology; Simultaneously process duct 30 is welded on the port of export of device for drying and filtering 10, the welding that has increased between process duct 30 and the device for drying and filtering 10 is melted deeply, has solved and has been easy to generate the problem that weldering is leaked between process duct 30 and the device for drying and filtering 10.

Process duct 30 in the present embodiment comprises first pipeline section and second pipeline section; Wherein, first pipeline section is parallel to the axis of device for drying and filtering 10, and first end of first pipeline section links to each other with the port of export of device for drying and filtering 10; First end of second pipeline section is connected second end of first pipeline section; And second pipeline section is provided with respect to the bending of first pipeline section, and preferably, second pipeline section is perpendicular to the first pipeline section setting.The process duct of this bending setting is convenient in the operation that refrigeration system is vacuumizing, operate, and has reduced the labour intensity in the operation that vacuumizes.

The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
