On 7, the length of the first heat exchanging segment 611 and the second heat exchanging segment 621 is the first capillary 61 and the welding of the second capillary 62 at this time
The length being fixed on muffler 7；Wherein, since the diameter of capillary is much smaller than the diameter of muffler 7, the first heat exchanging segment
611 and second heat exchanging segment 621 can be respectively welded on muffler 7, can also be the first heat exchanging segment 611 and the second heat exchanging segment
621 weld together after be welded to again on muffler 7, can realize the purpose of the application, objective is without departing from the present invention
Design philosophy, should belong to the scope of protection of the present invention.
It should be noted that 611 and second heat exchanging segment 621 of above-mentioned first heat exchanging segment can also be solid in other way
It is scheduled on muffler 7, is such as wrapped on muffler 7 or by being fastened on muffler 7 by aluminium foil, can
The purpose for realizing the application, should belong to the protection domain of the application.
Wherein the length of heat exchanging segment only refers only to relativeness in above-described embodiment, can be according to the refrigerator of different model
It is specifically chosen the length of the heat exchanging segment to exchange heat with muffler 7 on different capillaries, the total length with capillary is 3000mm
For, the length of the first heat exchanging segment 611 can select 500-1800mm according to the use environment of refrigerator, and the second heat exchanging segment 621
1000-2500mm can be selected, optionally, 611 length of the first heat exchanging segment is 1500mm, the length of the second heat exchanging segment 621
For 2000mm；Certainly, the length range of different heat exchanging segments can be selected on the different refrigerator of capillary total length.
Optionally, device for drying and filtering 3 is additionally provided between the condenser 2 and commutator 4, the device for drying and filtering 3 enters
Mouth is connected with the outlet of condenser 2, and outlet is connected with the entrance of commutator 4, can not only be removed by the way that device for drying and filtering 3 is arranged
The residual moisture of refrigeration system to which anti-stagnant ice is stifled, and reduces corrosiveness of the moisture to refrigeration system, and can filter out system
Impurity in cooling system, such as metal fillings, various oxides and dust etc., so as to avoid the first capillary 61 and second mao
Tubule 62 is dirty stifled；Meanwhile the commutator 4 can be solenoid valve or dynamoelectric switching valve, or other control valves, only
It wants that the purpose for switching different capillary work can be played, just can achieve the object of the present invention.
It should be noted that in the above-described embodiments, the capillary unit can have more capillaries in parallel, such as
Three (as shown in Figure 3), four, five etc., the purpose of the application may be implemented, can be selected according to different temperature ranges
The quantity of capillary in parallel is selected, number of capillaries in parallel is more, and the ambient temperature range that can adapt to is with regard to wider.
Embodiment two
The present embodiment is substantially the same its main distinction with the technical solution in embodiment one and is, the capillary unit is also
Including common segment 63, multiple capillaries are connected by common segment 63 with the entrance of the evaporator 5 respectively, the common segment
63 be also capillary pipe structure.
As shown in Fig. 2, refrigeration system provided in this embodiment, including compressor 1, condenser 2, evaporator 5, commutator 4
And capillary unit, the entrance of the condenser 2 are connected with the outlet of compressor 1, the outlet of the condenser 2 passes through capillary
Unit is connected with the entrance of evaporator 5, and the entrance of the evaporator 5 is connected by muffler 7 with the entrance of compressor 1, described
Capillary unit includes more capillaries in parallel, the length for the heat exchanging segment that the more capillaries exchange heat with muffler 7
It is all different, and commutator 4 is set between capillary and condenser 2, entrance is connected with the outlet of condenser 2, outlet point
It is not connected with the entrance of the more capillaries, the capillary to work, extraneous different temperatures is switched by commutator 4
Under, it can be worked by heat exchanging segment of the switching with different length, ensure to be not in return-air liquid under various operating modes
Hit phenomenon, at the same can also compressor 1 there is higher working efficiency.
Wherein, capillary unit described in the present embodiment as shown in Figure 2 further includes common segment 63, and two are equipped with capillary
It is a, and for its total length is 3000mm, the first capillary 61 and the second capillary 62 it is identical, at this time the first capillary 61 plus
The length of upper common segment 633 is 3000mm, and it is 3000mm that the length of the second capillary 62, which adds the length of common segment, ensures two
The total length of capillary pipeline is constant, to ensure that degree of supercooling will not change；The length of first heat exchanging segment 611 can make according to refrigerator
500-1800mm is selected with environment, and the second heat exchanging segment 621 can select 1000-2500mm, optionally, first heat exchanging segment
611 length are 1500mm, and the length of the second heat exchanging segment 621 is 2000mm；It certainly, can on the different refrigerator of capillary total length
To select the length range of different heat exchanging segments.
In the higher operating mode of ambient temperature, commutator 4 can be switched, condenser 2 is made to pass through the first capillary 61 and evaporation
Device 5 be connected to, at this time since 611 length of the first heat exchanging segment on the first capillary 61 is smaller, the heat exchanged with muffler 7 compared with
Less, therefore from evaporator 5 temperature for returning to the refrigerant in compressor 1 is relatively low, it can be ensured that compressor 1 has under high temperature environment
There is higher working efficiency；Can be that condenser 2 passes through the second capillary by switching commutator 4 when extraneous temperature is relatively low
62 are connected to evaporator 5, since the length of the second heat exchanger tube on the second capillary 62 is longer, the heat exchange with muffler 7
The heat of area bigger, exchange is more, the temperature that the refrigerant in compressor 1 is returned to from evaporator 5 can be improved, it is ensured that gaseous
Liquid refrigerant will not be mixed in refrigerant, guarantee is not in return-air liquid hit phenomenon, so that compressor 1 is worked normally, carries
Rise the working efficiency and service life of compressor 1.
Optionally, first heat exchanging segment, 611 and second heat exchanging segment 621 is to be fixed on muffler by welding
On 7, the length of the first heat exchanging segment 611 and the second heat exchanging segment 621 is the first capillary 61 and the welding of the second capillary 62 at this time
The length being fixed on muffler 7；Wherein, since the diameter of capillary is much smaller than the diameter of muffler 7, the first heat exchanging segment
611 and second heat exchanging segment 621 can be respectively welded on muffler 7, can also be the first heat exchanging segment 611 and the second heat exchanging segment
621 weld together after on being welded to muffler 7, can realize the purpose of the application, objective is without departing from the present invention's
Design philosophy should belong to the scope of protection of the present invention.
