Description
Technical field
The present invention relates to air-conditioning shunting field, the part flow arrangement and air-conditioning of caliber error are more particularly to adapted to.
Background technology
With air-conditioning, usage amount is increased in life, work, and the heat transfer effect to air-conditioning is increasingly paid attention to.Air-conditioner is basic
It is made up of outdoor heat exchanger, indoor heat exchanger, system pipeline, compressor, control structure etc..Fig. 1 gives now air-conditioned changing
Heat structure, refrigerant (refrigerant) is flowed into from refrigerant intake line 105, by part flow arrangement 104, distribution to some distribution pipelines
Among 103.Every distribution pipeline 103 correspond to a heat exchange stream 102, and heat exchange stream 102 is and outer through over-heat-exchanger 101
There is heat exchange in boundary's environment (usually air or water), external heat is absorbed by phase transformation, realize the purpose of refrigeration.Heat is completed to hand over
Refrigerant (refrigerant) after commutation becomes collects concentration by refrigerant collecting 106, and is exported via refrigerant output pipe 107, from
And complete a heat exchanging process.
In air-conditioning heat exchange structure, current divider is critical component, and its shunting uniformity determines changing for whole heat-exchange system
The thermal efficiency, if there is the uneven phenomenon of shunting, then refrigerant (refrigerant) is on the high side in will causing partial flowpafh, heat exchange area
Relative deficiency, and refrigerant (refrigerant) is on the low side in partial flowpafh, heat exchange area is excessive, so as to result in whole heat-exchange system heat exchange
Efficiency reduction.Additionally, refrigeration system often works at different temperature, now the input gas liquid ratio of refrigerant (refrigerant) also can
There is larger difference, if part flow arrangement 104 can not keep shunting equal under different refrigerant (refrigerant) input gas liquid ratios
It is even, heat exchange efficiency decline is not only resulted in, and can cause under some cryogenic refrigeration operating modes, the output temperature of partial flowpafh is inclined
Situation that is low, producing uneven frosting even to freeze, has a strong impact on the normal work of heat-exchange system.
Fig. 2 gives a kind of existing part flow arrangement structure, and refrigerant enters part flow arrangement, is by fluid input section 201 first
Accelerate refrigerant to reduce gravity to shunting the influence of uniformity, interlude, interlude are entered after by fluid input section 201
Including refrigerant accelerating sections 202, hybrid chamber 203 and coolant distribution cone 204.To be flowed through from the refrigerant out of fluid input section 201 cold
Matchmaker's accelerating sections 202, its sectional area is obviously reduced compared with fluid input section 201.Hybrid chamber 203 is flowed into after refrigerant is accelerated, is promoted
Gas-liquid two-phase refrigerant mixes, and after then being shunted through coolant distribution cone 204, is exported to ensuing heat exchange by fluid deferent segment 205
Among stream.
Caliber error is to cause one of major reason of shunting inequality in above-mentioned flowing, as shown in Figure 3.In part flow arrangement
With the connecting portion of distribution pipeline, the line end caused by distribution pipeline one end is usually present due to pipeline cutting clout
Diameter deviation, the deviation may be shown as on pipeline central shaft mal-distribution.Refrigerant flow direction is respectively A or B in pipeline
When：
(1) when refrigerant flow direction is for A in pipeline, it is meant that refrigerant flows to distribution pipeline by part flow arrangement, in correspond to Fig. 2
Refrigerant part flow arrangement is flowed out by fluid deferent segment 205.Now, because the line end diameter deviation 2 in Fig. 3 is (also known as caliber
Deviation) it is random deviation, cause the linear loss of different diverter branch difference also occur, so that the small branch road of linear loss
The cold medium flux got is high, and the cold medium flux that the big branch road of linear loss is got is low, so as to produce shunting uneven, and thus causes
The problems such as heat exchange efficiency reduction and uneven frosting.
(2) when refrigerant flow direction is for B in pipeline, it is meant that refrigerant flows to part flow arrangement by distribution pipeline, in correspond to Fig. 2
Refrigerant part flow arrangement is flowed into by fluid input section 201.Now, because the line end diameter deviation 2 in Fig. 3 is on pipeline axle
The heart is asymmetric, hence in so that cold medium flux is also asymmetric on pipeline axle center.Due to it is this it is asymmetric be unpredictalbe, and
Part flow arrangement is, according to axle center symmetric design, therefore the cold medium flux that different branch is got to be caused inconsistent.So as to can also make
Into the uneven problem of shunting.
Sum it up, when part flow arrangement is connected with distribution pipeline, whether in input section, or deferent segment, can
Because caliber error produces the uneven problem of shunting.This is a problem demanding prompt solution for heat-exchange system.

In view of uneven problem is shunted in existing air-conditioning heat exchange structure, present technology provides dividing for adaptation caliber error
Stream device and air-conditioning.
Product, method etc. will be described in detail by basic engineering, extension design and alternative design below.
A kind of part flow arrangement for adapting to caliber error, as shown in Figure 4,5, it includes：The fluid input section 1 that is sequentially connected,
Interlude and fluid deferent segment；Fluid input lines are connected with fluid input section 1, transport fluid into interlude, and interlude enters
After the mixing of row fluid distribution pipeline, the output of fluid outlet line (also referred to as isocon) connecting fluid are discharged to from fluid deferent segment
Section.Wherein connected mode is generally using socket.Wherein, the first through hole of socket fluid input lines is set in fluid input section 1；The
The end face at the internal orifice end of one through hole sets first annular block face 4, the part of first annular block face 4 covering first through hole；It is first annular
Minimum diameter of the annular diameters of block face 4 less than all fluid input lines being socketed；Socket fluid is set in fluid deferent segment

The through hole of lid second；The minimum diameter of the annular diameters less than all fluid shunt lines being socketed of the second annular block face.Fluid
Can be supported with part flow arrangement supporting construction 3 outside input section, fluid deferent segment.
Referring herein to the annular block face of first annular block face 4, second be provided to reduce first through hole or the second through hole
Internal orifice port footpath, main reason is that the internal orifice end of first through hole, the second through hole has caliber error, annular block face is once less than
The minimum diameter of any one open ended pipeline, then the annular diameters of annular block face be internal orifice port footpath, be that fluid passes through
Bore, i.e., the bore of the fluid that the inner ring bore of annular block face is determined, the influence departing from caliber error to fluid bore.Need
It is noted that it is first, second that annular block face, through hole etc. are not numbered herein, reason is to be used in the case of two kinds
Principle it is identical, therefore, the main principle of specification of this section, ask those skilled in the art voluntarily match.
Because the annular block face of first annular block face 4, second is processed by high accuracy turning, its mismachining tolerance is much smaller than pipe
Line end diameter deviation 2 caused by road cutting clout, therefore, for the fluid deferent segment of part flow arrangement, using second
Annular block face controls the minimum diameter of local pipeline, it is ensured that the minimum diameter in every diverter branch be all it is consistent,
Thus can ensure that the linear loss in every diverter branch is roughly equal, so as to avoid the occurrence of dividing between each bar diverter branch
Stream is uneven；For the pipeline of fluid input section 1 of part flow arrangement, because first annular block face 4 is formed by turnery processing, its tool
There is axial symmetry very high, it is ensured that refrigerant flow field is also uniformly distributed along input pipe axis, it is remaining so as to avoid pipeline cutting
Refrigerant flow field deflection caused by material, it is to avoid the shunting inequality situation for therefore occurring.
It is that fluid input lines become a mandarin from collar extension end to internal orifice end set for relative interlude referring herein to internal orifice end
In body input section 1, the medial surface of first annular block face 4 is withstood on；It is defeated that fluid outlet line is inserted in fluid from collar extension end to internal orifice end
Go out in section, withstand on the medial surface of the second annular block face.
Because different types, fluid input lines, the caliber difference of fluid outlet line, so, first annular block face 4
Compared with minimum pipe in open ended all fluid input lines, less than the minimum pipe.The inner ring of the second annular block face
Bore duplicates, and here is omitted.
In order to further increase the symmetrically property of shunting, vertical center axis and the first through hole of first annular block face 4
Central axis.Fluid still coaxially passes through first annular block face 4, with axle pair very high from after fluid input lines discharge
Claim property, it is ensured that refrigerant flow field is also uniformly distributed along input pipe axis, so as to avoid pipeline cutting clout caused by refrigerant
Flow field deflection, it is to avoid the shunting inequality situation for therefore occurring.
The vertical center axis and the central axis of the second through hole of the second annular block face.Principle is ibid.
Directly caliber deviation (also known as diameter deviation) is compared below by some embodiments, first annular block face 4
Inner and outer ring between width more than first through hole hole inwall and the inner surface of first annular block face 4 between diameter deviation 2.
Reduce influence of the diameter deviation 2 to fluid entry port footpath.
Second annular block face is similar, the width between the inner and outer ring of the second annular block face more than the second through hole hole inwall and
Diameter deviation 2 between the inner surface of the second annular block face.Reduce influence of the diameter deviation 2 to fluid flow outlet footpath.
Based on above-mentioned various schemes, the minimum diameter in each diverter branch is controlled due to caliber control step, therefore respectively
Branch road linear loss has risen, if be not compensated for, can produce influence to the efficiency of refrigeration system.Therefore must be mended
Repay and balance.So, interlude includes the first balancing segment 5, the second balancing segment, during the first balancing segment 5, the second balancing segment are respectively in
Between section one end；First balancing segment 5 is in parallel with the first annular block face 4 of fluid input section 1, the second balancing segment and fluid deferent segment
The second annular block face it is in parallel.First balancing segment 5, the second balancing segment realize linear loss.
Wherein, the bore of one end of the connecting fluid input section 1 of the first balancing segment 5 is straight equal to the inner ring of first annular block face 4
Footpath, and less than the bore of the other end of the first balancing segment 5；The bore of one end of the second balancing segment connecting fluid deferent segment is equal to second
The annular diameters of annular block face, and less than the bore of the second balancing segment other end.Reduce after first annular block face 4 or the second annular
The refrigerant flowing linear loss of latter section of pipeline of block face, so that the refrigerant flowing linear loss rising that annular block face causes is compensated,
So that total refrigerant flowing linear loss is held essentially constant compared with the state before increasing annular block face.So, can in realization
While adapting to caliber error uniform divided flows, also it is avoided that the method produces influence to the efficiency of refrigeration system.
Several first balancing segments 5, the appearance form of the second balancing segment, in these forms, the first balancing segment is given below
5th, the second balancing segment can use same, it would however also be possible to employ variety classes, be write a Chinese character in simplified form with balancing segment below.
