Description
Technical field
The invention belongs to field of air conditioning, more particularly, to a kind of aligning method of Ice storage coiled pipe.
Background technology
Ice-storage equipment is generally used for central air conditioner system.During low power consumption, the cryogenic freezing liquid that refrigeration machine is made
Ice-storage equipment is passed through, the water outside ice-storage equipment serpentine coil is build-up ice；During peak of power consumption, freezing liquid flows through snakelike disk
Pipe, by heat exchange, takes away the cold of the outer ice of serpentine coil, is directly sent to air conditioning terminal or cold is sent into air-conditioning by heat exchanger
End.Using the equipment, air-conditioning quality can be improved, operation of air conditioner expense is reduced.
Current existing ice-storage equipment aligning method mainly has following 5 kinds：
1st, equidistant fork row, as shown in figure 1, a/b ≈ 2
2nd, square arrangement, as shown in Fig. 2 a/b ≈ 1
3rd, regular hexagon is arranged, as shown in figure 3,
4th, not equidistant biserial overlap joint arrangement, as shown in figures 4 a and 4b, a/ (b1+b2) ≈ 1
5th, the single-row overlap joint arrangement of elliptical tube, as shown in figure 5 a and 5b, a/b ≈ 1
Size a is serpentine coil elbow central diameter in figure, and b is the spacing between adjacent serpentine coil, and dotted line is ice ring
Outer surface.
Above method do not take into full account on serpentine coil ice layer thickness with freezing liquid flow direction reduce the problem of.
Wherein method 1 and the icing rate of method 2 is too low；Method 3 reaches when ice layer thickness is consistent on each section on coil pipe on icing rate theory
Maximum is arrived, because the adjacent ice ring thickness of the same serpentine coil at feed liquor house steward is big, actual overlap joint is serious；Method 4
On the one hand in order to improve ice-storage rate, on the other hand in order to avoid mutually being extruded after being frozen on whole ice-storage equipment inner coil pipe, by snake
Arrangement design between shape coil pipe is into not equidistantly, so that icing overlap joint is limited between two disks, one group of serpentine coil, but ice
Layer increases faster Yi Dan ice thickness after overlap joint as ice amount increases, and ice sheet external surface area no longer increases with the increase of ice thickness
Plus, as shown in Figure 4 b, cause heat transfer efficiency to reduce rapidly, influence ice making efficiency, while between adjacent two layers coil pipe ice extruding
Still have, influence is existed on the service life of ice-storage equipment；Method 5 is similar with method 4, in order to improve ice-storage rate and avoid
Mutually extruded after being frozen on whole ice-storage equipment inner coil pipe, serpentine coil is designed into ovalisation, the ice making later stage is made in arrangement
Icing overlap joint is limited on a serpentine coil, as shown in Figure 5 b, similar with method 4, and this arrangement can equally reduce heat transfer efficiency
With influence coil pipe service life.
The content of the invention
It is an object of the invention to for the deficiencies in the prior art, there is provided a kind of aligning method of Ice storage coiled pipe.
Therefore, the above-mentioned purpose of the present invention is achieved through the following technical solutions：
A kind of aligning method of Ice storage coiled pipe, the aligning method of the Ice storage coiled pipe includes：By the adjacent snake of any two
Using reverse arrangement between shape coil pipe, the cross-sectional distribution of serpentine coil causes the ice ring of adjacent two layers pipe in same serpentine coil
Just tangent in finishing ice-making, the ice ring of adjacent two layers pipe is also just tangent in finishing ice-making in adjacent serpentine coil；Root
Serpentine coil is divided into n-layer along the direction flowed from freezing liquid according to the backhaul number of serpentine coil, interior ice ring is not taken during ice making
In the case of connecing, the ice ring external diameter of each layer serpentine coil be respectively D1, D2 ..., Dn-1, Dn, phase on same serpentine coil
The centre-to-centre spacing of adjacent two layers of pipe is that the horizontal spacing between a, adjacent two serpentine coils is phase in b, adjacent two serpentine coils
The centre-to-centre spacing of adjacent two layers of pipe is c；Make it that the maximum two neighboring ice ring of ice ring thickness is not overlapped on same serpentine coil, is obtained
Minimum value to a is (D1+D2)/2；Due to being arranged between the adjacent serpentine coil of any two using reverse, then one layer of snake
The ice ring that external diameter is D1 in shape coil pipe is adjacent with the ice ring that external diameter is Dn in adjacent one layer of serpentine coil, similarly, the snakelike disk
The ice ring that external diameter is D2 in pipe is adjacent with the ice ring that external diameter is Dn-1 in adjacent one layer of serpentine coil, by that analogy；Pass through heat friendship
The calculating changed, (D1+Dn) ≈ (D2+Dn-1) ≈ (D3+Dn-2) ≈ ... ≈ (Dn-1+D2) ≈ (Dn+D1), to cause adjacent two
Do not overlapped between the ice ring of adjacent two layers pipe in root serpentine coil, then c minimum value is (D1+Dn)/2；According to Pythagorean theorem
And a and c minimum value, the minimum value for obtaining b is：
In fact, the ice thickness on same straight length (namely same layer) is gradually reduced along freezing liquid flow direction, i.e.,
The change of ice thickness is continuous, for the ease of designing and manufacturing, and serpentine coil has been done discrete processes, that is, is assumed in same straight tube
Ice thickness is equal on the Duan Tongyi times, and the change of ice thickness only occurs in different straight lengths；Certainly because any two is adjacent
Inversely arranged between serpentine coil, therefore, the result that discretization is obtained is can be obtained through continuous processing under practical situation
Ice-reserving process.
While using above-mentioned technical proposal, the present invention can also be used or combined using technology further below
Scheme：
When Ice storage coiled pipe is arranged in Internal melt system, a/b ratio range is 1.22~1.42.
When Ice storage coiled pipe is arranged in exo-melting ice system, a/b ratio range is 1.15~1.30.
The present invention provides a kind of aligning method of Ice storage coiled pipe, and arrangement in this manner, ice-storage equipment does not have in icing
It is highest to have the ice making rate before overlap joint, and the lapping time between each pipe is almost synchronous, and when close to overlap joint, system stops system
Ice, therefore, is produced, ice making efficiency is higher than other arrangement modes, and avoids in whole ice-making process without ice ring overlap joint phenomenon
Because between Ice storage coiled pipe caused by ice ring is overlapped mutually extruding and influence is produced on the ice-storage equipment life-span.
