Description

The water-locator of water chilling air conditioning system
Technical field
The utility model relates to a kind of cold-storage device, relates in particular to a kind of water-locator of water chilling air conditioning system.
Background technology
The principle of water cold-storage technology realizes according to water its density difference under different temperature.Under the atmospheric pressure, the density of 4 ℃ water is maximum, and be 1000kg/m this moment 3, when water temperature was no matter still low than 4 ℃ than 4 ℃ high, its density all can reduce.When the water surface of two kinds of different temperatures contacts; The water that can present high temperature in the above; The water of low temperature below, there is a thermoclinic phenomenon of transition the centre, the phenomenon of this water natural layering is used in and just is called as natural layering formula water cold-storage technology in the water cold-storage technology.Water chilling air conditioning system cardinal principle is to be stored in the cold-storage device at the cold water that the low power consumption time will about 4-6 degree, in the peak of power consumption time period cold water that stores is discharged use, has reached the purpose of saving operating cost and electric power " peak load shifting ".
The key technology of water cold-storage is to guarantee mesolimnion thickness uniformity, and mesolimnion is flowed by ambient water to influence, the mobile influence that receives flow resistance of water, and the consistent water flows of resistance is even, and mesolimnion thickness will uniformity.The actual at present cold-storage mode of using can be divided into: natural layering formula, labyrinth type, diaphragm type etc., wherein the natural layering formula has occupied more than 95%.Patent No. ZL200820055593.1 discloses three water distribution water cold accumulation devices of a kind of H type; H type water distribution is simple in structure; But because the perforated area of each water distributing pore size is the same, and different, according to fluid resistance losses formula in the liquid mechanics: drag overall P=△ P from cloth supply mains's distance f+ △ P z, straight length resistance △ P f=ρ λ Lv2/2d is in the formula: ρ-Media density (kg/m 3), λ-frictional resistance factor, v-velocity of medium (m/s), L-straight pipeline length (m), d-inside diameter of straight pipe section (m), local resistance △ P z=ξ λ L eV2/2d e, in the formula: ρ-Media density (kg/m 3) ξ-coefficient of partial resistance, v-velocity of medium (m/s), L eThe equivalent length of-perforate (m), d eThe equivalent internal diameter (m) of-perforate can be found out, the local resistance far away from the cloth supply mains is big; Otherwise resistance is little; So the water yield in each hole is different among the patent No. ZL200820055593.1, thereby cause the thickness of oblique flow layer thickness to differ, cold efficient is put in holding of influence.Patent No. ZL200810183585.X discloses a kind of device that under the cloth pond, reaches water distribution uniformity again through the current-sharing damping sheet, though part has solved the problem that the former exists, its design is too complicated, and cost is too high, difficult installation.
Summary of the invention
The utility model causes mesolimnion thickness is inconsistent and a kind of water-locator is provided everywhere to water-locator flow in the prior art is irregular, makes the mesolimnion uniformity in the water-locator, has improved holding in the water cold-storage technology and has put cold efficient.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is:
A kind of water-locator of water chilling air conditioning system; Comprise cold-storage groove and connect the inside and outside aqueduct of cold-storage groove; Said aqueduct comprises the last water delivery trunk line and following water delivery trunk line that is arranged on the cold-storage groove middle part; The said water delivery trunk line top of going up is connected with the last water distribution pipe that has the water distributing pore I; Following water delivery trunk line below is connected with the following water distribution pipe that has the water distributing pore II, and the perforated area of the water distributing pore II on the said perforated area of going up the water distributing pore I on the water distribution pipe and the following water distribution pipe is all by the Geometric Sequence setting, and wherein the nThe area in hole equals N-1The area in hole multiply by r, and r is the common ratio of Geometric Sequence.
Said last water delivery trunk line and following water delivery trunk line, last water distribution pipe and following water distribution pipe and water distributing pore I and water distributing pore II are about cold-storage groove center line symmetry.
Spacing between the said water distributing pore I that goes up on the water distribution pipe equates that the spacing between the water distributing pore II on the following water distribution pipe equates.
The utility model is offered the water distributing pore of corresponding size according to the difference of being responsible for distance apart from water distribution, makes the flow of each water distributing pore be consistent, and has guaranteed the mesolimnion uniformity in the water-locator, has improved to hold and has put cold efficient.
Description of drawings
The structural representation of Fig. 1 the utility model.
The structural representation of Fig. 2 water distributing pore.
The specific embodiment
Like Fig. 1, shown in Figure 2; A kind of water-locator of water chilling air conditioning system; Comprise cold-storage groove 1 and connect the inside and outside aqueduct of cold-storage groove; Aqueduct comprises the last water delivery trunk line 2 and following water delivery trunk line 3 that is arranged on the cold-storage groove middle part; Last water delivery trunk line 2 tops are connected with the last water distribution pipe 4 that has water distributing pore I 6, and following water delivery trunk line 3 belows are connected with the following water distribution pipe 5 that has water distributing pore II 7, and the perforated area of the water distributing pore II 7 on the perforated area of the water distributing pore I 6 on the last water distribution pipe 4 and the following water distribution pipe 5 is all by the Geometric Sequence setting.Last water delivery trunk line 2 and following water delivery trunk line 3, last water distribution pipe 4 and following water distribution pipe 5 and water distributing pore I 6 and water distributing pore II 7 are about cold-storage groove center line symmetry.Spacing between the water distributing pore II 7 under reaching between the water distributing pore I 6 on the last water distribution pipe 4 on the water distribution pipe 5 equates.
