Description

A kind of ice storage unit

Technical field

The utility model relates to a kind of cold-storage apparatus, particularly about a kind of air conditioner refrigerating energy storage U-shaped coil-type ice storage unit.

Background technology

Ice storage air conditioner is meant that the cold that utilizes refrigeration machine to make at night stores with the form of ice, air conditioner load peak period ice-out released cold quantity by day, partly or entirely satisfy the cooling demand, thereby reduce the installed capacity and the operation electricity charge of the cold machine of air-conditioning, reach desirable refrigeration and economic benefit.

State's inner coil pipe class ice-storage equipment kind is more at present, mainly comprises serpentine coil, two kinds of forms of screw type coil pipe.Heat exchange process is long but above-mentioned coil pipe class design form can exist brings the ice-storage equipment resistance drop bigger; Ice-reserving layer thicker relatively (about 25mm), ice making temperature relatively low (generally about-6 ℃); The size of equipment is bigger, is unfavorable for the transportation and the installation of equipment; If the damage of equipment, can't find the position of leakage point at all, can't realize the maintenance of equipment, can only change; Gap between the coil pipe is bigger, thereby required floor space is bigger, for the position of putting certain defectives such as requirement is arranged simultaneously.Thereby seek a kind of simple in structurely, with low cost, and installation and maintenance are convenient, and the cold-storage apparatus that refrigerating efficiency is high becomes the common problem of paying close attention to of present refrigeration circle.

Summary of the invention

At above problem, the utility model purpose provides a kind of high efficient and convenient ice storage unit that adopts the U-shaped coil pipe.

For achieving the above object, the utility model is taked following technical scheme: a kind of ice storage unit is characterized in that: it comprises an Ice Storage Tank, and described Ice Storage Tank sealing also contains water; In described Ice Storage Tank, be provided with at least one cover coil pipe assembly, described coil pipe assembly comprises one into and out of collector pipe, the described inlet tube and outlet tube that is communicated with some L-shaped settings on the collector pipe respectively side by side, the described other end into and out of collector pipe is a cecum, described water inlet pipe and described outlet pipe are provided with side by side at interval, each adjacent a pair of described inlet tube and outlet tube U-shaped coil pipe by some vertical settings respectively is communicated with, described into and out of collector pipe be communicated with respectively be arranged on described Ice Storage Tank outside refrigerating medium into and out of pipe.

Describedly be arranged side by side some joints that catchment on collector pipe, each described inlet tube and outlet tube is connected with the described joint that catchments by flange respectively.

Be respectively arranged with a protection tube on the described inlet tube and outlet tube of two outermost end of described every row's U-shaped coil pipe, the bottom of described protection tube is a cecum.

The quantity that is arranged on the described coil pipe assembly in the described Ice Storage Tank is more than the cover.

The described coil pipe assembly of every cover is connected in parallel into and out of pipe by valve and described refrigerating medium respectively.

Each described coil pipe assembly is connected in series into and out of pipe by valve and described refrigerating medium.

The diameter of described U-shaped coil pipe is 10～15mm.

The utility model is owing to take above technical scheme, and it has the following advantages: 1, the utility model is owing to adopt the ice-reserving effect of the low speed unhurried current of U-shaped coil pipe own, thereby resistance drop is very low, maintains about 40KPa substantially.2, the utility model is owing to adopt thinner diameter heat exchange U-shaped coil pipe between 10～15mm, and therefore the heat exchange area of other ice-storage equipment has bigger increase relatively, can reach 0.526m ²/ RT helps temperature field equilibrium in the Ice Storage Tank, effectively improves ice-melt speed.3, the utility model is because the ice-reserving layer thickness is less, and generally about 16mm, thereby the temperature of ice-reserving is higher relatively, generally can be about-4.5～-5 ℃.4, the utility model is because Ice storage coiled pipe is comparatively tight, and it is bigger that unit volume is held the ice rate, can reach 22.5RT/m ³Height, and can regulate the height of ice-storage equipment, thereby the floor space that can effectively reduce ice-storage equipment is not subjected to spatial constraints.5, the utlity model has the ice storage unit of U-shaped coil pipe, owing to adopt flange to connect, thereby can be by installing the means of maintenance valve additional, realize finding rapidly the position of leakage coil pipe, and monolithic U-shaped coil pipe keeped in repair from inner taking-up of cell body, after maintenance is finished, with its recovery.The utility model can be widely used in the energy storage device of air-conditioning system.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in detail.

As shown in Figure 1 and Figure 2, the utility model comprises coil pipe assembly 1, sealing Ice Storage Tank 2, and one or more coil pipe assemblies 1 are placed on collection to be had in the Ice Storage Tank 2 of water, and Ice Storage Tank 2 sizes and shape are according to the size and the quantity decision of coil pipe assembly 1.

As shown in Figure 1, the size of coil pipe assembly 1 designs according to refrigeration area or placing space, in an Ice Storage Tank 2, can have only a coil pipe assembly 1, also can be fitted together by several coil pipe assemblies 1.Coil pipe assembly 1 comprise one set up separately with both sides into and out of

collector pipe

11,12, on

collector pipe

11,12, be welded with some joints 13 that catchment respectively, each joint 13 that catchments is communicated with a L shaped inlet tube and

outlet tube

15,16 by a flange 14 respectively, and the other end of inlet tube and

outlet tube

15,16 is a cecum.Water inlet pipe 15 is provided with side by side at interval with outlet pipe 16.Each is communicated with by the independently U-shaped coil pipe 17 of some vertical settings respectively adjacent inlet tube and

outlet tube

15,16, and the quantity of U-shaped coil pipe 17 can be determined according to the length of refrigeration area and inlet tube and outlet tube 15,16.In two outermost end of every row's U-shaped coil pipe 17, be respectively arranged with a protection tube 18 that is communicated with water inlet pipe 15 or outlet pipe 16, the other end of protection tube 18 is a cecum.

As shown in Figure 2, Ice Storage Tank 2 comprises the three-decker in the routine techniques, and shell 21 is made by hot-dip galvanized steel sheet or color steel, and intermediate layer 22 is an insulation layer, and internal layer 23 is laid with the polyvinyl chloride waterproof membrane.The top cover of Ice Storage Tank 2 be provided with connection into and out of the refrigerating medium of

collector pipe

11,12 into and out of

pipe

24,25.

In the foregoing description, the coil pipe assembly 1 that is arranged in the Ice Storage Tank 2 also can be two or more, and each coil pipe assembly 1 is contacted or is connected in parallel by valve 19.When the needs dismounting is keeped in repair, can turn-off the valve 19 of faulty section, the flange 14 at Tear Down Deficiency place just can be removed the fault pipe, loads onto by flange 14 after reparation finishes again.In the foregoing description, U-shaped coil pipe 17 adopts the thinner pipeline of diameter between 10～15mm.
