Description

A kind of internal ice melting melt ice on coil equipment

The utility model relates to the cold-storage apparatus in a kind of air-conditioning refrigeration system, relates in particular to a kind of internal ice melting ice-storage equipment.

In recent years, along with China's rapid economy development, urban industry and non-technical electric weight all increase sharply, and cause to occur serious peak-valley difference in the operation of power networks in the daytime, greatly affect the efficient and the safety of electrical network.The ratio that air conditioning electricity accounts in the urban power consumption is then increasing, and is focused mostly in peak times of power consumption on daytime, causes huge pressure for the electrical network electricity consumption.In order to address this problem, generally use and study cool storage air conditioning technology and equipment thereof at present both at home and abroad.Cool storage air conditioning technology is exactly to add cold-storage apparatus and system thereof in traditional air-conditioning refrigeration system, and it can be at electricity consumption low peak period cold-storage, and peak times of power consumption put cold, is a kind of important means that realizes " peak load shifting ".

Using at present more in cold accumulation air-conditioner equipment is ice storage air conditioner equipment, and its kind can be divided into four kinds of ice coiled pipe type, packaged type, flake ice landing formula and ice crystal formulas.Wherein first kind is divided into internal ice melting and external-melting type again.The snakelike melt ice on coil of steel pipe type that the BAC company that external more representational internal ice melting ice-storage equipment is the U.S. produces, this melt ice on coil its on row and descend row that fin is all arranged most, knockout is designed to one simultaneously, and import and export has automatic valve control, also has the air pump agitating device.The shortcoming of this equipment is a complex structure, the manufacturing cost height; Constantly advance simultaneously oxygen in the water and can accelerate corrosion, shortened the life-span of equipment coil pipe.U.S. Fafco company adopts plastics U-shaped tubular type melt ice on coil, and the caliber of this coil pipe is very thin, has only 6.35mm, and resistance is bigger, and joint is more, the manufacture technology complexity, and difficulty is big.

China's utility model patent " double evaporators Ice-Storing Air-Condition device " (patent No.: disclosed a kind of internal ice melting snake type coil pipe ZL95212430.0), in the ice groove, adopt one to advance one time knockout pipeline, overcome above-mentioned melt ice on coil complex structure, the defective that manufacturing cost is high, but its shortcoming is that the temperature field is even inadequately in the ice groove, and flow path resistance is bigger in the pipe.

The purpose of this utility model and task are at the deficiencies in the prior art and defective, provide a kind of not only simple in structure, and cost is lower, and the temperature field is even in the ice groove, assembling internal ice melting cold-storage apparatus flexibly and fast.

The purpose of this utility model and task are achieved through the following technical solutions: it mainly is made of ice groove and melt ice on coil two parts of putting within it, and melt ice on coil comprises parts such as serpentine coil, inlet tube, outlet, tube sheet and knockout; It is characterized in that inlet tube and outlet respectively are divided into upper and lower two inlet ductwork and export pipelines that also link to each other with knockout respectively in the ice groove; Described tube sheet is to be lived in connecting by a plurality of parts in forming.

Accompanying drawing 1 is a front view of the present utility model.

Accompanying drawing 2 is the side view of melt ice on coil.

Accompanying drawing 3 is the pipe layout drawing of melt ice on coil.

Accompanying drawing 4 is for supporting the tube plate structure and the connection layout thereof of melt ice on coil.

Below in conjunction with description of drawings concrete structure of the present utility model, principle and preferred forms:

Internal ice melting ice-storage equipment of the present utility model mainly comprises ice groove (1) and puts within it melt ice on coil (2) two large divisions.Melt ice on coil (2) comprises serpentine coil (3), inlet tube (4), outlet (5), tube sheet (6) and knockout parts such as (7). the inlet tube of melt ice on coil and outlet respectively are divided into two pipelines that advance scene 2 after entering ice groove (1), promptly inlet tube (4) is divided into upper and lower two inlet ductwork (4a), (4b); Outlet (5) is divided into upper and lower two inlet ductwork (5a), (5b), links to each other with four knockouts (7) respectively then, and knockout is made by pipe or square tube or rectangular tube.Pipeline (4a), (5a) link to each other with pipe (4), (5) respectively in the side upper end of melt ice on coil (2); Pipeline (4b) (5b) in the side lower end of melt ice on coil (2), links to each other with pipe (4), (5) respectively, and each knockout links to each other with serpentine coil (3), goes out under enterprising thereby form one, the loop that goes out on time advancing.

In order to improve the ice-storage rate of cold-storage apparatus, the cross arrangement that serpentine coil (3) adopts row distance and line-spacing not to wait, all pipes all adopt hot galvanized steel pipe or are plastic tube.

Tube sheet (6) in the melt ice on coil (2) is to be lived in connecting with bolt by many clod wash channel-section steels (9) in forming, and has semicircle orifice (10) on the channel-section steel, is used for the location and the support of serpentine coil (3).It is easy to process that this structure can make melt ice on coil have, the dismounting flexible characteristic.

Ice groove (1) cooperates melt ice on coil (2) to be assembled into one, and melt ice on coil (2) seat is on the plate inner wall of ice groove (1).The circumferentially-spaced of ice groove and melt ice on coil generally should keep 30～200mm; Melt ice on coil should be 80～250mm with the spacing of the top cover inwall of ice groove.

Below its course of work is summarized as follows :-10～-4 ℃ 7 two alcohol solutions from refrigeration unit is come, behind inlet ductwork (4a), (4b), enter continuous knockout by pipeline (4) respectively, enter serpentine coil (3); Get back to outlet (5) behind knockout through linking to each other and export pipeline (5a), (5b) again.It is cooled again that 7 two alcohol solutions in the outlet (5) return refrigeration unit, so circulation.During this period, begin to freeze on serpentine coil (3) outer wall, until the ice-reserving amount that reaches design, this is the ice-reserving operating mode.During the ice-melt operating mode, glycol water is 1～10 ℃, and solution absorbs the cold of ice by serpentine coil (3), sends then, has melted until icing all, the course of work of Here it is internal ice melting ice-storage equipment.

The utility model compared with prior art has the following advantages and beneficial effect: this equipment not only has Technology is simple, the characteristics that equipment cost is lower; Simultaneously since melt ice on coil adopted two advance scene 2 design and Therefore tube sheet draw bail alive also has the interior flow path resistance of pipe and reduces, the interior uniform temperature fields of ice groove, and ice-reserving melts The constant rate of ice and melt ice on coil assembling flexibly and fast wait advantage.
