Description

The ice plate type ice storage unit

Technical field:

The utility model relates to a kind of ice storage unit in the ice-storage system, definitely says so to be widely used in a kind of static ice storage unit in the air conditioner cold accumulation system.

Background technology:

Technology of Cold Storage Air Conditions is the emphasis power-saving technology of wideling popularize and developing at present.The guiding theory of this technology is to allow refrigeration unit miss the peak times of power consumption on daytime, during the night electricity load valley, move, the cold that produces is stored by cool storage medium ice, when next day, peak of power consumption had the refrigeration duty demand, discharge again for the user and use, reach the purpose of balanced network load, rational utilization of electricity and using electricity wisely.Ice storage unit is the nucleus equipment in the air conditioner cold accumulation system, though kind is many, but in actual engineering, use at present the CLAT ice hockey ice storage unit that has only France that more, performance indications and occupation rate of market have advantage, the BAC steel disk pipe ice storage unit of the U.S. and the round plastic coil pipe ice storage unit of U.S. Clamac.The subject matter that these several devices exist is: ice hockey ice-reserving and steel disk pipe ice-reserving, thus efficient is low because its icing thickness is big, the ice-reserving temperature is lower when causing the refrigeration machine ice-reserving; And ice hockey and plastic coil ice-reserving are being put the cold middle and later periods, because ice do not contact with solution interface, and cause putting cold efficiency reduction and put practical problem such as cold temperature instability.

Summary of the invention:

The purpose of this utility model is: overcome the shortcoming that above-mentioned ice storage unit exists, can improve refrigeration machine ice-reserving efficient and ice-reserving is put cold efficiency and had the stable ice plate type ice storage unit of cold temperature of putting for the user provides a kind of.

Goal of the invention of the present utility model realizes by implementing following technical proposals: a kind of ice plate type ice storage unit, by heat-insulation layer, and be encapsulated in the heat-insulation layer and form by a plurality of identical module of ethylene glycol overcurrent inner connecting tube level series connection, it is characterized in that: each module by organize number identical, up and down horizontal positioned, borneol assembly that structure is identical is superimposed and constitute; Each borneol assembly all is the closed container of a matrix, it is had the matrix sheet steel of certain width boss face by horizontal positioned, periphery about in the of two, form with its supporting steel plate all around of sealing, wherein go up the indent degree of depth of a matrix sheet steel boss face apart from its base plate face, the corresponding indent degree of depth greater than following sheet matrix sheet steel, on the bottom surface of two matrix sheet steel up and down of this container, be provided with two pairs of ethylene glycol flowing holes, every pair of flowing hole is all connected by an inner connecting tube, makes ethylene glycol and the interior space of container in the pipe isolated; On the boss face of the upper and lower two matrix plates of container, have upper and lower a pair of borneol layer water and fill mouth, with a pair of borneol layer gas vent, wherein be positioned at a borneol layer gas vent on the matrix plate boss face, connect one in the boss chamber, vertically down stretch, bleeder pipe that length equals last slice plate depth of recess; At last matrix panel edges place, the sealing dottle pin bar of crossing fluid layer in order to ethylene glycol between the upper and lower two ice cube chip modules of formation sealing is housed.Additional technical feature is: every module, compress panel all being equipped with on its top borneol assembly and under the borneol assembly of bottom, set bolt is by compressing the bolt connecting hole on the panel, with each borneol assembly compress, seal, fixing and form the module whole assembly.

Advantage of the present utility model is: 1. this device adopts the heat exchange principle of plate type heat exchanger, and heat exchange area is bigger; 2. its ice and the contact area of metal heat exchanger plates be greater than the steel disk pipe, thereby put cold efficiency and be higher than the steel disk pipe; On structure, because in each borneol assembly, the two ends of its concave-shaped receptacle, has the boss cavity body structure that fills air layer, needed expansion space when water freezing is provided in the borneol assembly, caused this layer borneol that a convexity layer is arranged simultaneously, can prevent that the upper strata layers of ice from not boning with metal structure, guaranteed that the upper strata layers of ice can float immediately when melting, lower floor's layers of ice also can float when the upper strata layers of ice will be use up, and go up the horizontal positioned of concave shape heat exchange plate, also provide condition for borneol come-up when melting, thereby improved greatly and put cold efficiency, make its performance surpass the steel disk pipe; 3. the volume of this device greatly reduces, thereby cost reduces greatly; Device is modular organization simultaneously, and the borneol assembly in each module all is independently, can change to be convenient to the dismounting maintenance; More than some is all superior than other ice storage unit.
