Abstract

The utility model discloses an ice-storage device of ice coiler, which comprises an ice groove, and a separator, a liquid trap and at least one deck of coiler which are arranged in the ice groove. Each deck of coiler comprises an inflow pipe and a flow-back pipe which are connected integrally, the space surrounded by the inflow and the flow-back pipes is of a plane-spiral shape, and the separator and the liquid trap are both arranged in the central area of the spiral-shaped space. The end portion of the inlet pipe is connected with the separator, and the end portion of the flow-back pipe is connected with the liquid trap. Because of the spiral-shaped space surrounded by the coilers, the flow directions of adjacent pipes are opposite and form convection. The temperatures of adjacent pipes can be compensated, and the water temperature in the ice groove can be more uniform. Only one separator is needed and the temperature compensation can be achieved by one coiler, thus the structure of the ice-storage device is simple. The utility model can save space because the separator and the liquid trap are arranged in the center of the coilers.

Description

Melt ice on coil ice storage unit and helical form coil pipe thereof

Technical field

The utility model relates to the ice storage unit in the air-conditioning refrigeration system, especially about a kind of coiled ice storage unit.

Background technology

In the society, electrical network peak valley electric power difference is more and more serious now, and wherein, it is increasing that the idle call electric weight accounts for the ratio of electric power peak load.The way that addresses this problem is that throwing huge fund sets up electric power facility on the one hand; On the other hand, the preferential electrovalence policy that utilizes country to put into effect moves on to low ebb with air conditioning electricity from the peak, and this has remarkable " peak load shifting " function to electrical network.The latter is the ice storage air conditioner technology that adopts the small investment instant effect, is a kind of important means that realizes " peak load shifting ".

The key equipment of ice-storage air-conditioning system is an ice storage unit, and its kind can be divided into four kinds of ice coiled pipe type, packaged type, flake ice landing formula and ice crystal formulas.Ice coiled pipe type ice storage unit such as notification number be CN2551956Y, the day for announcing are Mays 21 in 2003 day, to be called the Chinese patent of " a kind of fin serpentine coil ice storage device " and notification number be CN2324503Y, the day for announcing is disclosed by the Chinese patent that June 16 in 1999, day, were called " a kind of internal ice melting melt ice on coil equipment ".Wherein, notification number is that the melt ice on coil equipment that Chinese patent disclosed of CN2324503Y comprises upper and lower two knockouts, though solved the uniform problem of temperature, complex structure; Have only a knockout though notification number is the ice storage equipment that Chinese patent disclosed of CN2551956Y, coil pipe is connected simple inadequately with knockout.

Summary of the invention

Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, provides a kind of and can make even water temperature in the ice groove, simple in structure and save the melt ice on coil ice storage unit in space.

The technical solution adopted for the present invention to solve the technical problems is: this melt ice on coil ice storage unit comprises the ice groove and places knockout, liquid trap in this ice groove to reach one deck coil pipe at least, each layer coil pipe includes the inflow pipe that connects one and flows back to pipe, this inflow pipe and flow back to the intertubular space that pipe surrounds and be the snail shape, this knockout and liquid trap all place central zone of space between this helical coil, the end of this inflow pipe is connected with this knockout, and this end of flowing back to pipe is connected with this liquid trap.

Described inflow pipe and flow back to Guan Jun and be snail shape and centering on mutually, and this inflow pipe and to flow back to the hand of spiral of pipe opposite.

The inflow pipe of described each coil pipe and the axis coplane that flows back to pipe.

The coil pipe of described adjacent layer is staggered.

Described ice groove is circular.

The helical form coil pipe of this melt ice on coil ice storage unit comprises the inflow pipe that connects one and flows back to pipe, this inflow pipe and flow back to the intertubular space that pipe surrounds and be the snail shape, the end that the end of this inflow pipe and this flow back to pipe all places central zone of space between this helical coil.

The invention has the beneficial effects as follows, because coil pipe surrounds the intertubular space of snail shape, make the flow direction of adjacent tubes form convection current mutually on the contrary, so that the temperature between the adjacent tubes compensate mutually, make the water temperature in the ice groove more even, and owing to only need to be provided with a knockout, and each layer only need can realize temperature-compensating by a coil pipe, so whole ice storage unit is simple in structure; Simultaneously, because knockout and liquid trap place the center of whole coil pipe, so also can save the space.

The specific embodiment

See also Fig. 1 to Fig. 5, the utility model melt ice on coil ice storage unit comprises ice groove 1 and places knockout 4, liquid trap 3 in this ice groove 1 to reach one deck coil pipe 2 at least.This ice groove 1 is rounded.Each layer coil pipe 2 is by the inflow pipe 21 that connects one and flow back to pipe 22 compositions.This inflow pipe 21 is the snail shape, and its hand of spiral is counterclockwise.This flows back to pipe 22 and is the snail shape, and its hand of spiral is clockwise direction.This inflow pipe 21 and flow back to pipe 22 and center on mutually, and at this inflow pipe 21 with flow back to the intertubular space 23 that forms a snail shape between the pipe 22.The end of this inflow pipe 21 is connected with knockout 4, and this flows back to pipe end of 22 and is connected with liquid trap 3, and this knockout 4 and liquid trap 3 all place the central area of this intertubular space 23.The coil pipe 2 of adjacent layer is interspersed, and promptly the inflow pipe 21 of adjacent layer coil pipe 2 staggers mutually, and the pipe 22 that flows back to of adjacent layer coil pipe 2 staggers mutually.In the present embodiment, the inflow pipe 21 of each coil pipe and the axis coplane that flows back to pipe 22; The hand of spiral of this inflow pipe can be counterclockwise for the hand of spiral that flows back to pipe clockwise also, and the inflow pipe and the hand of spiral that flows back to pipe are got final product on the contrary.By with inflow pipe 21 and flow back to pipe 22 mutually around and form helical form intertubular space 23, not only make in the ice groove 1 temperature even, and simple in structure and save the space.

The course of work of this ice storage unit is divided into ice-reserving and two kinds of operating modes of ice-melt.In the ice-reserving operating mode, the glycol waters of 7～-4 degree enter coil pipe after by knockout, make the cooling of coil pipe outer wall and freeze, and then it is cooled again to get back to refrigeration machine through liquid trap, so circulation.In the ice-melt operating mode, the high temperature glycol aqueous solution flows through the cold that coil pipe absorbs ice, will ice gradually and melt, and sends for air-conditioning through the glycol water of cooling and uses.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
