Abstract

The utility model discloses an ice storing ball, with a hollow sphere. Concave ball crowns of the same size and of an even quantity are equally arranged on an equator line of the sphere, and the concave ball crowns of the same size and of the same even quantity are equally arranged on two woofs of the same latitude on an upper hemisphere and a low hemisphere. The concave ball crowns on two woofs all take a ball core as a symmetrical center. Concave ball crowns are symmetrically arranged on the north and the south poles of the sphere, and bottoms of the two concave ball crowns on the north and the south poles are parallel to the equator plane, and a liquid hole is cut on one of the two concave ball crowns. The utility model can keep a ball casing from being broken by ice after ice is formed with the enlarged volume, so as to prolong the service life of the ball casing. The utility model can be used for an ice storage cold air conditioner system or a low temperature cold storage system.

Description

Ice-storing ball

The utility model relates to a kind of ice-chilling air conditioning system, deepfreeze system of being used for, and other need the cold-storage ball of low temperature environment.

Along with the increase year by year of need for electricity amount, particularly summer, the peak of power consumption load increased every year suddenly, and the annual substantial contribution that drops into all can not satisfy the demand of society for electricity consumption.For alleviating peak electricity consumption imbalance between supply and demand in summer, adopt a kind of ice making in late into the night cold-storage technology at present, promptly the building central air conditioner system is treated low power consumption period at night start ice making cold-storage, for peak of power consumption period next day air-conditioning cooling.During the night ice making, heat exchanger quits work, refrigeration machine is subzero about 8 degrees centigrade operations in evaporating temperature, low temperature ethylene glycol solution (non freezing solution) cold-storage groove of flowing through of circulation in the system, make the staggered Ice-storing ball that fills aqueous silicate solution in cold-storage groove begin the ice-reserving process, refrigeration machine is along with the reduction of the temperature of the non freezing solution that returns reduces its refrigerating capacity by energy adjustment gradually; Can release with Ice-storing ball in peak of power consumption period next day cold, the ethylene glycol solution cold-storage groove of flowing through of circulation in the system, Ice-storing ball obtains to carry out heat exchange with air-conditioning system recirculated water by plate type heat exchanger, Cooling Air-conditioning System recirculated water after the low temperature from cold-storage groove; When Ice-storing ball is released the cold junction bundle, again by the independent cooling of unit.Ice-storing ball is smooth hollow ball housing of sphere or bimetallic stamen Ice-storing ball in the above-mentioned ice-storage system, the Ice-storing ball of smooth ball housing is not considered the problem of dilatancy, and cost is lower, and is cheap, but Ice-storing ball through repeatedly expand and contraction distortion after, damage easily; The heat exchange efficiency height of bimetallic stamen Ice-storing ball, but because shape, structure are complicated, manufacturing cost higher and often between use the back to damage easily.

The purpose of this utility model is to provide a kind of Ice-storing ball of global shell being damaged because of freezing and expansion of can preventing.

The purpose of this utility model is achieved through the following technical measures: the spheroid of Ice-storing ball is hollow, and being evenly distributed with quantity on the equatorial line of described spheroid is even number and the identical recessed spherical crown of size; All being evenly distributed with quantity on two latitude lines of the same latitude of spheroid upper and lower hemispheres is even number and the identical recessed spherical crown of size, and the recessed spherical crown on described two latitude lines all is symmetrical centre with the centre of sphere; The south poles of spheroid is provided with the recessed spherical crown of symmetry, and two recessed spherical crown bottom surfaces on this south poles are parallel to equatorial plane, and offer inlet opening in one of them recessed spherical crown of south poles.

Described in the utility model is that the recessed spherical crown that distributes on the equatorial line is 6; Described latitude is 47 degree, and the recessed spherical crown that distributes on every latitude line is 4, and the recessed spherical crown on the latitude line is identical with recessed spherical crown size on the described equatorial line.

Each recessed spherical crown described in the utility model and hollow ball surfaces externally and internally intersection are arc transition.

Owing to be provided with the recessed spherical crown that is evenly distributed at hollow ball, when freezing volumetric expansion, these recessed spherical crowns are just to evagination, the STRESS VARIATION of having offset spheroid internal cause freezing and expansion and having caused, and these recessed spherical crowns all are symmetrical centre with the centre of sphere, whole spheroid stress equalization when making freezing and expansion, thus anti-stagnant ice forms the destruction of back volume increase to global shell, increases the service life.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 1 is the wherein front view of an embodiment of the utility model;

Fig. 2 is an A-A cutaway view embodiment illustrated in fig. 1;

Fig. 3 is a vertical view embodiment illustrated in fig. 1;

Fig. 4 is a side view embodiment illustrated in fig. 1.

As shown in Figures 1 to 4, the present embodiment spheroid is hollow, and sphere diameter is 100mm, ball wall thickness 2mm, and 6 the recessed spherical crowns that the bottom surface diameter is 36mm that on the equatorial line of spheroid, evenly distribute, the degree of depth of its depression is 3.35mm; Spheroid upper and lower hemispheres latitude is that 4 the bottom surface diameters that all evenly distribute are the recessed spherical crown of 36mm on two latitude lines of 47 degree, the degree of depth of its depression is 3.35mm, recessed spherical crown on two latitude lines is symmetrical centre symmetry in twos with the centre of sphere, and the recessed spherical crown bottom center on two latitude lines and the vertical height of the equatorial plane are 22.5mm; The south poles of spheroid is arranged with the recessed spherical crown that the bottom surface diameter is 28mm, the degree of depth of its depression is 2mm, this two recessed spherical crowns bottom surface is parallel to equatorial plane, and offer diameter 8mm inlet opening at the recessed spherical crown center of the spheroid arctic, be used for filling aqueous silicate solution, filling finishes uses polyethylene chock plug ultrasonic wave to melt the back sealing, and inlet opening also can be opened in the recessed spherical crown center in the spheroid South Pole.The part that above-mentioned all recessed spherical crowns and spheroid surfaces externally and internally intersect adopts circular arc excessive, excessively arc radius 2 to 4mm.

The utility model adopts high density olefin polymerization material to make, in use, with staggered in cold-storage groove behind the filled aqueous silicate solution of Ice-storing ball, during the night ice making, subzero about the 7 degrees centigrade ethylene glycol solution Ice Storage Tank of flowing through, solution in the Ice-storing ball is that the center begins to freeze with the tuberculosis agent that suspends, when icing volume during greater than the ice hockey volume, the spherical crown of depression partly begins projection, when the volume that freezes is in close proximity to volume with the spherical shell of Ice-storing ball radius calculation, the complete projection of spherical crown of depression forms spherical shell completely, and the rate of freezing this moment reaches about 95%, and freezing process stops.Need daytime Ice-storing ball to release when cold, the ethylene glycol solution of the high temperature ice cold-storage groove of flowing through, the ice in the Ice-storing ball begins ecto-entad and melts, Ice-storing ball progressively recover the to cave in reset condition of spherical crown.
