Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment
As shown in Figure 1, a kind of efficient Ice Storage Tank that can regulate ice content of the utility model, comprise screen pack 3, water fender 4, frozen water be separated filter screen 5, electric heater 6 and be provided with the Ice Storage Tank casing 2 of subcooled water import 1 and cooling water outlet 7, Ice Storage Tank casing 2 top and the bottom have draw-in groove 9, draw-in groove 9 extends along water (flow) direction, is arranged in parallel within four ribs in Ice Storage Tank casing 2; Screen pack 3 size is mated with Ice Storage Tank casing 2, and is provided with four breach mated with draw-in groove 9, and therefore screen pack 3 can at Ice Storage Tank casing 2 along or against current movement arbitrarily; Water fender 4 adopts lucite material, and size is mated with Ice Storage Tank casing 2, can be inserted in draw-in groove 9 or take out, when water fender 4 is inserted in draw-in groove 9, Ice Storage Tank being divided into left and right two parts, and the fixation certain to screen pack 3; By the position of adjusted filter screen 3 and water fender 4, the ice content in the Ice Storage Tank of the left side can be regulated; Near cooling water outlet 7 place, tilt to install frozen water and be separated filter screen 5, it is miter angle that frozen water is separated filter screen 5 with ice-reserving cell wall 8 leg, forms double-filtration, effectively reduce the ice crystal amount of outflow with screen pack; Electric heater 6 is on cooling water outlet pipeline.
As shown in Figure 2, the mesh of screen pack 3 is herringbone, and width of mesh is 200 orders, only allows water to pass through, does not allow ice crystals to pass through.Screen pack 3 adopts stainless steel, and multilayer is arranged, realizes frozen water well and is separated.
When ice-reserving starts, screen pack is placed in the position being separated filter screen in Ice Storage Tank near frozen water, clash into ice-reserving cell wall 8 from subcooled water import 1 subcooled water out and remove supercooled state, forming ice crystal enters in Ice Storage Tank, be separated the two-stage separation of filter screen 5 through screen pack 3 with frozen water, ensure to enter in the water in cold water outlet pipeline not containing ice crystals.Cold water enters cold water outlet pipeline, and electric heater 6 automatically adjusts under the feedback of temperature control system, if cold water outlet pipeline temperature is lower than 0 DEG C, then electric heater 6 heats; If temperature reaches more than 0 DEG C, then stop heating, guarantee that the cold water water temperature entering circulatory system pipeline is all not less than 0 DEG C, eliminate supercooled state completely.
After ice-reserving process completes, the ice slurry of certain ice content is formed in Ice Storage Tank, now to regulate ice slurry ice content to adapt to the demand of air-conditioning system load, then arrive commitment positions by result of calculation moving filter net 3, water on the left of Ice Storage Tank will enter Ice Storage Tank right half part by screen pack 3, ice crystal stays Ice Storage Tank left-half, and then changes the ice slurry ice content of Ice Storage Tank left-half.Insert in draw-in groove 9 by water fender 4 again, support fixing screen pack 3, Ice Storage Tank is divided into left and right two parts simultaneously, the Ice Storage Tank left side forms the ice slurry of required ice content, and right-hand component can be used again, improves Ice Storage Tank utilization rate.
