Abstract
The utility model relates to a diaphragm type energy accumulating water storing tank which comprises a water storing tank and two water passing openings. A watertight heat insulation diaphragm is arranged in the water storage tank, and thus, the stability of energy storage density and water supply temperature can be improved. The utility model is widely used for electric refrigeration, electric heating central air-conditioner systems or the technical refrigeration of the industries of brewing wine, medical preparation, dyeing print, textile, etc. Cold water or hot water generated in the time of an electrovalency trough can be stored and used in the time of an electrovalency peak. Producing and operating cost can be greatly reduced.
Description
The utility model belongs to water energy accumulating technique field, particularly a kind of diaphragm type accumulation of energy hopper.
From the running condition of China's electrical network in recent years, the electric load of peak times of power consumption and low power consumption phase not only exists gap, and more and more big.Along with the implementation of development of market economy and tou power price, the electric power of low power consumption phase is just becoming a kind of resource of cheapness and is being much accounted of gradually.This resource of development and utilization needs corresponding techniques, and the water energy accumulating technique is exactly wherein a kind of.The water energy accumulating technique is applied to electricity refrigeration or electricity heats in the central air-conditioning system, make the water outlet energy-storage air conditioner system, it is with electricity price required cold water or hot water peak period, produce and be stored in the accumulation of energy hopper at the electricity price low-valley interval, treat electricity price use peak period, thereby reach the purpose of the cheap low ebb phase electric power of development and utilization.The water energy accumulating technique also can be used in the process refrigeration of industries such as wine brewing, pharmacy, printing and dyeing, weaving, the cold water that the cheap electrical production of electricity price low-valley interval is come out is stored in the accumulation of energy hopper, treat electricity price use peak period, can significantly reduce and produce and over-the-road expense.The realization of above-mentioned water energy-storage system needs to build economic and practical accumulation of energy hopper.Improving the ratio of performance to price of accumulation of energy hopper, mainly is to realize by energy storage density that improves the accumulation of energy hopper and the cost that reduces the accumulation of energy hopper.When utilizing original water storage device (as fire cistern) to make thermal stratification formula accumulation of energy hopper into, because former water storage device complex geometry, often cause water distribution not good, there be uneven flowing in water in the water storage device, so that local convection and blending phenomenon occur, make water temperature cambic horizon (to call thermocline in the following text) thickening between high-temperature water and the water at low temperature, reach sometimes several meters thick, cause the energy storage density of whole hopper greatly to reduce.Simultaneously, above situation also causes the instability of supply water temperature, causes the decline of total system cooling or heating quality.
The purpose of this utility model is to provide a kind of diaphragm type accumulation of energy hopper, it can eliminate convection current and blending phenomenon between high-temperature water and the water at low temperature fully, make thermoclinic thickness less than 0.05 meter, thereby improve the energy storage density of hopper and the stability of supply water temperature.
The utility model is to be achieved through the following technical solutions: a kind of diaphragm type accumulation of energy hopper, comprise a hopper and two water in-out ports, and one to four layer of waterproof barrier film arranged in the hopper, it is characterized in that described barrier film is with thermal insulation layer.
Advantage of the present utility model is: no matter be accumulation of energy process or with can process, the upper and lower of barrier film exists the water of different temperatures simultaneously, because the existence of waterproof barrier film, convection current and blending between the water of two parts different temperatures have been stoped, again because the existence of thermal insulation layer, the interchange of heat of the water of two parts different temperatures significantly reduces, these two kinds of results that effect acts on simultaneously, make thermoclinic thickness less than 0.05 meter, thereby improved the stability of the energy storage density and the supply water temperature of hopper.
Further specified below in conjunction with drawings and Examples, but be not limited only to this.
Fig. 1 is an embodiment of the present utility model generalized section of (be used for the water cold-storage and fill cold latter stage).
This diaphragm type accumulation of energy hopper comprises a hopper [1] and two water in-out ports [2] [3], and two layers of waterproof barrier film [4] [5] are arranged in the hopper [1], and thermal insulation layer [6] is clipped between two layers of barrier film.
Fill when cold, the warm water on barrier film [4] top flows out from water in-out port [2], become the chilled water that to store through refrigeration and flow into barrier film [5] bottom through going out oral siphon [3], along with the increasing of barrier film [5] bottom chilled water volume and the minimizing of barrier film top warm water volume, move on the position of barrier film is continuous, in hopper, be full of till the chilled water.Because the existence of barrier film [4] [5], convection current and blending between the water of two parts different temperatures have been stoped, again because the existence of thermal insulation layer [6], the interchange of heat of the chilled water of the warm water on barrier film [4] top and barrier film [5] bottom significantly reduces, these two kinds of effects exist simultaneously, make thermoclinic thickness less than 0.05 meter, thereby improved the stability of the energy storage density and the supply water temperature of hopper.
Fig. 2 is another embodiment of the present utility model generalized section of (be used for the water cold-storage and use cold latter stage).
This diaphragm type accumulation of energy hopper comprises a hopper [1] and two water in-out ports [2] [3], and the waterproof barrier film of one deck [4] is arranged in the hopper [1], thermal insulation layer [6] be attached to barrier film [4] below.
Use when cold, the chilled water of thermal insulation layer [6] bottom flows out from water in-out port [3], through releasing cold warm water flows into barrier film [4] from water in-out port [2] the top that becomes, along with the minimizing of thermal insulation layer [6] bottom chilled water volume and the increasing of barrier film [4] top warm water volume, the position of barrier film constantly moves down, and chilled water uses until exhausted in hopper.Because the existence of barrier film [4], convection current and blending between the water of two parts different temperatures have been stoped, again because the existence of thermal insulation layer [6], the interchange of heat of the chilled water of the warm water on barrier film [4] top and thermal insulation layer [6] bottom significantly reduces, these two kinds of effects exist simultaneously, make thermoclinic thickness less than 0.05 meter, thereby improved the stability of the energy storage density and the supply water temperature of hopper.
