Description

Water-distributing device in a kind of chilled water storage system

Technical field

the invention belongs to accumulation of energy field, relate to the water-distributing device in a kind of chilled water storage system.

Background technology

water Cool Storage Technology utilizes electricity price between peak and valley, in the low ebb electricity price period, cold is stored in water, and the peak of power consumption period is used the cryogenic freezing water extraction storing cold for idle call by day.In the time that air-conditioning service time and non-air-conditioning service time and electrical network peak and low ebb are synchronizeed, just the idle call electric weight in electrical network rush hour can be transferred to electrical network low ebb time, use, reach the object of power cost saving.Using at present the most ripe and effective cold-storage mode is natural layering.

natural layering is thermal stratification, and thermal stratification type water cold-storage is to utilize different these physical characteristics of water density in the time of different temperatures, relies between density official post warm water and cold water and keeps separating, and avoids cold water and warm water to mix and causes loss of refrigeration capacity.

the density maximum of water in the time of 4 DEG C of left and right, along with the rising density of water temperature reduces gradually, utilizes this physical characteristic of water, makes water that temperature is low be stored in the bottom in pond, and the high water level of temperature is in the top that is stored in pond.Design good thermal stratification type water cold accumulating pond and between warm water district, top and cold water area, bottom, form a caloic exchange floor.A caloic exchange layer stable and that thickness is little is the key that improves cold-storage efficiency.

on cross section for vertical direction in cold accumulating pond, make current on whole section, flow equably reposefully and import reposefully (or drawing in by pond) in pond with gravity current or piston flow, between warm water district, top and cold water area, bottom, form and keep the caloic that effective, thickness is as far as possible little to exchange floor, key is that the top and the bottom in cold accumulating pond arrange identical sprinkler, to guarantee that current meet Fo Lei get (Frande) coefficient in the time entering cold accumulating pond, make current uniform distribution and disturbance minimally enter cold accumulating pond.The design and construction of sprinkler is the key technology of thermal stratification type water cold-storage, and we are called conventionally, the water distribution technology of water cold-storage.

water distribution technology claims again steady flow, existing constant-current stabilizer generally makes current enter uniformly cold accumulating pond by installation check valve or some with the buffer gear of pooling feature, although current constant-current stabilizer has reduced the impulsive force of current, but current maldistribution, still have upset to a certain degree, make thermoclinic length become large, make cold consumption aggravation.

Summary of the invention

the object of the invention is for the above-mentioned problems in the prior art, water-distributing device in a kind of chilled water storage system is provided, water-distributing device water distribution in this chilled water storage system is effective, structural design is ingenious, water outlet is evenly slow, solved the water-distributing device current maldistribution in existing chilled water storage system, flow velocity is too fast, can significantly upset mesolimnion and cause the problems such as cold consumption.

object of the present invention can realize by following technical proposal: the water-distributing device in a kind of chilled water storage system, described chilled water storage system comprises cold accumulating pond, it is characterized in that: described water-distributing device comprises and is the trapezoidal and inner shell for cavity, described shell top is water inlet end, described shell bottom has several limbers one, described shell bottom is communicated with described cold accumulating pond, in described shell, there is the sponge trapezoidal with being of matching of described shell shape, the bottom of described sponge is resisted against the bottom of described shell, the top of described sponge has rounded weather board, described weather board is connected on the inwall of described shell, on described weather board, there is several limbers two, described weather board top has buffer unit, described buffer unit comprises a buffer board, described buffer board be positioned at described shell water inlet end port under and on described buffer board, there are several limbers three, between described buffer board and described outer casing inner wall, there is gap, described buffer board is connected in described shell.
