Water-distributing device in a kind of thermal stratification type chilled water storage system
Technical field
the invention belongs to accumulation of energy field, relate to the water-distributing device in a kind of thermal stratification type chilled water storage system.
Background technology
water cold storage technology utilizes electricity price between peak and valley, is stored in water at low ebb rate period by cold, and the peak of power consumption period uses the cryogenic freezing water extraction stored cold for idle call by day.When air-conditioning service time and non-air-conditioning service time and electrical network peak and low ebb synchronous time, use when just the idle call electricity in electrical network rush hour can be transferred to electrical network low ebb, reach the object of power cost saving.The most ripe and the effective cold-storage mode of current use is natural layering.
natural layering and thermal stratification, thermal stratification type water cold storage utilizes water density when different temperatures this physical characteristic different, relies between density official post warm water and cold water and keep separating, and avoids cold water and warm water mixing to cause loss of refrigeration capacity.
the density of water about 4 DEG C time is maximum, and along with the high-density of water temperature reduces gradually, utilize this physical characteristic of water, the water making temperature low is stored in the bottom in pond, and the high water level of temperature is in the top being stored in pond.Design good thermal stratification type water cold storage pond and form a caloic switching layer between warm water district, top and cold water area, bottom.One stable and thickness is little caloic switching layer improves the key of cold-storage efficiency.
in order in cistern vertical direction cross section on, current are made to flow equably on whole section reposefully with gravity current or piston flow and import reposefully in pond (or drawing by pond), formed between warm water district, top and cold water area, bottom and keep effective, thickness is a little as far as possible caloic switching layer, key is that the top and the bottom in cistern arrange identical sprinkler, to guarantee that current meet Fo Lei get (Frande) coefficient when entering cistern, make uniform fluid flow distribute and disturbance minimally enters cold accumulating pond.The design and construction of sprinkler is the key technology of thermal stratification type water cold storage, and we are called usually, the water distribution technology of water cold storage.
water distribution technology is also known as steady flow, existing flow straightener generally enters cold accumulating pond by what install that check valve or some buffer gears with pooling feature make uniform fluid flow, although current flow straightener decreases the impulsive force of current, but current maldistribution, still have upset to a certain degree, make thermoclinic length sides large, cold consumption is aggravated.
