Description
Technical field
The present invention relates to cold-storage device technical field.
Background technology
Water cool storage air conditioning technology is as a kind of technology of utilizing the sensible heat of water to carry out cold storage: (night is when electrical network low ebb not needing cold or need the less time period of cold, simultaneously also air conditioner load low ebb) utilize refrigeration plant to prepare water at low temperature to store, then or technique cold in idle call with cold peak period (, being also air conditioner load peak conventionally) when on electrical network on daytime the peak to satisfy the demands.As a kind of effective way of electric power peak load shifting, the effect that can play economical operation, energy-conserving and environment-protective, is widely used, but how to reduce in actual applications taking up room of water cold-storage cell body, reduce cold-storage loss, improve the utilization ratio particular importance that seems.
Current Cool Storage Technology mainly adopts double flute or multi-groove type, labyrinth type, and single groove diaphragm type, single groove thermal stratification formulas etc. are several.Dual grooved always has a cell body not to be utilized, and space availability ratio is low; The operation of multi-groove type system needs multiple valves to switch, system complex, and it is large that difficulty is controlled in operation; Labyrinth type water flow velocity is wayward, easily forms whirlpool or short circuit and forms dead band, has in addition the shortcomings such as the cold warm water of part mixes, and water resistance is larger; Single groove diaphragm type septation constantly draws high up and down, and to having relatively high expectations of film, practicality is low; Generally use at present single groove thermal stratification formula, mainly utilize water density maximum in the time of 4 DEG C, utilize the phenomenon of appearance " cold lower part and hot upper part " without stirring in the situation that to carry out natural temperature layering cold-storage, but need accurately design, construction, ensure that thermoclinic thickness is as much as possible little, to improve cold-storage efficiency, and cold-storage temperature is minimum is not less than 4 DEG C.
Summary of the invention
The present invention is low in order to solve dual grooved water cold-storage space availability ratio; Labyrinth type water cold-storage flow resistance is large, cold-storage efficiency is lower; Multi-groove type cold accumulation system complexity, it is large that difficulty is controlled in operation; Single groove diaphragm type cold-storage practicality is low; Single groove thermal stratification formula mesolimnion control difficulty is large, cold-storage efficiency is low and cold-storage temperature is minimum is not less than the problems such as 4 DEG C.
For realizing above object, the present invention has taked following technical scheme: the large temperature difference water cold accumulation device of a kind of spiral fashion, comprise the cold-storage water pot or the cold-storage tank that include central principal axis, on it, be respectively equipped with the cold water inlet of the cold delivery port of cold-storage water inlet/release and cold-storage delivery port/release, in described cold-storage water pot or cold-storage tank, establish spiral fashion separation structure, described spiral fashion separation structure is made up of waterproof thermal-insulated separator, waterproof thermal-insulated separator is along the central principal axis rising of spiraling, in waterproof thermal-insulated separator, edge is connected with central principal axis, outer is connected with cold-storage water pot or cold-storage inboard wall of cistern, described waterproof thermal-insulated separator is separated to form continuous helical flow path at cold-storage water pot or cold-storage tank inner space, concrete is, the outer wall of helical flow path is the internal face of cold-storage water pot or cold-storage tank, the inwall of helical flow path is the outside wall surface of central principal axis, enclosure space between the internal face of cold-storage water pot or cold-storage tank and the outside wall surface of central principal axis forms helical flow path, this helical flow path one end and cold-storage water inlet/release cold delivery port to communicate, the other end and cold-storage delivery port/release cold water inlet to communicate.
Adopt water-proof heat-insulation material to make spiral and separate, screw on liter along circular water pot central principal axis steering wheel, in demarcation strip, along being connected with central principal axis, outer is connected with tank body, and the inside of tank body forms a continuous helical flow path.At cold-storage/release in cold process, separate and stop cold warm water directly to mix due to waterproof and heat-insulating, along helical flow path direction, only there is the direct contact heat transfer of cold warm water in segment runner, reduce the thermoclinic energy dissipation causing.Along with cold-storage/release the carrying out of cold process, only there are all the time adjacent two runners by the slow heat transfer of separating; After cold-storage finishes, in tank, water temperature is consistent, only has tank body heat transfer loss.In whole cold-storage, storage, dispose procedure, loss is less.
According to size and the economic water flow velocity of cold-storage/release cold energy power, determine the spacing of separating spiral plate in waterproof thermal-insulated separator, and ensure that the sectional area of helical flow path equates; According to cold-storage temperature extent and cold-storage efficiency, determine the progression of spiral demarcation strip.
Realize cold-storage owing to not relying on thermal stratification, can break through the lower limit of 4 DEG C of layering cold-storage water temperatures, further reduce cold-storage water temperature, improve the retaining temperature difference, reduce the volume of cold-storage cell body.
Owing to there is no the requirement of thermal stratification, there is no the restriction of flow stability, can cancel the water-locator in thermal stratification method.Reduce the idle space that in thermal stratification method, water-locator takies simultaneously, improved unit volume storage density of cold.
Owing to there is no the requirement of thermal stratification, water pot is without vertical installation, can be horizontal, inclination, buried installation, and avoid part to build requirement attractive in appearance, reduce the specially treated requirement to water pot basis.
Owing to there is no the requirement of thermal stratification, the requirement of the ratio of height to diameter of cold-storage water pot reduces, and can adapt to cold storage capacity less, the occasion that water pot is less.
The little water pot series, parallel operation that this invention water pot can be made enclosed, realizes the random combination of various cold-storage capacity.
Due to spiral structure, without " stagnant water " district, do not form whirlpool, and can reduce flow resistance, reduce the pump consumption of circulating pump.
The present invention compared with prior art, tool has the following advantages: the present invention relates to a kind of separation structure that spirals that is applied to large temperature difference water cold accumulation device, be separated to form helical flow path by spiral fashion, in cold-storage/release cold process, only there are two adjacent channels to have different transfer of heat, cold warm water contact heat transfer reduces, and can realize large temperature difference cold-storage, this is the device of a kind of effective raising storage density of cold and efficiency.
