Description
Technical field
The present invention relates to technical field of central air, specifically, be related to a kind of chilled water storage system for special-shaped slot and
Method.
Background technology
Water cold storage technology is the sensible heat storage energy using water, has many advantages, such as low cost, stable, easy to maintain,
It is the effective means for solving air conditioning system increase-volume and " peak load shifting ".Water temperature natural layering method is the water due to different temperatures
Density contrast caused by natural layering of the water on gravity direction.In natural layered catch basin, cold water is gathered in water storage
The lower part of slot, hot water aggregate form the natural layering of hot water or cold water, in order to make water with gravity stream or piston on the top of catch basin
Quietly lead-in groove is interior or by being drawn in slot for levelling, appropriate water distributor is set in cold water import and export, to ensure current in water
It is evenly distributed in slot.
At present, natural layered cold-storage sink is due to its simple structure, convenient control, it has also become chilled water storage system is main
Application form, how problems faced mainly to inhibit the mixing of hot water or cold water, and it is more uniform to use stream, so as to reduce tiltedly
The thickness of warm layer improves cold storage efficiency.In order to reduce thermoclinic thickness, the cold storage efficiency of cold-storage sink is improved, it is often desirable that
There are one the catch basin of the high-aspect-ratio of regular shape, such as cylinder or cube shaped, but by place item in practical application
Part limitation can not often be built, and the depth of the even single each position of catch basin is different from sometimes, and the prior art is to such storage
The processing method of sink is as follows：The different catch basin physical separation of single depth into the identical catch basin of several depth, such as
The method, which not only adds cost, includes civil engineering and waterproof thermal-insulated etc., and due to wall and the thickness of thermal-insulating waterproof, makes
The dischargeable capacity for obtaining cold-storage sink is further reduced.
Water distributor is connected with top carry out water distribution, this side with return water supervisor with one group of vibration means for main pipe for supplying water in the bottom of catch basin
Method is the common practice of natural layered catch basin, has preferable water distribution effect for the identical catch basin of depth.But for
The different different in nature sink of depth uses such mode water distribution, and the energy storage efficiency of cold-storage sink is usually relatively low, and due to cross section
Variation so that the flowing velocity of water in sink is difficult to hold in vertical direction, have very big disturbance, part in the horizontal direction
Region forms recirculating zone, and the water of this part is not only let cool without participating in storing very well, and can expand mesolimnion, therefore accumulation of energy water
Slot it is less efficient.
The content of the invention
It is an object of the invention to provide a kind of chilled water storage systems for special-shaped sink, reduce cold-storage sink storage water and exist
The disturbance of horizontal direction in discharging cold course is stored, mesolimnion is thin, stable in outlet water temperature, and storage lets cool efficient.
Technical solution is used by chilled water storage system disclosed by the invention for special-shaped sink：One kind is used for special-shaped slot
Chilled water storage system, including handpiece Water Chilling Units, cold-storage sink, heat exchanger, cold-storage pump and let cool pump, the handpiece Water Chilling Units pass through cold-storage
It pumps as cold-storage sink cold-storage, the cold-storage sink is let cool by letting cool pump to heat exchanger, and the cold-storage sink is equipped with several differences
