Abstract
The utility model refers a high super cooling degree type super cooling unit used for the super cooling water dynamic ice producing system of an ice cold storage air conditioner, which comprises a metal inner tube and a metal outer tube, wherein the inner tube is sheathed in the outer tube; the two blind ends of the outer tube and the inner tube are provided with a coolant inlet and a coolant outlet. Both ends of the inner tube are a water inlet and a water outlet. The structural characteristic is that the inner wall surface of the inner tube is covered by a layer of a dielectric layer with lower or lowest non freezing temperature. The dielectric layer is made of PTFE, PF resin and other polymer materials. Compared with the prior art, the utility model can make the water reach a higher super cooling degree at the outlet of the super cooling unit, and enhance the ice-making rate and the energy efficiency of the entire ice producing system.
Description
The utility model relates to the subcooler that is used for ice-storage air-conditioning dynamic freezing of supercooled water system.
Adopting dynamic freezing of supercooled water in the existing ice-storage air-conditioning is a kind of new ice making mode.Compare with traditional static ice making mode, because the heat transfer resistance between refrigerant and the water is less, and can not increase along with the increase of making the ice amount, so reduced the certain energy loss.The dynamic freezing of supercooled water flow process is: water is cooled to supercooled state in subcooler, and water temperature is lower than 0 ℃.Eliminate its supercooled state through the supercooling arrester then, become mixture of ice and water, enter the ice storage jar.Ice in the mixture of ice and water is left in the ice storage jar, and water is separated, and enters subcooler again and circulates.The key technology of this kind dynamic freezing of supercooled water is to guarantee that subcooler does not take place) the east knot.In order to guarantee that subcooler does not freeze, the water that enters in the subcooler must be forbidden to carry secretly any ice crystal.In addition, the surface temperature that contacts with supercooled water in the subcooler must be not less than this surperficial lowest non-freezing temperature.In the Japanese used same device, the Facing material that contacts with water in the subcooler is common metal materials such as copper, aluminium, iron or stainless steel at present.Use the shortcoming of this class device to be, because its surperficial lowest non-freezing temperature is higher, generally more than-6 ℃, thereby water is difficult to obtain bigger temperature and falls in subcooler, be difficult to the degree of supercooling that reaches higher in subcooler outlet, make whole system be difficult to improve ice making rate and energy efficiency.
In order to overcome the shortcoming that exists in the above-mentioned prior art, the purpose of this utility model provides a kind of high supercooling degree subcooler that is used for ice-storage air-conditioning dynamic freezing of supercooled water system.Use it, water can obtain bigger temperature and fall in subcooler, can reach higher degree of supercooling in the subcooler outlet, improves the ice making rate and the energy efficiency of whole ice-making system.
In order to reach above-mentioned goal of the invention, technical solutions of the utility model are: be used for the high supercooling degree subcooler of ice-storage air-conditioning dynamic freezing of supercooled water system, comprise interior pipe and the outer tube made with metal material.Interior pipe box is contained among the outer tube.Outer tube and interior pipe two blind ends are provided with refrigerant import and refrigerant exit.Interior pipe two ends are water inlet and delivery port.Its design feature is that the inner wall surface of described interior pipe covers the dielectric layer that one deck has lower lowest non-freezing temperature.
According to above-mentioned technical scheme, described dielectric layer uses between polytetrafluoroethylene (PTFE), phenolic resins and other macromolecular material and their the similar different cultivars or presses the macromolecular material that different proportion mixes between different classes of.
Since the inner tube wall surface coverage that contacts with water in the utility model subcooler one deck by the dielectric layer that macromolecular material forms, its surperficial lowest non-freezing temperature is significantly reduced.Lowest non-freezing temperature as ptfe surface can be low to moderate-12 ℃, and the lowest non-freezing temperature on phenolic resins surface can be low to moderate-10 ℃.Therefore, the water in the subcooler does not freeze in the time of can reaching lower temperature on the surface that contacts with water, and water can obtain bigger temperature and fall in subcooler, and water can reach higher degree of supercooling in the subcooler outlet.Thereby the ice making rate and the energy efficiency of whole dynamic ice-making system are improved greatly.Compare with prior art, the utility model structure is almost constant, and manufacturing cost increases few, just can improve the technical indicator and the serviceability of same device greatly.
Below in conjunction with accompanying drawing and concrete embodiment the utility model is further described.
Accompanying drawing is a theory structure cutaway view of the present utility model.
Referring to accompanying drawing, the utility model subcooler comprises uses metal material, and as interior pipe 2 and outer tube 1 that copper, aluminium, iron or stainless steel etc. are made, interior pipe 2 is sleeved among the outer tube 1.Outer tube 1 is provided with refrigerant import 7 and refrigerant exit 5 with 2 liang of blind ends of interior pipe.Interior pipe 2 two ends are water inlet 4 and delivery port 6.The inner wall surface of interior pipe 2 covers the dielectric layer 3 that one deck has lower lowest non-freezing temperature.The material of dielectric layer 3 can use between polytetrafluoroethylene (PTFE), phenolic resins or other macromolecular material and their the similar different cultivars, press the macromolecular material that different proportion mixes between different classes of, and its thickness is 20-100 μ m.
Use of the present utility model, identical with prior art, do not repeat them here.What be worth proposition is that according to above-mentioned technical scheme, every surface coverage that contacts with water in existing cooler has one deck macromolecular material, can make water obtain bigger temperature in subcooler and fall, and reaches higher degree of supercooling in the subcooler outlet.Such as the technical scheme of a class, all belong to protection domain of the present utility model.
