Abstract
The utility model discloses an ice-storage water catcher for a vacuum cooling device. The ice-storage water catcher comprises a coil connected with a refrigerating unit, wherein both ends of the coil are sealed, water which can be frozen into ice to serve as a cool storage medium is encapsulated in the coil, and the coil is bent in a closely arranged planar spiral shape from inside to outside. The ice-storage water catcher for the vacuum cooling device in the utility model has high heat capacity, low dosage of the cool storage medium and little temperature fluctuation of the coil; and the ice-storage water catcher has the advantages of simple structure and high heat-transfer efficiency, is stable in operation and can be widely used in the vacuum cooling device.
Description
Technical field:
The utility model relates to the water vessel of refrigerating plant, particularly a kind of vacuum cooling unit water vessel of icing cool storage function that has.
Background technology:
The principle of vacuum cooled is by step-down the boiling point of water in the object to be reduced, thereby the heat of taking away object then in the explosive evaporation process is realized cooling rapidly.It has characteristics such as cooling velocity is fast, cooling effect is even, and can keep the freshness of fruits and vegetables, prolongs its shelf-life.At present, this technology obtains increasingly extensive application in fields such as agricultural product and food.
Water vapour coagulator is commonly called as " water vessel ", is the significant components of refrigerating plant.Vacuum cooling unit mainly is made up of vacuum processing chamber, vacuum system, refrigeration system and control system four major parts, and wherein refrigeration system comprises refrigeration unit and water vapour coagulator (water vessel).Because refrigeration duty changes greatly in whole vacuum cooled process; therefore use traditional metal coil pipe water vessel to appear at initial buck stage through regular meeting; the generation cooling ability is excessive, and in the moisture content explosive vaporization stage, cooling ability can't satisfy the situation of refrigeration duty again.This cooling ability and the unmatched situation of required refrigeration duty can influence the performance of whole vacuum cooling unit.
The utility model content:
Technical problem to be solved in the utility model is the defective that overcomes existing water vessel, and a kind of vacuum cooling unit ice-reserving water vessel is provided, and it can carry out cold-storage as medium with ice, thereby increases its thermal capacity, reaches the purpose of improving the water vessel operating efficiency.
The technical scheme in the invention for solving the technical problem is as follows:
A kind of vacuum cooling unit ice-reserving water vessel includes the coil pipe that is connected with refrigeration unit, this coil pipe closed at both ends and inner be packaged with can glaciation as the water of cool storage medium.
Vacuum cooling unit described in the utility model ice-reserving water vessel, its coil pipe are bent into the compact arranged planar spiral of circle circle from inside to outside.
To ice in the utility model course of work as cool storage medium, its coil pipe inside is packaged with water, in the vacuum cooled process, rely on cold that refrigeration unit produces will water congeals into ice to carry out cold-storage, in treating cold article during the moisture explosive vaporization, Ice storage coiled pipe is operated at full capacity, the cold of storage in the ice is discharged the whole steam of condensation.Because ice is temperature-resistant in melting process, therefore to compare with existing metal coil pipe water vessel, the temperature fluctuation of coil pipe is less.Adopt ice to be that as another advantage of cool storage medium the quality of required medium is less, if with vacuum cooling unit 300g water is cooled to 15 ℃ from 30 ℃ in 5min is example, the required cold that provides of refrigeration system is 63w by calculating as can be known, and then the quality of required ice is 56.25g in the water vessel; If adopt copper as cool storage medium, the quality of required copper is 3230g by calculating as can be known, is far longer than the quality of ice.Therefore, under the condition of equal quality cool storage medium, adopt after the Ice storage coiled pipe, vacuum cooling unit described in the utility model increases greatly with the thermal capacity of ice-reserving water vessel, thereby can more effectively stablize vacuum cooling unit at the initial buck stage and the matching state of cooling ability and required refrigeration duty in the moisture explosive vaporization stage.In addition, the coil pipe of compact arranged planar spiral has also increased coil lengths and heat exchange area, has improved the efficient of described ice-reserving water vessel.
In a word, vacuum cooling unit described in the utility model is less with ice-reserving water vessel thermal capacity amount big, required cool storage medium, the coil temperature fluctuation is little, have advantage simple in structure, stable and that heat exchanger effectiveness is high, can be widely used in vacuum cooling unit.
Description of drawings:
Fig. 1 is a structure diagram of the present utility model.
The specific embodiment:
Accompanying drawing 1 discloses a specific embodiment of the present utility model, now with accompanying drawing the utility model is described in conjunction with specific embodiments.
Vacuum cooling unit shown in Figure 1 includes coil pipe 1 with the ice-reserving water vessel, this coil pipe 1 is connected with refrigeration unit 2, its closed at both ends, and be bent into the compact arranged planar spiral of circle circle from inside to outside, thereby increased coil lengths and heat exchange area, this coil pipe 1 inside is packaged with water, the cold that relies on refrigeration unit 2 to produce, the water of this inside encapsulation can be frozen into ice as cool storage medium, so that the storage cold.
In the vacuum cooled process, at first open refrigeration unit 2, the water in the coil pipe 1 is freezed gradually, after water freeze all Cheng Bing, open vacuum system, along with vacuum indoor pressure reduces, treat the moisture start vaporizer in the cold article.In the initial decompression stage, the water vapour amount of evaporation is less, and this moment, the coil pipe 1 of ice-reserving can continue the cold that the absorption refrigeration unit produces simultaneously with the steam total condensation; Drop to when treating the pairing saturation pressure of cold article self-temperature at vacuum chamber pressure, treat that moisture begins explosive vaporization in the cold article, this moment, the coil pipe 1 of ice-reserving was operated at full capacity, and ice begins to melt released cold quantity, and water vapor condensation is got off.Because ice is temperature-resistant in melting process, so the temperature fluctuation of coil pipe is less.
Because the utility model adopts ice as cool storage medium, therefore the quality of required cool storage medium is less, and under the situation of cool storage medium mass conservation, vacuum cooling unit described in the utility model is bigger than the thermal capacity of conventional metals coil pipe water vessel with the ice-reserving water vessel.
Ice-storage water catcher for vacuum cooling device described in the utility model has advantage simple in structure, stable and that heat exchanger effectiveness is high, can be widely used in vacuum cooling unit.
