Description

The coil pipe combining structure of accumulation of heat ice machine bin

The utility model relates to a kind of modular construction technology of the refrigerating plant of cold air and air-conditioning, it is a kind of coil pipe combining structure of accumulation of heat ice machine bin, especially refer to a kind of with upper and lower each layer of the coil pipe in ice machine bin gateway be made as two to go into, two outlet combination, and coil pipe is the new structure of arranging with opposite course, coiling alternately layer by layer.

When everybody was just enjoying comfortable pleasantly cool cold air and air-conditioning, the bulky equipment that adopts refrigerant condenser to carry out heat exchange consumed our energy just fast.Under the situation that the duration world population expands, the energy consumes day by day, how energy savings, effective use of energy sources are the targets that most of R﹠D work person makes great efforts.And the refrigerating and air conditioning technician also makes great efforts towards this target to advance, and expectation produces the target of high refrigerating capacity with minimum energy consumption, so the freezing or air-conditioning system of various different operative configuration is arisen at the historic moment.As utilize the load operation of carrying out refrigerant condenser with the ionization peak time night with ice storage, and both can utilize the night atmospheric temperature lowly to carry out heat exchange to reduce chilled load, raise the efficiency, and can low electricity price reaches the cost saving expenditure from the peak whereby; Again ice storage is dissolved to daytime and to carry out heat exchange with air conditioner and use with the supply cold air conditioner.And present existing a kind of heat accumulating type ice-storage air conditioning system, as shown in Figure 1, being mainly refrigerant condenser group 10 compresses refrigerant, the heat exchange cooling enters unit 11 bittern is cooled to required low temperature (below 0 ℃), squeeze into again in the ice machine bin 12, cooperate cooling coil with water freezing, at this moment, because of the brine temperature that absorbs heat that freezes raises slightly, and utilize water pump 13 that it is sent into cooling in the frozen water unit 11 again; So circulate in regular turn until water congeals into ice with ice machine bin 12; When desire is used air-conditioning cold air, then magnetic valve 14 is turned off, made low temperature bittern directly enter air-conditioning box 15 and carry out heat exchange, make the comfortable cool house effect of indoor tool; And bittern enters and utilizes molten ice to reduce the cold type that temperature continues on for air-conditioning box 15 in the ice machine bin 12 to produce the cold air effect.Shown in Fig. 2,3, be the internal structure schematic diagram and the generalized section of ice machine bin 12 among Fig. 1 of known technology, mainly be to have to be provided with the folded mutually coil pipe 122 of all multilayer layers in the groove of heat-insulation layer 121, utilize inlet tube 123 and outlet 124 to connect recirculated cooling water liquid and reach icing purpose gradually, because many coil pipes 122 of tool appropriate intervals are to adopt combination in the same way, promptly watch the arrival end of (as shown in Figure 2) all coil pipes 122 all to be positioned at inlet tube 123 sides from top to bottom and be connected with; When the bittern of low temperature after inlet tube 123 enters many coil pipes 122, unrolling in the groove inside turn absorbs the heat of water liquid and the exit 124 that arrives is gone out, and freezes gradually for 125 (as shown in Figure 3) along the external diameter of coil pipe 122 to reach water; So, the fastest with one deck coil pipe 122 its inlet tube 123 place's icing rates, slower to outlet 124 icing rates.So, quite inhomogeneous and speed is slow with regard to the freezing efficiency of whole ice machine bin 12, just expend many unnecessary energy virtually, do not reach the purpose of saving the energy.As shown in Figure 4, it is another known ice machine bin structure, the coil pipe 21 of the inlet tube 20 in this ice machine bin 2 is adopted interlace mode, be that ground floor (solid line is represented) is as spiraling clockwise, the second layer (chain-dotted line is represented) then adopts and spirals counterclockwise, its port of export is connected with outlet 3 again, the bittern that so constitutes each layer coil pipe 21 flows to opposite, make the icing thickness and the direction of each coil pipe 21, it no matter is the complementation that left and right directions or above-below direction all can be suitable, then no matter be present down consistent symmetrical or between the upper and lower wrong (as shown in Figure 5) all can make the gap 23 between each layers of ice 22 minimum, be that icing rate and speed all can significantly improve, reduce the horsepower load, save energy loss.But, if desire is saved the energy and is focused on that the emphasis that is only the saving energy with the speed that reaches cooling ahead of time that how to reduce pressure studies, then above-mentioned technology also has the further space of in-depth design, proposes a better design, can really reach the effect of saving the energy.

Main purpose of the present utility model is to provide a kind of coil pipe combining structure of accumulation of heat ice machine bin, borrow with the coil pipe in the ice machine bin be with opposite course, the setting of spiraling alternately layer by layer, cooperate each layer coil pipe to adopt the double exit and entrance compound mode that coil pipe is shortened by the distance of the outlet that enters the mouth again, allow the employed pressure of coil pipe reduce also and can shorten the time of freezing, make the bittern in the coil pipe really reach the loss that reduces working pressure and icing required time and reduce the energy.

The technical solution of the utility model and technical characterictic are: the coil pipe combining structure of this accumulation of heat ice machine bin, coil pipe in its ice machine bin be with opposite course layer by layer coiling mode alternately arrange, its each layer coil pipe is divided into two isometric coil pipes with its raw footage one, and respectively be provided with two inlet tubes, two outlets, and wherein one section coil pipe encloses in skin, this layer circle footpath is big, the number of turns is few, another section coil pipe encloses in internal layer, and its circle footpath is little, the number of turns is many, and these two coil lengths that are divided into two are identical.Cooperate each layer coil pipe to adopt the double exit and entrance compound mode that coil pipe is shortened by the distance of the outlet that enters the mouth again, allow the employed pressure of coil pipe reduce also and can shorten the time of freezing, make the bittern in the coil pipe really reach the loss that reduces working pressure and icing required time and reduce the energy.Allow the pressure of original use reduce relatively, make its effect that reaches step-down, improve bittern freezes in the coil pipe speed and effect relatively.

Remarkable advantage of the present utility model is that it compares with located by prior art, improves bittern freezes in the coil pipe speed and effect, reduces the pressure load of horsepower, realizes the real saving energy.
