Embodiment
Referring to the drawings 1, the utility model ice-melt water system includes end to end Ice Storage Tank 2, the and of variable frequency pump 1 successively
With cold end 5, variable frequency pump 1 is connected between the intake pipe 4 of Ice Storage Tank 2 and the entrance with cold end 5, the return pipe 3 of Ice Storage Tank 2 with
Connected with the outlet of cold end 5.The intake pipe 4 of Ice Storage Tank is arranged in ice-reserving trench bottom, and return pipe 3 is arranged in Ice Storage Tank top.
In order to realize the constant controllable of water temperature, set on one side between the outlet in variable frequency pump 1 and the outlet with cold end 5

Temperature sensor 7, pressure sensor 6, i.e. temperature sensor 7 and pressure sensor 6 is set between connecing to be arranged at cold end 5
Entrance before；Diaphragm pressure stabilization pot 8, i.e. barrier film voltage stabilizing are set between the outlet of variable frequency pump 1 and bypass pipe and supervisor junction
Tank 8 is arranged on the outlet port of variable frequency pump 1.The effect of diaphragm pressure stabilization pot 8 is to buffer the pressure oscillation in pump outlet tube road,
When the pressure in exit of pump pipeline has the fuctuation within a narrow range in permissible range, diaphragm pressure stabilization pot adjusts energy by the pressure of itself
Power absorptive amplitude, so as to avoid variable frequency pump from frequently frequency regulation or unlatching occur, stop.
In system described in the utility model, there is frozen water mixture well prepared in advance in Ice Storage Tank 2, its temperature is approached
0℃.Because water at low temperature is intended to sink, therefore water at low temperature is taken out by being arranged in the intake pipe 4 of the bottom of Ice Storage Tank 2, by frequency conversion
Water pump 1 is transported to cold end 5, with cold end 5 with exchanged heat by cooling article after temperature raise, then along being arranged in Ice Storage Tank
The return pipe 3 at 2 tops is returned to inside Ice Storage Tank 2, and from the top spray of Ice Storage Tank 2 to ice sheet therein.By high-temperature tempering
After contact heat-exchanging between ice, a part of ice-out, high-temperature tempering is then cooled back less than 2 DEG C again, then again by water intaking
Pipe 4 is exported, and circulates cooling.
When ice content is smaller or load fluctuation of with cold end 5 is larger (the such as refrigeration duty of increase suddenly) in Ice Storage Tank 2
When, return to the high-temperature tempering in Ice Storage Tank 2 and have little time to carry out sufficient heat exchange with ice, so as to cause into the low of intake pipe 4
Warm supply water temperature is increased over target cooling temperature, it is impossible to meet the cold process requirements of production.The utility model passes through cloth
Put the temperature sensor before with cold-side inlet 7 and sense water supply water temperature therein；And the aperture size of regulating valve 9 can be adjusted freely
Section, the direction of its regulation and amplitude determine by the water temperature parameters that temperature sensor 7 is sensed.When temperature sensor 7 is sensed
Water temperature be higher than target supply water temperature (such as 2 DEG C) when, the aperture of the regulating valve 9 being arranged on bypass pipe 10 then increases, now
Bypass flow increases, and is reduced with the return-enclosure coolant-temperature gage after mutually being mixed with the high-temperature tempering of cold end 5 is come from by bypass flow, returns
Groove water-carrying capacity also increases, and Ice Storage Tank tube internal heat exchange coefficient enhancing, the return-enclosure water with lower temperature is quickly reduced to less than 2 DEG C,
Water intaking temperature into intake pipe 4 falls back to target supply water temperature immediately；When the water temperature that temperature sensor 7 is sensed is less than target
During supply water temperature (such as 2 DEG C), reduce the aperture of regulating valve 9, now return-enclosure water temperature is raised, return-enclosure water-carrying capacity is also reduced, ice-reserving
Groove tube internal heat exchange coefficient is weakened, and the water intaking temperature into intake pipe 4 goes back up to target supply water temperature immediately.Thus achieve Ice Storage Tank
2 to the constant ice-melt water supply target of low temperature with cold end 5.
On the other hand, may be made up of some cold heat transmission equipments with cold end 5, its use time and the quantity to chilled water
Demand is different.The utility model patent realizes that the control of variable-flow, i.e. variable frequency pump 1 can be with by the way of variable frequency pump
By freely change input power frequency and regulating water flow, the regulation direction of water-carrying capacity and amplitude are felt by pressure sensor 6
The pressure of supply water parameter determination of survey.It is arranged on and senses pressure of supply water in real time with the pressure sensor 6 before the entrance of cold end 5, works as pressure
When the pressure of supply water that sensor 6 is sensed is higher than target pressure of supply water, show to be closed or reduced with the part heat transmission equipment of cold end 5
Chilled-water flow, with refrigeration duty reduction, now then reduces the running frequency of variable frequency pump 1 so that pressure of supply water falls back to mesh
Mark pressure of supply water value, variable frequency pump 1 it also avoid unnecessary power wastage.For still using cold end heat transmission equipment in operation,
Because pressure of supply water is constant, its chilled-water flow and semen donors are unaffected.When the pressure of supply water that pressure sensor 6 is sensed
During less than target pressure of supply water, show to open part heat transmission equipment with the increase of cold end 5 or increase chilled-water flow, born with cold
Lotus increases, and now then increases the running frequency of variable frequency pump 1 so that pressure of supply water falls back to target pressure of supply water value, it is ensured that
It is all be currently running be obtained in that specified chilled-water flow with cold heat exchanger.
In order to prevent because the rapid fluctuations of water flow pressure in pipeline cause variable frequency pump 1, frequently regulating frequency is frequently even
Open, shut down, diaphragm pressure stabilization pot 8 is set in the position exported close to variable frequency pump 1.Because diaphragm pressure stabilization pot 8 can be in certain model
Enclose the fuctuation within a narrow range of interior absorption pressure at any time so that the stabilization of pressure can be maintained in the pipeline being attached thereto in certain limit.
Therefore, when occurring small size pressure oscillation in pipeline, the pressure that pressure sensor 6 is sensed be similar to not change (or
Excursion is within the sensitivity that the initiation culture of variable frequency pump 1 is adjusted), now variable frequency pump 1 will not occur frequently frequency
Regulation, and also achieve constant target with the pressure of supply water of cold end 5.
