In figure, gas reservoir (1), the first control valve (2.1), refrigeration machine (3), storage tank (4), the second control valve (2.2), pump (5), vacuum tank (6), valve (7).
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail.
As it is shown in figure 1, the utility model discloses a kind of fluctuation entrance heat-exchange system, including: gas reservoir (1), the first control valve 2.1, refrigeration machine 3, storage tank 4, second control valve 2.2;Wherein gas reservoir the 1, first control valve 2.1, refrigeration machine 3, storage tank 4, second control valve 2.2 and are sequentially connected.
The method of the fluctuation entrance heat exchange of system described in the utility model, comprises the following steps:
1) gas flows out through gas reservoir 1, controls dynamically regulating of valve 2.2 by controlling valve 2.1 and second to first, makes the flow of air-flow, pressure produce fluctuation;
2) fluctuation air-flow entrance refrigeration machine 3 condenses, and condensed gas-liquid two-phase material enters storage tank 4;
3) uncondensed gas in storage tank 4 is discharged by the second control valve 2.2.
When the second control valve 2.2 is normally opened, the first adjustment controlling valve 2.1 is only capable of regulating the flow of the air-flow entering refrigeration machine 3.
As in figure 2 it is shown, according to one preferred embodiment of this utility model, described fluctuation entrance heat-exchange system also includes pump 5, and the gas outlet of storage tank 4 is connected with pump 5, and pump 5 is connected with the gas access of gas reservoir 1.
The method of the fluctuation entrance heat exchange of this utility model preferred embodiment, comprises the following steps:
1) gas flows out through gas reservoir 1, controls dynamically regulating of valve 2.2 by controlling valve 2.1 and second to first, makes the flow of air-flow, pressure produce fluctuation;
2) fluctuation air-flow entrance refrigeration machine 3 condenses, and condensed gas-liquid two-phase material enters storage tank 4;
3) uncondensed gas in storage tank 4 returns to storage tank 1 by the second control valve 2.2 and pump 5.
As it is shown on figure 3, according to one preferred embodiment of this utility model, described fluctuation entrance heat-exchange system also includes vacuum tank 6 and valve 7;The gas outlet of described storage tank 4 and pump 5, vacuum tank 6, valve 7 are sequentially connected, and the entrance that valve 7 exports with refrigeration machine 3 is connected.
The method of the fluctuation entrance heat exchange of described fluctuation entrance heat-exchange system, comprises the following steps:
1) gas flows out through gas reservoir 1, controls dynamically regulating of valve 2.2 by controlling valve 2.1 and second to first, makes the flow of air-flow, pressure produce fluctuation;
2) fluctuation air-flow entrance refrigeration machine 3 condenses, and condensed gas-liquid two-phase material enters storage tank 4;
3) uncondensed gas in storage tank 4 is again introduced into refrigeration machine condensation by the second control valve 2.2, pump 5, vacuum tank 6, valve 7.
The static adjustment of valve 2.2 is controlled, it is possible to the pressure of the gas condensation that controls to be in refrigeration machine and flow by controlling valve 2.1 and second to first.
Work process of the present utility model is as follows:
Gas in gas reservoir flows out from gas outlet, by the dynamic adjustment in system two control valves, the flow of air-flow in pipeline, pressure is made to produce fluctuation, to improve cooling energy recovery, the air-flow of fluctuation flows into refrigeration machine condensation, condensed fluid storage in storage tank, uncooled gas let-down vessel.When the second control valve is normally opened, the first adjustment controlling valve is only capable of regulating the flow of the air-flow entering refrigeration machine.Meanwhile, uncooled gas can also pass through to be pumped back among gas reservoir, reenters condensing circuit, it is also possible to after pump and vacuum tank voltage stabilizing, be directly entered refrigeration machine and again condense.Can also by the pressure of the condensation that is in refrigeration machine to the static regulable control of two control valves gas and flow in condensation heat exchange system.
This utility model adds two control valves in traditional gas condensation heat exchange system, by the dynamic adjustment controlling valve, making the flow of the air-flow of entrance refrigeration machine, pressure produce fluctuation, improve cooling energy recovery, improve condensation efficiency.
