The specific embodiment
See Fig. 1, a kind of pair of low-temperature receiver down-hole aircondition includes mechanical refrigeration module 1, the ice-reserving tank module 2 that is connected with mechanical refrigeration module 1, gas path module and the air-cooler module of releasing that is connected with gas path module is formed; Gas path module includes carbon dioxide liquid bottle 3, decompression hand valve 4, throttle part heat exchanger 5, heat exchanger 6, liquid-sighting glass 7 and first outgassing nonreturn valve 8, carbon dioxide liquid bottle 3 liquid outlets are successively by decompression hand valve 4, throttle part 5 is connected with heat exchanger 6 inlets, the connecting line of heat exchanger 6 gas outlets and first outgassing nonreturn valve 8 is provided with liquid-sighting glass 7, release the air-cooler module and include pneumatic blower fan 9, be arranged at the pressure regulator 10 at pneumatic blower fan 9 air inlet port places and be arranged at second outgassing nonreturn valve 11 that pneumatic blower fan 9 gas outlets are located, pneumatic blower fan 9 air inlet ports are connected with first outgassing nonreturn valve 8 by pressure regulator 10, and heat exchanger 6 and ice-reserving tank module 2 are set up in parallel in the sidepiece of pneumatic blower fan 9; Or heat exchanger 6 and ice-reserving tank module 2 are arranged side by side the sidepiece (see figure 2) in pneumatic blower fan 9, or pneumatic blower fan 9 is two and is connected in parallel, heat exchanger 6 is arranged at the sidepiece of a pneumatic blower fan 9a, and ice-reserving tank module 2 is arranged at the sidepiece (see figure 3) of another pneumatic blower fan 9b.
See Fig. 4, apparatus of the present invention gas path module has second kind of embodiment.When the carbon dioxide low-temperature receiver is Dewar jar 3a, owing to be pure carbon dioxide liquid in the Dewar jar 3a, so compressed air branch road pretrigger blower fan protection system need be set.The compressed air branch road includes tank of compressed air 3b, second decompression hand valve 4b and the 3rd outgassing nonreturn valve 8b, and is in parallel with former gas circuit module.
Under the ice-reserving operating mode, 1 work of mechanical refrigeration module provides cold to ice-reserving tank module 2, makes its cold-storage water freezing finish process of cool.The mode that cold is provided can be directly to flow through ice-reserving case sweat cooling by freon, or provides cold by the refrigerating medium mode.
See Fig. 1, Fig. 4, in the time of ice-reserving tank module 2 cold-storages, gas path module is started working: open decompression hand valve 4,4a, carbon dioxide liquid bottle 3, the 3a pressure inside is with in the carbon dioxide gas-liquid mixture ramming system pipeline, enter heat exchanger 6 heat exchange of vaporizing through throttle part 5, whether liquid-sighting glass 7 is used for observing carbon dioxide and vaporizes fully, as vaporize and not exclusively need regulate decompression hand valve 4,4a or throttle part 5, preventing air motor generation liquid hammer, the carbon dioxide after the vaporization enters the air-cooler modular belt blower fan work of taking offence of releasing through first breather check valve 8.The gas pressure of releasing in the air-cooler module is adjusted to pneumatic blower fan 9 work of setting value back drive through pressure regulator 10, the operating pressure that has guaranteed air motor is all the time in safe range, and the low-pressure tail gas of last pneumatic blower fan is through second outgassing nonreturn valve 11 and be discharged in the external environment.
When gas path module adopts second kind of embodiment, at first compressed air branch road work: the high pressure air among the tank of compressed air 3b is by the second decompression hand valve 4b step-down, compressed air after the step-down enters through the 3rd breather check valve 8b and releases the air-cooler module, the compressed air branch road is mainly used in the pretrigger of pneumatic blower fan 9, because what store among the Dewar jar 3a is the carbon dioxide neat liquid, suffering liquid hammer if directly use system pipeline the stifled or air motor of ice may occur, will be more safe and reliable and make pneumatic blower fan 9 pretriggers success back carbon dioxide liquid enter pipeline again by the compressed air branch road.
In the process of refrigerastion, outside air carries out the cooling first time by heat exchanger 6 earlier, carries out the cooling second time by ice-reserving case 2 again, is blown in the room environmental by pneumatic blower fan 9 at last.See Fig. 2, Fig. 3, or outside air lowers the temperature by heat exchanger 6 and ice-reserving case 2 respectively, be blown in the room environmental by pneumatic blower fan at last.
The utility model is being released under the cold operating mode, the cold of ice-reserving tank module 2 is by the blower fan auxiliary cooling, carbon dioxide plays the effect of auxiliary cooling through heat exchanger 6 vaporization heat absorptions simultaneously, its tail gas is used for driving pneumatic blower fan 9 continuous firings then, because carbon dioxide flow determines according to driving pneumatic blower fan 9 needed tolerance, so wholely release cold process source of the gas and be fully utilized.The carbon dioxide liquid bottle that the utility model adopts as long as filling amount is reasonable, just can take full advantage of in realizing putting the dual-use function that cold-peace drives blower fan, and its storage appearance ability also is greater than the pure compression air power source simultaneously.Second kind of scheme adopts the Dewar jar as the carbon dioxide low-temperature receiver, but one bottle of carbon dioxide Dewar jar liquid bottle storing liquid carbon dioxide 200kg that volume is 210L, and being converted into the gas volume that a normal atmosphere depresses is 102m
3, this just means that Dewar tank storage capacity is bigger, but uses the neat liquid carbon dioxide to need small amount of compression air pretrigger blower fan to come protection system as low-temperature receiver.So utilize under the identical time index liquid carbon dioxide as the blower fan apparatus devices needed volume of major impetus much smaller than the pure compression air power source.Because the liquid carbon dioxide vaporescence is by the heat exchanger evaporation and heat-exchange, its cold can effectively utilize in reducing environment temperature, so the total exchange capability of heat of equipment will obviously be better than equal ice-reserving amount, only use the ice-storage air-conditioning of compressed air-driven blower fan.Simultaneously liquid carbon dioxide can be at the ice-reserving low-temperature receiver because emergency situations back up separate refrigeration as low-temperature receiver can not normally use the time, eliminated the potential safety hazard that the accident such as undesired of powering causes.Ice-reserving tank module 2 configurable water purifying devices of the present utility model can be converted to ice-reserving water emergent water.
