Abstract
The utility model relates to a carbon dioxide passive cooling air conditioner which is formed by a liquid inlet communicated with an air outlet through a first pressure-reducing valve and an evaporation heat exchange device in turn. The evaporation heat exchange device comprises more than two evaporators in serial connection. A second pressure-reducing valve is arranged between each two evaporators. More than two stages of evaporators with stop valves and pressure gages are used for reducing pressure and absorbing heat from liquid carbon dioxide; after the heat is absorbed, a pneumatic fan is driven by the gas carbon dioxide to accelerate heat circulation around the evaporators so as to realize passive cooling; the air conditioner can supply cold energy to equipment and personnel, under the inexistence of external power; and the carbon dioxide passive cooling air conditioner has the advantages of low use cost, safety in use, long service life, wide application scope, and the like.
Description
Technical field
The utility model relates to a kind of passive air-conditioning, is a kind of passive air-conditioning that utilizes carbon dioxide refrigeration specifically.
Background technology
Traditional refrigeration system all be adopt extrinsic motive Driven Compressor such as electric power or power-equipment to gaseous refrigerant compress, condensation liquefaction, throttling, evaporation expand and produce the transfer that cold is realized heat, generally needs to be equipped with equipment such as motor or engine, refrigeration compressor, condenser, expansion valve, evaporimeter, blower fan.When perhaps the power-equipment fault causes the extrinsic motive forfeiture when cutting off the power supply; Compressor can't start; Need to rely on the miscellaneous part of extrinsic motive also can't work, can't provide extrinsic motive or burst accident to cause loss of power, but still need refrigeration air-conditioner work under special circumstances during a period of time; Like the storage of the cooling of special instrumentation, weaponry, mine lifesaving appliance etc., existing refrigeration air-conditioner can't meet the demands.In some inflammable and explosive occasions, there is bigger potential safety hazard in the conventional refrigeration hot line job in addition.
Existing non-transformer air-conditioning refrigeration system can address the above problem well, is 200920350800.0 disclosed non-transformer formula unit air-conditionings like the patent No., adopts in the air accumulator and in evaporimeter, realizes refrigeration with the surrounding air heat exchange behind the liquid gas refrigerant release of pressure; Wherein refrigerant must be the liquid gas of cryogenic high pressure; Through behind temperature control valve and the expansion valve release of pressure directly by the evaporimeter heat exchange of absorbing heat rapidly, be prone in evaporimeter, produce pipeline and freeze, cause air-conditioning system to damage; Also power can't be provided normally to pneumatic blower fan simultaneously; The air-conditioning system running is unstable, fragile, and service life is short.
Summary of the invention
For absorbing heat rapidly, the liquid gas refrigerant that solves cryogenic high pressure in the prior art is prone to cause evaporator pipeline to freeze; Damage air-conditioning system; It is a kind of simple in structure that the deficiency that can't normally use, the utility model provide, and can for evaporimeter the heat absorption refrigerant be provided safely and steadly; Simultaneously for other refrigeration parts provide power, the carbon dioxide passive refrigeration air-conditioning of long service life.
The technical scheme that the utility model adopts is: a kind of carbon dioxide passive refrigeration air-conditioning; Be communicated with the gas outlet and form through first pressure-reducing valve, evaporation and heat-exchange device successively by inlet; It is characterized in that said evaporation and heat-exchange device comprises the evaporimeter more than two of serial connection, evaporimeter is provided with second pressure-reducing valve between any two.
Further, said inlet connects first pressure-reducing valve through first stop valve, first Pressure gauge successively; First pressure-reducing valve connects the evaporation and heat-exchange device through second Pressure gauge, second stop valve successively.
Again further, comprise also and the pneumatic blower fan of the corresponding setting of evaporimeter more than two that pneumatic blower fan is connected between last evaporimeter and gas outlet of two above evaporimeters, is provided with the 3rd Pressure gauge between pneumatic blower fan and above-mentioned last evaporimeter; Said pneumatic blower fan connects the gas outlet through the 3rd stop valve.
Liquid carbon dioxide flows in two above evaporimeters of evaporation and heat-exchange device through inlet successively; Make liquid carbon dioxide gasification multiple expansion put cold through multi-step pressure reductions such as first pressure-reducing valve, second pressure-reducing valves; Cooperate first and second Pressure gauge observation liquid carbon dioxide pressure and first and second stop valve Adjustment System internal pressure; Make liquid carbon dioxide fully heat absorption in two above evaporimeters of evaporation and heat-exchange device; Carbon dioxide drives pneumatic blower fan and is detected by the 3rd Pressure gauge and adjust its pressure, finally outside the space, is discharged through the gas outlet by the 3rd stop valve.
Compared with prior art, the utlity model has following advantage:
1, utilize the liquid carbon dioxide gasification that air-conditioning heat absorption institute chilling requirement is provided; And the carbon dioxide flooding blower fan of taking offence in gasification back accelerates the heat circulation, need not external electric power or power drive, can safety, the stable refrigeration; Do not receive service condition and ambient influnence, safe in utilization, the life-span is long;
2. be equipped with pressure-reducing valve before the evaporimeter more than two; Mode through multi-step pressure reduction; Effectively solve that rapid decompression is prone to produce dry ice blocking pipeline or valve member in the liquid carbon dioxide process,, help prolonging air-conditioning service life for pneumatic blower fan provides normal wind power; Improve the utilization rate of liquid carbon dioxide simultaneously, reduce the operation of air conditioner cost;
3. the pressure of a plurality of Pressure gauge monitoring each several parts is set, further the safety assurance ability of raising equipment operation.
The utility model is through having stop valve, manometric evaporimeter with liquid carbon dioxide decompression heat absorption more than the two-stage; Cooperate heat absorption back carbon dioxide to drive the circulation of pneumatic blower fan quickening evaporimeter ambient heat and realize passive refrigeration; This air-conditioning can not have under the situation of extrinsic motive for equipment and personnel provide cold, has that use cost is low, safe in utilization, a long service life, advantage such as applied widely.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: inlet 1, the first stop valve 2, the first Pressure gauges 3, the first pressure-reducing valves 4, the second Pressure gauges 5, second stop valve, 6, the first evaporimeters, 7, the second pressure-reducing valves, 8, the second evaporimeters, 9, the three Pressure gauges 10, pneumatic blower fan 11, the three stop valves 12, gas outlet 13.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
