Abstract
The utility model discloses a joint-type rescue capsule air cooling system which comprises a liquid carbon dioxide cooling system, a throttle expansion cooling system and an evaporating cooling system. The liquid carbon dioxide cooling system, the throttle expansion cooling system and the evaporating cooling system are connected to form a joint cooling system through pipelines. Liquid carbon dioxide, liquid nitrogen, Freon or other working media are gasified to absorb heat and generate high pressure. The pressure difference between the hight pressure and the barometric pressure produces the Joule-Thomson cooling effect. After throttle expansion, gas carbon dioxide with relatively low humidity produces an evaporating and cooling effect. Latent heat of the liquid carbon dioxide and pressure energy produced in gasifying of the liquid carbon dioxide and the relatively low humidity are fully utilized to greatly improve cooling quantity of liquid carbon dioxide per weight unit. Under the condition that environment temperature of a capsule is met, quantity of stored liquid carbon dioxide is reduced and a space inside the capsule is saved.

Technical field
The utility model relates to the air conditioner refrigerating technical field, particularly a kind of air cooling system for survival capsule.
Background technology
When disastrous accident occured under the mine, the air cooling system of survival capsule can provide essential existence temperature for the miner who hides in survival capsule, made that the environment environment temperature maintains below 30 ℃ in the cabin, substantially satisfied the human survival requirement.The described ejector refrigeration system of Chinese patent ZL200910248593.2 is a kind of take liquid carbon dioxide as working fluid, and water is cold-producing medium, the open refrigeration system of frozen-free device.This patent of invention takes full advantage of the latent heat of liquid carbon dioxide and the pressure energy after its gasification in theory, improved the refrigerating capacity of unit mass liquid carbon dioxide, produce good refrigeration, reduce the memory space of liquid carbon dioxide, save the space in the cabin.But in the running of reality, the refrigeration of this system is unsatisfactory, and refrigerating efficiency is low, can not satisfy the demand.
Summary of the invention
The problems referred to above that exist for solving prior art, the utility model will design a kind of air cooling system that is used for survival capsule that can improve refrigeration.
To achieve these goals, the technical solution of the utility model is as follows: a kind of association type survival capsule air cooling system, comprise liquid carbon dioxide refrigeration system, throttling expansion refrigeration system and evaporative cooling system, described liquid carbon dioxide refrigeration system, throttling expansion refrigeration system and evaporative cooling system connect into combined refrigeration system by pipeline; Described liquid carbon dioxide system comprises hydrocone type liquid carbon dioxide liquid storage bottle, evaporation coil, described hydrocone type liquid carbon dioxide liquid storage bottle has a plurality of and parallel with one another connecting, and described hydrocone type liquid carbon dioxide liquid storage bottle is connected nozzle with evaporation coil successively by pipeline and is connected with the throttling expansion refrigeration system; Described throttling expansion refrigeration system comprises nozzle, expansion space and heat exchanger, and described nozzle is installed in inside, expansion space, connects with pipeline between expansion space and the heat exchanger, and described heat exchanger exit is connected with evaporative cooling system; Described evaporative cooling system is comprised of the indirect evaporative cooling device; Described nozzle utilizes the high pressure and the pressure reduction between the atmospheric pressure that produce after the working medium gasification heat absorptions such as liquid carbon dioxide, liquid nitrogen or freon to produce joule-thomson refrigeration effect; The gaseous carbon dioxide that described devaporizer utilization relative humidity after throttling expansion is lower produces heatcooling effect.
Compared with prior art, the utlity model has following beneficial effect:
Because being used for the air cooling system of survival capsule in the utility model is a refrigeration system that is constituted jointly by liquid carbon dioxide refrigeration system, throttling expansion refrigeration system and evaporative cooling system, take full advantage of latent heat, the pressure energy after the gasification and the lower relative humidity of liquid carbon dioxide, significantly improved the refrigerating capacity of unit mass liquid carbon dioxide.In the situation that satisfies the compartment environment temperature, reduce the memory space of liquid carbon dioxide, save the space in the cabin.
Description of drawings
The utility model is 1 of drawings attached only, wherein:
Fig. 1 is a kind of structural representation of association type survival capsule air cooling system.
Among the figure: 1, hydrocone type liquid carbon dioxide liquid storage bottle, 2, evaporation coil, 3, nozzle, 4, the expansion space, 5, heat exchanger, 6, devaporizer.
The specific embodiment
By following embodiment the utility model is further elaborated.As shown in Figure 1, a kind of association type survival capsule air cooling system, comprise liquid carbon dioxide refrigeration system, throttling expansion refrigeration system and evaporative cooling system, described liquid carbon dioxide refrigeration system, throttling expansion refrigeration system and evaporative cooling system connect into combined refrigeration system by pipeline; Described liquid carbon dioxide system comprises hydrocone type liquid carbon dioxide liquid storage bottle 1, evaporation coil 2, described hydrocone type liquid carbon dioxide liquid storage bottle 1 has a plurality of and parallel with one another connecting, and described hydrocone type liquid carbon dioxide liquid storage bottle 1 is connected nozzle 3 with evaporation coil 2 successively by pipeline and is connected with the throttling expansion refrigeration system; Described throttling expansion refrigeration system comprises nozzle 3, expansion space 4 and heat exchanger 5, and described nozzle 3 is installed in 4 inside, expansion space, connects with pipeline between expansion space 4 and the heat exchanger 5, and described heat exchanger 5 outlets are connected with evaporative cooling system; Described evaporative cooling system is comprised of indirect evaporative cooling device 6; Described nozzle 3 utilizes the high pressure and the pressure reduction between the atmospheric pressure that produce after the working medium gasification heat absorptions such as liquid carbon dioxide, liquid nitrogen or freon to produce joule-thomson refrigeration effect; Described devaporizer 6 utilizes the gaseous carbon dioxide that relative humidity is lower after throttling expansion to produce heatcooling effect.
Specific works process of the present utility model is as follows: when needs freeze, open wherein one bottle of hydrocone type liquid carbon dioxide liquid storage bottle 1, liquid carbon dioxide enters evaporation coil 2, and the liquid carbon dioxide endothermic gasification produces refrigerating capacity, and expands rapidly.The HCS that the carbon dioxide decalescence produces is through nozzle 3, and the outlet of 4 inner nozzles 3 produces low-temperature airflow in the expansion space.This low-temperature airflow heat exchanger 5 of flowing through, through with the abundant heat exchange of heat exchanger 5, gas flow temperature is increased to room temperature gradually, then enters devaporizer 6 by heat exchanger 5.Carbon dioxide contacts with hydrophily in devaporizer 6, causes the evaporation of hydrophily, thereby produces refrigerating capacity, finishes whole process of refrigerastion.
The quantity of hydrocone type liquid carbon dioxide liquid storage bottle 1 described in the utility model is decided by personnel amount in the survival capsule is different with design length service time.
