Summary of the invention
For solving the problems referred to above that prior art exists, the present invention will design a kind of air cooling system that is used for mine rescue capsule of non-electricity.
To achieve these goals, technical scheme of the present invention is as follows: a kind of air cooling system that is used for mine rescue capsule comprises liquid carbon dioxide refrigeration system and spray type refrigerating system, and described liquid carbon dioxide refrigeration system and spray type refrigerating system connect into the joint refrigeration system by pipeline; Described liquid carbon dioxide system comprises hydrocone type liquid carbon dioxide liquid storage bottle, bus-bar, the high pressure dryer, heating power expansion valve, adiabatic pipeline, evaporation coil, pressure-control valve, safety valve, described hydrocone type liquid carbon dioxide liquid storage bottle has a plurality of and connects by bus-bar, described bus-bar by pipeline successively with the high pressure dryer, heating power expansion valve, adiabatic pipeline, evaporation coil is connected with pressure-control valve, be connected with safety valve by tee pipe coupling between evaporation coil and pressure-control valve, the temperature-sensitive bag of described heating power expansion valve is installed in the exit of evaporation coil; Described spray type refrigerating system comprises fine film evaporimeter, nozzle and ejector, and described ejector is connected with nozzle with the fine film evaporimeter by pipeline respectively, and described ejector is installed on the lifesaving bulkhead.
The pressure-control valve of liquid carbon dioxide refrigeration system of the present invention is connected by pipeline with the nozzle of spray type refrigerating system.
Hydrocone type liquid carbon dioxide liquid storage bottle of the present invention is exported to the pipeline outsourcing heat insulation layer between the thermal expansion valve outlet port.
Spray type refrigerating of the present invention system is a kind of open refrigeration system that cold-producing medium is directly sprayed into atmosphere, frozen-free device.
Liquid carbon dioxide cold-producing medium in the spray type refrigerating of the present invention system also can be that other can discharge latent heat at ambient temperature and produce gases at high pressure, then can produce the cold-producing medium of high velocity air by nozzle.
Two kinds of different working medium of spray type refrigerating system's employing of the present invention are respectively as working fluid and driving fluid.
Compared with prior art, the present invention has following beneficial effect:
1,, works alone in that survival capsule is indoor, for necessary cold is provided in the survival capsule because the air cooling system that is used for mine rescue capsule among the present invention externally under the situation of dump and inner no storage battery.
2. the air cooling system that is used for mine rescue capsule among the present invention has high coefficient of refrigerating performance.
Therefore 3, because the present invention is not provided with any parts in the survival capsule outside, need not do any explosion-proof processing, it can and be existed in the hazardous area of flammable gas explosion in the colliery use.
4, since the air cooling system that is used for mine rescue capsule among the present invention be one by liquid carbon dioxide refrigeration system and the system combined refrigeration system of forming of spray type refrigerating, make full use of the latent heat of liquid carbon dioxide and the pressure energy after its gasification, improved the refrigerating capacity of unit mass liquid carbon dioxide.Under the situation that satisfies the cabin environment temperature, reduce the memory space of liquid carbon dioxide, save the space in the cabin.
