Problems solved by technology

[0003] Among them, electric air-conditioning cooling and electric ice-storage air-conditioning cooling both use electric power to drive vapor compression refrigeration, which has the advantages of large cooling power and high efficiency, but the disadvantage is that in the special environment of the underground, especially the refuge chamber, the use of electricity will bring storage capacity on the one hand. On the one hand, there are hidden dangers in explosion-proof safety

Abstract

The ore pneumatic refrigeration device and method and method use steam compression refrigeration. The compressor gas motor drives the refrigeration compressor. The refrigerant is compressed to a high -temperature and high -pressure state after the refrigerant is used through the refrigerant.The high -temperature, high -pressure gaseous refrigerant of the condenser is condensed into liquid, and the high -pressure liquid refrigerant is entered into the inflating valve through storage tanks and dry filters through storage tanks and dry filters.Take away the heat of the cooling agent of the same heat exchanger, the refrigerant after the heat absorbers returns the refrigeration compressor through the gas liquid separator to complete a working cycle.

Description

technical field [0001] The invention relates to a pneumatic refrigeration device and method for an ice-storage air-conditioning system for a refuge chamber, which can be used for ice-storage refrigeration in underground refuge chambers of mines, and can also be used for local cooling of mines, and belongs to the field of mining safety and heating, ventilation and refrigeration. Background technique [0002] Currently, there are five cooling methods for coal mine refuge chambers: electric air-conditioning, electric ice-storage air-conditioning, liquid carbon dioxide, phase-change materials, and ventilation. [0003] Among them, electric air-conditioning cooling and electric ice-storage air-conditioning cooling both use electric power to drive vapor compression refrigeration, which has the advantages of large cooling power and high efficiency, but the disadvantage is that in the special environment of the underground, especially the refuge chamber, the use of electricity will b...
