The present invention will be further described with reference to the accompanying drawings and the following detailed description.
The internal structure of the mine air conditioner is shown in fig. 1, and the compressed air inlet 12 of the mine air conditioner is communicated with the expansion inlet 211 of the expansion end 21 of the expansion machine 1 positioned in the mine air conditioner. In order to improve the controllability of the cooling, a control valve 11 is provided between the compressed air inlet 12 and the expansion inlet 211 to control the flow rate of the compressed air inside. The expansion outlet 212 of the expander 2 communicates with the refrigerant outlet 13. At this time, the blower air inlet 221 of the blower end 22 of the expander 2 is communicated with the circulating air inlet 14 of the mine air conditioner 1, and the blower air outlet 222 is communicated with the air outlet 15 of the mine air conditioner 1.
In use, the compressed air inlet 12 is connected to the compressor via the compressed air inlet conduit 3. In order to ensure the air inlet quality, an air purification device is arranged between the compressed air inlet 12 and the compressor, so that the pollution of the refrigeration air to the internal environment of the mine is avoided in the refrigeration process, the internal environment quality of the mine is ensured, meanwhile, the corrosion damage of the compressed air to the internal structure of the mine air conditioner is also reduced, the service life of the structure is ensured, and the refrigeration effect is guaranteed. The refrigeration outlet 13 of the mine air conditioner 1 is connected with one end of the refrigeration pipeline 4, and the other end of the refrigeration pipeline 14 faces towards a refrigeration target area, so that the internal local cooling of the mine is realized, and the temperature requirement of the internal environment of the mine is ensured. In addition, the staff can move the tip position of refrigeration pipeline 14 according to actual demand, has improved the flexibility of control by temperature change operation, has reduced the resource loss. The circulating gas inlet 14 of the mine air conditioner 1 is also connected with the circulating pipeline 5, one end of the circulating pipeline 5 is connected with the circulating gas inlet 14, and the other end of the circulating pipeline 5 can be selected according to the actual situation, so that the air in the corresponding area is sucked into the mine air conditioner, and the air circulation of the corresponding area is promoted.
