Cooling and dehumidifying device of refuge chamber for mines

The utility model provides a cooling and dehumidifying device of a refuge chamber for mines, which resolves the problem that using air conditioners directly in the refuge chamber can lead to new irresolvable problems. The cooling and dehumidifying device of the refuge chamber for mines is characterized in that a liquid state carbon dioxide steel cylinder, a high pressure gauge, a master valve, a throttling valve, a thermostatic expansion valve, an evaporator, a low pressure gauge, a reversing valve and a pneumatic fan are connected in sequence through pipelines. The liquid state carbon dioxide steel cylinder is arranged in a transition region, and the other parts are arranged in a living area. After a mining disaster happens, the cooling and dehumidifying device of the refuge chamber for mines can work independently, thereby providing the refuge chamber with a reliable cooling and dehumidifying device and further facilitating the guarantee of life safety of miners and the prolonging of rescue time.
