Description

technical field

[0001] The invention relates to a refrigeration device and method for a mine rescue cabin, belonging to the field of safe lifesaving and environment control in confined spaces. Background technique

[0002] In response to the serious situation of frequent mine safety production accidents in China, the relevant regulatory authorities require underground mines to improve production safety facilities and complete the installation of six major devices such as emergency avoidance before June 2013, so as to deal with various sudden dangers and reduce Accidents and casualties. As a new type of emergency avoidance equipment, the mine rescue cabin can provide a safe refuge for those in distress underground who cannot evacuate in time. Combined with active self-rescue, it plays a vital role in making the rescue work scientific and effective.

[0003] The domestic mine safety situation is severe, and the development of rescue cabins is urgent. The space inside the ca...
