Problems solved by technology

The operating pressure of the system is high; the required volume of liquefied gas is large, and the storage cylinder takes up a large space; the carbon dioxide contains moisture, which is easy to cause ice blockage in the pipeline; as the flow rate of liquid carbon dioxide decreases, the cooling capacity released by it is not enough to balance The heat load in the cabin and the temperature and humidity in the cabin will gradually rise, so considering the actual cooling efficiency, only 70% to 75% of the carbon dioxide in the cylinder in the traditional refrigeration system is used, which undoubtedly causes energy and space constraints. waste

Abstract

The invention discloses a mining escape capsule refrigerating system and method, and belongs to the field of confined space safety rescue and environment control. The system comprises a carbon dioxide steel bottle, a pipeline, a primary bypass valve, a primary pressure reduction and throttling valve, a primary temperature meter, a primary capillary evaporator, a secondary communicated valve, a secondary pressure reduction and throttling valve, a secondary temperature meter, a secondary capillary evaporator, a gas exhaust regulating valve and a pneumatic fan. According to the invention, the primary capillary evaporator and the secondary capillary evaporator are adopted to be connected in series and in parallel to arrange and exchange elements, the refrigeration capacity utilization ratio of a refrigerant can be improved effectively, and the refrigeration capacity loss is reduced; and additionally, through the arrangement of the primary temperature meter and the secondary temperature meter, the controllability of system running and operation is improved; and the mining escape capsule refrigerating system provided by the invention has the advantages that performance is safe and stable, regulation is flexible and convenient, is energy-saving, environment-friendly and economic, and the like.

Description

technical field [0001] The invention relates to a refrigeration system and method for a mine rescue cabin, belonging to the field of safe lifesaving and environment control in confined spaces. Background technique [0002] In view of the serious situation of frequent mine safety production accidents in China, relevant regulatory authorities require underground mines to improve production safety facilities and complete the installation of six major systems including 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 cabin is...
