Abstract

The invention discloses a pneumatic ice storage air conditioning device for downhole rescue. The pneumatic ice storage air conditioning device comprises a mechanical refrigeration module consisting of a compressor, a safety valve, an oil separator, a condenser, a liquid storage device, a drying filter, a liquid spraying valve, a thermal bypass valve, a gas-liquid separator, a stop valve and the like, an ice storage box module consisting of liquid sight glass, a thermal expansion valve, an ice storage box, a stop valve and the like, a gas path module consisting of a compressed air source, an air filter, a pressure release valve, an atomized lubricator, a pneumatic motor, a flow adjustment valve, a pneumatic condensation fan, a muffler and the like, and a cold release module of a compressed air steel bottle, an adjustment hand valve, a pressure adjuster, a pneumatic fan, a muffler and the like. The pneumatic ice storage air conditioning device for downhole rescue is high in refrigeration efficiency; downhole compressed air is used as an air source, and no power supply is needed in a working process; a refrigeration system adopts a supercooling design; the system can realize continuous running, and a press does not need to be automatically controlled to be switched on and switched off; the compressor is connected with the pneumatic motor through a belt in a transmission manner; the pneumatic ice storage air conditioning device is high in assembling efficiency, and the transmission ratio is controllable.

Description

technical field [0001] The invention relates to an air conditioner for underground lifesaving, in particular to a pneumatic ice storage air conditioner for underground lifesaving. Background technique [0002] The air conditioner for underground lifesaving is generally used in underground rescue cabins and refuge chambers. At present, this type of product mainly adopts two methods of ice storage refrigeration and liquid carbon dioxide refrigeration. With the clarification of rescue chamber and refuge chamber technology and specifications, coal mines now require the refrigeration of rescue chambers and refuge chambers to minimize the occurrence of secondary injuries. Liquid carbon dioxide refrigeration requires a large amount of gas storage and a large number of cylinders due to the limited cold capacity that can be stored in a single bottle of carbon dioxide. Calculated on the basis of a single cylinder of 70L, the weight of liquid carbon dioxide that can be accommodated in...
