Temperature regulating device for mine rescue capsule

Abstract

The invention discloses a temperature regulating device for a mine rescue capsule, comprising a surface cooler 300 arranged in the rescue capsule, wherein a fan 303 is arranged in the surface cooler 300. The temperature regulating device also comprises a CO2 liquid storage bottle 100, a throttling pipeline is arranged between the CO2 liquid storage bottle 100 and the cooling medium inlet of the surface cooler 300 and is provided with a throttle 200, the cooling medium outlet of the surface cooler is connected with a CO2 exit pipe 400 communicated with atmosphere, and the CO2 exit pipe 400 extends out of the rescue capsule. Liquid CO2 is gasified to adsorb heat in the surrounding air, and cooled air circularly flows in the rescue capsule so as to obtain the purpose of regulating temperature. In addition, CO2 is directly discharged out of the rescue capsule from the surface cooler after gasified without being reused, and no compressors are needed so as to greatly save power resource in the rescue capsule, thus the temperature regulating device can be normally used under the extreme working conditions, such as mine disasters. The throttle controls the gasification amount of the liquid CO2, and the control method is simple and convenient.

Description

technical field [0001] The invention relates to a temperature regulating device, in particular to a temperature regulating device for a mine rescue cabin. Background technique [0002] Due to the unpredictability of mining disasters, in recent years, some mining disasters in my country have caused huge losses of life and property to the country and society. Therefore, when mining disasters occur, mine rescue cabins become the first choice for underground miners to escape. [0003] The mine rescue cabin is generally equipped with a temperature regulating device, such as the application number: 200810010796.3 involved in a mine refuge cabin, the cabin is equipped with a cooling device, including refrigerant, cooling water pipes and spray water pipes, usually using low capacitance Electric energy maintains the refrigerant in a solid state, and when a mine accident occurs, it cools down by melting and absorbing heat. This method cannot be controlled when the temperature in the c...

Problems solved by technology

[0004] The refrigerants currently used are generally fluorine-containing. In the 1970s, CFC and HCFC were found to destroy the ozone layer of the atmosphere and have a high greenhouse effect index, so they faced a complete ban.
