Mine emergency hedge facility refrigeration assembly

Abstract

The invention provides a mine emergency hedge facility refrigeration assembly. The mine emergency hedge facility refrigeration assembly at least comprises a shell, a refrigeration device and an air supplying device, wherein the shell is used for storing ice blocks and containing and protecting an ice storage cabinet, the refrigeration device is arranged on the outer side of the shell and used for providing cold air to enable the ice blocks to keep the temperature, the air supplying device is arranged on the outer side of the shell and used for supplying hot air into the shell, an interlayer cavity is formed between the ice storage cabinet and the shell, and the refrigeration device and the air supplying device are communicated with the interlayer cavity. The mine emergency hedge facility refrigeration assembly can still normally operate even when electric power supply is completely damaged and can carry out refrigeration under the normal state without electric power, and accordingly a refuge chamber or an escape capsule or other facilities are located at the preference temperature. The mine emergency hedge facility refrigeration assembly is simple in structure, convenient to mount and maintain, long in service life, low in maintaining cost, short in starting time, capable of effectively preventing pollutant or explosive from being produced and high in safety performance.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a refrigeration assembly of a mine emergency avoidance facility. Background technique [0002] In the process of coal mine production, accidents such as gas explosions and landslides will inevitably occur. When these accidents occur, once the people in distress underground cannot escape from the affected area, they can choose to enter the refuge chamber or rescue cabin and other hazard-avoiding facilities to wait for rescue. , because the temperature in the underground is higher and when the mine disaster accident takes place, the temperature will be higher, therefore, there must be a cooling device in the refuge chamber or the rescue cabin. [0003] At present, there are mainly the following methods for cooling refuge chambers or rescue cabins: carbon dioxide phase-change refrigeration, air-conditioning ice storage, etc. Among the above two methods, carbon dioxide phase-change refrigera...

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly the following methods for cooling refuge chambers or rescue cabins: carbon dioxide phase-change refrigeration, air-conditioning ice storage, etc. Among the above two methods, carbon dioxide phase-change refrigeration equipment has complex structure, high installation requirements and complicated operation, and there are The risk of pollutant leakage or high-pressure explosion; the failure rate of air-conditioning ice-making and cooling devices is high, and the daily maintenance costs are high
