Ice storage air-conditioning system for refuge chamber

Abstract

The invention discloses an ice storage air-conditioning system for a refuge chamber, that is, a double-power ice storage air-conditioning system which makes and stores ice by taking mining pressure air as power in a normal standby state and which is used for storing cold and is driven by the pressure air or by manual power in emergency circumstances that disaster occurs in a mining shaft. The ice storage air-conditioning system comprises a double-power air-conditioning device, a refrigeration device, a temperature control device and an ice storage device, wherein the refrigeration device is driven by the mining shaft pressure air; the refrigeration device is used for reducing the temperature of the ice storage device to store the ice in a phase change manner; the temperature of the ice storage device is controlled through the temperature control device; the double-power air-conditioning device can be driven by the mining shaft pressure air or by manual stamping power, that is, is driven by the mining shaft pressure air in the normal standby state and is driven by the pressure air or the manual power in emergency circumstances that disaster happens to the mining shaft, thereby achieving the air-conditioning function.

Description

technical field [0001] The invention relates to an ice-storage air-conditioning system for refuge chambers, which can be used for cooling, dehumidification and air purification in underground refuge chambers of mines, and can also be used for cooling in mine bureaus, and belongs to the field of mining safety and heating, ventilation and refrigeration. Background technique [0002] Currently, there are five cooling methods for coal mine refuge chambers: electric air-conditioning, electric ice-storage air-conditioning, liquid carbon dioxide, phase-change materials, and ventilation. Among them, the cooling of the electric air conditioner is mainly used for cooling the refuge chamber of the coal mine after the explosion-proof transformation of the compression refrigeration air conditioner. When in use, it is powered by an explosion-proof large-capacity and high-power battery, or it is powered by a drill hole on the ground when there is a drill hole directly leading to the chambe...

AI Technical Summary

Problems solved by technology

Its advantage is that carbon dioxide absorbs a lot of heat when it changes from a liquid state to a gaseous state, and the flow of vaporized carbon dioxide gas can provide power to the fan to realize forced convection heat transfer and refrigeration without electricity; the disadvantage is that the amount of carbon dioxide is large and the volume is large, and the carbon dioxide cylinder and There may be leakage at the pipe connection, it is difficult to ensure the amount of inflation before use, a large amount of carbon dioxide is discharged into the roadway during use, it is difficult to quickly restore the ventilation of the roadway, and the progress of disaster relief is affected. It is difficult to restore the cooling system after use, and carbon dioxide is a greenhouse gas.

Its advantage is that there is no need to consider the power source in the chamber, and there is no cooling device. It can supply fresh air to the chamber and bring out the polluted gas in the chamber. Drilling temperature is greatly affected, and the required air volume is large

[0003] In the ventilation and cooling technology, in order to ensure that the chamber cooling system can still work normally when the compressed air pipeline or the ground borehole is damaged by disasters, the usual practice is to design the groundwater access system to cool down, but this solution needs to be connected Complicated water pipes greatly increase operating costs

At present, there is no cooling solution with simple structure and convenient maintenance without connecting to the groundwater system
