Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention will be further described

[0022] During the normal production of coal mines, such as figure 1 and Figure 6 As shown, the coal mine underground movable rescue cabin is placed on the underground working face, and the cabin is equipped with food and drinking water necessary to maintain the survival of the rated number of people in the cabin within a specified time. At this time, high-pressure compressed air is sent into the coal mine underground movable rescue cabin. In the rescue cabin, the valve one (12) is closed, the valve two (11) is opened, the high-pressure compressed air is sent into the refrigeration system (1) through the pipeline, and the cold air is introduced into the phase change material cold storage system (9) through the pipeline (15-2), The phase change material is frozen to store cold energy. After passing through the phase change material cold storage system (9), the airflow heat...

Abstract

The invention discloses a living environment control system in a coal mine underground movable lifesaving cabin, comprising a lift support system and an air-conditioning system, wherein the life support system is composed of an air circulating system, an air purification system and an oxygen regenerator; the air-conditioning system has a refrigerating system, a phase-change material cold accumulation system and a heat exchange system; and the invention has simple structure and convenient use, miners can enter into the cabin to start the living environment control system of the movable lifesaving cabin according to the requirements of operating instructions when a mining accident happens, and the lift support system adopts a proven aerospace and submarine oxygen regeneration principle to work stably and reliably. High pressure oxygen cylinder with explosion risk can be saved in the cabin, thus reducing the shockproof requirement on the cabin and greatly reducing the volume of a CO2 absorption device; and the refrigerating system in the air-conditioning system is characterized by adopting no transmission parts (vortex tube refrigeration) or less transmission parts (turbo-expander refrigerator) and having no power demand, thus avoiding depending on power in the traditional refrigeration mode.

Description

technical field [0001] The invention relates to a living environment control system in an airtight cabin, in particular to a living environment control system in a movable rescue cabin under a coal mine. Background technique [0002] In recent years, mining accidents have occurred frequently, and after mining accidents, miners died frequently due to the lack of necessary shelters. At present, there are several types of movable rescue chambers sold by foreign companies on the market. These rescue chambers include oxygen supply systems and air-conditioning systems. That is, high-pressure oxygen cylinders are used to supply oxygen and vapor compression refrigeration systems are used to complete refrigeration. However, since the oxygen supply is supplied by high-pressure oxygen cylinders, the CO exhaled by the occupants in the cabin 2 Need to use special equipment to absorb. At the same time, due to the use of the vapor compression refrigeration system to complete the refriger...
