[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] During the tunnel excavation process, since the mining personnel are only at the excavation head, the cooling demand is mainly to cool the local temperature 30m away from the excavation head. In view of the fact that the tunnel is excavated forward all the time, in order to meet the comfort requirements of the mining personnel, the equipment needs to be moved with the advancement of the excavation face, which is undoubtedly a challenge to the mobility and installation cycle of the equipment itself and the progress of the project; first, the harsh working environment underground, including high temperature, high humidity, low oxygen and other conditions, all of which greatly affect the safety and operation of the construction personnel; second, the narrow working space underground, which not only limits the use of large equipment, but also increases the difficulty of construction operations; third, complex equipment and expensive costs, underground equipment and technology are very expensive, and the maintenance and repair costs are also high, which greatly increases the economic pressure of the project. The original underground local refrigeration system includes refrigeration host, air cooler, cooling device and water pump pipeline. According to relevant project data statistics, the installation period of a system is close to 1.5 to 3 months, and the engineering materials and installation costs account for about 30% to 40% of the total project cost. In addition, the original underground local refrigeration system adopts the cooling method of fresh air + direct drainage, and the condensation heat generated by the refrigeration unit when working requires a large amount of underground water resources. Therefore, the present invention adopts an integrated and separate treatment and utilization method of fresh air and exhaust air to solve the above problems.

[0026] According to an embodiment of the present invention, a refrigeration device is provided. Figures 1 to 5 , The refrigeration device is arranged in a tunnel, and the tunnel includes an excavation location 6 and an air duct 9. The refrigeration device is used to cool the excavation location 6 in the tunnel, and includes: A ventilation component 1, wherein the ventilation component 1 is arranged in a tunnel; a refrigerator 2, wherein the refrigerator 2 is connected to the ventilation component 1, wherein the refrigerator 2 is used to reduce the temperature of the fresh air in the ventilation component 1 to form cold air, and wherein the cold air is used to cool the excavation location 6; after the cold air cools the excavation location 6, the cold air is converted into exhaust air, and when the exhaust air returns along the tunnel, the exhaust air passes through the refrigerator 2 and takes away the heat generated by the refrigerator 2; the refrigerator 2 is movably arranged along the extension direction of the tunnel; an exhaust component 14, wherein the exhaust component 14 is arranged in the tunnel, and wherein the exhaust component 14 is used to guide the direction of the exhaust air.

[0027] By adopting the above technical scheme, fresh air is sent into the refrigerator 2 through the ventilation component 1, and the temperature of the fresh air is reduced by the refrigerator 2 to form cold air. The excavation place 6 is cooled by the cold air. After the cooling treatment, the cold air is converted into exhaust air. When the exhaust air returns along the tunnel, the exhaust air passes through the refrigerator 2 and takes away the heat generated by the refrigerator 2, thereby eliminating most of the pipeline valves, water pumps and other engineering materials in the system, greatly shortening the installation of the refrigeration system and the subsequent relocation cycle, reducing the difficulty of operation and construction, and having full and comprehensive guarantees in terms of project investment, construction, operation and maintenance, and not requiring a large amount of water resources, thereby solving the problems of large initial investment, complex system, large consumption of mine fresh air and water resources in the use of the refrigeration system in the tunnel.
