Abstract

The invention discloses a cold conveying system of a mine air-conditioning and a working method of the cold conveying system. The cold conveying system of the mine air-conditioning comprises a refrigerating device, a heat exchanger and an air cooler, wherein the refrigerating device is distributed on the ground, the heat exchanger is distributed underground, and the air cooler is distributed at an underground cooling working point; a sealed circulation system is formed by an evaporator at the refrigerating device distributed on the ground and the heat exchanger distributed underground through a pipeline and is filled with refrigerating agents, and thus the circulation system is called as a refrigerating agent circulation system; and a sealed circulation system is formed by the heat exchanger distributed underground and the air cooler distributed underground through the pipeline and a circulation pump and is filled with cooling water, and thus the circulation system is called as a cooling water circulation system. According to the cold conveying system of the mine air-conditioning, disclosed by the invention, the cooling for the underground working point is realized, and the purposes that the cold conveying system of the mine air-conditioning has a low energy consumption, a good cooling effect and a low cost are realized.

Description

technical field [0001] The invention relates to a mine air-conditioning cold delivery system, in particular to a system and a method for transporting cooling capacity by refrigerant circulation in a mine vertical shaft. Background technique [0002] At present, the mining depth of coal mines in my country is mostly above 800m and is gradually increasing. The degree of comprehensive mechanization continues to increase, and the heat emitted from geothermal heat and underground equipment to the underground air has increased significantly. The heat release of surrounding rocks not only increases the temperature in the mine, but also increases the humidity; the high temperature and high humidity environment in the mine seriously affects the health and production efficiency of underground workers, and has caused disasters - heat damage. Mine heat damage will eventually become the decisive factor restricting the depth of mineral mining. Therefore, mine air conditioners must be used ...
