Abstract
Description
Technical Field
[0001] The utility model relates to the field of mine tunnel refrigeration, in particular to a mine refrigeration unit. Background Art
[0002] The construction environment of underground projects such as mining and tunneling is often harsh. How to improve the construction environment of underground projects and provide construction workers with a guaranteed construction environment is of great significance to construction units. Take coal mining as an example. The underground tunnels of coal mines are narrow and have very limited ventilation conditions. In addition, the continuous operation of construction equipment often leads to high temperatures in the tunnels, which often makes construction workers feel hot and stuffy.
[0003] In order to improve the ambient temperature of underground mine tunnels, refrigeration units are used in the prior art to cool down the tunnels. Since air cooling and water cooling have their own advantages and disadvantages, air cooling and water cooling should be set for different situations.
