Abstract: The high temperature and heat damage in the construction stage of tunnel engineering will not only reduce the work efficiency of workers, but also may cause safety hazards and threaten the lives of workers. Based on the analysis of the causes of high temperature in tunnel construction, the article designs and develops a cooling system with refrigeration units as the core, and uses it to achieve mechanical cooling. It is found that this system can reduce the air temperature by about 15 ℃ , ensuring that the ambient temperature and humidity of the working surface are below 25 ℃ and 75%, respectively.
