<p>PROBLEM TO BE SOLVED: To achieve mist spray that establishes compatibility between suppression of an increase in temperature inside a tunnel and securement of a visual environment for a user inside the tunnel.SOLUTION: A spray system for decreasing a temperature inside a tunnel suppresses an increase in the temperature inside the tunnel after securing a visual environment by spraying the water as a mist from a spray nozzle (10) inside the tunnel that is a semiclosed space. A fitting position of the spray nozzle arranged on the leeward side inside the tunnel is set higher than a fitting position of the spray nozzle arranged on the windward side inside the tunnel.</p> |
