AI Technical Summary
⚠Technical Problem
Conventional water spray systems in tunnels require large amounts of water discharge, necessitating large pumps and large-diameter piping, leading to increased costs.
⚗Method used
The system divides water spray heads into groups and controls water discharge alternately or sequentially by group, using sensors to identify the fire source and control water discharge only to the fire location, reducing the amount of water used per unit time.
🎯Benefits of technology
This approach reduces the size of pumps and piping, lowering equipment costs while maintaining effective fire suppression and structural protection.

Abstract
The objective is to provide a water spray system and a water spray system that can reduce the amount of water used during a fire and reduce costs by miniaturizing pumps and piping. [Solution] The present invention relates to a water spray equipment water discharge control method, which is a water spray equipment 1 equipped with a plurality of water spray heads 5 provided at predetermined intervals in the longitudinal direction of a tunnel 3, characterized in that the plurality of water spray heads 5 are grouped into a plurality of groups, and the water discharge is controlled so that the groups to discharge water are switched alternately or sequentially to discharge water in group units.
