When tunnels are being excavated for railways, highways, and subways in southern China, temperatures inside tunnel portals can sometimes reach 42°C. In response to market demand, our company has developed a tunnel air-conditioning system designed for use on tunnel boring machines, which effectively mitigates high ambient temperatures within the tunnel. This system has already been successfully deployed in Guangdong’s subway projects, where it helps maintain tunnel temperatures below 30°C even during the hottest summer conditions.
