Tunnel Cooling Low-Temperature Air Conditioning Unit (Tunnel Cooling Air Conditioner)

Engineering Tunnel Cooling Low-Temperature Air Conditioning Unit

During tunnel excavation, high-temperature surrounding rock can create a hot working environment for both personnel and equipment, which is detrimental to health and work efficiency. Traditional tunnel cooling methods rely on ventilation, where fresh air from outside the tunnel entrance is directly delivered to the tunnel face to reduce temperatures. However, in long tunnels, the air is heated by the high-temperature radiation from the surrounding rock over long distances, causing its temperature to rise to nearly the same as the original tunnel temperature before reaching the working face. This results in minimal cooling effect. Efficiently and economically reducing high temperatures in deep and long tunnels during construction to improve the working environment is an urgent issue. Therefore, a movable, customized low-temperature air conditioning unit for tunnel cooling must be installed in the tunnel to provide localized cooling in the working area, lowering the temperature and creating a cooler environment for construction personnel.

Unit Advantages

1.Compressor refrigeration, high cooling capacity, adjustable temperature range 5°C to 30°C ±3°C (adjusted according to actual working conditions),

3. Rapid cooling, high air volume, ventilation, dehumidification, dust prevention, and heatstroke prevention advantages. Improves mining efficiency, saves electricity, reduces costs, quick installation, and easy maintenance.

4. Integrated unit design for easy mobility.

5. All components are original factory-new products, using stable and reliable brands with low failure rates. The company strictly prohibits the use of second-hand or refurbished refrigeration compressors.

Working Principle

Select a location in the tunnel to place the low-temperature air conditioning unit for tunnel cooling. Extract air from the tunnel, cool it, and use it as a cold source. Then, through the action of a fan, deliver the cold air to the mining operation area for effective cooling, reducing the temperature in the working area to the desired ideal level.

Tunnel Cooling Low-Temperature Air Conditioning Unit Features.
