Tunnel Cooling Air Conditioning Unit (Tunnel Cooling Air Conditioner)

Engineering Tunnel Cooling Air Conditioning Unit

During tunnel excavation, high-temperature surrounding rock may expose workers and equipment to extreme heat, adversely affecting health and work efficiency. Traditional tunnel cooling methods rely on ventilation, pumping fresh air from the tunnel entrance to near the excavation face. However, in long tunnels, air heated by the high-temperature rock over long distances can reach temperatures nearly identical to the tunnel's original temperature by the time it arrives, offering minimal cooling effect. Efficiently and economically reducing high temperatures in deep, long tunnels during construction to improve the working environment is an urgent issue. Therefore, a mobile, custom-designed tunnel cooling air conditioning unit must be installed to locally cool the work area, lowering temperatures to provide a comfortable environment for workers.

Unit Advantages

1.Compressor refrigeration, high cooling capacity, adjustable temperature from 5°C to 30°C ±3°C (adjusted based on actual 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, brand-new products from the factory, using stable performance brands with low failure rates. The company strictly prohibits the use of refurbished refrigeration compressors.

Working Principle

Select a location in the tunnel to place the cooling unit, which draws in tunnel air, cools it as a cold source, and then uses a fan to deliver the cooled air to the mining operation area for effective temperature reduction, achieving the desired ideal temperature in the work zone.

Tunnel Cooling Air Conditioning Unit Features.

1. Scientifically designed, meticulously manufactured, aesthetically pleasing appearance, reliable performance, and quality.

2. Utilizes centrifugal fans for high air volume, long-distance air delivery, and low noise.

3. The unit includes eight protection functions: high-pressure protection, low-pressure protection, phase sequence protection, phase loss protection, overheating protection, overload protection, freeze protection, and air deficiency protection.
