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, which draws fresh air from the tunnel entrance and delivers it to the excavation face. However, in long tunnels, the air heats up significantly due to radiation from the hot surrounding rock over long distances. By the time the air reaches the working area, its temperature is nearly the same as the original tunnel temperature, providing 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 movable, custom-designed tunnel cooling air conditioning unit must be installed to locally cool the working area, ensuring a comfortable temperature for construction personnel.

Unit Advantages

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

3. Features rapid cooling, high air volume, ventilation, dehumidification, dust prevention, and heatstroke prevention. Enhances mining work efficiency, saves electricity, reduces costs, enables quick installation, and facilitates maintenance.

4. Integrated unit design for easy mobility.

5. All components are original, brand-new products from the manufacturer, utilizing stable and reliable brands with low failure rates. The company strictly prohibits the use of refurbished compressors.

Working Principle

The tunnel cooling air conditioning unit is placed at a selected location within the tunnel. It draws in tunnel air, cools it through refrigeration, and uses it as a cold source. A fan then delivers 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 and meticulously manufactured, with an attractive appearance, excellent performance, and reliable quality.

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

3. The unit is equipped with eight protection functions: high-pressure protection, low-pressure protection, phase sequence protection, phase loss protection, overheating protection, overload protection, freeze protection, and air shortage protection.

4. The unit control employs a human-machine interface microcomputer system, which can include a touch screen and features an R485 communication port for remote control.

6. Uses national standard refrigerants. The company's self-developed mixed refrigerants can be selected based on different usage environments.
