摘要
A method for calculating the amount of energy conservation of open controllable circulating ventilation for an extra-long highway tunnel. The method comprises the following steps: firstly, determining a calculation formula for the total power consumed by an open controllable circulating ventilation system; then, determining a calculation formula for the total power consumed by a conventional air supply and exhaust vertical shaft ventilation method; and through comparison with the conventional air supply and exhaust vertical shaft ventilation method, determining a calculation formula for the amount of energy conservation of the open controllable circulating ventilation system. Where the volume of exhaust airflow of the conventional air supply and exhaust vertical shaft ventilation method and the volume of parallel airflow in a short tunnel channel (14) are determined, and given the circulation ratio and purification efficiency of the open circulating ventilation system and the friction air resistance coefficient of a main branch thereof, a ventilation power consumption value saved by means of the implementation of the open controllable circulating ventilation system can be calculated, thereby quickly completing pre-evaluation of the implementation of the open circulating ventilation system.
