Abstract:
In view of the condition that the tailrace tunnel ventilating application is limited by the length of tunnel in hydropower engineering,an air-parameter control technology with a finite tailrace tunnel length is presented.The technology utilizes the low temperature water to handle the tunnel outlet air by spraying.The performances of the air control technology in an engineering application are analyzed,and the results indicate that the combined technology can break through the limitation of the tunnel length effectively and extend the application of the tailrace tunnel ventilation,and achieve the non-chiller operation of ventilating and air conditioning system in a hydropower station with tailrace tunnel.
