Improving Efficiency of Tunnel Fan Control in Shallow Subway
- 4 Downloads
The data of the full-scale experiment on adjustment of VOMD-24 fan rotor speed with a view to controlling the fan efficiency under impact of the piston effect are presented. The reduction in actual air flow rate at the passenger platform of subway due to decreased fan efficiency is estimated at different intensity of traffic along the subway line. The algorithm of the tunnel fan rpm adjustment per day in conformity with the train traffic density and the architecture of automated control of the tunnel fan efficiency by frequency transducer are proposed.
