Abstract
Shenzhen metro has been applied the VFD control technique and close loop negative control logic to adjust and control the temperature and humidity of public area and conserve the energy on HVAC system of children palace station and Fumin station of NO.4 line of the first phase project of the metro, which can save over 70% electrical energy than before. And the equipment operated very well in more than one year, and the environment quality is very stable, has achieved obvious efficient.
