More mist sprayers please

THE World Expo's popular mist sprayers are going to be seen in more areas across the city, starting with the Oriental Pearl TV Tower.

Tower management is installing 32 spray systems by the end of this month. The tower's waiting area is expected to be about 5 degrees Celsius cooler than the outdoor temperature when the sprayers are in use.

Sprayers will also be set up in communities, schools and squares if further experiments succeed, said Huang Chen, a professor responsible for the design.

The mist sprayers have proven effective at the waiting areas of more than 40 popular Expo pavilions and have been welcomed by visitors.

The Expo organizer installed electric fans to work in tandem with the sprayers to help cool down visitors waiting for several hours to enter popular pavilions.
