Abstract
An overhead fan system of a building comprises a ceiling fan underneath a nearby fire sprinkler head. The ceiling fan has particularly low fan solidity to minimize the fan obstructing the spray of water from the sprinkler head. To further reduce the obstruction, some example fans include fan blades that automatically retract in the event of a fire.
