Document Type and Number:
WIPO Patent Application WO2006060417
Kind Code:
A3
Abstract:
A spot ventilator (12,14,16,18) and method for spot ventilating a localized environment of a building (10) is provided. The spot ventilator (12,14,16,18) includes a passage (36) and at least one corona discharge apparatus (50). The passage (36) extending between an inlet (38) positioned in the localized environment and an outlet (56). The at least one corona discharge apparatus (50) positioned in relation to the passage (36) such that a fluid from the localized environment is drawn into the passage (36) through the inlet (38) and is expelled through the outlet (56). The method of ventilating a localized environment of a building (10) includes the steps of sensing a first change in the localized environment, energizng a corona discharge apparatus (50) to produce an electric wind, drawing air from the localized environment into a passage (36) via the electric wind and expelling the air from the passage (36) through the outlet (56).
