Abstract: The centrifugal spraying device comprises a fan, a rotating spray unit and a cyclone air flow. It consists essentially of a hollow cylinder, the lower part of which is drilled with spray apertures and whose upper part is provided with flats with recesses against which are fixed blades comprising a cylindrical root extended by a threaded rod provided with a nut. The hollow cylinder is fed by injectors drilled with nozzles and is connected to the output shaft of the drive motor by means of a hollow shaft. The inner wall of the hollow cylinder is separated vertically by a collar located just above the first row of spray apertures. Main application: treatment of crops.

Abstract: The invention concerns an air conditioning installation with centrifugal sprayers (1). Said installation is essentially comprised of centrifugal sprayers (1) each provided with a deflector (2) and connected to a loop circuit (3) incorporating a buffer reservoir (4) which is supplied with liquid, a centrifugal purifier (5), a filter (6), a pump (7), individual flow regulating devices (8) and a collective flow regulating electro-valve (9), controlled by a regulation device (10) which is servo-controlled by a temperature sensor (11) and by a hygrometry sensor (12). The driving motors (13) for the sprayers (1) are power supplied through an adjustable frequency inverter (14).
