A device for regulating the temperature of premises by a secondary air flow blown therein, comprises an upstream duct communicating with elements for supplying pressurized air, ending in a converging element emerging into a downstream duct communicating with the premises. The device is characterized in that a substantially rotating solid, capable of being positioned along the convergent element longitudinal axis, is arranged at least partially upstream of the outlet thereof, so as to define between the substantially rotating solid outer surface and the convergent element inner wall with a ring-shaped channel the size of which depends on the position of the solid relative to the wall.
