Climate island

An automatic ceiling diffuser system of a room, the system being suitable for heating, cooling and ventilating the room by radiation and thermal convection, the system comprising at least one modular island intended to be attached to the ceiling of the room, the modular island comprising:

• a peripheral frame provided with at least one line attachment of a diffuser element such as a taut fabric situated in its lower part opposite the ceiling;
• on one or more of its faces, the peripheral frame comprises a slit for blowing air toward the room;
• a diffusion element such as a taut fabric, attached to the attachment line of the peripheral frame, visible from the room and forming the horizontal bottom face of the modular island;
• a top cover forming the top face of the modular island facing the ceiling;
• an air blowing connection outlet fixed to the suction box of the modular island and allowing the injection of treated air into the internal volume of the modular island;
• a channel of articulated baffles formed by an upper articulated baffle and a lower articulated baffle, fixed to the peripheral frame at the air blowing slit and making it possible to orient the blown air at an angle defined with respect to the ceiling varying from 0°, and namely parallel to the ceiling when cold air is blown into the island, to a maximum of 70° when hot air is blown into the modular island;
• a thermostatic actuation means making it possible to actuate the channel of articulated baffles via a baffle actuation means such as an actuation rod and conferring on the channel a blowing angle dependent on the temperature of the treated air injected into the modular island the thermostatic actuation means comprising a piston, the outlet stroke of which depends on the temperature of air in which the thermostatic actuation means is immersed;
• a return spring making it possible to exert a force opposite the stroke of the piston of the thermostatic actuation means and thus make it revert to its minimal stroke when cold air is blown into the modular island, and in which the channel of articulated baffles comprises an articulated means for maintaining parallelism positioned in the channel and linking the upper and lower articulated baffles to the articulation points B and C respectively, the upper and lower articulated baffles fixed to the peripheral frame at articulation points A and D describing, with the articulation points B and C of the articulated means for maintaining parallelism, a parallelogram A-B-C-D imposing a parallelism on its opposite faces, wherein the modular island further comprises an air suction connection outlet fixed to the top cover of the modular island and communicating with a suction box provided with a filter sucking the ambient air from the room from the top cover of the modular island.

A modular island intended for heating, cooling and ventilating a room by radiation and thermal convection, the modular island being able to be suspended from the ceiling of a room, the modular island comprising:
