    (54) A suspended ceiling structure and a method for flowing air in connection with the suspended ceiling structure


    (57) The invention relates to a suspended ceiling structure (10) and a method for flowing air in connection therewith. The suspended ceiling structure is especially intended for large-scale kitchen spaces and is formed of modular units, which comprise at least an inlet air unit (11) and an outlet air unit (18) and in an area therebetween a suspended ceiling board (25). The suspended ceiling structure comprises means producing a capture air jet (L1a), whereby the air jet may be brought to flow in the direction of a plane (T) of the suspended ceiling board (25) toward an outlet air opening (20) of the outlet air flow (L₂), whereby the capture air flow (L1a) draws an impure air and/or excess heat or excess moisture risen from the the impurity source of the room space toward the outlet air unit (18). The suspended ceiling structre (10) comprises such means producing the capture air jet (L1a), the air-flow dischage opening (D) of which means is located essentially directly in the vicinity of a surface plane (25') of the suspended ceiling board (25) and that the means producing the capture air jet (L1a) comprise an air guiding surface (27a'), which orientates the air jet such that it flows in the direction of the plane (T) of the suspended ceiling board (25) toward the outlet air chamber (19) of the outlet air unit (18).
