A ventilation device comprises a body (11) having first and second ports (14, 15) and a ventilation passage (13) that extends through the body between the ports to allow airflow through the body. The ventilation device also comprises a noise attenuation device (21) arranged to attenuate noise transmission through the passage in at least one direction from the first to the second port. The noise attenuation device comprises at least one array (22, 23) of noise attenuation tubes disposed in the ventilation body. In one form, the noise attenuation device (21) include two arrays of attenuator tubes disposed on respective opposite sides of the passage (13). The tubes each have a mouth (27) that opens to the passage and a central axis that extends from the mouth in the direction of elongation of that tube. At least some of the tubes in the first array (20) oppose at least some of the tubes in the second array (23) with the central axes of the opposing tubes at the region of their mouths (27) being mutually inclined. In addition, at least one of the arrays include an acoustic transmissive partition (30) associated with at least some of the attenuator tubes. The partition (30) separates at least a portion of the cavities (28) of those tubes (27) from the ventilation passage (13). A framing system (40) is also disclosed to enable a bank of ventilation devices (41, 101) to be interconnected and coupled within a frame (60), particularly a glazing frame.
A ventilation device comprising a body having first and second ports, a ventilation passage extending through the body between the ports to allow airflow through the body, a noise attenuation device arranged to attenuate noise transmission through the passage in at least one direction from the first to the second port, the noise attenuation device comprising first and second arrays of attenuator tubes disposed on respective opposite sides of the passage, the tubes each having a mouth that opens to the passage and a central axis extending from the mouth in the direction of the elongation of that tube, wherein at least some of the tubes in the first array opposes at least some of the tubes in the second array with the central axes of the opposing tubes at the region of their mouths being mutually inclined.
A modular structure comprising one or more modules, and coupling elements that project from the modules and which are arranged to locate within a complementary frame disposed in a supporting structure so as to connect said modular structure to said supporting structure, the modules being in the form of ventilation devices each device comprising a housing and incorporating a ventilation passage which extends through said housing.
A frame element for use in framing a structure so as to allow connection of said structure to a complementary frame of a supporting structure, the frame element having a body portion locatable against the structure and a coupling portion that projects from the body portion and is operative to locate in the complementary frame of the supporting structure.
A modular structure comprising:
A method of forming an array of inter-connectable modules mountable to a building structure, each module comprising a first part and a second part, respective first and second parts being inter-connectable to each other and to respective first and second parts of the or each adjacent module, the array of modules further comprising a frame being operative to be secured to the building structure, the method comprising the steps of:
