Ambient air is drawn into the intake chamber (ABC) through an air-permeable insulation layer (10) in an external wall opening. The insulation layer (10) with supports (11) forms an outer wall (1) of the intake chamber and is spaced from the inner wall (3) by four perimeter sides. The inner wall includes outlet openings (6) to the collection box (5) and distribution ducting (9). An air distribution baffle membrane (2) between the insulation wall (1) and the inner wall (3) is fixed under a batten layer (12). The membrane (2) is sized to allow an air path all round. The inner chamber wall (3) is fixed to a second batten layer (13) at right angles to the layer (12). |
