Long description
This is a diagramatic representation of a single storey house shown looking obliquely down on it. At the left of the diagram is a labelled living room containing a sofa. In the middle of the diagram is a labelled bathroom and at the right of the diagram is a labelled kitchen. At the top of the diagram above the ceiling is a grey box labelled ‘heat exchanger’. Coloured lines show the path for air ducts between the heat exchanger and the rooms below. A blue duct labelled ‘intake’ is shown with an arrow indicating an air flow into the heat exchanger. On the opposite side three yellow ducts emerge flowing into each of the rooms with arrows indicating the direction of air flow. Another set of ducts coloured red are shown rising from each of the rooms with small arrows showing that the direction of the flow of air is into the heat exchanger. An orange duct labelled ‘exhaust’ emerges from the opposite side of the exchanger with an arrow indicating that the air flow is outwards.
