<p>The air conditioning unit (15) comprises an electric motor with two fans mounted on the motor spindle, one at each end. Fresh air is drawn into the house at two points. The air intake (a) provides fresh air for the living room (A). The air circulates to the next room (B) and out through the roof duct (1). A second supply of air is provided through another duct (6), and is forced by the fan through the duct (7) to the room (B). This room contains the central heating boiler (b) and requires additional combustion air. Fumes are exhausted through the chimney (bb). Other rooms are ventilated from the exhaust ducts (3,4). The air is discharged through the exhaust pipe (5) in the roof.</p> |
