<p>The system recovers heat-transmission losses in private houses, greenhouses and other buildings. Air is blown via conduits and chambers formed in building components to the peripheral surfaces of the building, where it flows through gaps and in the process takes up heat radiated from the heated rooms. It is then sucked into a collector passage, and delivered to a heat-extraction unit, from which it is directed to the peripheral surfaces again. Air circulation can be fan-assisted.</p> |
