The system is for heat recovery from outgoing ventilation air and waste water, the air being caused to take in heat from the water by means of a heat exchanger before it is applied as a heat carrier to a heat pump. Ingoing ventilation air is heated by heat exchange with the outgoing air before the latter is fed to the heat exchanger. The system enables the major part of the heat content of discharge air and waste water to be recovered and used without any hygienic problem. |
