Description

Es ist üblich, bei einer Gebäudelüftungsanlage die Wärmeenergie aus der Abluft mittels eines Wärmetauschers auf die Zuluft zu übertragen. Je effizienter der Wärmetauscher ist, desto weniger Zusatzenergie müssen für die Erwärmung der hygienisch notwendigen Zuluftmenge aufgebracht werden.It is customary in a building ventilation system to transfer the heat energy from the exhaust air by means of a heat exchanger to the supply air. The more efficient the heat exchanger, the less additional energy must be applied for heating the hygienically necessary supply air.

Es ist weiterhin üblich, mittels Solarkollektoren, Luftkollektoren und/oder Geothermiekollektoren (Erdkollektoren) rekuperativ gewonnene Wärmeenergie mittels Verdampfern und einer Wärmepumpe zur Erwärmung von Brauchwasser und/oder als Ergänzung der Gebäudebeheizung zu verwenden. Häufig werden Heizsysteme wie Elektroheizkörper, Gasthermen oder aber auch Wärmepumpen mit wasserdurchströmten Lufterhitzern nachgeschaltet. Die Brauchwasserbereitung wird üblicherweise wiederum getrennt mit einem Elektroheizstab oder indirekt aus den externen Wärmeerzeugern bewirkt.It is also customary to use by means of solar collectors, air collectors and / or geothermal energy collectors (earth collectors) recuperatively recovered heat energy by means of evaporators and a heat pump for heating domestic water and / or as a supplement to the building heating. Frequently, heating systems such as electric radiators, gas water heaters or even heat pumps are followed by air heaters with water flow. The hot water preparation is usually again effected separately with an electric heater or indirectly from the external heat generators.
