Description

Beschreibung:Description:

Die Erfindung bezieht sich auf einen rekuperativen Wärmerückgewinner mit handelsüblichen Kreuzstrom-Plattentauscher-Elementen 2, eingebaut in ein Gehäuse 1 zur Wärmerückgewinnung aus Fortluft oder Abgasen etc.The invention relates to a regenerative heat exchanger with commercially available cross-flow plate exchanger elements 2, installed in a housing 1 for heat recovery from exhaust air or exhaust gases etc.

Der Fort- und Außenluftstrom wird so geführt, daß hintereinander angeordnete Kreuzstrom-Plattentauscher nicht in Reihe, sondern parallel von den beiden Luftströmen beaufschlagt werden. Hierbei stellt sich bei einem guten Wärmerückgewinnungsgrad ein geringer Druckverlust ein.The exhaust and outside air flow is guided so that one behind the other Cross-flow plate heat exchangers not in series, but in parallel with the two air flows be applied. This arises with a good degree of heat recovery a slight pressure loss.

Rekuperative Wärmerückgewinner der genannten Art werden üblicherweise mit einer entsprechenden Anzahl Tauscher-Würfel so hintereinander geschaltet, daß sich mindestens der doppelte Druckverlust ergibt und die doppelte Anzahl Tauscherwürfel benötigt werden.Recuperative heat recovery systems of the type mentioned are usually used with a corresponding number of exchanger cubes connected in series so that there is at least twice the pressure loss and twice the number of exchanger cubes are needed.

In der Praxis zeigt es sich immer wieder, daß ab einer gewissen Fortluftmenge und der dazugehörenden Außenluftmenge eine derart große Anzahl Tauscherwürfel benötigt werden, daß sowohl die Anschaffungskosten sowie der sich damit ergebende Druckverlust den ganzen Aufwand in Frage stellen.In practice it turns out again and again that from a certain amount of exhaust air and the associated amount of outside air requires such a large number of exchanger cubes be that both the acquisition costs and the resulting pressure loss question all the effort.

Die Erfindung bezweckt die Herstellung eines rekuperativen Kreuzstrom-Wärmerückgewinners der durch entsprechende Luftführung 4 und Beaufschlagung der Tauscherwürfel leicht an jede Luftmenge bezüglich Wärmerückgewinnungsgrad; und Druckverlust angepasst werden kann.The invention aims to produce a recuperative cross-flow heat exchanger which is easy by means of the appropriate air duct 4 and application of the exchanger cube of each air volume with regard to the degree of heat recovery; and pressure loss adjusted can be.
