Abstract

Die Erfindung betrifft eine Vorrichtung und ein Verfahren für eine sichere und energiesparende Spülung eines Gehäuses, das zur Aufstellung in einem Wohngebäude vorgesehen ist, und in dessen Inneren ein linksdrehender thermodynamischer Clausius-Rankine-Kreisprozess in einem geschlossenen, hermetisch dichten Arbeitsfluidumlauf (1) mittels eines entzündlichen Arbeitsfluids, welches im gasförmigen Zustand unter Atmosphärenbedingungen schwerer als Luft ist, durchgeführt wird, aufweisend mindestens einen Verdichter (2) für Arbeitsfluid, mindestens eine Entspannungseinrichtung (4) für Arbeitsfluid, mindestens zwei Wärmeübertrager (3, 5) für Arbeitsfluid mit jeweils mindestens zwei Anschlüssen (7, 8, 9, 10) für Wärmeüberträgerfluide, ein geschlossenes Gehäuse (6), welches alle am geschlossenen Arbeitsfluidumlauf angeschlossenen Einrichtungen umfasst, wobei das Gehäuse beim Anlegen von Unter- oder Überdruck dicht ist, es einen Spülluftzulauf (13) aufweist, welcher an einen Lufteinlass (12), eine Drosselungseinrichtung und eine Rückschlagsicherung (14) angeschlossen ist, es einen Spülluftauslass (26) aufweist, der an einen Ablass (22) angeschlossen ist, und der Ablass (22) an einen Ort außerhalb des Gebäudes geführt wird, zwischen dem Lufteinlass (12) und dem Spülluftauslass (26) druckseitig oder saugseitig zum Gehäuse (6) ein Fördergebläse (24) angeschlossen ist, innerhalb des Gehäuses (6) der Zulauf für den Spülluftabzug (16) an der tiefsten Stelle (15) angeordnet ist, ein Fördergebläse (24) die Spülluft fördert, die abgezogene Spülluft in mindestens einen Wärmetauscher (18, 21) geleitet wird, in dem die Spülluft gegen ein Wärmeüberträgerfluid, welches an den Kreisprozess angeschlossen ist, entweder gekühlt oder erwärmt wird.
