Die Abwärme der Wärmepumpe beheizt den Aufstellraum, der zumeist kein Wohnraum ist.The invention relates to a compression heat pump with air heat exchanger. These are operated according to the prior art such that the compression heat pump is usually housed in a building that reduces the useful heat, and the air heat exchanger is placed with its fan next to the building. The heat pump takes up space for installation. Furthermore, especially the compressor tries significant vibrations that must be damped and cause noise. The waste heat from the heat pump heats the installation room, which is usually not living space.

Ein Scharnier 9 am Gehäuse 4 verbindet den Deckel 7 mit dem restlichen Gehäuse 4; eine umlaufende Dichtung 10 dichtet den Deckel 7 mit dem restlichen Gehäuse 4 ab. Der Deckel 7 ist mit zwei Rohrleitungen 2, 3, die aus der Umgebung in das Gehäuse 4 führen, verbunden. Die beiden mindestens 1 m langen Rohrleitungen 2, 3 verfügen an ihren Öffnungen in der Umgebung über Gitter sowie eine Abdeckhaube 11 als Wetterschutz. Die erste Rohrleitung 2 führt in das Gehäuse 4 und endet unmittelbar unterhalb des Deckels 7. Der Luftwärmetauscher 1 verfügt über einen Lufteingang sowie einen Luftausgang sowie dazwischen ein Gebläse 8. Der Luftausgang des Luftwärmetauschers 1 ist mit der zweiten Rohrleitung 3 verbunden. In der zweiten Rohrleitung 3, welche mit dem Luftausgang verbunden ist, befindet sich ein Venturi 15, dessen engste Stelle mit einem flexiblen Silikonschlauch 16, der an den Boden des Gehäuses 4 führt, verbunden ist. Anschlussleitungen 12 führen von außen in das Gehäuse 4 zur Kompressionswärmepumpe 5 und dienen der Stromversorgung sowie zur Verbindung mit einem Heizsystem in einem Gebäude. Die Kompressionswärmepumpe 5 und der Luftwärmetauscher 1 sind mit einer Hebeeinrichtung 13, 14 verbunden.A
Zur Installation wird das Gehäuse 4 sowie im Erdreich 6 eingegraben, dass zumindest der Deckel 7 noch aus dem Erdreich 6 schaut. Der Deckel wird zur Installation und Demontage zur Seite geklappt (vergleiche
Beim Betrieb der Kompressionswärmepumpe 5 läuft das Gebläse 8 des Luftwärmetauschers 1 an. Luft aus dem Gehäuse 4 wird angesaugt und über den Luftausgang sowie die zweite Rohrleitung 3 in die Umgebung geblasen. Hierdurch entsteht ein Unterdruck im Gehäuse 4, so dass Luft aus der Umgebung über die erste Rohrleitung 2 zunächst in das Gehäuse 4 strömt und dann über den Lufteintritt des Luftwärmetauschers 1 angesaugt wird, um dort Wärme abzugeben. Die aufgenommene Wärme wird in der Kompressionswärmepumpe 5 aufgenommen und auf Heizniveau gebracht. Die Nutzwärme wird über die Heizungsleitungen der Anschlussleitungen 12 in ein Gebäude geleitet.During operation of the
Der Venturi 15 sorgt durch die Umwandlung von statischen in dynamischen Druck an seiner engsten Stelle für Unterdruck, so dass über den Silikonschlauch 16 eventuell vorhandenes Kondensat vom Boden des Gehäuses 4 angesaugt wird. Dieses Kondensat wird im Venturi 15 in die abgeführte Luft eingedüst und in die Umgebung abgeführt.The Venturi 15 provides by the conversion of static into dynamic pressure at its narrowest point for negative pressure, so that over the
Die Dichtung 10 zwischen Deckel 7 und Gehäuse 4 verhindert den Eintritt von Feuchte und Schmutz; die Gitter den Eintritt von Tieren. Durch den Luftaustausch wird Feuchte, die sich bei Stillstand ansammeln kann, im Luftstrom aufgenommen.The
Alternativ zum Venturi 15 mit Silikonschlauch 16 kann eine nicht dargestellte Kondensatleitung mit Kondensatpumpe für die Kondensatabführung vorgesehen sein.As an alternative to Venturi 15 with
Die Hebevorrichtung kann alternativ oder zusätzlich über eine Feder verfügen. Die Kompressionswärmepumpe 5 mit Luftwärmetauscher 1 wird dann an der Hebevorrichtung befestigt und gegen die Feder nach unten gedrückt und am Boden mittels eines Schnappverschlusses oder einer Schraube fixiert. Zum Ausbau oder Wartung wird dann die Fixierung gelöst, so dass durch die Federkraft die Kompressionswärmepumpe 5 mit Luftwärmetauscher 1 nach oben gedrückt wird.The lifting device may alternatively or additionally have a spring.
