Beschreibung des Ausführungsbeispielsdescription of the embodiment

Ein nicht näher dargestelltes Niedrigenergie-Haus ist mit einer Wärmekraftmaschine 30 ausgerüstet, zu der ein luftgekühltes Wechsel-Aggregat 1 gehört, das in der Abluft des Hauses angeordnet ist. In der Zuluft zum Haus befindet sich ein ebenfalls luftgekühltes Wechsel-Aggegat 2. Es ist ein wesentliches Merkmal der Erfindung, dass diese beiden Wechsel-Aggregate 1 und 2 derart in Wechselwirkung arbeiten, dass sie einmal als Verdampfer und einmal als Kondensator wirken. Zum Erreichen dieser Wechselwirkung ist ein Teilkreis-Umkehrventil 6 installiert, das als 4/2-Wege-Magnetventil ausgebildet ist.A low-energy house, not shown, is with a heat engine 30 equipped with an air-cooled interchangeable unit 1 heard, which is arranged in the exhaust air of the house. In the supply air to the house there is also an air-cooled exchange unit 2 , It is an essential feature of the invention that these two interchangeable units 1 and 2 interact in such a way that they act once as an evaporator and once as a condenser. To achieve this interaction is a partial circle reversing valve 6 installed, which is designed as a 4/2-way solenoid valve.

Desweiteren gehört zur Wärmekraftmaschine 30 ein Kältemittelverdichter 3, dessen Drehzahl stetig variabel regelbar ist. Im Erdreich oder im Grundwasser befindet sich ein Direktverdampfer 4 zur Aufnahme der Primärenergie. Ein wassergekühlter, Direktkondensator 5 ist in einem Multifunktions-Pufferspeicher 24 angeordnet, der einen Elektroheizstab 28 zu Notbetnebszwecken, einen Frischwasser-Wärmeübertrager 23 und einen Solar-Wärmeübertrager 22 aufnimmt, wobei Letzterer von einem thermischen Solarabsorber 21 gespeist wird.Furthermore belongs to the heat engine 30 a refrigerant compressor 3 , whose speed is continuously variable. There is a direct evaporator in the ground or in the groundwater 4 to absorb primary energy. A water-cooled, direct condenser 5 is in a multi-function buffer memory 24 arranged of an electric heating element 28 for emergency purposes, a fresh water heat exchanger 23 and a solar heat exchanger 22 records, the latter from a thermal solar absorber 21 is fed.

An einem der vier Anschlüsse des Teilkreis- Umkehrventils 6 ist ein Kältemittel-Sauggasdruckbegrenzer 10 angeschlossen, der Verbindung mit der Saugseite des Kältemittel-Verdichters 3 und mit einem hinter dem Direktverdampfer 4 liegenden Kältemittel-Rückschlagventils 20 hat. Andererseits ist der Direktverdampfer 4 über ein Kältemittel-Expansionsventil 11 und ein Kältemittel-Flüssigkeitsmagnetventil 16.1 und ein Kältemittel- Trockner 8 samt Schauglas 9 an die zwei Aggregate 1 und 2 angeschlossen. In dieser Verbindung ist ein zentraler Kältemittelsammler 7 angeordnet, der einerseits mit dem wassergekühlten, direkten Kondensator 5 im Pufferspeicher 24 und anderseits mit den Wechsel-Aggregaten 1 und 2, in der jeweiligen Wechselwirkung, so wie mit dem Direktverdampfer 4, verbunden ist.On one of the four connections of the partial circuit reversing valve 6 is a refrigerant suction gas pressure limiter 10 connected, the connection to the suction side of the refrigerant compressor 3 and with one behind the direct evaporator 4 horizontal refrigerant check valve 20 Has. On the other hand is the direct evaporator 4 via a refrigerant expansion valve 11 and a refrigerant liquid solenoid valve 16.1 and a refrigerant dryer 8th including sight glass 9 to the two units 1 and 2 connected. In this connection there is a central refrigerant collector 7 arranged the one hand with the water-cooled, direct condenser 5 in the buffer memory 24 and on the other hand with the interchangeable units 1 and 2 , in the respective interaction, as with the direct evaporator 4 , connected is.

Zwischen den beiden Wechsel-Aggregaten 1 und 2 liegt ein weiteres Kältemittel-Expansionsventil 17 das der Abluft beigeordnet ist. Das Gleiche gilt auch für das Flüssigkeits-Magnetventil 14 und das Kältemittel-Expansionsventil 13, das der Zuluft beigeordnet ist.Between the two interchangeable units 1 and 2 there is another refrigerant expansion valve 17 that is assigned to the exhaust air. The same applies to the liquid solenoid valve 14 and the refrigerant expansion valve 13 which is assigned to the supply air.

Desweiteren befindet sich am Multifunktions-Pufferspeicher 24 ein Anschluss für einen geregelten Heizkreismischer 26, die Heizkreiszonenventile 25 und die Heizkreise 27 einer nicht dargestellten Niedertemperatur-Heizung.There is also a multi-function buffer memory 24 a connection for a regulated heating circuit mixer 26 , the heating circuit zone valves 25 and the heating circuits 27 a low-temperature heater, not shown.

Das Wechsel-Aggregat 1 hat einen Anschluss für ein Kältemittel-Rückschlagventil 15 für die Abluft und das Wechselaggregat 2 hat einen Anschluss für ein Kältemittel-Rückschlagventil 12 für die Zuluft.The interchangeable unit 1 has a connection for a refrigerant check valve 15 for the exhaust air and the exchange unit 2 has a connection for a refrigerant check valve 12 for the supply air.

Eine Kältemittel- Sauggasumgehung trägt die Bezugszahl 29, ein Kältemittel-Kondensationsdruckbegrenzungs-Ventil ist mit der Bezugszahl 18 versehen und eine elektronische Steuerung, eine sogenannte Blackbox für alle Magnetventile für die Heizkreise und den Elektroheizstab 28 , ist mit der Bezugszahl 31 bezeichnet.A refrigerant suction gas bypass bears the reference number 29 , a refrigerant condensation pressure relief valve is with the reference number 18 and an electronic control, a so-called black box for all solenoid valves for the heating circuits and the electric heating element 28 , is with the reference number 31 designated.

Wirkungsweiseoperation

Ein Kältemittel-Magnetventil 16 liegt in der Zuluft.A refrigerant solenoid valve 16 lies in the supply air.

Ein Kältemittel-Magnetventil 16.1 liegt in der Erdreichverbindung. Und ein Kältemittel – Magnetventil 16.2 ist dem direkten, wassergekühlten Kondensator zugeordnet.A refrigerant solenoid valve 16.1 lies in the ground connection. And a refrigerant solenoid valve 16.2 is assigned to the direct, water-cooled condenser.

Wenn die Wärmekraftmaschine 30 arbeitet, gelangt Kältemittel in flüssigem Zustand über den Kältemittel-Trockner 8 in das Kältemittel – Schauglas 9 zu den beiden Kältemittel – Flüssigkeitsmagnetventilen 16 und 16.1 Über die beiden Kältemittel – Expansionsventile 11 und 17 expandiert das Kältemittel und verdampft sowohl im Direktverdampfer 4 als auch im luftgekühlten Lamellenverdampfer des Wechsel-Aggregats 1.If the heat engine 30 works, refrigerant in the liquid state passes through the refrigerant dryer 8th into the refrigerant sight glass 9 to the two refrigerant liquid solenoid valves 16 and 16.1 Via the two refrigerant expansion valves 11 and 17 expands the refrigerant and evaporates both in the direct evaporator 4 as well as in the air-cooled finned evaporator of the interchangeable unit 1 ,

Das verdampfte Kältemittel vom Direktverdampfer 4 und das vom Lamellenverdampfer 1 wird vom Kältemittel – Verdichter 3 angesaugt. Die beiden Verdampfer 4 und 1 können einzeln und unabhängig voneinander betrieben werden. Die jeweilige Freigabe erfolgt über die beiden Kältemittel – Flüssigkeitsmagnetventile 16 und 16.1.The evaporated refrigerant from the direct evaporator 4 and that from the finned evaporator 1 is used by the refrigerant compressor 3 sucked. The two evaporators 4 and 1 can be operated individually and independently of each other. The respective release takes place via the two refrigerant liquid solenoid valves 16 and 16.1 ,

Nach der Verdichtung des angesaugten Kältemitteldampfes im Kältemittel – Verdichter 3 gelangt das Kältemittel zu den Kondensatoren 5 und 2 . Die Verflüssigung des überhitzten Kältemitteldampfes findet sowohl im wassergekühlten Kondensator 5 als auch in dem von Zuluft gekühlten Kondensator statt. Das wieder verflüssigte Kältemittel gelangt dann zurück in den Kältemittelsammler 7. So weit arbeitet die Wärmekraftmaschine 30 ganz normal. Gemäß der vorliegenden Erfindung besteht nun der gesamte Kältemittelkreislauf aus zwei parallelen und unabhängig voneinander arbeitenden Wechsel-Aggregaten 1 und 2 aus Verdampfern und Kondensatoren, wobei die beiden Wechsel-Aggregate 1 und 2 mit ihren Verdampfern und Kondensatoren über das Teilkreis-Umkehrventil 6 so functional verändert werden, dass der Verdampfer zu einem Kondensator und der Kondensator zu einem Verdampfer umschaltet. Dagegen bleiben der Verdampfer 4 und der Kondensator 5 unverändert.After compression of the sucked refrigerant vapor in the refrigerant compressor 3 the refrigerant reaches the condensers 5 and 2 , The superheated refrigerant vapor is liquefied both in the water-cooled condenser 5 as well as in the condenser cooled by supply air. The re-liquefied refrigerant then gets back into the refrigerant collector 7 , So far the heat engine works 30 absolutely normal. According to the present invention, the entire refrigerant circuit now consists of two parallel and independently working change units 1 and 2 from evaporators and condensers, the two interchangeable units 1 and 2 with their evaporators and condensers via the partial circuit reversing valve 6 so functional that the evaporator switches to a condenser and the condenser to an evaporator. In contrast, the evaporator remains 4 and the capacitor 5 unchanged.

Das Wechsel-Aggregat 1 mit seinem Verdampfer kann im Kältekreislauf mit dem vorzugsweise in der Erde angeordneten Direktverdampfer 4 und auch in der Wechselwirkung mit dem Verdampfer des Wechsel-Aggregat 2 zusammengeschaltet werden.The interchangeable unit 1 with its evaporator can in the refrigeration cycle with the direct evaporator preferably arranged in the ground 4 and also in the interaction with the evaporator of the interchangeable unit 2 be interconnected.

Bei der Kondensation kann hingegen der Kondensator vom Wechsel-Aggregat 1 mit dem direkt wassergekühlten Kondensator 5 und auch in der Wechselwirkung mit dem Kondensator des Wechsel-Aggregats 2 zusammengeschaltet werden.In the case of condensation, on the other hand, the condenser from the alternating unit 1 with the directly water-cooled condenser 5 and also in the interaction with the capacitor of the alternating unit 2 be interconnected.

Durch die besondere Schaltweise und durch das Vorhandensein der beiden Wechsel-Aggregate 1 und 2 mit zwei Verdampfersystemen ist es möglich, stets die maximale Verdampfungstemperatur und auf der Kondensatorseite die wirtschaftlichste Kondensationstemperatur zu erreichen. Und das mit der zusätzlichen Option, dass der unveränderte, wassergekühlte Kondensator 5 auch als reiner Enthitzer, in Reihenschaltung durch das Schließen des Magnetventils 16.2, arbeiten kann. Durch seine Anordnung im Multifunktions-Pufferspeicher 24 und Einbindung in den Kältekreis wird seine Wärmeenergie jeweils optimal ausgenutzt.Due to the special switching method and the presence of the two interchangeable units 1 and 2 With two evaporator systems it is possible to always reach the maximum evaporation temperature and the most economical condensation temperature on the condenser side. And with the additional option that the unchanged, water-cooled condenser 5 also as a pure desuperheater, connected in series by closing the solenoid valve 16.2 , can work. Due to its arrangement in the multifunction buffer memory 24 and integration into the refrigeration circuit, its thermal energy is optimally used.
