Abstract

In dem Kältemittelkreislauf befindet sich eine durch das Kältemittel angetriebene Expansionsmaschine in Baueinheit mit einem Ventilator, der veränderliche Rotorblattstellung aufweist. Durch die Rückwirkung dieser Bauteile wird das Steuerdiagramm des Ventilators auf optimale Verhältnisse entsprechend des Kennlinienfeldes eingestellt, womit sich eine ideale Leistungsanpassung ergibt.In the refrigerant circuit there is an expansion machine driven by the refrigerant in a structural unit with a fan which has variable rotor blade positions. Due to the reaction of these components, the control diagram of the fan is set to optimal conditions according to the characteristic field, which results in an ideal performance adjustment.

Description

Die Erfindung betrifft eine kompressionskältemaschine bzw. -wärmepumpe nach dem Oberbegriff des einzigen Anspruchs.The invention relates to a compression refrigeration machine or heat pump according to the preamble of single claim.

Kompressionskältemaschinen weisen einen Verdichter, der den kältemitteldampf aus einem Verdampfer ansaugt und auf den Kohdensätordrück verdichtet, Und einen Kondensator, in dem der verdichtete Dampf Unter Wärmeabgabe an die Umgebung verflüssigt wird, auf. Das nun flüssige Kältemittel strömt durch ein Drosselorgan, welches den Druckausgleich zwischen kondensator und Verdampfer verhindert und in dem das Kältemitte! auf niedrigen Druck entspannt wird, in deii Verdampfer. Hier verdampft das Kältemittel und entzieht der Umgebung Wärme, wobei der Betrag der der Umgebung entzogenen Wärme bei Luftdurchströmuhg von der Menge der den Vecdampfc" durchströmenden Luft abhängig istCompression refrigeration machines have a compressor, which sucks in the refrigerant vapor from an evaporator and compresses it to the Kohdensätordruck, and a condenser in which the compressed vapor is liquefied while releasing heat into the environment. The now liquid refrigerant flows through a throttle element, which balances the pressure between the condenser and evaporator prevented and in which the refrigerant! is expanded to low pressure in the evaporator. Here the refrigerant evaporates and removes heat from the surroundings, the amount being that of the surroundings withdrawn heat with air flow of the amount of air flowing through the vapor is dependent

Eine Kompressionskälteriiascb re bzw. -wärmepumpe der eingangs genannten Art ist aus der US-PS 4 170 i 16 bekannt wobei die in der Expansionsmaschine gewonnene mechanische Energie zum Betrieb einer Pumpe benutzt wird, die in dem Kreislauf des Kältemittels liegt und zur Steigerung des statischen Drucks des Kältemittels dient. Eine entsprechende Vorrichtung, beider die Entspannung des Kühlmediums zum Antrieb eines Gebläses verwendet wird, ist aus der AT-?S 29 55 64 bekanntA compression refrigeration valve or heat pump of the type mentioned above is known from US Pat. No. 4,170,116, the expansion machine The mechanical energy obtained is used to operate a pump in the refrigerant circuit and is used to increase the static pressure of the refrigerant. An appropriate device, both the expansion of the cooling medium is used to drive a fan is from the AT-? S 29 55 64 known

Der Erfindung liegt die Aufgabe zugrunde, die in der Expansionsmaschine gewonnene mechanische Energie zur Regelung des Luftdurchsatzes durch den Verdampfer der Wärmepumpe zu nutzen.The invention is based on the object of the mechanical energy obtained in the expansion machine to control the air flow through the evaporator of the heat pump.

Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil des einzigen Anspruchs angegebenen Merkmale gelöstAccording to the invention, this object is given by those specified in the characterizing part of the single claim Features solved

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der die Erfindung anhand einer Zeichnung erläutert wird. Dabei zeigtFurther features and advantages of the invention emerge from the following description in which the Invention is explained with reference to a drawing. It shows

Bei der in F i g. 1 dargestellten Kompressionskältemaschine tritt das Kältemedium bei 1 in die Expansionsmaschine 4 ein, durch eine geeignete Übersetzung 7 ein Gebläse 5 antreibt. Das nach Verlassen der Expansionsmaschine 4 entspannte Kältemedium tritt nach Passieren der Wärmetauscherschlangen 6 in dem Gehäuse 3 bei 2 aus.In the case of the in FIG. 1, the cooling medium enters the expansion machine at 1 4, a fan 5 drives through a suitable transmission 7. That after leaving the expansion machine 4 relaxed cooling medium enters the housing 3 after passing through the heat exchanger coils 6 at 2 off.

Das Gebläse 5 bewirkt dabei, wie F i g. 2 verdeutlicht, eine gesteigerte Luftdurchströmung durch das die Wär-Hierzü i Blatt ZeichnungenThe fan 5 has the same effect as FIG. 2 shows an increased flow of air through the heat i sheet drawings
