Description
Selbsttätiger Regler für Kompressionskältemasshinen. Um bei Kompressionskältemaschinen einen möglichst hohen Wirkungsgrad zu erzielen, ist es notwendig, die Menge der in den Verdampfer einzuspritzenden Kälteflüssigkeit genau der wechselnden Beanspruchung der Maschine anzupassen.Automatic regulator for compression refrigeration machines. To with compression chillers To achieve the highest possible efficiency, it is necessary to adjust the amount of The refrigerant liquid to be injected into the evaporator corresponds to the changing loads adapt to the machine.
Bei der vorliegenden Erfindung werden die großen Temperaturunterschiede, welche bei wechselnder Beanspruchung der Maschine in der Druckleitung des Kompressors auftreten, zur Regelung der Einspritzmenge benutzt.In the present invention, the large temperature differences, which in the pressure line of the compressor when the machine is subjected to changing loads occur, used to regulate the injection quantity.
Auf der Zeichnung ist die Erfindung dargestellt.The invention is shown in the drawing.
Die Abbildung zeigt eine Ausführungsform, bei welcher die heißen aus dem Kompressor kommenden Dämpfe die Reglerspindel 3 in dem Hohlraum z umspülen. Der Ein- und Austritt der Dämpfe erfolgt durch die Stutzen I. Der Eintritt der Kühlflüssigkeit erfolgt durch den Stutzen 6. Durch das Ventil q. und den Stutzen 5 wird die Kälteflüssigkeit in den Verdampfer geleitet. Der Hohlraum 2 ist mit einem Kühlmantel ; umgeben. Die Reglerspindel3 erhält ein Gewinde B.The figure shows an embodiment in which the hot The vapors coming to the compressor wash the regulator spindle 3 in the cavity z. The entry and exit of the vapors takes place through the nozzle I. The entry of the cooling liquid takes place through the nozzle 6. Through the valve q. and the nozzle 5 is the cold liquid passed into the evaporator. The cavity 2 is provided with a cooling jacket; surround. the Regulator spindle3 is given a thread B.
Die zum normalen Betrieb erforderlicb#e Einstellung Wes Reglerventils erfolgt von Hand durch das Gewinde B. Schwankungen während des Betriebes machen sich sofort. durch erheb:iche Temperaturschwankungen in der Kompressionsleitung bemerkbar. Die Temperaturunterschiede betragen 4o bis 5o° C. Tritt eine Erhöhung der Temperatur gegenüber dem Normalzustand ein, so wird bei der dargestellten Ausfüh`rnng durch die Dehnung der Spindel 3 das Ventil q. weiter geöffnet, es .!rann mehr Kälteflüssigkeit in den Verdampfer strömen. Dadurch wird die Druckleitung wieder kälter, und der Regler nimmt seine Normalstellung wieder ein. Umgekehrt vollzieht sich dieser Vorgang, wenn die Druckleitung kälter wird. Um die Temperaturunterschiede voll zur Auswirkung auf das Ventil .4 kommen zu lassen, ist das äußere Gehäuse mit einem Kühlmantel? umgeben. Wird durch diesen Kühlinantel ein Kühlmittel geleitet, so nimmt das Gehäuse an der Ausdehnung nicht teil.The Wes regulator valve setting required for normal operation is done by hand through the thread B. Make fluctuations during operation immediately. due to significant temperature fluctuations in the compression line noticeable. The temperature differences are 4o to 5o ° C. If there is an increase the temperature compared to the normal state, then in the version shown the expansion of the spindle 3, the valve q. wider open, it.! more cold liquid ran down flow into the evaporator. This makes the pressure pipe colder again, and the The controller returns to its normal position. This process takes place the other way round, when the pressure pipe gets colder. To take full advantage of the temperature differences to let come on the valve .4, is the outer housing with a cooling jacket? surround. If a coolant is passed through this cooling jacket, the housing takes up does not participate in the expansion.
Bleibt z. B. das Kühlwasser aus, so dehnt sich der äußere Mantel mit dem Thermostaten gleichzeitig aus. Dadurch wird eine Eröffnung des Einspritzventils verhindert, und die Maschine läuft leer.Remains z. B. the cooling water, the outer jacket expands with it the thermostat off at the same time. This causes the injection valve to open prevented, and the machine runs idle.
Wird nun das Kühlwasser des Reglers mit dem Kühlwasser des Kondensators in Verbindung gebracht, so ist es klar, daß beim Ausbleiben des Kühlwassers im Kondensator auch der Regler kein Kühlwasser bekommt. Es tritt dann die oben beschriebene Wir= kung des Reglers ein, d. h. das Reglerventil bleibt geschlossen, und die Maschine läuft leer. Das durch den Thermostat gesteuerte Reglerventil wirkt also gleichzeitig als Sicherheit für die ganze Maschine.Now the cooling water of the controller is combined with the cooling water of the condenser connected, it is clear that in the absence of the cooling water in the condenser the controller does not get any cooling water either. The We = described above then occurs action of the controller, d. H. the regulator valve remains closed, and so does the machine runs empty. The regulator valve controlled by the thermostat thus acts at the same time as security for the whole machine.
