Abstract

Lubricant for refrigerant compressors with ammonia as refrigerant comprising an alcohol oxypropylate with a mol. wt. of 800-1700 g/mol. or a mixt. of these.

Description

Die Erfindung betrifft die Verwendung von Polyglykol als Schmiermittel für Kältemittelverdichter, die mit Ammoniak als Kältemittel betrieben werden.The invention relates to the use of polyglycol as Lubricant for refrigerant compressors with ammonia as Refrigerants are operated.

In Ammoniak-Kälteanlagen werden vorrangig Schmierstoffe für den Verdichter verwendet, die mit dem Kältemittel unlöslich sind. Solche Stoffe sind Mineralöle, Alkylbenzol und Polyalphaolefine. Diese Öle werden vom Verdichter mit dem geförderten Ammoniak- Gasstrom in unvermeidlicher Weise in den Kältekreislauf ver­ schleppt. Sie scheiden sich vorwiegend an Stellen mit geringer Strömungsgeschwindigkeit ab. Von dort kann das Öl, welches schwerer als Ammoniak ist, entnommen und mit besonderen Einrich­ tungen in den Verdichter zurückgeführt werden.Ammonia refrigeration systems primarily use lubricants for the Compressors used that are insoluble with the refrigerant. Such substances are mineral oils, alkylbenzene and polyalphaolefins. These oils are produced by the compressor with the pumped ammonia Gas flow inevitably ver in the refrigeration cycle drags. They mainly differ in places with less Flow rate. From there the oil, which heavier than ammonia, removed and with special equipment lines are returned to the compressor.

Um auf diese besonderen aufwendigen Einrichtungen verzichten zu können ist es bekannt, die Viskosität des Schmiermittels und seine Löslichkeit mit Ammoniak so zu wählen, daß es aus allen Anlagenteilen, insbesondere aus dem Verdampfer, mit dem Ammoniak-Gasstrom in den Verdichter zurückgeführt werden kann. Als geeignete Stoffe wurden Polyglykole (DE 23 45 540) und Polylakylenglykole (EP 490 810 A1) vorgeschlagen, die mit dem Ammoniak löslich sind und die Viskosität dieses Gemisches die gewünschten Eigenschaften hat.To dispense with these special elaborate facilities it is known the viscosity of the lubricant and choose its solubility with ammonia so that it is out of all Plant parts, especially from the evaporator, with the Ammonia gas flow can be returned to the compressor. Polyglycols (DE 23 45 540) and Polylakylene glycols (EP 490 810 A1) proposed with the Ammonia are soluble and the viscosity of this mixture desired properties.

Diese Stoffe haben aber auch einige für die Verwendung als Schmiermittel in Kälteanlagen mit Ammoniak als Kältemittel uner­ wünschte Eigenschaften. So sind Polyalkylenglyklole in hohem Maße hygroskopisch, was sich sehr störend in Kälteanlagen, ins­ besondere solchen größere Leistung auswirkt, die beispielsweise zu Wartungs- und Reparaturarbeiten geöffnet werden müssen. Man hat deshalb vorgeschlagen, Ester der Zitronensäure als Schmier­ mittel zu verwenden (DE 42 09 502 A1), wobei über die Eignung zusammen mit Ammoniak nichts gesagt ist. Ein weiterer Nachteil ist darin zu sehen, daß viele Polyglykole nicht mit Ölen auf Kohlenwasserstoffbasis löslich sind, was beim Wechseln der Öl­ sorte zu einem erheblichen Reinigungs- und Entsorgungsaufwand führt.However, these fabrics also have some for use as Lubricants in refrigeration systems with ammonia as a refrigerant are essential desired properties. So polyalkylene glycols are high  Dimensions hygroscopic, which is very annoying in refrigeration systems, ins special impact such greater performance, for example must be opened for maintenance and repair work. Man has therefore proposed esters of citric acid as a lubricant medium to use (DE 42 09 502 A1), with the suitability nothing is said together with ammonia. Another disadvantage can be seen in the fact that many polyglycols do not contain oils Hydrocarbon base are soluble when changing the oil variety for a considerable cleaning and disposal effort leads.

Aufgabe der Erfindung ist es, Schmiermittel aus der Reihe der Poyglykole anzugeben, welche die Forderungen bezüglich der Ammoniaklöslichkeit, der Viskosität und Mischbarkeit mit Kohlen­ wasserstoffen bei gleichzeitiger Unlöslichkeit in Wasser er­ füllen.The object of the invention is to provide lubricants from the range Poyglykole specify the requirements regarding the Ammonia solubility, viscosity and miscibility with coal Hydrogen with insolubility in water to fill.

Erfindungsgemäß wird die Aufgabe durch zwei Wege gelöst.According to the invention, the object is achieved in two ways.

Im ersten Lösungsweg ist das Schmiermittel ein Alkoholoxypropy­ lat mit einer molaren Masse von 800 bis 1700 g/mol.In the first solution, the lubricant is an alcohol oxypropy lat with a molar mass of 800 to 1700 g / mol.

Im zweiten Lösungsweg ist das Schmiermittel eine Mischung ver­ schiedener Alkholoxypropylate mit molaren Massen zwischen 800 und 1700 g/mol.In the second solution, the lubricant is a mixture Different alcohol oxypropylates with molar masses between 800 and 1700 g / mol.

Diese Stoffe haben ausreichende Schmiereigenschaften für den Verdichter, wie eingehende Versuche ergeben haben. Sie sind sowohl mit Ammoniak als auch mit Mineralölen in gewünschter Weise mischbar. Sie zeigen ferner keine gefährlichen Reaktionen. Die Zündtemperatur liegt über 300° Celsius, so daß ein gefahrloser Einsatz in Kälteanlagen möglich ist. These substances have sufficient lubricating properties for the Compressors, as detailed tests have shown. you are both with ammonia and with mineral oils in the desired way miscible. They also show no dangerous reactions. The Ignition temperature is over 300 ° Celsius, making it a safe one Use in refrigeration systems is possible.  

In Weiterentwicklung der Erfindung können durch Beifügen von Alkylbenzol die Eigenschaften des Polyalkylenglykols sowohl als Einzelstoff oder auch als Mischung verschiedener Polyalkylen­ glykole in weiten Grenzen beeinflußt werden.In further development of the invention, by adding Alkylbenzene has the properties of both polyalkylene glycol Single substance or as a mixture of different polyalkylene glycols can be influenced within wide limits.

Nach einer anderen Weiterentwicklung können auch durch Beifügen von Mineralöl die Eigenschaften von Polyglykolen den Erforder­ nissen angepaßt werden, soweit sie damit mischbar sind.Another development can also be done by adding of mineral oil the properties of polyglycols the requirements nissen be adjusted as far as they are miscible with it.

Durch die Erfindung wird gezeigt, wie bei Kälteanlagen mit Ammoniak als Kältemittel für fast alle Einsatzfälle ein zuge­ schnittenes Schmiermittel geschaffen werden kann.The invention shows how with refrigeration systems Ammonia as a refrigerant for almost all applications cut lubricant can be created.

Durch entsprechende Wahl eines Alkoholoxypropylat oder einer Mischung verschiedener Alkoholoxypropylate kann das Schmier­ mittel den Einsatzbedingungen der Kälteanlage angepaßt werden. Durch den Zusatz von Alkylbenzol und/oder Mineralölen kann eine weitere Anpassung des Schmiermittels erfolgen. So erfordert zum Beispiel der Tieftemperaturbereich ein Schmiermittel, wel­ ches auch bei tiefen Temperaturen aus dem Verdampfer in den Verdichter zurückgeführt werden kann. Im Klimabereich wiederum muß das Schmiermittel an die hohen Saugdrücke angepaßt sein.By appropriate choice of an alcohol oxypropylate or Mixing different alcohol oxypropylates can make the lubrication be adapted to the conditions of use of the refrigeration system. By adding alkylbenzene and / or mineral oils the lubricant is adjusted further. So requires for example the low temperature range a lubricant which wel ches even at low temperatures from the evaporator in the Compressor can be returned. In the climate area, on the other hand the lubricant must be adapted to the high suction pressures.

Wird zum Beispiel die Löslichkeit von Mineralöl gewünscht, kann durch ein entsprechendes Alkolholoxypropylat diese Wirkung er­ zielt werden. Dadurch können Kälteanlagen, die bisher mit Mineralöl als Schmiermittel betrieben wurden, ohne aufwendige Reinigungsarbeiten auf ein Schmiermittel auf Glykolbasis umge­ stellt werden.For example, if the solubility of mineral oil is desired, can by an appropriate alcohol oxypropylate he this effect aims to be. This allows refrigeration systems that were previously used Mineral oil was operated as a lubricant without being expensive Cleaning work on a lubricant based on glycol reversed be put.
