Die Wassertemperiereinrichtung 4 zur Temperierung des Prozeßwasser enthält mindestens einen Kältemittelkreislauf 10, in welchem sich in Strömungsrichtung des Kältemittels nacheinander ein Kompressor oder Verdichter 12, ein Rückschlagventil 14, ein Kältemittelkondensator 16, ein Kältemittelsammler 18, ein Kältemittel-Expansionsventil 20, ein Wärmetauscherelement 22 und dann wieder der Verdichter 12 befinden. Der Verdichter 12 verdichtet Kältemittel und bringt es dadurch von einem gasförmigen in einen flüssigen Zustand. Das Rückschlagventil 14 verhindert einen Rückfluß von Kältemittel vom Kältemittelkondensator 16 in den Verdichter 12. Im Kältemittelkondensator 16 kondensiert Kältemittel. Die dabei frei werdende Wärme wird von der Kühlluftgebläseeinrichtung 6 aus dem Geräteschrank nach oben abgeführt. Die Kühlluftgebläseeinrichtung 6 saugt Luft 23 von der Außenatmosphäre durch eine Lüftungsöffnung 24 in einer vorderen Schranktür 26 in den Geräteschrank und darin über den Kältemittelkondensator 16 oder durch in ihm gebildete Durchlaßöffnungen hindurch, wonach die erwärmte Luft durch die Kühlluftgebläseeinrichtung 6 hindurch strömt und von ihr gemäß einem Pfeil 28 nach oben aus dem Geräteschrank ausgestoßen wird. Hierzu kann der Geräteschrank oben offen sein oder mit einer oder mehrerer Entlüftungsöffnungen versehen sein. Im Kältemittelsammler 18 kann sich kondensiertes Kältemittel ansammeln.

Die schweren Teile wie Verdichter 12 und Sammler 18 befinden sich in der untersten Etage. Dadurch hat der Geräteschrank einen tiefen Schwerpunkt und damit eine gute Standfestigkeit. Der Geräteschrank kann somit gewichtsmäßig verhältnismäßig leicht ausgebildet werden, weil er nicht die zum Tragen dieser schweren Teile erforderliche Stabilität benötigt. Der Geräteschrank hat vorzugsweise keine Füße, so daß der Schrankboden 58 der untersten Etage 41 unmittelbar auf dem Fußboden liegt. Der Konditionierbehälter 8 ist, wenn er Prozeßwasser enthält, zwar ebenfalls schwer, jedoch immer noch auf einer so geringen Höhe, daß der Gehäuserahmen 46 des unteren Gehäuses 48 nur bis zu dieser niedrigen Höhe entsprechend stabil und schwer ausgebildet sein muß. Ein großer Vorteil ist auch, daß der Konditionierbehälter 8 auf einer Höhe liegt, die es einer Bedienungsperson bequem ermöglicht, den Behälterinhalt zu inspizieren, den Konditionierbehälter 8 bei Bedarf herauszunehmen und wieder einzusetzen, und die für die Konditionierung des Prozeßwassers erforderlichen elektrischen, hydraulischen oder pneumatischen Geräte sowie Meßgeräte zu überprüfen und zu warten, sowie zu montieren oder auszutauschen. Zu diesem Zwecke ist der Konditionierbehälter 8 vorzugsweise zwischen Kniehöhe und Brusthöhe einer Bedienungsperson von durchschnittlicher Größe angeordnet. In der mittleren Etage 42 befindet sich im Geräteschrank, an der Schrankwand befestigt, eine Dosiereinrichtung 60 zur Zufuhr von beispielsweise Frischwasser über eine Frischwasserleitung 62, Zusatzmittel über eine Zusatzmittelleitung 64 und Alkohol über eine Alkoholleitung 66 in den Konditionierbehälter 8 in Abhängigkeit von einer elektronischen Steuereinrichtung 68, welche in der mittleren Etage 42 auf der Innenseite der Schranktür 26 befestigt ist. Die Zufuhr oder Dosierung von Frischwasser, Zusatzmittel und Alkohol erfolgt in Abhängigkeit von Sensoren, welche im Konditionierbehälter 8 die Wasserstandshöhe, den Gehalt an Zusatzmitteln und den Gehalt an Alkohol konstant messen und an die elektronische Steuereinrichtung 68 und/oder an die Dosiereinrichtung 60 melden. In Fig. 1 sind hierfür schematisch ein Flüssigkeitspegelsensor 70, ein Alkoholsensor 72 und ein Sensor 74 für Zusatzmittel dargestellt. Die Dosiereinrichtung 60 enthält Dosiergeräte und Ventile.The heavy parts like compressor 12 and collector 18 are located on the bottom floor. As a result, the Equipment cabinet a low center of gravity and thus a good stability. The equipment cabinet can thus relatively light weight be because he's not the one to carry this heavy Parts required stability required. Of the Device cabinet preferably has no feet, so that the Cupboard floor 58 of the bottom floor 41 immediately on the floor. The conditioning container 8 is if it contains process water, also heavy, however still at such a low level that the Housing frame 46 of the lower housing 48 only up to corresponding to this low height stable and heavy must be trained. Another big advantage is that the conditioning container 8 is at a level that it an operator conveniently allows Inspect the contents of the container, the conditioning container 8 remove and reinsert if necessary, and those for conditioning the process water required electrical, hydraulic or to check pneumatic devices and measuring devices and to maintain, as well as to assemble or replace. To for this purpose the conditioning container 8 preferably between one knee and one chest Average size operator arranged. In the middle floor 42 is in Equipment cabinet, attached to the wall unit, one Dosing device 60 for the supply of, for example Fresh water via a fresh water line 62, Additive via an additive line 64 and Alcohol via an alcohol line 66 in the Conditioning container 8 depending on one electronic control device 68, which in the middle floor 42 on the inside of the cabinet door 26 is attached. The supply or dosage of Fresh water, additives and alcohol are made in Dependence on sensors, which in the Conditioning tank 8 the water level, the content of additives and the alcohol content constant measure and to the electronic control device 68 and / or report to the metering device 60. In Fig. 1 are schematically a liquid level sensor for this 70, an alcohol sensor 72 and a sensor 74 for Additives shown. The metering device 60 contains dosing devices and valves.

Es ist ein bekannter physikalischer Effekt, daß erwärmte Luft nach oben steigt. Durch die Positionierung des Kältemittel-Kondensators 16 in der obersten Etage 43 ist innerhalb des Geräteschrankes nur ein kurzer Kühlluftweg für die Kühlluft 54, 16 erforderlich. Durch die Positionierung des Kältemittel-Kondensators 16 in der obersten Etage 43 und die Positionierung des Konditionierbehälters 8 in der mittleren Etage 42, erhält man in der untersten Etage 41 einen freien Raum 76, in welchem schwere Behälter unmittelbar auf den Schrankboden 58 gestellt werden können, ohne daß der Geräteschrank verstärkt zu werden braucht und ohne daß diese schweren Behälter in eine obere Schranketage hoch gehoben werden müssen. Solche relativ schwere und relativ große Behälter können beispielsweise ein Behälter 78 für den genannten Alkohol und ein Behälter 80 für das genannte Zusatzmittel für die Zubereitung und Konditionierung des Prozeßwassers im Konditionierbehälter 8 sein. Diese Behälter 78 und 80 können Vorratsbehälter oder Behälter sein, aus welchen der Alkohol oder das Zusatzmittel von der Dosiereinrichtung 60 in den Konditionierbehälter 8 gefördert werden. Ferner können in diesem freien Raum 76 in der untersten Etage 41 Frischwasseranschlußmittel 82, Vorlauf-Anschlußmittel 84 und Rücklauf-Anschlußmittel 86 für das Prozeßwasser des Konditionierbehälters 8 angeordnet werden. Die Frischwasserleitung 62 ist über die Dosiereinrichtung 60 an die Frischwasseranschlußmittel 82 angeschlossen. An letztere ist eine externe Frischwasser-Zuleitung anschließbar. Eine Prozeßwasser-Vorlaufleitung 88 ist an die Vorlauf-Anschlußmittel 84 angeschlossen und enthält eine Pumpe 90 zur Förderung von Prozeßwasser aus dem Konditionierbehälter 8 über die Vorlauf-Anschlußmittel 84 zu einem Verbraucher, beispielsweise einer nicht dargestellten Druckmaschine, und von diesem Verbraucher oder Druckmaschine zurück zu den Rücklauf-Anschlußmitteln 86, an welche eine Rücklaufleitung 92 angeschlossen ist, durch welche das Prozeßwasser in den Konditionierbehälter 8 zurückläuft, soweit das Prozeßwasser bei dem Verbraucher bzw. bei der Druckmaschine nicht verbraucht wurde. Der Verbraucher oder die Druckmaschine ist über zwei Fluidleitungen an die Vorlauf-Anschlußmittel 84 und die Rücklauf-Anschlußmittel 86 lösbar anschließbar. Bei dem bevorzugten Anwendungsgebiet, bei welchem das Prozeßwasser das Feuchtwasser für eine Druckmaschine ist, wird das Feuchtwasser mittels der Pumpe 90 vom Geräteschrank zu einem Feuchtwasserbehälter der Druckmaschine gefördert, aus welcher ein Teil auf einen Druckplattenzylinder und/oder einen Gummizylinder oder auf andere Teile der Druckmaschine gefördert wird und ein überschüssiger Anteil des Feuchtwassers über einen Überlauf des Feuchtwasserbehälters wieder in den Geräteschrank zurückfließt. Wenn der Feuchtwasserbehälter der Druckmaschine höher angeordnet ist als der Konditionierbehälter 8, dann kann der Rückfluß des überschüssigen Feuchtwassers von dem Feuchtwasserbehälter über die Rücklauf -Anschlußmittel 86 und die Rücklaufleitung 92 in den Konditionierbehälter 8 durch Schwerkraft erfolgen. Wenn die Schwerkraft nicht ausreicht, kann eine zusätzliche Pumpe in diesen Leitungszweig eingesetzt werden. Ein solcher Prozeßwasserkreislauf oder Feuchtwasserkreislauf mit einem Überlauf-Feuchtwasserbehälter an der Druckmaschine ist ein "offener Kreislauf". Wenn der Kreislauf ein "geschlossener Kreislauf" ist, kann die Pumpe 90 in der Vorlaufleitung 88 so dimensioniert sein, daß ihr Druck auch zur Rückförderung über die Rücklaufleitung 92 ausreicht. Der Verbraucher, welcher an die Vorlauf-Anschlußmittel 84 und die Rücklauf-Anschlußmittel 86 angeschlossen ist, bildet einen externen Prozeßwasserkreislauf. Im oder am Konditionierbehälter 8 können sich Filter für die verschiedenen Flüssigkeiten befinden, welche dem Konditionierbehälter 8 zugeführt werden. Das Prozeßwasser kann Feuchtwasser oder Kühlwasser für eine Druckmaschine oder eine andere Maschine sein. Beispiele für Feuchtwasser und Kühlwasser für eine Druckmaschine sind aus der DE-Offenlegungsschrift 42 02 544 A1 und aus der EP 0 602 312 A1 bekannt. Diese beiden Schriften zeigen die bevorzugten Anwendungsgebiete für einen Geräteschrank nach der Erfindung.It is a known physical effect that heated air rises. Through the Positioning of the refrigerant condenser 16 in the top floor 43 is only inside the equipment cabinet a short cooling air path for the cooling air 54, 16 required. By positioning the refrigerant condenser 16 on the top floor 43 and the Positioning of the conditioning container 8 in the middle floor 42, you get on the bottom floor 41 a free space 76 in which heavy containers be placed directly on the cabinet floor 58 can, without the equipment cabinet to be reinforced needs and without these heavy containers in one Upper cabinet level must be lifted up. Such relatively heavy and relatively large containers for example a container 78 for the above Alcohol and a container 80 for the above Additive for preparation and conditioning of the process water in the conditioning tank 8. This Containers 78 and 80 can be storage containers or containers from which the alcohol or the additive of the metering device 60 into the conditioning container 8 be promoted. Furthermore, in this free space 76 on the bottom floor 41 fresh water connection means 82, flow connection means 84 and return connection means 86 for the process water of Conditioning container 8 are arranged. The Fresh water line 62 is via the metering device 60 connected to the fresh water connection means 82. An external fresh water supply line is connected to the latter connectable. A process water supply line 88 is connected to the flow connection means 84 and contains a pump 90 for conveying process water from the conditioning tank 8 via the flow connection means 84 to a consumer, for example a printing machine, not shown, and this Consumer or printing machine back to the return connection means 86 to which a return line 92 is connected through which the process water in the Conditioning container 8 runs back, as far as that Process water at the consumer or at the Press was not used. The consumer or the printing press is on via two fluid lines the flow connection means 84 and the return connection means 86 releasably connectable. In which preferred application, in which the Process water the fountain solution for a printing press is, the fountain solution by means of the pump 90 from Appliance cabinet to a dampening water tank Printing machine promoted, from which a part to a Printing plate cylinder and / or a blanket cylinder or is conveyed to other parts of the printing press and an excess portion of the fountain solution over one Overflow of the fountain solution tank back into the Device cabinet flows back. If the Fountain solution tank of the printing press arranged higher is as the conditioning container 8, then the Backflow of excess dampening water from that Fountain solution tank via the return connection means 86 and the return line 92 in the Conditioning container 8 done by gravity. If gravity is insufficient, an additional Pump can be used in this line branch. A such process water cycle or Fountain solution circuit with an overflow fountain container is on the press "open cycle". When the cycle is on is "closed circuit", the pump 90 in the Flow line 88 must be dimensioned so that its pressure also for return via the return line 92 is sufficient. The consumer who connects to the flow connection means 84 and the return connection means 86 is connected, forms an external Process water cycle. In or on the conditioning container 8 can filter for the different Liquids are located in the conditioning container 8 are supplied. The process water can fountain water or cooling water for a printing press or another Machine. Examples of dampening water and Cooling water for a printing press are from DE-Offenlegungsschrift 42 02 544 A1 and from EP 0 602 312 A1 known. These two writings show the preferred areas of application for a device cabinet according to the invention.
