Der Verbraucher 6 kann ein Zylinder oder eine Walze oder ein eine Flüssigkeit enthaltendes Teil oder eine elektronische Steuerschaltung oder dergleichen sein, innerhalb welcher die Temperatur innerhalb extrem enger Toleranzen auf einem Sollwert bzw. in einem Sollwertbereich gehalten werden soll, beispielsweise ein Temperatursollwert, welcher nicht mehr als +/- 0,25°C schwanken darf. In dem Temperierfluidkreislauf 2 wird Temperierfluid durch die Pumpe 4 in Richtung eines Pfeiles 8 zirkuliert.The temperature control device of a printing press shown in the drawing contains a temperature control fluid circuit 2, which contains a pump 4 and in which a consumer 6 of the printing press can be integrated. The consumer 6 can be a cylinder or a roller or a part containing a liquid or be an electronic control circuit or the like within which the temperature within extremely narrow tolerances on a set point or should be kept in a setpoint range, for example a Temperature setpoint, which must not fluctuate more than +/- 0.25 ° C. In The tempering fluid circuit 2 is tempering fluid through the pump 4 in Direction of an arrow 8 circulates.

Eine Temperierfluidquelle 10 ist mit Temperierfluid gefüllt und bildet eine Wärmetauscherstrecke, in welcher sich eine Wärmetauscherstrecke 12 eines Kälteerzeugers 14 befindet, durch welche Kältemittel zirkuliert. Der Kälteerzeuger 14 kann von der Art sein, wie sie von Kühlschränken und Gefriertruhen bekannt ist und durch Kompression eines gasförmigen Kältemittels in einen flüssigen Kältemittelzustand und anschließende Expansion, bei welcher das Kältemittel vom flüssigen Zustand wieder in den gasförmigen Zustand übergeht, Kälte erzeugt.A thermal fluid source 10 is filled with thermal fluid and forms one Heat exchanger section in which a heat exchanger section 12 a Refrigerator 14 is located, through which refrigerant circulates. The Refrigerator 14 may be of the type found in refrigerators and Freezers are known and compressed by a gaseous Refrigerant into a liquid refrigerant state and subsequent Expansion in which the refrigerant returns from the liquid state to the gaseous state passes, cold produces.

Eine Fluidzufuhrleitung 16 verbindet die Temperierfluidquelle 10 mit einem Einlaß 18 in den Temperierfluidkreislauf 2 an einer zwischen dem Verbraucher 6 und der Saugseite 20 der Pumpe 4 gelegenen ersten Anschlußstelle.A fluid supply line 16 connects the temperature control fluid source 10 to a Inlet 18 in the temperature control fluid circuit 2 at one between the consumer 6 and the suction side 20 of the pump 4 located first connection point.

Eine Fluidrückführleitung 22 verbindet einen Auslaß 24 des Temperierfluidkreislaufes 2 an einer zweiten Anschlußstelle zwischen der Druckseite 38 der Pumpe 4 und dem Verbraucher 6 mit einem Einlaß 26 der Temperierfluidquelle 10.A fluid return line 22 connects an outlet 24 of the Tempering fluid circuit 2 at a second connection point between the Pressure side 38 of the pump 4 and the consumer 6 with an inlet 26 of the Thermal fluid source 10.

In der Fluidrückführleitung 22 ist ein steuerbares Ventil 28, vorzugsweise in Form eines elektromagnetischen Auf-Zu-Ventils, angeordnet, welches in Abhängigkeit von dem Temperaturistwert eines Temperaturfühlers 30 offen oder zu ist.In the fluid return line 22 is a controllable valve 28, preferably in Form of an electromagnetic open-close valve, which is arranged in Dependence on the actual temperature value of a temperature sensor 30 open or is too.

Der Temperaturfühler 30 ist im Temperierflüssigkeitskreislauf 2 zwischen dem Einlaß 18 an der ersten Anschlußstelle und der Saugseite 20 der Pumpe 4 angeordnet. Er könnte auch an einer anderen Stelle des Temperierflüssigkeitskreislaufes angeordnet werden, jedoch haben Versuche gezeigt, daß an dieser in der Zeichnung dargestellten Stelle schnellere und genauere Temperaturregelungen möglich sind.The temperature sensor 30 is in the bath liquid circuit 2 between the Inlet 18 at the first connection point and the suction side 20 of the pump 4 arranged. It could also be in another place of the Bath fluid circuit can be arranged, however, have tests shown that at this point shown in the drawing faster and more precise temperature controls are possible.

Eine elektronische Steuerschaltung 34 ist funktionell mit dem Temperaturfühler 30 und dem Ventil 28 verbunden und steuert das Ventil 28 und damit seinen Fluiddurchlaß in Abhängigkeit von dem vom Temperaturfühler 30 gemessenen Temperaturistwert, um im Verbraucher einen Temperatursollwert einzuhalten, vorzugsweise mit der sehr engen Toleranz von +/- 0,25°C. An electronic control circuit 34 is functional with the temperature sensor 30 and the valve 28 connected and controls the valve 28 and thus his Fluid passage depending on that measured by the temperature sensor 30 Actual temperature value in order to maintain a temperature setpoint in the consumer preferably with the very narrow tolerance of +/- 0.25 ° C.

Der Temperierfluidkreislauf 2 ist ein geschlossener Kreislauf. Auch die Temperierfluidquelle 10 bildet zusammen mit der Fluidzufuhrleitung 16, der Fluidrückführleitung 22 und der zwischen ihnen gelegenen Strecke des Temperierfluidkreislaufes 2, welche die Pumpe 4 enthält, einen geschlossenen Kreislauf.The temperature control fluid circuit 2 is a closed circuit.

Der Temperaturfluidkreislauf 2 ist auf seinem zwischen der Druckseite 38 der Pumpe 4 und dem Verbraucher 6 gelegenen Abschnitt mit einer Heizung 40 versehen. Die zweite Anschlußstelle mit dem Auslaß 24 liegt zwischen der Druckseite 38 der Pumpe 4 und der Heizung 40. Die Heizung 40 ist in Abhängigkeit von dem Temperaturistwert des Temperaturfühlers 30 und dem Temperatursollwert des Verbrauchers 6 von der Steuerschaltung 34 aktivierbar. Dadurch kann der Verbraucher 6 in der Anlaufphase der Druckmaschine, wenn seine Temperatur noch unterhalb seiner optimalen Betriebstemperatur liegt, d.h. unterhalb seiner Temperatursollwertes, von dem Temperierfluid des Temperierfluidkreislaufes 2 erwärmt werden. Bevor dann der Verbraucher 6 seinen Temperatursollwert erreicht, oder spätestens wenn er ihn erreicht, wird die Heizung 40 abgeschaltet. Bei Überschreiten des Temperatursollwertes wird anstelle der Heizung 40 das Ventil 28 aktiviert, um dem Temperierfluidkreis 2 über den Einlaß 18 gekühltes Temperierfluid aus der Temperierfluidquelle 10 zuzuführen. Bei dieser Zufuhr wird, weil es sich um ein geschlossenes System handelt, gleichzeitig über das Ventil 28 eine entsprechende Menge Temperierfluid aus dem Temperierfluidkreislauf 2 zur Temperierfluidquelle 10 abgeführt. Das Temperierfluid ist vorzugsweise Wasser.The temperature fluid circuit 2 is on its between the pressure side 38 of the Pump 4 and the consumer 6 section with a heater 40 Mistake. The second connection point with the outlet 24 lies between the Pressure side 38 of the pump 4 and the heater 40. The heater 40 is in Dependence on the actual temperature value of the temperature sensor 30 and the Temperature setpoint of the consumer 6 from the control circuit 34 enableable. This allows the consumer 6 in the start-up phase Printing press when its temperature is still below its optimal Operating temperature, i.e. below its temperature set point from which Tempering fluid of the Temperierfluidkreislauf 2 are heated. Before then the consumer 6 reaches its temperature setpoint, or at the latest when it reached it, the heater 40 is turned off. If the Temperature setpoint, the valve 28 is activated instead of the heater 40 the tempering fluid circuit 2 via the inlet 18 cooled tempering fluid from the Supply tempering fluid source 10. This feed is because it is a closed system acts, at the same time via the valve 28 corresponding amount of tempering fluid from the tempering fluid circuit 2 Tempering fluid source 10 removed. The temperature control fluid is preferred Water.

Wie die Zeichnung zeigt, können an die Temperierfluidquelle 10 mehrere Fluidzufuhrleitungen 16 und Fluidrückführleitungen 22 parallel angeschlossen werden für weitere anders oder vorzugsweise gleich ausgebildete Temperiervorrichtungen. In der Zeichnung ist auf diese Weise ein weiterer Temperierfluidkreislauf 2 über eine Fluidzufuhrleitung 16-2 und eine Fluidrückführleitung 22-2 angeschlossen. Gleiche Teile sind jeweils mit gleichen Bezugszahlen versehen und werden nicht nochmals beschrieben.As the drawing shows, several can be connected to the temperature fluid source 10 Fluid supply lines 16 and fluid return lines 22 connected in parallel are trained differently or preferably the same for others Tempering. Another is in the drawing in this way Tempering fluid circuit 2 via a fluid supply line 16-2 and Fluid return line 22-2 connected. The same parts are always the same Reference numbers are provided and will not be described again.
