Abstract

Die Erfindung betrifft ein System zum Kühlen von vorzugsweise flüssigen Kühl- oder Arbeitsmedien, wie sie bei Werkzeugmaschinen zum Einsatz kommen, wobei sich das Einsatzgebiet eines solchen Kühlsystems nicht nur hierauf beschränkt, sondern es können auch andere Medien, wie Luftverhältnisse in bestimmten Räumen, beispielsweise in Klimakammern, auf ein vorgegebenes Temperaturniveau gekühlt werden.The invention relates to a system for cooling preferably liquid cooling or working media, as used in machine tools, wherein the field of application of such a cooling system not only limited thereto, but it can also other media, such as air conditions in certain rooms, for example in Climatic chambers are cooled to a predetermined temperature level.

Die Aufgabe der Erfindung, ein verbessertes Kühlsystem zu schaffen, mit dem ein vorgegebenes Temperaturniveau in einem sehr kleinen Toleranzfeld gehalten werden kann, wird dadurch gelöst, daß die Verdampfereinheit, bestehend aus dem Verdampfer (1) und einer mit diesem in Verbindung stehenden Saugdruck-Sammelflasche (5), vollständig mit dem Kältemittel gefüllt ist und für den Füllstandssensor (13) für die Regelung des Füllstandes des Kältemittels in der Verdampfereinheit ein Schwinggabel-Schalter angeordnet ist, wobei für das Öffnen bzw. Schließen der Verdampfereinheit ein Saugdruckreglerventil (4) vorgesehen ist.

Figure imgaf001
The object of the invention to provide an improved cooling system with which a predetermined temperature level can be kept in a very small tolerance field, is achieved in that the evaporator unit consisting of the evaporator (1) and a related thereto suction pressure collecting bottle (5), is completely filled with the refrigerant and for the level sensor (13) for the control of the level of the refrigerant in the evaporator unit a tuning fork switch is arranged, wherein for the opening or closing of the evaporator unit, a suction pressure control valve (4) is provided ,
