Abstract

Bei einer Kühleinrichtung, insbesondere einem Kühlschrank für ein Hotelzimmer, und einem Verfahren zur Überwachung der Kühleinrichtung, ist eine Steuereinrichtung zur Steuerung der Kühleinrichtung vorgesehen, die mit einer Überwachungseinrichtung zur Ermittlung von Störfällen versehen ist. Durch die Überwachung kann bei Störfällen der Austritt eines Kältemittels aus der Kühleinrichtung beschränkt werden. Dies ist insbesondere bei durch einen Absorptionskreislauf betriebenen Kühleinrichtungen vorteilhaft, da diese häufig mit einer geräuschlos arbeitenden Thermosyphonpumpe angetrieben werden und eine Leckage erst spät bemerkt werden kann. Vorzugsweise ist bei einem Absorptionskreislauf mit einem Austreiber (1), einem Kondensator (5), einem Verdampfer (9) und einem Absorber (12) ein Temperaturfühler (19) am Verdampfer (9) angeordnet, so daß ein Auftreten des Störfalls schnell ermittelt wird.
