Abstract
Die vorliegende Erfindung bezieht sich auf eine Kälteanlage mit folgenden zu einem Kreisprozess für ein Kältemittel verbundenen Komponenten: einem Verdampfer (2), einem diesem in Strömungsrichtung des gasförmigen Kältemittels nachgeordneten inneren Wärmeaustauscher (3), einem Verdichter (4), einem Verflüssiger (5), welchem in Strömungsrichtung des nunmehr flüssigen Kältemittels der innere Wärmeaustauscher (3) nachgeschaltet ist, und einem dem inneren Wärmeaustauscher (3) in Strömungsrichtung des flüssigen Kältemittels nachgeordneten und dem Verdampfer (2) vorgeschalteten Expansionsventil (6), welches einen Überhitzungsfühler (11) aufweist. Die Erfindung ist dadurch gekennzeichnet dass das Expansionsventil (6) ein solches mit einer statischen Überhitzung ≤ 2 K ist und der Überhitzungsfühler (11) in Strömungsrichtung des Kältemittels hinter dem Verdampfer (2) und vor dem inneren Wärmeaustauscher (3) angeordnet ist. The present invention relates to a refrigeration system with the following components connected to a cycle for a refrigerant: an evaporator (2), an internal heat exchanger (3) downstream of it in the flow direction of the gaseous refrigerant, a compressor (4), a condenser (5) , which downstream of the inner heat exchanger (3) in the flow direction of the now liquid refrigerant, and an expansion valve (6) upstream of the inner heat exchanger (3) in the flow direction of the liquid refrigerant and upstream of the evaporator (2), which has an overheating sensor (11) , The invention is characterized in that the expansion valve (6) is one with a static superheat ≤ 2 K and the superheat sensor (11) in the flow direction of the refrigerant behind the evaporator (2) and in front of the inner heat exchanger (3) is arranged.
