This has an efficient effect, which leads away through an exhaust air opening (12), with a highly effective heat exchange at the condenser 11.

Ferner sind im Fach 20 noch ein Trockner 32, die Kapillare 33 und der Tauwasserverdunster 34 untergebracht. written cooling device removable. Here, the cabinet 1 is indicated by the dash-dotted lines which essentially delimit the upper cooling compartment 4 with the upper evaporator 14, the lower cooling compartment 6 with the lower evaporator 16 and the chimney-like compartment 20 for the cooling unit with the condenser 31 and the compressor 30 . Furthermore, a dryer 32, the capillary 33 and the condensate evaporator 34 are accommodated in the compartment 20.

Für die Kühlung folgt das umlaufende Kühlmittel dem Rohrsystem nacheinander vom Kompressor 30 über den Tauwasserverdunster 34, eine Rahmenheizung 35, den Kälteerzeuger 31, die Drossel-Kapillare 33, den unteren For cooling, the circulating coolant follows the pipe system in succession from the compressor 30 via the condensate evaporator 34, a frame heater 35, the cooling generator 31, the throttle capillary 33, the lower one

Das üblicherweise mit Heissgas durchführbare Abtauen erfolgt dann durch eine Shuntleitung 37, welche über ein Ma-5 gnetventil 36 einschaltbar ist. Die Shuntleitung 37 ist zwischen Kompressor 30 und unterem Verdampfer 16 eingeschaltet und gestattet eine Überbrückung des Kälteerzeugers. Defrosting, which can usually be carried out with hot gas, then takes place through a shunt line 37, which can be switched on via a magnetic valve 36. The shunt line 37 is connected between the compressor 30 and the lower evaporator 16 and allows the refrigeration generator to be bridged.

Aus dem Vorbeschriebenen ergibt sich somit eine Kühl-io einrichtung in Form eines Grossraumschrankes von gefalliger, kompakter Form mit einer hochwirksamen Kühlluftströmung und optimaler Zugänglichkeit für Service-Arbeiten. From the above, this results in a cooling io device in the form of a large room cabinet of pleasant, compact shape with a highly effective cooling air flow and optimal accessibility for service work.
