Description

Es ist üblich, die Kältemittelverdampfer in Kühlräumen mit Tau- bzw. Tropfwasserauffangvorrichtungen auszustatten, die vielfach gleichzeitig die Aufgabe von Luftleitvorrichtungen übernehmen.It is common practice to install the refrigerant evaporator in cold stores with a condensation or Equip drip water collecting devices, which often do the same job take over from air guiding devices.

Das an diesen Tau- bzw. Tropfwasserauffangvorrichtungen ablaufende Wasser wird meist in einer Sammelrinne aufgefangen und aus dem Kühlraum hinausgeleitet.The drainage on these condensation or drip water collecting devices Water is usually collected in a collecting channel and directed out of the cold room.

Die den Kältemittelverdampfer durchströmende Luft wird nach dem Verlassen des Verdampfers an denTau- bzw. Tropfwasserauffangvorrichtungen entlang geleitet. Liegt die Temperatur dieser Luft unterhalb des Gefrierpunktes, so kann es vorkommen, daß das- in der Tauwassersammelrinne befindliche Wasser zu Eis gefriert. Bei genügend langen Ausschaltperioden der Kältemaschine taut das in der Tauwassersammelrinne gefrorene Wasser wieder auf und fließt ab. Sind jedoch die Betriebszeiten der Kältemaschine lang und die Standperioden kurz, so kommt dieses Eis nicht immer zum Auftauen, so daß es wächst und mit der Zeit die Rinne ausfüllt. Dieser Zustand kann zu erheblichen Störungen und auch zu Beeinträchtigungen der Kaltlagergüter führen.The air flowing through the refrigerant evaporator is after leaving of the evaporator passed along the thawing or drip water collecting devices. If the temperature of this air is below freezing point, it can happen that the water in the condensate collecting channel freezes to ice. With enough long switch-off periods for the refrigeration machine, this thaws in the condensate collecting channel frozen water comes back up and drains away. However, are the operating times of the chiller long and the standing periods short, this ice does not always thaw, like that that it grows and over time fills the gully. This condition can become significant Malfunctions and also to impairment of the cold stored goods.

Es sind bereits Anordnungen vorgeschlagen worden, bei denen das Auftauen des in der Tauwassersammelrinne sich bildenden Eises mittels eines Heizgases oder einer Sole durchgeführt wird, derart, daß diese durch unter oder in der Tauwassersammelrinne vorgesehene Kanäle hindurchgeleitet werden. Ein in dieser Weise durchgeführtes Auftauen beschränkt sich aber nur auf -die einzelnen Abtauperioden, und es ist ein Nachteil dieser Vorrichtungen, daß sich während des Betriebes der Kältemaschine in der Tauwassersammelrinne immer wieder erneut Eis bildet.Arrangements have already been proposed in which the thawing of the ice forming in the condensate collecting channel by means of a heating gas or a brine is carried out in such a way that it passes through under or in the condensate collecting channel provided channels are passed through. Thawing carried out in this way limited to the individual defrosting periods, and it is a disadvantage these devices that are in the condensate gutter during operation of the refrigeration machine ice forms again and again.

Die vorliegende Erfindung behebt die geschilderten Nachteile.The present invention overcomes the disadvantages outlined.

Um das Gefrieren von Wasser in der Tauwassersammelrinne zu vermeiden, wurde erfindungsgemäß die zum Verdampfer führende Kältemittelflüssigkeitsleitung dergestalt innerhalb oder unterhalb der Tauwassersammelrinne verlegt, daß das diese Leitung durchströmende flüssige Kältemittel seine Wärme an das etwa in der Tauwassersammelrinne befindliche Eis abgibt und dieses dadurch zum Auftauen bringt.To prevent water from freezing in the condensate collecting channel, became the refrigerant liquid line leading to the evaporator according to the invention laid in such a way within or below the condensate gutter that this The heat of the liquid refrigerant flowing through the pipe is transferred to the condensate collecting channel, for example releases the ice and thaws it.

In den Abbildungen sind Ausführungsbeispiele der Erfindung dargestellt. Abb. i zeigt eine mit Tauwasser bzw. Eis gefüllte Sammelrinne i mit einer darin angeordneten Kältemittelflüssigkeitsleitung 2. Die in Abb. 2 dargestellte Tauwassersammelrinne ist mit einer muldenförmigen Ausbuchtung 3 versehen, in welcher sich die Kältemittelflüssigkeitsleitung 4 befindet. Bei der Ausführungsform entsprechend Abb. 3 ist die Kältemittelflüssigkeitsleitung 5 unterhalb der Tauwassersammelrinne verlegt.Exemplary embodiments of the invention are shown in the figures. Fig. I shows a collecting channel i filled with condensation water or ice with one inside arranged refrigerant liquid line 2. The condensation water collecting channel shown in Fig. 2 is provided with a trough-shaped bulge 3 in which the refrigerant liquid line is located 4 is located. In the embodiment according to Fig. 3, the refrigerant liquid line is 5 laid below the condensate collecting channel.
