Description

  

  Kälteanlage mit einem als Luftkühler ausgebildeten Verdampfer, bei welcher die  erzeugte Kälte in erster Linie durch Luft an einen Kühlraum abgegeben wird.    Die Erfindung     betrifft    eine Kälteanlage  mit einem als     Luftkühler    ausgebildeten Ver  dampfer, bei welcher die erzeugte Kälte in  erster Linie durch Luft an einen Kühlraum  abgegeben wird und der Verdampfer wenig  stens zum Teil aus doppelwandigen Rohren  besteht, deren Aussenraum mit einer     gefrier-          baren        Flüssigkeit    gefüllt ist.

   Zweck der Er  findung ist, eine Kälteanlage dieser Art zu  schaffen, welche von gedrängtem, aber ein  fachem Aufbau ist und bei welcher der Ver  dampfer bei einem Stillstande oder einer     Be-.          triebsstörung    der Kälteanlage gleichwohl die  im Kühlraum gewünschte Temperatur längere  Zeit praktisch auf derselben Höhe halten kann.  Zu diesem Behufe bilden erfindungsgemäss  doppelwandige Rohre des Verdampfers un  mittelbar mindestens einen Teil einer Tren  nungswand zwischen einem zu Kühlzwecken  zu verwendenden Teil des Kühlraumes und  einem den Verdampfer aufnehmenden Teil  dieses Raumes.    Auf der beiliegenden Zeichnung ist eine  Ausführungsform des Erfindungsgegenstandes  beispielsweise und     scheinatischveranschaulicht.     



  1 bezeichnet einen in an sich     bekannter     Weise isolierten     Kühlraum    und 2 einen Ven  tilator, der dazu bestimmt ist, einen Luft  strom in Richtung der Pfeile A durch den       Kühlraum    1     Lind    über den     Verdampfer    3 der  Kälteanlage zu treiben. Letztere weist noch  einen Verdichter 4, einen     Verflüssiger    5 und  ein     Druckminderungsventil    6 auf. Die Teile  4, 5, 6, 3 stehen über Leitungen 7, in denen  das Kältemittel in Richtung der Pfeile     B     strömt, miteinander in Verbindung.

   Die über  den Verdampfer 3 getriebene Luft erfährt  eine Abkühlung und überträgt wenigstens  einen Teil der dabei     aufgenommenen    Kälte  in den Kühlraum 1. Der Verdampfer 3 setzt  sich aus einfachen Rippenrohren 8 und dop  pelwandigen Rohren 9 zusammen. Der Aussen  raum der doppelwandigen Rohre 9 ist mit  einer gefrierbaren Flüssigkeit, beispielsweise      gefrierbarer Sole, gefüllt. Die doppelwandigen  Rohre 9 bilden nun     zusammen    mit sie ver  bindenden Stegen 10 unmittelbar eine Tren  nungswand zwischen einem zu Kühlzwecken  zu verwendenden Teil des Kühlraumes 1 der  Kälteanlage und einem den Verdampfer 3 auf  nehmenden Teil dieses Raumes 1, was eine  einfache und gedrängte Bauart ergibt.

   Die in  dem Aussenraum der doppelwandigen Rohre  9 enthaltene Sole gibt die aufgenommene  Kälte zum Teil unmittelbar an den zu<B>K</B>ühl  zwecken zu verwendenden Teil des Kühlraumes  1 ab; gleichzeitig dient sie in bekannter Weise  zum Aufspeichern von Kälte, indem sie zum  Gefrieren gebracht werden kann und so bei  kleinem Platzbedarf eine grosse Menge von  Kälte aufzuspeichern ermöglicht.  



  Wird der Verdichter 4 abgestellt, oder  tritt aus irgend einem     Grunde    in der Kühl  anlage eine Betriebsstörung ein, so dass sie  nicht weiter arbeitet, so geht die gefrorene  Sohle unter ständiger Abgabe mindestens  eines Teils der aufgespeicherten Kälte an  den     Küblraum    1 allmählich wieder in den.  flüssigen Zustand über. Mit Hilfe der doppel  wandigen Rohre 9 ist es somit -möglich, den  Kühlraum auch ausserhalb der Betriebszeit des  Verdichters 4 mit Kälte zu speisen, so dass  der Verdichter 4 längere Zeit stillgesetzt  werden kann, was um so erwünschter ist, als  ein allzu häufiges Ein- und Ausschalten der  Antriebsmaschine für diesen Verdichter in  sehr vielen Fällen tunlichst zu vermeiden ist.  Die beschriebene Bauart ermöglicht somit,  bei einem Stillstande .der Kälteanlage z. B.

      während einer normalen Betriebspause, bei  einem Stillstande oder einer Betriebsstörung,  die im Kühlraum 1 gewünschte Temperatur  längere Zeit praktisch auf derselben Höhe  zu halten.  



       Gewünschtenfalls    kann die Wand, welche  den zu Kühlzwecken zu verwendenden Teil  des Kühlraumes 1 von dem den Verdampfer  3 aufnehmenden Teil dieses Raumes trennt,  nur zum Teil aus doppelwandigen Rohren 9  und Stegen 10 bestehen, während der übrige  Teil durch einfache oder Rippenrohre 8 ge  bildet wird, öder auch noch anders ausgebildet  sein kann.     Gewünschtenfalls    kann ferner ein  Teil der in der Abbildung gezeigten Rippen  rohre 8 durch doppelwandige Rohre 9 ersetzt  werden.



  Refrigeration system with an evaporator designed as an air cooler, in which the cold generated is primarily given off by air to a cooling room. The invention relates to a refrigeration system with an evaporator designed as an air cooler, in which the cold generated is primarily delivered by air to a cooling space and the evaporator consists at least partly of double-walled tubes, the outer space of which is filled with a freezable liquid .

   The purpose of the invention is to create a refrigeration system of this type, which is compact, but a technical structure and in which the United evaporator at a standstill or loading. malfunction of the refrigeration system can keep the desired temperature in the cold room practically at the same level for a longer period of time. For this purpose, according to the invention, double-walled tubes of the evaporator form indirectly at least part of a partition wall between a part of the cooling space to be used for cooling purposes and a part of this space accommodating the evaporator. An embodiment of the subject matter of the invention is illustrated by way of example and in a schematic manner in the accompanying drawing.



  1 denotes a cold room insulated in a manner known per se and 2 a ventilator which is intended to drive an air stream in the direction of arrows A through the cold room 1 and via the evaporator 3 of the refrigeration system. The latter also has a compressor 4, a condenser 5 and a pressure reducing valve 6. The parts 4, 5, 6, 3 are connected to one another via lines 7 in which the refrigerant flows in the direction of the arrows B.

   The air driven through the evaporator 3 is cooled and transfers at least part of the cold taken up in the process to the cooling space 1. The evaporator 3 is composed of simple finned tubes 8 and double-walled tubes 9. The outer space of the double-walled tubes 9 is filled with a freezable liquid, for example freezable brine. The double-walled tubes 9 now form together with them ver binding webs 10 directly a separation wall between a part of the cold room 1 of the refrigeration system to be used for cooling purposes and a part of this room 1 receiving the evaporator 3, which results in a simple and compact design.

   The brine contained in the outer space of the double-walled tubes 9 emits some of the cold absorbed directly to the part of the cooling space 1 to be used for purposes of <B> K </B>; At the same time, it is used in a known manner to store cold, in that it can be made to freeze and thus enables a large amount of cold to be stored with a small footprint.



  If the compressor 4 is switched off, or if for any reason a malfunction occurs in the cooling system, so that it does not continue to work, the frozen sole gradually returns to the cold storage room 1, continuously releasing at least part of the stored cold. liquid state over. With the help of the double-walled tubes 9 it is thus possible to feed the cooling space with cold outside of the operating time of the compressor 4, so that the compressor 4 can be shut down for a longer period of time, which is all the more desirable as an all too frequent on and switching off the prime mover for this compressor is to be avoided as far as possible in very many cases. The type of construction described thus makes it possible, in the event of a standstill. B.

      to keep the desired temperature in the refrigerator compartment 1 practically at the same level for a longer period of time during a normal break in operation, in the event of a standstill or a malfunction.



       If desired, the wall, which separates the part of the cooling space 1 to be used for cooling purposes from the part of this space receiving the evaporator 3, only partially consists of double-walled tubes 9 and webs 10, while the remaining part is formed by simple or finned tubes 8 ge , or can also be designed differently. If desired, some of the ribbed tubes 8 shown in the figure can also be replaced by double-walled tubes 9.
