Querstramlüfter für Freikühlverdampfer Stand der TechnikCross-flow fan for free-cooling evaporator State of the art
Freikühltheken uerden für alle Lebensmittelbereiche eingesetzt. Die Auslageflächen uerden durch Lamellenverdampfer mit oder ahne Umluft gekühlt.Free-cooling counters are used for all food areas. The display areas are cooled by finned evaporators with or without circulating air.
1. Bei der stillen Kühlung ist ein Lamellenverdampfer an der Rückseite der Auslagefläche angeordnet, die im Uerdampfer erzeugte Halte wird durch Eigenkonvektion über die Ausstellfläche bewegt.1. With silent cooling, a finned evaporator is arranged on the back of the display area, the air generated in the evaporator is moved over the display area by natural convection.
2. Bei der Umluftkühlung uird die kalte Luft vom Uerdampfer durch Uentilatoren über die Ausstellfläche geblasen. Hierbei sind die Uerdampfer unter der Ausstellfläche angeordnet. Die Uentilatoren sindin Abständen vor oder über den Uerdampfern angebracht. Die Luftverteilung ist durch das punktförmige Einblasen der Uentilatoren nicht optimal gelöst. Es gibt Zonen im Uerdampfer die nur schach von der Luft umspült werden. Die Folge ist ein starkes Bereifen von Uerdampferzonen bis zur totalen Uereisung. Eine bessere Luftverteilung am Uerdampfer erreicht man mit Querstromgebläsen wie sie aus der Klimatechnik(Nachtstromspeicher) bekannt sind. Hierbei sind die Gebläse auf bestimmte Längen festgelegt.2. With recirculation cooling, the cold air from the evaporator is blown over the display area by fans. The evaporators are arranged under the display area. The fans are installed at intervals in front of or above the evaporators. The air distribution is not optimally solved by the point-like blowing of the fans. There are zones in the evaporator that are only slightly washed over by the air. The result is heavy frosting of evaporator zones, leading to total icing. Better air distribution on the evaporator can be achieved with cross-flow fans as known from air conditioning technology (night storage). The fans are set to certain lengths.
Hier setzt die Erfindung ein.
Ausführung AThis is where the invention comes in.
execution A
Der Uerdampfer ist an der Rückseite der Ausstellfläche senkrecht angeordnet Fig.1 Über dem Uerdampfer ist ein Querstromgebläse installiert Fig.2 1, 2, 3.The evaporator is arranged vertically on the back of the display area Fig.1 A cross-flow fan is installed above the evaporator Fig.2 1, 2, 3.
Die Lüfterualze besteht aus einem straggepreßten Aluminiumprofil dessen Querschnitt ein Rohr mit aufgesetzten Längslamellen darstellt Fig.2,2. Die Lamellen können senkrecht zur Rohrmitte, oder in Durchmesserachse geneigt angewinkelt, oder gebogen sein. Fig.5, 2, 3, k. The fan blade consists of an extruded aluminum profile whose cross-section represents a tube with attached longitudinal fins (Fig. 2, 2). The fins can be perpendicular to the center of the tube, or inclined in the diameter axis, angled, or bent (Fig. 5, 2, 3, k).
Die Lagerung der Lüfterujalze wird durch eingepresste Kunststoffschalen Fig. it, 1 mit eingesetzten Kugellagern erreicht. Diese Lager werden an Winkeln montiert, die an der Rückwand oder der Decke des Uerdampferraumes befestigt sind. Fig. k. Die Lüfterwalze aus dem Alu-Profil Fig. 2, 2 ist daher in jeder beliebigen Länge herzustellen.The fan roller is supported by pressed-in plastic shells Fig. 11 with inserted ball bearings. These bearings are mounted on brackets which are attached to the rear wall or ceiling of the evaporator room. Fig. k. The fan roller made of the aluminum profile Fig. 2, 2 can therefore be manufactured in any length.

Am Befestigungsuinkel Fig. U,3 ist das Luftführungsprofil Fig. 2, 3 befestigt. Dieses Luftführungsprofil besteht aus einem U-förmigen Alu- oder Kunststoffprofil mit ausgeschäumtem Polyurethan-Teil, dessen Rückseite kreisförmig ausgebildet ist, und dem Radius der Lüfterualze angepasst ist.The air duct profile Fig. 2, 3 is attached to the fastening angle Fig. U , 3. This air duct profile consists of a U-shaped aluminum or plastic profile with a foamed polyurethane part, the back of which is circular and adapted to the radius of the fan blade.
Das Profil steht mit der Unterkante auf den Verdampferlamellen
auf. Fig.2, 5, und ist mit der verlängerten Vorderseite Fig.2,6
am Verdampfer befestigt. Hierdurch ist ein Verschieben des Profils nach unten oder nach hinten zur Lüfterualze unmöglich.
Als Antrieblist ein Außenläufermotor won Vorteil. Die Welle
des Motors uird in das Kunststofflager eingesteckt und mit
einer Schraube gesichert. Die Befestigungsplatte vom Motor Fig.it, 5 ist am Winkel Fig.4, 3 angeschraubt. Das Gegenlager
ist identisch mit dem Antriebslager.
Ausführung BThe profile rests with its lower edge on the evaporator fins (Fig.2, 5) and is attached to the evaporator with the extended front (Fig.2, 6). This makes it impossible for the profile to be moved downwards or backwards towards the fan blade. An external rotor motor is advantageous as a drive. The shaft of the motor is inserted into the plastic bearing and secured with a screw. The mounting plate of the motor (Fig.1, 5) is screwed to the angle (Fig.4, 3). The counter bearing is identical to the drive bearing.
Version B
Verdampferanordnung unterhalb der Ausstellfläche Fig.3 Hierbei ist der Verdampfer Fig. 3, 1 liegend angeordnet. Lüfterualze und Luftführungsprofil sind am Verdampfer befestigt uie Ausführung A. Fig.3, 2Evaporator arrangement below the display surface Fig.3 The evaporator Fig. 3, 1 is arranged horizontally. The fan coil and air guide profile are attached to the evaporator as version A. Fig.3, 2
Fig.5 zeigt eine Kombination von 3 Verdampfern Fig.5, 1 mit Querstromlüftern Fig. 5, 2,3,^ für größere Kühlleistungen. Hierbei sind die über den Querstromlüftern angebrachten Luftleitbleche erforderlich.Fig.5 shows a combination of 3 evaporators Fig.5, 1 with cross-flow fans Fig. 5, 2,3,^ for greater cooling performance. The air baffles mounted above the cross-flow fans are required here.
Dieses Querstrom-Luftsystem ist für alle Klimageräte anuendbar, uie z.B. Nachtstromspeichergeräte, Klimatruhen, Luftschleieranlagen, Kühlraumverdampfer, Konvektorheizkörper etc. Durch unterschiedliche Durchmesser der Lüfterualze und Höhe und Anzahl der aufgesetzten Längslamellen sind variable Luftmengen zu erreichen. Die Luftgeschuindigkeit kann durch Drehzahländerung des Antriebsmotors bestimmt uerden.This cross-flow air system can be used for all air conditioning units, such as night storage units, air conditioning units, air curtain systems, cold room evaporators, convector radiators, etc. Variable air volumes can be achieved by using different diameters of the fan blades and the height and number of the attached longitudinal slats. The air speed can be determined by changing the speed of the drive motor.
