BeschreibungDescription

Die Erfindung bezieht sich auf ein thermoelektrisches Kältesystem, das nach dem Peltiereffekt arbeitet und vorrangig in Haushalt- Hotel- und Spezialkühlgeräten eingesetzt wird.The invention relates to a thermoelectric cooling system that operates according to the Peltier effect and is primarily used in household, hotel and special cooling devices.

Thermoelektrische Kühlsysteme sind vom Prinzip her bekannt.Thermoelectric cooling systems are well known in principle.

Sie erzeugen eine relativ kleine Kälteleistung und wurden deshalb vorzugsweise in Spezidausführungen eingesetzt.They generate a relatively small cooling capacity and are therefore preferably used in special designs.

Die Vorteile dieser Systeme liegen in der geringen Geräuschentwicklung. Daraus abzuleitende Entwicklungsziele fähren dazu, diese Technik durch gezielte Weiterentwicklung so zu verbessern, daß diese Systeme auch für größere Kälteleistungen bei geringem Energieverbrauch nutzbar gemacht werden.The advantages of these systems are the low noise level. The development goals derived from this lead to improving this technology through targeted further development so that these systems can also be used for greater cooling output with low energy consumption.

Deshalb ist es Ziel und Aufgabe dieser Erfindung, die Leistungsfähigkeit der thermoelektrischen Systeme bei geringem Energieverbrauch und Beibehaltung der Geräuschlosigkeit der Arbeitsweise zu erhöhen.Therefore, the aim and object of this invention is to increase the performance of thermoelectric systems while consuming little energy and maintaining the noiselessness of their operation.

Erfindungsgemäß wird dies dadurch erreicht, daß das thermoelektrische Kältesystem mit folgendem Auftau arbeitet:According to the invention, this is achieved by the thermoelectric cooling system working with the following defrosting:

- Im Kühlraum ist zur Wärmeaufnahme ein Wärmetauscher angeordnet, und an diesem Wärmetauscher werden mindestens zwei thermoelektrische Kaskaden neben- und/oder übereinander angeordnet und mit ihm innig wärmeleitend verbunden.- A heat exchanger is arranged in the cold room to absorb heat, and at least two thermoelectric cascades are arranged next to and/or above each other on this heat exchanger and are intimately connected to it in a heat-conducting manner.

Dabei bestehen die thermoelektrischen Kaskaden mindestens aus zwei thermoelektrischen Batterien.The thermoelectric cascades consist of at least two thermoelectric batteries.

- Außerhalb des Kühlraumes ist dem Wärmetauscher im Kühlraum gegenüber, dazwischen die thermoelektrischen Kaskaden, ein zweiter Wärmetauscher angeordnet der die im Kühlraum aufgenommene Wärme an die Umgebung abgibt.- Outside the cold room, opposite the heat exchanger in the cold room, with the thermoelectric cascades between them, there is a second heat exchanger that releases the heat absorbed in the cold room to the environment.

Diese Abgabe erfolgt ohne dynamischer Unterstützung.This delivery takes place without dynamic support.

Der sich bei Betrieb des thermoelektrischen Systems einstellende Wärmefluß zwischen den beiden Wärmetauschern wird intensiviert, indem sowohl die thermoelektrischen Batterien, die im Wärmefluß auf gleicher baulicher Ebene liegen, als auch die thermoelektrischen Batterien die innerhalb einer jeden Kaskade hintereinandergeschalten sind elektrisch in Reihe miteinander verbunden werden.The heat flow between the two heat exchangers that occurs during operation of the thermoelectric system is intensified by electrically connecting in series both the thermoelectric batteries that are on the same structural level in terms of heat flow and the thermoelectric batteries that are connected in series within each cascade.

Dieser intensive Wärmefluß innerhalb der Kaskaden ist durch Wechsel der Polarität richtungsunabhängig.This intensive heat flow within the cascades is independent of direction due to the change in polarity.

Die Temperaturregelung erfolgt mittels geeigneter technischer Regelgeräte.The temperature is controlled by means of suitable technical control devices.
