Abstract

The solar heating device has a solar heating body storage collector incorporated in a wall construction used as the heat source and coupled via one or more heat pipes with an opposing room heating surface e.g. with part of the surface of the heat pipes in direct contact with the room air. The condensed heat transfer medium at the condenser region of the heat pipes flows back to the evaporator region of the heat pipes at the storage collector using a height difference, or capillaries incorporated in the heat pipes.

Description

Heizungssysteme im Naturumlauf sind schon seit längerem bekannt. So zeigen die Patentschriften FR 2 537 256, US 4 183 350 Heizvorrichtungen mit Naturumlaufsystem, die in vertikaler Verbindung mit der Wand stehen. Heizvorrichtungen mit Speicherkollektoren sind ebenfalls bereits Stand der Technik. Die Offenlegungsschrift DE 42 39 286 A1 zeigt einen Speicherkollektor zur freien Aufstellung im Gelände. Die DE 198 50 289 A1 zeigt erstmalig ein Heizungssystem, das einen Speicherkollektor als Wärmequelle nutzt, der im Wandaufbau integriert ist und die Wärme über Rohrleitungen im Naturumlauf an einen über dem Speicherkollektor an der Gebäudeinnenwand angeordneten Heizkörper abgeben kann. Der Vorteil dieses Systems ist das verlustarme Ansammeln von Wärmeenergie auf gegenüber einer Heizfläche niedrigerem geodätischen Höhenniveau. So kann sichergestellt werden, daß zum Zeitpunkt des Bedarfes Wärme im Naturumlauf zur Verbrauchsstelle transportiert werden kann. Der Nachteil dieses Systems ist sowohl die Notwendigkeit einer bestimmten Mindesttemperaturdifferenz zwischen Speicherkollektor und Heizfläche als auch eine minimale Höhendifferenz für die Anordnung beider Einheiten übereinander.Heating systems in natural circulation have been known for a long time. So they show Patents FR 2 537 256, US 4 183 350 natural circulation heating devices, the be in vertical connection with the wall. Heaters with storage collectors are also state of the art. The published patent application DE 42 39 286 A1 shows a storage collector for free installation in the field. DE 198 50 289 A1 shows for the first time a heating system that uses a storage collector as a heat source, which in the Wall structure is integrated and the heat via pipes in natural circulation to one over the storage collector on the inside wall of the radiator. The advantage of this system is the low-loss accumulation of thermal energy compared to a heating surface at a lower geodetic height level. This can ensure be that at the time of need heat in natural circulation to the point of consumption can be transported. The disadvantage of this system is both the need for one certain minimum temperature difference between the storage collector and heating surface as well a minimal height difference for the arrangement of both units on top of each other.

Der Erfindung liegt die Aufgabe zugrunde, eine Heizvorrichtung mit einem Speicherkollektor im Naturumlaufsystem zu schaffen, die einen besseren Wärmeübergang vom Speicher­ kollektor zum Heizkörper gewährleistet.The invention has for its object a heater with a storage collector in the natural circulation system to create a better heat transfer from the storage collector to the radiator guaranteed.

Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.

Bei einem Naturumlaufheizungssystem mit Speicherkollektor, im folgenden Solarheizkörper genannt, wird die höher liegende Heizfläche nicht nur hydraulisch mit dem darunterliegenden Speicherkollektor verbunden, sondern zusätzlich über hydraulisch entkoppelte Heat Pipes (Wärmerohre). Diese Heat Pipes sind so angeordnet, daß sowohl für den Speicherkollektor als auch für die Heizfläche eine wärmeschlüssige Verbindung hergestellt wird. Es besteht ein Gefälle in diesen Heat Pipes, das sicherstellt, daß nach der Kondensation des Arbeitsmittels in den Kondensatoren der Heat Pipes, die sich in bzw. an der höher liegenden Heizfläche befinden, dieses abwärts in die Verdampfer der Heat Pipes, die sich im bzw. am Speicherkollektor befinden, fließt. Die Arbeitsmittelauswahl und dessen Verdampfungs­ temperatur können je nach Anwendungsfall variiert werden. Bei einer Auswahl von einem Arbeitsmittel mit z. B. 30°C Verdampfungstemperatur bei einem voreingestellten Druck wird folglich Wärme schon bei diesem Temperaturniveau zur Raumheizfläche transportiert. Der Solaranteil und der Jahresnutzungsgrad des Solarheizkörpers werden damit vergrößert.In a natural circulation heating system with a storage collector, in the following solar heating element called, the higher lying heating surface is not only hydraulic with the one below Storage collector connected, but also via hydraulically decoupled heat pipes (Heat pipes). These heat pipes are arranged so that both for the storage collector as well as a heat-tight connection for the heating surface. There is one Slope in these heat pipes, which ensures that after the condensation of the working fluid in the condensers of the heat pipes, which are located in or on the higher heating surface are, this down into the evaporator of the heat pipes, which are in or on Storage collector are flowing. The choice of work equipment and its evaporation temperature can be varied depending on the application. With a choice of one Work equipment with z. B. 30 ° C evaporation temperature at a preset pressure consequently heat is transported to the room heating surface at this temperature level. The This increases the solar share and the annual utilization of the solar heating element.
