Abstract

The heater has a ventilator (2) to suck a room air of a room floor through a heat exchanger (3), and an outlet (10) through which the sucked room air is released perpendicularly into an area. The heater is mounted on a housing (1), which is provided on the room floor or screwed on into a wall at a ground level using a console. An integrated pump (4) and a throttle valve (5) regulate heating water volume flow to the heat exchanger.

Description

Die Erfindung bezieht sich auf einen Luftheizer oder Lufterwärmer wie er in größeren Räumen oder Hallen angewendet wird.The The invention relates to an air heater or air heater such as he in larger rooms or Halls is applied.

Durch einen solchen Luftheizer wird Raumluft umgewälzt und durch einen Wärmetauscher erwärmt, welcher von erhitztem Wasser aus einer Zentralheizung durchströmt wird.By Such an air heater is circulated room air and through a heat exchanger heated which is flowed through by heated water from a central heating.

Der erwärmte Luftstrom wird im allgemeinen zur Unterstützung der natürlichen Konvektion über ein Gebläse in den Raum eingebracht.Of the heated Airflow is generally in support of the natural Convection over a fan brought into the room.

Dieser warme Luftstrom vermischt sich nur langsam mit der kühleren Raumluft. Es kann sogar geschehen, dass die warme Luft aufgrund ihres thermischen Auftriebs nach oben aufsteigt und in die unteren Bereiche des Raumes keine Wärme aus dem Luftheizer gelangt. Anzustreben ist jedoch eine möglichst gleichmäßige Temperaturverteilung und aus energetischen Gründen eine sehr geringe Temperaturdifferenz zwischen der Luft an der Hallendecke und der am Fußboden.This Warm air flow mixes only slowly with the cooler room air. It can even happen that the warm air due to its thermal Buoy up to ascend and into the lower areas of the room no heat from the air heater. However, one should strive for as much as possible uniform temperature distribution and for energetic reasons a very small temperature difference between the air at the hall ceiling and the on the floor.

Um dies zu erreichen, werden bei herkömmlichen Luftheizern die Austrittsgeschwindigkeiten erhöht, was einen höheren Energiebedarf zur Folge hat, ohne das in jedem Falle befriedigende Temperatur- und Strömungsverhältnisse im Raum erreicht werden. Desweiteren sind herkömmliche Lufheizer dadurch gekennzeichnet, dass sie eine Trennung von Lufterwärmung durch die Heizeinheit und der erwünschten Luftumwälzung im Raum durch das Gebläse nicht zulassen. Die Folge ist, dass nur dann eine Luftumwälzung stattfindet, wenn auch gleichzeitig weiter geheizt wird, obwohl unterhalb der Decke ein mögliches Energiereservoir an warmer Luft zur Verfügung steht, welches nur mit der kühleren Luft am Fußboden vermischt werden muss.Around To achieve this, the exit speeds are in conventional air heaters elevated, what a higher Energy requirement without, in any case, satisfying Temperature and flow conditions be reached in the room. Furthermore, conventional air heaters are characterized that they have a separation of air heating by the heating unit and the desired air circulation in the room by the blower do not allow. The consequence is that only then air circulation takes place, although at the same time further heating, although below the Ceiling a possible Energy reservoir is available on warm air, which only with the cooler one Air on the floor must be mixed.

Der im Patentanspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde durch einen oder durch die Vernetzung mehrer Luftheizer miteinander eine wirkungsvolle Beheizung des Raumes zu gewährleisten und ein angenehmes Raumklima zu schaffen. Dabei sollen Energieeinsparungen durch Vermeidung von Ansammlung erwärmter Luft unter der Raumdecke erreicht werden.Of the specified in claim 1 invention, the object is based by one or by the networking of several air heaters with each other to ensure effective heating of the room and a pleasant Create room climate. This should save energy by avoiding of collection warmer Air can be achieved under the ceiling.

Die Lösung der Aufgabe wird durch die in den Patentansprüchen 1 – 6 aufgeführten Merkmale erreicht.The solution The object is achieved by the features listed in the claims 1-6.

Der mit der Erfindung erzielte Vorteil besteht darin, dass durch die senkrechte Einbringung der Luft aus dem Luftheizer die natürliche Luftzirkulation derart unterstützt und erhalten wird, dass sich innerhalb kürzester Zeit eine als angenehm empfundene Temperaturverteilung im gesamten Raum einstellt. Es entsteht eine langsame, nicht als solche spürbare, Luftumwälzung, die die Bildung von Luftschichten unterschiedlicher Temperaturen vom Boden bis zur Decke hin effektiv verhindert. Dazu werden ständig Temperatursensoren, welche an der Decke und in Personenhöhe angebracht sind, ausgewertet. Es ist hierdurch möglich, den Ventilator und die Wärmepumpe derart zu regeln, dass sich die vom Bediener am Bediengerät eingegebenen Soll-Temperatur einstellt. Dabei besteht ein weiterer Vorteil der Erfindung darin, dass Lufterhitzung und die Erzeugung der Luftzirkulation unabhängig voneinander in Funktion sein können. Die Luftzirkulation durch den Ventilator wird nur in dem notwendigen Umfang aufrechterhalten, dass das natürliche Temperaturgefälle zwischen Boden und Decke möglichst gering ist. Desweiteren wird nur dann warmes Wasser von der integrierten Wärmepumpe durch den Wärmetauscher gepumpt, wenn es die Temperaturverhältnisse im Raum erforderlich machen. Diese Entkopplung zwischen Heizen und Luftumwälzung spart zum einen Strom ein, da der Ventilator und die Pumpe für das Heizmedium durch die Regelung nicht immer mit voller Leistung arbeiten. Zum anderen wird Wärmeenergie dadurch eingespart, weil der Heizwasservolumenstrom aus der Zentralheizung durch die Regelung der Pumpe und der Drossel nur so groß ist, wie es die Solltemperatur im Raum erfordert.Of the achieved with the invention advantage is that by the vertical introduction of air from the air heater the natural air circulation so supported and that will get you in as short a time as pleasant perceived temperature distribution throughout the room. It arises a slow, not as perceptible, air circulation, the the formation of air layers of different temperatures from Floor to ceiling effectively prevented. These are constantly temperature sensors, which are attached to the ceiling and in person height, evaluated. It is thereby possible the fan and the heat pump to be regulated in such a way that the operator input on the operating unit Set temperature. There is another advantage of Invention in that air heating and the generation of air circulation independently can be in function of each other. The air circulation through the fan is only necessary in the Maintain the extent that the natural temperature gradient between Floor and ceiling as possible is low. Furthermore, only then warm water from the integrated heat pump through the heat exchanger Pumped when the temperature conditions in the room required do. This decoupling between heating and air circulation saves on the one hand a current, as the fan and the pump for the heating medium through the scheme does not always work with full power. On the other hand becomes heat energy saved because the Heizwasservolumenstrom from the central heating by regulating the pump and the throttle is only as great as it requires the set temperature in the room.

Eine weitergehende Ausgestaltung der Erfindung ist in Patentanspruch 6 gegeben. Die Weiterbildung nach Patentanspruch 6 ermöglicht es, Luftheizer nach Patentanspruch 1 – 5 als Raumheizsystem über einen Feldbus miteinander zu vernetzen. So ist es möglich in größeren oder verwinkelten Räumen (durch geschicktes Aufstellen und Kombinieren von mehren Luftheizern) die natürliche Luftzirkulation und die Wärmeeinbringung gezielt zu beeinflussen.A further embodiment of the invention is in claim 6 given. The development according to claim 6 makes it possible Air heater according to claim 1-5 as a space heating system over a Network fieldbus with each other. So it is possible in larger or winding rooms (by clever setting up and combining of several air heaters) natural Air circulation and heat input to influence specifically.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben.One embodiment The invention is illustrated in the drawing and will be described below described in more detail.

Es zeigenIt demonstrate

1 einen Luftheizer mit den wesentlichen Einzelteilen und angedeuteten Luftströmungen ohne Abdeckbleche. 1 an air heater with the essential parts and indicated air flows without cover plates.

2 einen Luftheizer mit geschlossenen Blechen. 2 an air heater with closed sheets.

Ein Luftheizer besteht beispielsweise aus einem Gehäuse (1), einem in dieses eingebauten Wärmetauscher (3) sowie einem am Gehäuse (1) angebrachten Ventilator (2) und einer Regelelektronik (7) mit Feldbus (8). Eine Pumpe (4) und ein Drosselventil (5) sind in der Zuleitung des Heizmediums des Wärmetauschers (3) eingebaut.An air heater, for example, consists of egg a housing ( 1 ), a built-in this heat exchanger ( 3 ) and one on the housing ( 1 ) mounted fan ( 2 ) and a control electronics ( 7 ) with fieldbus ( 8th ). A pump ( 4 ) and a throttle valve ( 5 ) are in the supply line of the heating medium of the heat exchanger ( 3 ) built-in.

Wie 1 zeigt, wird gemäß Pfeil (9) Raumluft durch den Ventilator (2) angesaugt und durch den Wärmetauscher (3) gesaugt. Die Luft tritt in Richtung des Pfeils (10) aus dem Luftheizer aus. Sie steigt senkrecht hoch und erzeugt eine Luftzirkulation im Raum. Dabei wird durch die Auswertung von Decken- und Raumsensoren (6) die Drehzahl des Ventilators (2) angepasst. Ist die Temperaturdifferenz zwischen Decke und Fußboden gering, so wird der Ventilator mit geringer Drehzahl betrieben oder ausgeschaltet. Diese Regelung sorgt dafür, dass Luftschichtungen mit verschiedenen Temperaturen im Raum nicht entstehen und sich ein angenehmes Raumklima mit gleichmäßiger Temperaturverteilung ausbildet.As 1 shows, as indicated by arrow ( 9 ) Room air through the fan ( 2 ) and through the heat exchanger ( 3 ) sucked. The air enters in the direction of the arrow ( 10 ) out of the air heater. It rises vertically and creates an air circulation in the room. The evaluation of ceiling and room sensors ( 6 ) the speed of the fan ( 2 ) customized. If the temperature difference between ceiling and floor is low, the fan is operated at low speed or switched off. This regulation ensures that air stratification with different temperatures in the room does not arise and forms a pleasant room climate with a uniform temperature distribution.

Durch Zuschaltung der Pumpe (4) wird die durch den Wärmetauscher (3) gesaugte Luft erwärmt. Dabei wird der Volumenstrom des Heizwassers nach Vorgabe der Soll-Temperatur eingeregelt. Ist weiteres Heizen nicht notwendig, so wird die Pumpe (4) abgeschaltet und das Drosselventil (5) geschlossen. Dadurch wird vermieden, dass sich durch Schwerkraftwirkung des Heizmediums im Leitungssystem oder durch andere Pumpen der Zentralheizung ein Volumenstrom ausbildet, der nicht erwünscht ist.By switching on the pump ( 4 ) is passed through the heat exchanger ( 3 ) heated air heated. The volume flow of the heating water is adjusted according to the setpoint temperature. If further heating is not necessary, the pump ( 4 ) and the throttle valve ( 5 ) closed. This avoids that forms a volume flow through gravity of the heating medium in the pipe system or other pumps of the central heating, which is not desirable.
