Abstract

The ventilator consists of a corrugated iron heat exchanger and has a connected blower for feed air and output air, and it is ready for plugging in. The appliance is flat, and may be hung on the wall of the room to be ventilated. The heat exchanger surfaces are black anodized. The ventilator has an integral time switch. The ventilation appts. may be operated on a timer. Fuel for room heating is saved by the heat exchange process which may use counterflow, with stale air leaving the room heating fresh air entering it.

Gerät für rationelle RaumbelüftungDevice for efficient room ventilation

Die Neuheit bezieht sich auf ein steckerfertiges Gerät zur Raum belüftung mit Wärmerückführung in der Weise, daß mittels Wärme tuuscher die Wärme der Abluft an die Zuluft übertragen wird.The novelty relates to a plug-in device for room ventilation with heat recovery in such a way that the heat from the exhaust air is transferred to the supply air by means of heat wipers.

Die Verwendung von Wärmetauschern zwischen Zu- und Abluft bei der iiaumbelüftung scheint nicht bekannt zu sein. Dies dürfte einer seits darauf zurückzuführen sein, daß bis vor kurzer Zeit die Wärmeenergie relativ billig zur Verfügung stand, während andererseits die Beschaffung und der Einbau eines Wärmetauschers zur Wärmerückführung mit erheblichen Kosten verbunden ist. Bei der zunehmenden Verteuerung von OeI und Kohle wird man jedoch bei der "notwendigen" Raumbelüftung wärmesparende Maßnahmen er greifen müßen.The use of heat exchangers between supply and exhaust air for iiaum ventilation does not seem to be known. This is likely on the one hand be due to the fact that until recently the thermal energy was available relatively cheaply, while on the other hand the procurement and installation of a heat exchanger for heat recovery is associated with considerable costs. With the increasing price of oil and coal, however, heat-saving measures will be taken for the "necessary" room ventilation have to.

Die Aufgabe vorliegender Erfindung besteht nun darin, die Anwen dung von Wärmetauschern bei der Raumbelüftung so einfach und bil lig als möglich zu gestalten und dadurch einen Anreiz zur Anwen dung solcher wärmesparenden Geräte zu schaffen. Ein relativ bil liger Wärmetauscher ist der an sich bekannte Wellblech-oder Plattenwärmetauscher. Solche Wärmetauscher kommen z.B. zur Anwendung zum vorwärmen von Verbrennungsluft. (Siehe Offenlegungsschr.23o134-5) Für die Raumbelüftung muß dieser Wärmetauscher jedoch dem neuen Verwendungszweck angepaßt werden. Die Auswertung der kleinen Tem Peraturgefälle bei der Raumbelüftung erfordert einen anderen War sietauscher als zum Vorwärmen von Verbrennungsluft, wo naturgemäß sehr viel höhere Temperaturgefälle zur Verfügung stehen. Bei der neuen Formgebung des Wärmetauschers muß auch der Trend zu' stecker fertigen Geräten berücksichtigt werden.The object of the present invention is now to make the application of heat exchangers for room ventilation is so simple and cheap as possible and thereby create an incentive to use such heat-saving devices. A relatively cheap one The heat exchanger is the well-known corrugated sheet or plate heat exchanger. Such heat exchangers are used, for example, to preheat combustion air. (See Disclosure 23o134-5) For room ventilation, however, this heat exchanger must be adapted to the new purpose. The evaluation of the small temperature gradient Another heat exchanger is required for room ventilation than for preheating combustion air, where naturally much higher temperature gradients are available. In the new design of the heat exchanger, the trend towards plug-in devices must also be taken into account.

Das Gerät kann sowohl innerhalb des zu belüftenden Kaumes als auch außerhalb an der Außenmauer des Kaumes angebracht werden. In beiden Fällen sind dann nur noch zwei Mauerdurchführungen für Zu-und Abluft notwendig. Gegen Wärmeverluste kann das Gerät mit einer äuße ren Wärmeschutzschicht versehen werden.The device can be both inside the space to be ventilated and outside on the outer wall of the barely. In both cases there are only two wall ducts for supply and exhaust air necessary. The device can be provided with an outer heat protection layer to prevent heat loss.

Um das Gewicht des Gerätes niedrig zu halten, kommt als Baustoff in der Hauptsache Aluminium zur Anwendung. Versuche haben gezeigt, daß die Leistung eines solchen Gerätes bei kleinen Temperaturge fällen ganz wesentlich gesteigert werden kann, wenn die Wärmetauschflächen (Wellblech) schwarz eloxyrt sind. Aus diesem Grunde kommt das wärmetauschende Aluwellblech ausschließlich schwarz eloxyrt zur Anwendung.In order to keep the weight of the device down, the main building material used is aluminum. Tests have shown that the performance of such a device at small Temperaturge cases can be increased significantly if the heat exchange surfaces (Corrugated iron) are black anodized. For this reason, the heat-exchanging corrugated aluminum sheet is exclusively black anodized to use.

Das Belüftungsgerät wird zweckmäßig mit einer Schaltuhr, welche auf die zeitlichen Bedürfnisse eingestellt ist, ein und ausgeschaltet. The ventilation device is expediently switched on and off with a timer which is set to the time requirements.

In erster Linie soll das Gerät zur Belüftung von Saunaräumen Ver wendung finden. Aber auch zur Belüftung von Büros, Arbeitsräumen, Schulen und Krankenhäusern während der Heizperioden dürfte ein solches Gerät zunehmend wirtschaftlich interessant werden.The device is primarily intended to be used for ventilating sauna rooms Find. But also for the ventilation of offices, work rooms, schools and hospitals during the heating periods such a device will become increasingly economically interesting.

Schließlich kann das Gerät auch bei maschinell gekühlten (klimatisierten) Häumen energiesparend eingesetzt werden. In diesem Fall wird die überwarme Zuluft (Tropen) durch die kühlere Abluft gekühlt und so die Kältemaschine entlastet.Finally, the device can also be used with machine-cooled (air-conditioned) Breathing can be used in an energy-saving manner. In this case, the warm supply air (tropics) is replaced by the cooler exhaust air cooled and so relieves the refrigeration machine.
