Abstract

The aerating and ventilating device is constructed in such a way that an air-to-air heat exchanger (4), a reversible fan (3) and a hood (1) for opening are fitted in a housing (2). The device functions in such a way that with inside cooling and outside temperatures which are fundamentally higher than the inside temperature the fresh air drawn in is precooled. If the outside temperature is significantly lower than the inside temperature then the fresh air is preheated. With moderate outside temperatures within the range of about 18 to 22 deg.C the fresh air is drawn in directly through the open hood.

Be- und Entlüftungsgerät mit Kälte- bzw. WärmerückgewinnungVentilation unit with cold or heat recovery

Beschreibung.
1. Allgemein.Description.
1 General.

Be- und Entlüftungsgeräte mit Wärmerückgewinnung sind für die Anwendung in größeren Räumen oder als Zentralanlagen bekannt. Geräte für kleinere Räume, z. B. Fahrzeuge, Boote, Wohncontainer u. a., wurden bisher nicht verwirklicht. Das hier beschriebene Gerät übernimmt die Be- und Entlüftung kleinerer, bewohnter Räume. Dabei wird gleichzeitig die in der Abluft enthaltene „Kälte" bzw. Wärme z. T. zurückgewonnen.Ventilation and exhaust devices with heat recovery are known for use in larger rooms or as central systems. Devices for smaller rooms, e.g. vehicles, boats, residential containers, etc., have not yet been implemented. The device described here takes care of the ventilation and exhaust of smaller, occupied rooms. At the same time, the "cold" or heat contained in the exhaust air is partially recovered.

1. Konstruktiver Aufbau und Funktion1. Structural design and function

Das hier vorgestellte Gerät wird auf dem Dach des zu be- und entlüftenden Raumes montiert. Es besteht aus einem Gehäuse (2) mit einer zu öffnenden Haube (1). In das Gehäuse (2) ist in die untere Dachaussparung ein Ventilator (3) eingebaut. In dem Gehäuse (2) befindet sich weiterhin ein Kreuzstromwärmetauscher Luft / Luft. Unter dem Wärmetauscher sind Öffnungen angebracht. Je nach Außentemperatur ta sind 3 Betriebszustände möglich.The device presented here is mounted on the roof of the room to be ventilated. It consists of a housing (2) with an opening hood (1). A fan (3) is installed in the lower roof recess of the housing (2). The housing (2) also contains a cross-flow air/air heat exchanger. Openings are provided under the heat exchanger. Depending on the outside temperature ta, 3 operating states are possible.

A. Die Außentemperatur ta ist sehr viel wärmer als die Innentemperatur ti: Es wird ein Kühlgerät eingesetzt, das die Innenluft im Umwälzverfahren kühlt. Zur Belüftung wird der Ventilator so gesteuert, dass er Frischluft in den Raum bläst. Die Abluft entweicht aufgrund des geringen Raumüberdruckes und aufgrund des thermischen Einflusses durch den Wärmetauscher (4) ins Freie. Dabei wird die vom Ventilator angesaugte warme bzw. heiße Frischluft durch Wärmetausch vorgekühlt.A. The outside temperature ta is much warmer than the inside temperature ti: A cooling device is used that cools the inside air using a circulation process. For ventilation, the fan is controlled so that it blows fresh air into the room. The exhaust air escapes to the outside due to the low room pressure and the thermal influence through the heat exchanger (4). The warm or hot fresh air sucked in by the fan is pre-cooled by heat exchange.

B. Die Außenluft ist sehr viel kälter als die Innenluft (Winter). Der Innenraum wird beheizt. Zur Belüftung wird der Ventilator (3) umgepolt, so dass er die Raumluft absaugt und durch den Wärmetauscher (4) ins Feie bläst. Die Frischluft wird über den Wärmetauscher angesaugt. In dem Wärmetauscher (4) findet ein Wärmetausch zwischen der Abluft und der Zuluft statt. Die Zuluft wird vorgewärmt.B. The outside air is much colder than the inside air (winter). The interior is heated. For ventilation, the fan (3) is reversed so that it sucks the room air out and blows it outside through the heat exchanger (4). The fresh air is sucked in via the heat exchanger. In the heat exchanger (4) a heat exchange takes place between the exhaust air and the supply air. The supply air is preheated.

. C. Die Außen- und die Innentemperatur sind ungefähr gleich: In diesem Fall wird die Haube geöffnet. Der Ventilator (3) bläst die Frischluft direkt in den Innenraum. Der Wärmetauscher ist kurzgeschlossen. C. The outside and inside temperatures are approximately the same: In this case, the hood is opened. The fan (3) blows the fresh air directly into the interior. The heat exchanger is short-circuited

Der Vorteil der Kälte- bzw. Wärmerückgewinnung besteht darin, dass, speziell bei gut isolierten und dicht abschließbaren Räumen, eine geringere Kühl- bzw. Heizleistung bei gleichzeitiger Frischbelüftung erforderlich ist. Eine ausreichende Frischluftversorgung ist in bewohnten, kleineren Räumen, z.B. Wohnwagen oder Wohnmobilen, aus gesundheitlichen Gründen besonders wichtig. Eine Kälte- bzw. Wärmerückgewinnung spart Energie, die für die Kühlung oder Heizung notwendig ist.The advantage of cold or heat recovery is that, especially in well-insulated and tightly sealed rooms, less cooling or heating power is required while still providing fresh ventilation. A sufficient supply of fresh air is particularly important for health reasons in inhabited, smaller rooms, e.g. caravans or mobile homes. Cold or heat recovery saves energy that is needed for cooling or heating.
