Abstract

Die Erfindung betrifft ein Verfahren zur Bereitstellung einer Wärmeleistung an einen Verbraucher für die Erwärmung eines Raumes oder Bereitung von Trinkwarmwasser mittels einer Luftwärmepumpe mit einem Luftzuführungselement, wenigstens einem Luftströmungserzeuger, einem Verdampfer und einem Wärmepumpenkreislauf, wobei die Luftwärmepumpe mit dem Luftzuführungselement verbunden ist. Dabei fördert der Luftströmungserzeuger Luft aus dem Luftzuführungselement zu dem in der Luftwärmepumpe angeordneten Verdampfer. Die von der Luftwärmepumpe bereitgestellte Wärmeleistung wird über den Wärmepumpenkreislauf zum Verbraucher geleitet. Die Luftwärmepumpe hat eine von der geförderten Luft abhängige Leistungszahl (COP = Coefficient Of Performance), die dem Quotienten aus der an den Verbraucher abgegebenen Wärmeleistung (Qc) und der zum Betrieb der Luftwärmepumpe eingesetzten Antriebsleistung (W) entspricht, wobei sich die Antriebsleistung (W) im Wesentlichen aus den elektrischen Anschlussleistungen eines Kompressors und einer Drossel der Luftwärmepumpe, des Luftströmungserzeugers sowie einer Regelungselektronik zusammensetzt. Erfindungsgemäß ist zur Erhöhung der Leistungszahl vorgesehen, dass eine Mess- und Regeleinheit zwischen wenigstens zwei unterschiedlichen Luftquellen auswählt und Luft aus der ausgewählten Luftquelle in das Luftzuführungselement einleitet oder die ausgewählte Luftquelle mit dem Luftzuführungselement verbindet.

The invention relates to a method for providing a heat output to a consumer for the heating of a room or preparation of domestic hot water by means of an air heat pump with an air supply element, at least one air flow generator, an evaporator and a heat pump circuit, wherein the air heat pump is connected to the air supply element. In this case, the air flow generator promotes air from the air supply element to the arranged in the air heat pump evaporator. The provided by the air heat pump heat output is passed through the heat pump cycle to the consumer. The air heat pump has a coefficient of performance dependent on the delivered air, which corresponds to the quotient of the heat output (Q c ) delivered to the consumer and the drive power (W) used to operate the air heat pump, whereby the drive power ( W) essentially consists of the electrical connection performance of a compressor and a throttle of the air heat pump, the air flow generator and a control electronics. According to the invention, in order to increase the coefficient of performance, a measuring and control unit selects between at least two different air sources and introduces air from the selected air source into the air supply element or connects the selected air source to the air supply element.
