Abstract

Bei einer Wärmepumpenanlage mit einem Verdichter (1), einem ersten Wärmeüberträger (2), einem zweiten Wärmeüberträger (3) und einer 4-2-Wegeventileinhelt (4) zum Umschalten zwischen einer ersten und einer zweiten Betriebsart wird die Strömungsrichtung des sich im Kältemittelkreislauf befindlichen Kältemittels derart umgeschaltet, dass der erste Wärmeüberträger (2) in der ersten Betriebsart zum Verflüssigen des Kältemittels, und in der zweiten Betriebsart zum Verdampfen des Kältemittels dient, und der zweite Wärmeüberträger (3) in der ersten Betriebsart zum Verdampfen des Kältemittels, und in einer zweiten Betriebsart zum Verflüssigen des Kältemittels dient. Die Strömungsrichtung am zweiten Wärmeüberträger (3) bleibt bei einer Umschaftung der Strömungsrichtung des Kältemittels im Wärmeübertrager unverändert, Dies ist möglich durch eine geeignete Anordnung von Rückschlagventilen, Der Wärmeüberträger, der im Heizbetrieb als Verdampfer und im Kühlbetrieb als Verflüssiger arbeitet, wird in beiden Betriebsarten sowohl von Kältemittel als auch beispielsweise von Heizungswasser in der gleichen Richtung durchströmt, so dass der Wärmeüberträger in beiden Betriebsarten als Gegenstromwärmeüberträger arbeiten kann, was eine Verbesserung der Effektivität bewirkt.
