Abstract

Es wird ein Wärmetauscher (3) zwischen einem Kältemittel einer Wärmepumpe (2) und Brauchwasser mit einem schraubenförmig gebogenen Leitungsrohr (5) für das Kältemittel beschrieben. Um ein Austreten von Leckage des Kältemittels in das Brauchwasser zu unterbinden, wird vorgeschlagen, daß das Leitungsrohr (5) für das Kältemittel mit Spiel in ein Schutzrohr (6) eingesetzt und mit dem Schutzrohr (6) unter einer gegenseitigen Anlage in einem bezüglich der Rohrachse gegenüberliegenden Umfangsbereich quer zur Schraubungsachse (7) abgeflacht ist.

Figure imgaf001
A heat exchanger (3) between a refrigerant of a heat pump (2) and service water with a helically bent conduit (5) for the refrigerant is described. In order to prevent leakage of the refrigerant into the service water, it is proposed that the conduit (5) for the refrigerant with play in a protective tube (6) used and with the protective tube (6) under mutual contact in a respect to the tube axis opposite peripheral region is flattened transversely to the screw axis (7).
