Description

Die Erfindung betrifft einen Wärmetauscher nach dem Oberbegriff des einzigen Anspruchs.The invention relates to a heat exchanger according to the General term of the only claim.

Ein derartiger aus einem gestreckten Abschnitt und einem diesen umgebenden gewendelten Abschnitt bestehen­ der Wärmetauscher ist bereits aus der DE-OS 30 06 380 bekannt. Dieser vorbekannte Wärmetauscher ist auf der kalten Seite einer Wärmepumpe angeordnet; er ist nicht dazu geeignet, von einem Sonnenkollektor absorbierte Wärme dem Wärmespeicher zuzuführen.Such from a stretched section and consist of a coiled section surrounding this the heat exchanger is already from DE-OS 30 06 380 known. This previously known heat exchanger is on the cold side of a heat pump arranged; he is not suitable for being absorbed by a solar panel To supply heat to the heat accumulator.

Der Erfindung liegt die Aufgabe zugrunde, einen Wärme­ tauscher der eingangs genannten Art zu schaffen, bei dem die von dem Sonnenkollektor absorbierte Wärme vor­ rangig der Heizungsanlage bzw. der Wärmepumpe und erst überschüssige Wärme dem Wärmespeicher zugeführt wird.The invention has for its object a heat to create exchangers of the type mentioned at  the heat absorbed by the solar panel priority of the heating system or heat pump and first excess heat is supplied to the heat accumulator.

Erfindungsgemäß wird diese Aufgabe durch die im kenn­ zeichnenden Teil des Anspruchs angegebenen Merkmale gelöst.According to the invention, this object is achieved by the Drawing part of the claim specified features solved.

Dabei sind die Verwendung eines Koaxialwärmetauschers bestehend aus einem Mantelrohr und einem Innenrohr an sich aus der DE-OS 30 27 070 und die Vorsehung einer Wärmeisolation für den gestreckten Teil eines Wärmetau­ schers an sich aus der DE-OS 30 26 638 vorbekannt.Here are the use of a coaxial heat exchanger consisting of a jacket tube and an inner tube itself from DE-OS 30 27 070 and the Providence one Thermal insulation for the stretched part of a heat rope Schers known per se from DE-OS 30 26 638.

Die Erfindung wird im folgenden anhand einer Zeichnung erläutert.The invention is described below with reference to a drawing explained.

Der vertikal in dem Wärmespeicher angeordnete Wärmetau­ scher besteht aus einem gestreckten Abschnitt 23 und einem diesen umgebenden gewendelten Abschnitt. Beide Abschnitte bestehen aus einem Innenrohr 20, 22 und einem dieses konzentrisch umgebende, das Medium des Heizungskreislaufs oder ggf. des Speisungskreislaufs einer Wärmepumpe führenden Mantelrohr 21. Dabei durch­ strömt das von dem Sonnenkollektor kommende warme Me­ dium zunächst das Innenrohr 20 des gewendelten Ab­ schnitts von oben nach unten und steigt sodann in dem Innenrohr 22 des gestreckten Abschnitts 23 auf. Das Medium des Heizkreislaufs bzw. das Medium des Spei­ sungskreislaufs der Wärmepumpe durchströmt das Mantel­ rohr 21 des gestreckten Abschnitts 23 von oben nach unten und steigt sodann in dem gewendelten Abschnitt nach oben. The arranged in the heat accumulator Wärmetau shear consists of a stretched portion 23 and a surrounding spiral portion. Both sections consist of an inner tube 20, 22 and a jacket tube 21 concentrically surrounding this and carrying the medium of the heating circuit or possibly the supply circuit of a heat pump. The warm medium coming from the solar collector first flows through the inner tube 20 of the coiled section from top to bottom and then rises in the inner tube 22 of the elongated section 23 . The medium of the heating circuit or the medium of the feed circuit of the heat pump flows through the jacket tube 21 of the stretched section 23 from top to bottom and then rises in the coiled section upwards.

Die vorgeschlagene Anordnung ergibt eine vorteilhafte Vorrangschaltung für den Transport der Wärme aus der Solaranlage in die Heizungs- bzw. Wärmepumpenanlage:
Erst wenn das Wärmeangebot aus der Solaranlage den Bedarf der Wärmepumpen-Heizanlage übersteigt, wird Wärme in den Speicher eingeleitet. Die Wärmeisolation des gestreckten Abschnitts 23 verhindert einen Wärme­ tausch in diesem Bereich und bewirkt weiter, daß die sich in dem Wärmespeicher ausbildende erwünschte Wärme­ schichtung nicht gestört wird. Die Wärmeenergie kann daher auf einem gehobenen Temperaturniveau entnommen werden.The proposed arrangement results in an advantageous priority circuit for the transport of the heat from the solar system into the heating or heat pump system:
Only when the heat supply from the solar system exceeds the requirements of the heat pump heating system, heat is introduced into the storage. The thermal insulation of the stretched portion 23 prevents heat exchange in this area and further causes that the desired heat stratification is not disturbed in the heat accumulator. The thermal energy can therefore be extracted at an elevated temperature level.
