Abstract

Der 3-Zonen-Wärmetauscher ist ein Spezial-Wärmetauscher für Luft-Wasser-Wärmepumpen um erneuerbare Energien effizient zu erwirtschaften.The 3-zone heat exchanger is a special heat exchanger for air-water heat pumps to efficiently generate renewable energy.

Description

Wasserwärmetauscher üblicher Bauweise haben meist 2 oder mehrere Wärmetauscherkammern, die so miteinander verbunden sind, dass eine optimale Wärmeübertragung mit allen Medien zustande kommt!Water heat exchanger usual Construction usually have two or more heat exchanger chambers, the like connected to each other, that optimum heat transfer with all media comes about!

Bei Luft-/Wasserwärmepumpen werden handelsübliche Wasserwärmetauscher mit 2 Wärmetauscherkammern mit gegenseitiger optimalen Wärmeübertragung eingesetzt, um erneuerbare Energien (Energiegewinn bis zu 75% aus Außenluft) für die Brauch- und/oder Trinkwassererwärmung in Ein- oder Mehrfamilienhäusern, für Büro oder Werkstatt, gewerblich oder privat, effizient zu gewinnen.at Air / water heat pumps become commercial Water heat exchanger with 2 heat exchanger chambers with mutual optimal heat transfer used to renewable energy (energy gain up to 75% off Outside air) for the custom and / or drinking water heating in single or multi-family houses, for office or Workshop, commercial or private, efficient to win.

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, dass Luftwärmepumpen bei niedrigen Außenlufttemperaturen, ab +5°C und tiefer, wegen der Luftfeuchtigkeit nach einer bestimmten Laufzeit Abtauphasen einlegen müssen.Of the in claim 1 protection invention is based on the problem that air heat pumps at low outside air temperatures, from + 5 ° C and deeper, because of the humidity after a certain period To insert defrosting phases.

Zur Abtauphase wird der Kühlmittelkreis umgekehrt, wobei jetzt das warme Kältemittel im Kreislauf den Luftwärmetauscher abtaut und die kalte Seite vom Kältemittelreislauf das Heizungswasser zwangsläufig abkühlt!to Defrosting phase becomes the coolant circuit vice versa, whereby now the warm refrigerant in the circulation Air heat exchanger defrosts and the cold side of the refrigerant circuit the heating water inevitably cool!

Dieses Problem wird mit dem im Schutzanspruch 1 aufgeführten Merkmalen gelöst.This Problem is solved with the features listed in the protection claim 1.

Mit der Erfindung wird erreicht, dass das Nutzmedium (z. B. Heizwasser) während der Abtauphase der Luftwärmepumpe nicht abgekühlt wird, da die 3. Wärmetauscherkammer speziell für das kalte Kältemittel keine direkte Wärmeübertragungsfunktion mit der Nutzwärmekammer (z. B. Heizwasser) hat!With the invention is achieved in that the useful medium (eg heating water) while the defrosting phase of the air heat pump not cooled will, since the 3rd heat exchanger chamber especially for the cold refrigerant no direct heat transfer function with the useful heat chamber (eg heating water) has!

Die Fließrichtung der Medien (z. B. Kältemittel) wird am 3-Zonen-Wärmetauscher mit Regelventilen bestimmt, die im Schutzanspruch 4 aufgeführt sind!The flow direction the media (eg refrigerant) is at the 3-zone heat exchanger determined with control valves, which are listed in the protection claim 4!

Ein Ausführungsbeispiel der Erfindung wird anhand von Zeichnungen schematisch dargestellt. Es zeigt:

  • – Fließschema Heizbetrieb: Medienkreislauf im Normalbetrieb (Heizen)
  • – Fließschema Abtaubetrieb: Medienkreislauf im Abtaubetrieb
An embodiment of the invention is illustrated schematically with reference to drawings. It shows:
  • - flow diagram heating mode: medium cycle in normal operation (heating)
  • - Flow scheme defrosting operation: media circulation in the defrosting operation

Die Fließschemen zeigen, dass ein direkter Wärmeaustausch der Medien nur im Heizbetrieb stattfindet!The flow charts show that a direct heat exchange the media only takes place in heating mode!
