Abstract

The user can accept the primary energy with different or the same pressures and temperatures, whereby the type of energy carrier is freely selectable corresponding to requirements. Tubes are soldered, i.e. one tube for the primary circuit (3) and four tubes (2,4,6,7) for the various user units, bent into a coaxial spiral form. The centrally located tube (3) of the primary circuit is surrounded by the four tubes (2,4,6,7) for the various users.

Description

Gebiet der Wärmetechnik, im speziellen die Energieübertragung von einem Energiemedium auf ein anderes. Die Erfindung ermöglicht die direkte, und falls erforderlich gleichzeitige, Energieübertragung vom Primärenergieträger (z.B.: Kältemittel, Wasser, Dampf, Öl, oder Abgase) an die Energiemedien (z.B.: Wasser) mehrerer Verbrucher.Field of heat engineering, especially the energy transfer from one Energy medium to another. The invention enables direct, and if required simultaneous energy transfer from the primary energy source (e.g .: Refrigerants, water, steam, oil or exhaust gases) to the energy media (e.g. water) several consumers.

Die Nummern im folgenden Absatz beziehen sich auf Positionsnummern der Zeichnungen 1 und 2:
Zum derzeitigen Stand der Technik erfolgt die Versorgung mehrerer Verbraucher (1,2,3,4), deren Energielieferant ein und das selbe Medium ist, auf indirektem Wege über einen Primärkreis (5) und mehrere Sekundärkreise (Siehe Zeichnung 1). Ausgehend von mehreren Verbrauchern (1,2,3,4) ist bei dieser Lösung für die Versorgung derer, die voneinander unabhängig und völlig getrennten sind, ein erheblicher Aufwand erforderlich (Der erste Verbraucher ist hiervon ausgenommen). Man benötigt pro Verbraucher zusätlich einen Wärmetauscher (7,8,9), eine Umwälzpumpe (6) sowie diverse Armaturen (z.B.: Absperrventile, Rückschlagventile) und Regeleinrichtungen (Siehe markierter Bereich in Zeichnung 2). Durch die Verwendung eines zusätzlichen Wärmetauschers sinkt die Temperatur des Energiemediums des Verbrauchers um eine Temperaturdifferenz ΔT=TA1-TA2
The numbers in the following paragraph refer to item numbers in drawings 1 and 2:
At the current state of the art, several consumers (1, 2, 3, 4), whose energy is supplied by one and the same medium, are supplied indirectly via a primary circuit (5) and several secondary circuits (see drawing 1). Starting from several consumers (1,2,3,4), this solution requires considerable effort to supply those who are independent and completely separate (the first consumer is excluded from this). You also need a heat exchanger (7,8,9), a circulation pump (6) as well as various fittings (e.g. shut-off valves, check valves) and control devices (see marked area in drawing 2). By using an additional heat exchanger, the temperature of the consumer's energy medium drops by a temperature difference ΔT = TA1-TA2

Dieser übliche Aufbau kann aus der Fachliteratur (z.B.: Taschenbuch für Heizung und Klimatechnik von Recknagel Schrimmer Schramek erschienen im R.Oldenburgverlag oder Wärmeaustauscher von Walter Wagner erschienen im Vogl Verlag oder Industrial Heat Exchangers von A.J.Hayes, W.W.Liang, S.L.Richlen and E.S Tabb herausgegeben von American Society for Metals oder weiters Design and Operation of Heat Exchangers von W.Roetzel, P.J. Heggs und D.Butterworth erschienen im Springerverlag) entnommen werden. This usual structure can be found in the specialist literature (e.g .: paperback for heating and Air conditioning technology from Recknagel Schrimmer Schramek was published by R.Oldenburgverlag or heat exchangers from Walter Wagner published by Vogl Verlag or Industrial Heat Exchangers by A.J. Hayes, W.W. Liang, S.L. Richlen and E.S Tabb edited by American Society for Metals or further Design and Operation of Heat Exchangers by W. Roetzel, P.J. Heggs and D.Butterworth appeared in Springerverlag) are removed.

Die Nummern in den 3 folgenden Absätzen beziehen sich auf Positionsnummern der Zeichnung 3:
Diese Erfindung ermöglicht die direkte und gleichzeitige Energieübertragung auf mehrere, absolut getrennte und unabhängig arbeitende, Verbraucher (1,2,3,4). Weiters ermöglicht die Erfindung den Verzicht auf den pro Verbraucher zusätlichen Aufwand von Wärmetauscher, Umwälzpumpe, diversen Armaturen und Regeleinrichtungen (Siehe markierter Bereich in Zeichnung 2). In der Folge des Wegfallens des zusätlichen Wärmetauschers und der Umwälzpumpe erhöt sich zum einen der Wirkungsgrad entsprechend und weiters die Temperatur des Energiemediums des Verbrauchers um ΔT. (Der erste Verbraucher ist hiervon wiederum ausgenommen).
The numbers in the following 3 paragraphs refer to item numbers in drawing 3:
This invention enables the direct and simultaneous transmission of energy to several, absolutely separate and independently operating consumers (1, 2, 3, 4). Furthermore, the invention makes it possible to dispense with the additional expenditure of heat exchanger, circulation pump, various fittings and control devices per consumer (see marked area in drawing 2). As a result of the elimination of the additional heat exchanger and the circulating pump, the efficiency increases, on the one hand, and the temperature of the energy medium of the consumer increases by ΔT. (The first consumer is again exempt from this).

Es entsteht durch die Erfindung die Möglichkeit mehrere Verbraucher (1,2,3,4) auf die selbe Temperatur zu erwärmen. Man kann zum Beispiel mit der Energie die in einem Kondensationskreis einer Wärmepume zur Verfügung steht, ohne Anwendung eines zusätzlichen Wärmetauschers, wie bisher erforderlich, das Gebrauchswarmwasser und das Heizungswasser erwärmen, und darüber hinaus auf die gleiche Temperatur.The invention creates the possibility of multiple consumers (1, 2, 3, 4) on the to heat the same temperature. You can, for example, with the energy in one Condensation circuit of a heat pump is available without using a additional heat exchanger, as previously required, the domestic hot water and heat the heating water, and also to the same temperature.

Ferner erlaubt die Erfindung einen wesentlich einfacheren Aufbau der Anlage und somit beträchtliche Kostenersparnisse. Furthermore, the invention allows a much simpler structure of the system and thus considerable cost savings.
