Abstract
Description
Solche bekannten Wärmetauscher werden meist in Niedrigenergie-Häusern verwendet, die mit einer Wärmepumpe und Solaranlagen ausgerüstet sind. Sie haben aber meist den Nachteil, dass ihr Frischwasser auf eine viel zu hohe Temperatur aufgeheizt wird, so zwischen 70 bis 80°Celsius, was nicht nur zu einem großen Energieverlust, sondern auch zu verstärkten Kalkablagerungen und zu Rohrkorrosion führt. Kürzere Wartungsintervalle sind dann notwendig.Such known heat exchanger are mostly found in low energy houses used with a heat pump and solar systems are equipped. However, they usually have the disadvantage that their fresh water is limited to one the temperature is much too high, between 70 and 80 ° Celsius, which is not just a big one Energy loss, but also to increased limescale deposits and leads to pipe corrosion. shorter Maintenance intervals are then necessary.
Der Erfindung liegt die Aufgabe zugrunde, die aufgezeichneten Nachteile zu vermeiden und einen Wärmetauscher zu schaffen, bei dem das Frischwasser gewöhnlich nur auf 40°C aufgeheizt wird. Das spart Energie und mindert Kalkablagerungen. In besonderen Fällen, vorzugsweise im Sommer, soll aber auch eine höhere Frischwasser-Temperatur zumindest kurzzeitig zu erreichen sein. Schließlich sollen auch die Legionellen pneumophila, die Legionärslσankheits-Erreger, in Schach gehalten werden, die in Warmwasserleitungen auftreten können.The Invention is based on the object, the recorded disadvantages to avoid and a heat exchanger to create, in which the fresh water usually only heated to 40 ° C. becomes. This saves energy and reduces limescale. In particular cases preferably in summer, but should also have a higher fresh water temperature can be reached at least for a short time. Finally, the legionella are said to be pneumophila, the Legionnaire's disease pathogen, kept in check that occur in hot water pipes can.
Diese Aufgabe wird gemäß der Erfindung gelöst durch die kennzeichnenden Merkmale des Hauptanspruches. Vorteilhafte Weiterbildungen des Gegenstandes des Ausspruches 1 ergeben sich aus den Merkmalen der Unteransprüche, sowie aus der Beschreibung und der Zeichnung.This Object is according to the invention solved by the characterizing features of the main claim. advantageous Developments of the subject matter of the saying 1 result from the characteristics of the subclaims, as well as from the description and the drawing.

Als Vorteil der erfindungsgemäßen Einrichtung sind zu nennen:As Advantage of the device according to the invention are to be mentioned:
-
1. Durch die Erfindung des eutektischen Trägermediums
18 in einem Temperaturbereich zwischen 45°C bis 55°C erhöht sich durch den Eintrag latenter Energie die Kapazität des Trägermediums um etwa 50%, was sich positiv auf die Temperaturstabilisierung bei der Frischwassererwärmung auswirkt. Durch die Verwendung zweier in Reihe hintereinander geschalteter Wärmeübertrager zur Frischwassererwärmung, (in jeweils indirekter Energieübertragung), ist die Erzeugung von frischem Warmwasser ausreichend sichergestellt.1. With the invention of the eutectic carrier medium18 in a temperature range between 45 ° C to 55 ° C, the latent energy input increases the capacity of the carrier medium by about 50%, which has a positive effect on the temperature stabilization during fresh water heating. The use of two heat exchangers connected in series for fresh water heating (each with indirect energy transfer) ensures that fresh hot water is generated. - 2. Da die Vorhaltetemperatur von etwa 40°C sehr nieder ist, ist die Einrichtung für den Einsatz von Wärmepumpen besonders geeignet. Eine hohe Arbeitszahl (COP-Wert) der Wärmepumpe ist somit ermöglicht. Damit können die Wärmeübertrageroberflächen deutlich kleiner ausgeführt werden als beim Stand der Technik.2. Since the reserve temperature of about 40 ° C is very low, the device is for the Use of heat pumps particularly suitable. A high coefficient of performance (COP value) for the heat pump is thus possible. So that can the heat exchanger surfaces clearly executed smaller than in the prior art.
- 3. Ganz wichtig ist es, dass es für temporäre Anwendungen nun möglich ist, die Erwärmung des Frischwassers auf eine Temperatur zu bringen, die deutlich über der Trägermedium-Temperatur liegt und somit die Wirtschaftlichkeit enorm gesteigert wird.3. It is very important that it is now possible for temporary applications the warming of the fresh water to a temperature that is significantly higher than the Carrier medium temperature is and thus the profitability is increased enormously.
- 4. Im direkten Austausch von Frischwasser zum überhitztem Kältemittel von 75°C bis 85°C wird das Legionellenproblem elegant gelöst.4. In the direct exchange of fresh water for superheated refrigerant of 75 ° C up to 85 ° C the legionella problem is solved elegantly.
