Abstract
Description
Erdwärmesonden dienen dazu Energie aus dem Erdreich aufzunehmen um diese mit Hilfe einer Wärmepumpe für Heizzwecke nutzbar zu machen.geothermal probes serve to absorb energy from the soil around them with the help a heat pump for heating purposes to make usable.
Es gibt unterschiedliche Bauarten von denen die nachfolgend beschriebene vorwiegend eingesetzt wird, da sie durch ihren Aufbau am kostengünstigsten ist, und praktisch wartungsfrei arbeitet.It There are different types of those described below is used mainly because they are the most cost-effective due to their structure is, and practically maintenance-free works.
Stand der Technik sind zwei glattwandige Kunststoffrohre als Vor- beziehungsweise Rücklauf, die am unteren Ende über den Sondenfuß miteinander verbunden sind. In der Sonde zirkuliert die sogenannte Soleflüssigkeit, ein Gemisch aus Wasser und Frostschutzmittel.was standing The technology is two smooth-walled plastic pipes as a fore or Rewind, the over at the bottom the probe foot together are connected. The so-called brine liquid circulates in the probe a mixture of water and antifreeze.
Die Soleflüssigkeit dient dem Energietransport, sie nimmt Wärmeenergie im Bohrloch auf und gibt diese über einen Wärmetauscher in den Kreislaufprozess der Wärmepumpe ab.The Sole liquid is used for energy transport, it absorbs heat energy in the borehole and give these over a heat exchanger in the circulation process of the heat pump from.
Für eine wirtschaftliche Betriebsweise der Wärmepumpe ist unter anderem die Übertragung der Wärmeenergie vom Erdreich zur Soleflüssigkeit ein wichtiges Kriterium. Dabei spielt die Art der Durchströmung eine entscheidende Rolle. Die optimale Energieübertragung findet statt, wenn die Sonde von der Soleflüssigkeit turbulent durchströmt wird. Die lineare Durchströmung ist aufgrund ihrer schlechten Wärmeübertragung zu vermeiden.For an economic Operation of the heat pump is among other things the transmission the heat energy from soil to brine an important criterion. The type of flow plays a role decisive role. The optimal energy transfer takes place when the probe from the brine liquid flows through turbulent becomes. The linear flow is due to their poor heat transfer to avoid.
Um in glattwandigen Rohren eine turbulente Strömung zu erreichen, müssen Strömungsgeschwindigkeit, Umlaufmenge und Rohrdurchmesser berechnet werden. In der Praxis wird diese relativ aufwändige Berechnung nicht immer durchgeführt, teilweise ist die Problematik auch gar nicht bekannt.Around to achieve a turbulent flow in smooth-walled pipes, flow velocity, Circulating quantity and pipe diameter are calculated. In practice This will be relatively expensive Calculation not always done, partly the problem is not known.
Der Erfindung liegt die Aufgabe zugrunde eine Sonde zu entwickeln die unabhängig von Strömungsgeschwindigkeit, Umlaufmenge oder Rohrdurchmesser turbulent durchströmt wird.Of the Invention has for its object to develop a probe the independently of flow velocity, Circulating flow or pipe diameter is traversed turbulently.
Dies wird in der Erfindung dadurch erreicht, indem das innen glattwandige Rohr durch ein Rohr ersetzt wird, das innen ein Profil erhält das als Schraubenlinie oder zylindrische Spirale bezeichnet wird. Diese zylindrischen Spiralen kommen zum Beispiel in den Läufen von Feuerwaffen vor und werden dort als Züge bezeichnet.This is achieved in the invention by the inside smooth-walled Pipe is replaced by a pipe that gets a profile inside as a helix or cylindrical spiral is called. These cylindrical spirals come for example in the runs of firearms and are referred to as trains.
Diese Profilgebung bewirkt in jedem Fall eine turbulente Strömung ohne aufwändige Berechnung, der Wärmeübergang auf die Soleflüssigkeit kann optimal erfolgen.These Profiling in any case causes a turbulent flow without complex Calculation, the heat transfer on the brine liquid can be done optimally.
