Abstract
(A1) Die Erfindung betrifft einen Heiz- oder Kuehlkreislauf mit Waermequelle und Waermesenke, die ueber Hin- und Ruecklaufleitung miteinander verbunden sind, und mit einer Waermekraftmaschine zur Umwandlung thermischer Energie des Fluids im Kreislauf in mechanische und/oder elektrische Energie, wobei die Waermekraftmaschine ein Antriebselement aufweist, das seine aeussere Form mit seiner Temperatur aendert, wobei dem Antriebselement ein dem Kreislauf entnommener Fluidbetriebsstrom ueber eine Umschalteinrichtugn derart zufuehrbar ist, dass das Antriebselement alternierend mit Fluid aus der Hinlaufleitung und mit Fluid aus der Ruecklaufleitung beaufschlagbar ist.
DE 102007006146 A1 UPAB: 20080906 NOVELTY - The circuit has a heat source (1) and a heat sink (2) connected with each other by a supply pipe (3) and a return pipe (4). A heat engine (5) converts the thermal energy of a fluid into mechanical and electrical energy, where the heat engine has a drive section e.g. memory alloy element (9). The drive section is supplyable with a fluid operating current retained in the circuit over a converting device such that the drive section is alternatively subjectable with fluid from the supply pipe and the fluid from the return pipe. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for converting thermal energy of a heating or cooling circuit into mechanical and electrical energy. USE - Heating or cooling circuit for use with an electrical drive, an internal combustion engine, a turbine, and a fuel cell of motor vehicle, power station and heater, and in a building and a greenhouse. ADVANTAGE - The drive section is supplyable with the fluid operating current retained in the circuit over the converting device such that the drive section is alternatively subjectable with fluid from the supply pipe and the fluid from the return pipe, thus circulating the fluid in the heating or cooling circuit independently of the external supply of mechanical or electrical energy.
