Abstract

The method involves liquefying cooled thermal fluid in a condenser (5) after flowing through a turbo-engine (3). The thermal fluid is fed through a pressure build-up unit (6) back to an evaporator (1), where the turbo-engine includes a generator (4), which generates electrical energy. The turbo-engine is formed as a modified scroll compressor, which rotates backwards and operates as an expansion machine, a brushless direct current (BLDC) motor and a generator. A controllable valve (2) is located with opening and closing of start of the expansion engine. The thermal fluid is selected from chlorofluorocarbons (CFC) and hydrofluorocarbon (HFC) refrigerants such as 1, 1, 1, 2-Tetrafluoroethane. An independent claim is also included for a device for producing electric energy from solar energy.

Aus vielen Veröffentlichungen sind Organic Ranking Cycle Systeme bekannt (z. B. DE 101 26 403 A1 ), die die Erzeugung elektrischer Energie aus Wärme- beziehungsweise Solarenergie erlauben. In vielen Veröffentlichungen sind Turbinen/Generator-Varianten erwähnt, die sich auf Turbinen oder Kolbenmaschinen als Expansionsmaschinen beziehen (z. B. WO 2007/042215 A1 .From many publications Organic Ranking Cycle Systems are known (eg. DE 101 26 403 A1 ), which allow the generation of electrical energy from heat or solar energy. Many publications mention turbine / generator variants which refer to turbines or piston engines as expansion engines (eg. WO 2007/042215 A1 ,

In dem vorliegenden Verfahren wird als Expansionsmaschine/Generator-Kombination auf existierende Scroll-Kompressoren der Klima/Kältetechnik zurückgegriffen, wobei der Scroll-Kompressor durch Rückwärtsdrehen als Expansionsmaschine/Generator Kombination eingesetzt werden kann. Hierbei sind solche in Scroll-Kompressoren eingesetzten Baugruppen zu entfernen, die ein Rückwärtsdrehen vermeiden, wie Rückschlagventile oder zum Beispiel Fluid-Breaks. Desweiteren ist statt eines Asynchronmotors ein BLDC-Motor einzusetzen, dessen Rotor Permanent-Magnete beinhaltet, um als Generator zu wirken.In The present method is called an expansion machine / generator combination resorting to existing air conditioning / refrigeration scroll compressors, wherein the scroll compressor by reverse rotation can be used as an expansion machine / generator combination. Here, such assemblies used in scroll compressors to remove, which prevent a reverse rotation, such as check valves or, for example, fluid breaks. Furthermore instead of an asynchronous motor, use a BLDC motor whose Rotor includes permanent magnets to act as a generator.

Durch ein steuerbares Ventil auf der Hochdruckseite vor dem Kompressor kann ein entsprechender erforderlicher Anlaufdruck abgewartet werden, befor das Ventil (2) geöffnet wird und der Kompressor anläuft.A controllable valve on the high-pressure side in front of the compressor can be used to wait for the required starting pressure before the valve ( 2 ) is opened and the compressor starts.

Diese Kombination von einer Scroll-Expansionsmaschine mit BLDC-Motor als Generator läßt sich mit geringen Aufwänden auf Produktionsanlagen für die Scroll-Kompressor Fertigung herstellen. Aufgrund der für die Scroll-Kompressoren im Bereich Klima-/Kältetechnik eingesetzten Baugruppen sind alle Baugruppen für den Einsatz unter entsprechenden Drücken und für viele einsetzbare FCKW/FKW-Kältemittel bereits ausgewählt und qualifiziert.These Combination of a scroll expansion engine with BLDC motor as Generator can be with little effort on production equipment for the scroll compressor manufacturing produce. Due to the scroll compressors in the Are used in the field of air conditioning / refrigeration all assemblies for use under appropriate pressures and for many usable CFC / HFC refrigerants already selected and qualified.
