Engine powered from solar energy - has freon filled solar panels with cold water heat exchange systems

摘要

The solar heat engine (5) uses Freon (RTM) as a working fluid which receives heat from the heat exchangers (12, 15). One heat exchanger (12) is supplied with heat from water which has been heated by one Freon filled solar panel and circulated by pump (3). The other heat exchanger (15) receives heat from another Freon filled silar panel (2). The Freon (RTM) leaving the engine (5) flows into the heat exchanger (18) where it releases its residual heat. It is then pumped (20) to the constant head tank (21) and returns to the heat exchanger (12). The Freon cooling heat exchanger (18) is cooled by the water system circulated from the old tank (28) which loses heat at night due to the water flowing through the radiator (31) which radiates heat to the atmosphere.
