Solar thermal system for converting solar energy into mechanical energy, has piston compressor pressing air that is compressed in absorber pipe of parabolic channel, where air is heated and expanded by solar radiation in piston engine

摘要

The system has a piston compressor (1) that presses air that is compressed in an absorber pipe (2) of a parabolic channel (3) with high pressure. The air is heated and expanded by solar radiation in a valve-controlled piston engine (4). The engine is connected with the compressor by a form-fitting connection (6) to drive the compressor. The piston engine is provided in a lower dead center after the expansion of the air, where a part of the mechanical energy of the engine is utilized by the form-fitting connection for driving the compressor.
