PURPOSE: A scroll expander for electric power generation system using solar energy as the energy source is provided to heat a first working fluid using solar energy, that is the energy source, and to generate power by recovering the heat energy of second working fluid into a shaft power by means of the scroll expander of organic rankine cycle which circulates the second working fluid by the heat exchange of the first working fluid, thereby producing the high efficient electricity. CONSTITUTION: A scroll expander for electric power generation system using solar energy as the energy source includes an absorber plate (200), a pressure tank (300), a heat-exchanger (400), a first pump (500), a scroll expander (600), a condenser (700), a surge tank (800), and a second pump (900). The absorber plate heats the first working fluid to high temperature with solar energy. The pressure tank is filled with the first working fluid heated by the absorber plate. The heat-exchanger exchanges heat with the second working fluid by circulating the first working fluid in high temperature and pressure of the pressure tank. The first pump forcedly injects the first working fluid, which is passed through the heat-exchanger, into the absorber plate. The scroll expander converts the heat energy of second working fluid, which is heat-exchanged by the heat-exchanger, into the shaft (1a) force of a generator (1). The condenser cools the second working fluid passed through the scroll expander. The surge tank is filled with the second working fluid which is passed through the condenser and is in a cool state. The second pump forcedly injects the second working fluid of the surge tank into the heat-exchanger. [Reference numerals] (100) Solar heat; (200) Absorber plate |
