Problems solved by technology

Chinese patent 200910175484.2 "Trough solar thermal power generation device" uses a variety of gases including carbon dioxide gas as the heat transfer medium. Compared with the supercritical Brayton cycle power mode, this technical solution has obvious defects. The key is that it does not play carbon dioxide. The advantage of low critical point, in order to further improve the thermoelectric efficiency, it should be transformed into a supercritical Brayton cycle power generation mode
