【 摘 要 】

In this paper, a new kind of power generation system was built, which took solar energy as heat source of the system. All heat exchangers in the system adopted a new kind of heat exchanger type-Printed Circuit Heat Exchanger (PCHE). In order to take advantage of the abrupt property changes near the critical point of carbon dioxide, we selected recompression Brayton cycle. Then, given the operating conditions, the optimization progress was performed and the optimized parameters were obtained.
