Abstract: The optical performance of the solar thermal power device has an important influence on its total working efficiency. In this paper, the Monte Carlo ray trace method is used to simulate the optical performance of the designed solar air compressor system. In order to analyze the energy density distribution on the receiver and the optical efficiency of the solar air compressor, the geometrical model of the main optical components including the point-focusing Fresnel lens, quartz glass window, and heating pipe have been built using Tracepro software. The results show that the energy density distribution on the interior surfaces of the heating pipe is extremely non-uniform. What’s more, when the length of the heat absorption tube is increased, the diameter of the light hole is reduced, and the absorption rate of the heat pipe inner surface is increased, the optical efficiency of the system and the light-to-heat conversion performance will be improved.
