The device for detecting and evaluating the processes of the heat charge and heat release of the heat capacitor is characterized in that the device comprises a first conduit (1), an air compressor (2), an air-drying filter (3), an air preheater (4), an air heater (5), an electrical control flow adjusting valve (6), a first flow indicator (7), a second flow indicator (9), a first temperature pressure sensor (11), a computer (12), a second temperature pressure sensor (13), a third temperature pressure sensor (14) and a second conduit (15), wherein, the first conduit (1) is provided with the air-drying filter (3), the air preheater (4), the air heater (5), the electrical control flow adjusting valve (6) and the first flow indicator (7) in sequence; the second conduit (15) is provided with the second flow indicator (9). The device has simple structure and easy operation and can detect and evaluate the index of the heat accumulation efficiency, the security and the durability in the processes of heat charge and heat release of the heat capacitor.

Description

technical field [0001] The invention relates to a performance index test and evaluation device for the heat charging and heat releasing process of a heat storage device in solar thermal power generation. Background technique [0002] Using solar energy for thermal power generation, due to the influence of weather conditions such as seasons, day and night, cloud, fog, rain and snow, the solar energy on the ground is intermittent and unstable, so a heat storage device must be installed. [0003] To design different heat storage devices for different needs, it is necessary to test the heat charging and heat release process of the heat storage device to verify its safety and durability, and optimize and improve the design of the heat storage device according to the experimental data. [0004] But there is no simple and easy-to-operate test and evaluation device that can perform experimental tests on different heat storage devices. Contents of the invention [0005] The purpos...
