碩士 === 建國科技大學 === 土木與防災研究所 === 101 === The main principle of the Road Energy Systems is the asphalt absorbs solar energy heating the cold water into hot water. It can be used to melt ice in the winter, to reduce the road temperatures in the summer. In both hot and cold weather, it will produce energy. This study used concrete and the copper tube as the study material, and tried to simulate the road energy system but replacing asphalt concrete with normal concrete. The copper tube diameter used in this study were 5/16 inch, 3/8 inch, 1/2 inch, copper tube length were 9 meters and 18 meters, respectively. Concrete specimen is placed on the top floor, to get the maximum amount of sunlight. The temperatures at the surface and inside of the specimen, and the inlet and outlet water were measured. And using Stirling engine characteristics validate the development of new energy sources. Analysis of experimental data, although still not rotate the motor, but the experiment found that when the temperature reaches 6.6 ℃, the Stirling engine speed is 90.9 RPM, the temperature reached 12.3 ℃, the Stirling engine speed of 158 RPM. In this study, you can know for thermal energy into kinetic energy is feasible, but will require further kinetic energy into electrical energy research.
