| Outline of Final Research Achievements |
When soil contains an appropriate amount of water, its thermal conductivity increases dramatically under reduced air pressure. The dramatic increase in the thermal conductivity results from that individual soil pores function as micro heat-pipes, leading to a sequence of heat-pipe in the whole soil. Focusing on the possibility of the soil as a new material to transfer a large amount of heat, this study tries to develop a miniature heat-transfer devise that contains a mixture of soil and water. To evaluate the performance of the developed heat-transfer device, this study also makes a miniature greenhouse model that supposes summer. The performance evaluation reveals a possibility of the developed heat-transfer device to be a new technology for utilization of shallow geothermal energy.
