EXPERIMENTAL RESEARCH AND SIMULATION BY SOIL COLD STORGE USING NATURAL ENERGY
Present a new technique of using natural cold source, and research change of temperature around soil, energy efficiency coefficient of this system in two phases of storing cold and extracting cold, and establish mathematics model of heat conductivity of U-tube, and simulate the soil temperature field around vertical tube. In experimental procedure, average effect radius of soil heat exchanger was about 3m and energy efficiency coefficient of this system was 2～3 times those of traditional air-conditioning systems.
