能源隧道传热与设计方法研究

Buried pipe heat exchanger is a series of heat lines with heat pump installed in tunnel lining in certain depth. The heat exchanger can solve two major obstacles, land occupation and high cost in traditionally vertical and horizontal ground heat exchanger system. Different from the traditional vertical and horizontal buried ground heat exchangers, the heat transfer of energy tunnel will be affected by heat physical properties of surrounding rock, ground temperature, groundwater seepage velocity, air temperature and ventilation in tunnel, and other factors. Based on the thermal physical parameters of soil and its influence on heat transfer energy tunnel, energy and heat transfer model and the calculation method of tunnel, the energy tunnel design method and energy tunnel engineering in the domestic application are introduced, this technology has broad application prospect in our country.
