| 摘 要： | 深入研究高寒地区建筑物供暖制冷需求及浅层地温能开发利用条件,可发挥浅层地温能在建筑能源供应中的最大效益; 探讨多种能源在供暖中的联合应用,能够更好地解决高寒地区能源紧缺问题。通过对高原气候特点分析,浅层地温能开发利用条件的调查、勘探、评价及多种能源联用的研究认为: 高寒地区对浅层地温能需求主要为冬季供暖和生活热水供应,且热量需求大; 高寒地区浅层地温能资源品位低,主要体现为换热温差小; 换热方式以地下水水源热泵最为经济实用; 城市中可供开发利用的空间小。鉴于当地深部地热、太阳能资源丰富,可充分利用这些可再生能源及常规能源,尽可能采用“基础负荷+调峰负荷”的方式,解决热量需求大的问题,从而提高能源的利用效率。

| Abstract: | This research focuses on the heating and cooling demand of the buildings and the development and utilization conditions of shallow geothermal energy in alpine region, which would promlte the maximum use of shallow geothermal energy in energy supply of buildings. In addition, it explores the aombined application of multiple energy in supply heating to better solve the energy shortage problem in alpine region. The authors analyzed the plateau climate characteristics, and did research on the investigation, exploration, evaluation of shallow geothermal energy and combined application of multiple energy. The results show that shallow geothermal energy is mainly used for winter heating and hot water supply in alpine region, and the demand is great. The resource grade of shallow geothermal energy in alpine region is low with little heat transfer temperature difference. The most economical mode of heat exchanging is groundwater source heat pump, and there is little space for the development and utilization of shallow geothermal energy in cities. The deep geothermal energy and solar energy are abundant in the study area, and these resources could be fully utilized through the way of basic load and peak-regulating load to solve the problem of great heat demand and improve energy utilization efficiency. |
