土壤源热泵的研究与开发

R & D of Ground Source Heat Pump

土壤源热泵是利用地下土壤能源资源来进行供暖空调的一种高效、节能、环保型空调技术,近年来得到了快速的发展;文章介绍了它的国内外研究状况,分析了土壤的传热特性、土壤的温度分布状况及埋地盘管的传热特性,建立了埋地盘管的传热数学模型,指出了土壤源热泵研究与发展中的关键性问题,最后展望了其应用前景。

GSHP is a air-conditioning technique with energy saving & envionment protecting using earth energy, and is developed rapidly these days. This paper introduces it's research situation in home and oversea. The heat transfer characteristic of soil and buried ground heat exchanger and temperature distribution of soil are analyzed. The heat transfer model of ground heat exchanger is established. The key points of R & D about GSHP is pointed out. The development prospect on GSHP is also elaborated.
