【摘要】 概述了地源热泵的发展背景,通过与传统空调系统进行比较从一次能源利用率、供暖成本、能效比、污染物排放量4个方面分析了地源热泵的优越性,详细阐述了地源热泵的性能系数受土壤、岩土、原始地温、日照强度、回填材料、埋管形式、循环流量、管间距、管材等因素的影响,提出了地源热泵在发展过程中应注意土壤、回填材料热物性、热短路等问题的研究,探讨加快地源热泵发展的有效措施如收集地源热泵设计的相关资料、研究热泵空调系统的配套设施、选择适当的管间距、系统间隔运行、管群之间交叉运行或增设辅助设备等。更多还原

【Abstract】 The development background and advantage about GSHP(Ground Source Heat Pump) are introduced.Particularly some correlative factors about performance of GSHP are set forth such as ground,original ground temperature,solar radiation rate,backfill materials,buried-pipe type,circulating flow,pipe spacing,pipe material.Problem of soil,thermolphysical nature of backfill materials,heating short-circuiting is brought forward in the development of GSHP.Effective measures to improve the development of GSHP is presented such as collection of material,equipment companion,moderate pipe spacing,interval running,interchange running or addition of auxiliary equipment.更多还原
