具有无污染、可再生、分布广、能量大以及可就近利用等诸多优势的浅层地温能是一种建筑节能的洁净能源,具有广泛的应用前景。根据关中盆地主要城市工程地质、水文地质、环境地质条件等因素,分别建立了每个城市地下水热泵和地埋管热泵系统的适宜分区评价体系,并进行了适宜性综合分区。基于适宜性分区评价结果,对主要城市进行了浅层地热能资源量评价,包括热容量计算、换热功率计算和热能潜力计算,旨在有效地丰富浅层地温能勘察评价与开发利用的理论、奠定浅层地温能广泛开发利用的基础,为改善我国现有能源结构、构建环境友好型社会和节能减排的目标服务。 相似文献

浅层地温能作为地热学新的分支,其资源特征、评价方法与传统地热存在差异。本文从传统"地热能"与"浅层地温能"的科学内涵入手指出两者的相互关系,对比分析了资源分布规律、资源赋存条件评价方法、资源潜力评价方法。浅层地温能资源分布边界依据地质条件、地理分布和应用目的而相应变化,主要受浅层地温场控制;浅层地温能资源赋存条件评价与传统地热评价过程不完全一致,资源适宜区划分受到开发利用方式的限制,浅层地温能资源的计算实际是对地球浅表热量调蓄能力的评价。浅层地温能和地热资源评价的区别与联系,凸出了浅层地温能资源的特殊性,提高了热能资源勘查评价的科学性和合理性。 相似文献

由于对地质条件的不甚了解,导致目前一些本应节能的地源热泵项目并不节能,甚至一些本不适宜开发利用浅层地温能的地区,居然成了开发利用示范区。中国地调局浅层地温能研究与推广中心总工程师冉伟彦表示,浅层地温能的开发利用方式要根据不同地区对供暖和制冷的不同需求,更要根据一个地区的地质条件而定—— 相似文献

In the recent decade, the construction projects related to shallow geothermal energy engineering have undergone rapid development in Shandong Province. The predominant type of these developments and applications was heat exchange through buried tubes and the main targets were residential and office buildings. However, an overwhelming majority of the completed geothermal heat pump projects lacked monitoring devices so that they were unable to comprehensively reflect the background values for the geothermal fields within the province and few researches were conducted on their influence on the geological environment. In this paper, locations for monitoring shallow geothermal energy and their validity of the monitoring point deployment were studied in view of the development and application status as well as geological background conditions of various projects located in multiple cities providing data support for analyzing the fluctuation trend and influence of large-scale shallow geothermal energy applications on the shallow geothermal and the feasibility and parameter designs of newly built systems in Shandong Province in the future. 相似文献

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。 相似文献

In this paper,through data collection and field investigation,the development and utilization status of shallow geothermal energy in Zhoukou urban area was discussed.Based on the analysis of hydrogeological conditions,rock and soil structure characteristics and field test research,the spatial distribution characteristics of rock and soil in the study area were summarized.The study shows that Zhoukou City is located in the alluvial plain of Huanghuai,and the loose deposits of river alluvial genesis range 0-200 m.These loose deposits and groundwater stored in their pores are the main carriers of shallow geothermal energy.In the central part of the Yinghe River in the middle of the study area,the aquifer thickness is within 200 m,the particle size is coarser,the water-bearing degree and recharge capacity is better.On this basis,the paper uses AHP to evaluate the suitability of shallow geothermal energy development and utilization to guide the rational development and utilization of shallow geothermal energy resources. 相似文献
