【摘要】：当今社会飞速发展,经济高速提升,然而这些都是建立在大量的能源消耗的基础上。通过片面的追求高速发展而舍弃环境显然是不可取的。地源热泵作为一种应用强、覆盖宽、节能效果佳的高新技术,已被一些发达国家采用来减缓国内的能源危机,主要适用于城市中的居住建筑与大型的公共建筑,以及位于城郊的大型建筑如度假村等地区。近年来地源热泵在我国不断的发展与进步,符合我国可持续发展道路的既定方针,在我国的能源发展方面占有重要地位。论文通过全程参与某施工队在徐州地区的地埋管换热器热响应测试,主要获取了徐州地区某一商场的土壤的岩土层结构、土壤的换热系数、土壤的初始温度、冬夏两季的工况以及管内阻力,这些参数对于之后的地源热泵设计有很重要的参考作用。其中就各个测试的具体流程和测试原理进行了详细的分析说明。论文先是详细的介绍了地源热泵的原理、特点以及分类,然后重点介绍了地埋管地源热泵换热性能的影响因素,根据这些影响因素针对性的提出排除影响因素的地下换热器测试,包括是地下结构测试和地埋管换热器热响应测试。论文针对上述测试分别进行了测试内容的详细介绍,重点剖析了测试原理,通过忽略轴向导热量和各个影响因素之间的相互影响,对测试进行理论上的数值模拟,利用线热源模拟和曲线的拟合进行数值计算,从而明确测试所需要的测试数据以及相应的方案。在确定好测试方案和测试仪器后,详细介绍了测试步骤,透过对它的介绍来向阐明测试过程中应该注意的事项。论文最后对测试的数据进行科学的分析和总结,全面的说明了该地区土壤的热物性、岩土层的构成以及管内阻力情况。整篇论文通过对地下结构测试和地埋管换热器热响应测试的详细介绍,使得徐州地区今后的地源热泵设计有更多的参考数据,同时也对其他地区热响应测试有一定的借鉴作用。
[Abstract]:Nowadays, the society is developing rapidly and the economy is improving rapidly. However, these are based on a large amount of energy consumption. It is obviously not desirable to abandon the environment through the unilateral pursuit of high-speed development. As a kind of high and new technology with strong application, wide coverage and good energy-saving effect, ground-source heat pump has been adopted by some developed countries to alleviate the domestic energy crisis. It is mainly suitable for residential buildings and large public buildings in cities. And in the suburbs of large buildings such as resorts and other areas. In recent years, the development and progress of ground-source heat pump in China is in line with the established policy of sustainable development in China, and plays an important role in the energy development of China. By participating in the thermal response test of a construction team in Xuzhou area, the paper obtains the structure of the soil, the heat transfer coefficient of the soil, the initial temperature of the soil in a shopping mall in Xuzhou area. These parameters are very important for the design of ground source heat pump in winter and summer. The detailed analysis and explanation of each testing process and test principle are given. Firstly, the principle, characteristics and classification of ground-source heat pump are introduced in detail, and then the influencing factors of heat transfer performance of ground-source heat pump are introduced. According to these factors, the paper puts forward the test of underground heat exchanger, including underground structure test and underground tube heat exchanger thermal response test. In this paper, the testing contents of the above tests are introduced in detail, and the testing principle is analyzed, and the theoretical numerical simulation of the test is carried out by ignoring the interaction between the axis guide heat and the influencing factors. The line heat source simulation and curve fitting are used to calculate the test data and the corresponding scheme. After determining the test scheme and the test instrument, the test steps are introduced in detail, and the points that should be paid attention to in the testing process are explained through the introduction of the test procedure. At the end of the paper, the test data are scientifically analyzed and summarized, and the thermal properties of the soil, the composition of the rock and soil layer and the resistance in the pipe are explained comprehensively. Through the detailed introduction of underground structure test and heat response test of underground heat exchanger, the design of ground source heat pump in Xuzhou area has more reference data in the future, at the same time, it can also be used for reference in other areas.
