【摘要】：當今社會飛速發(fā)展,經濟高速提升,然而這些都是建立在大量的能源消耗的基礎上。通過片面的追求高速發(fā)展而舍棄環(huán)境顯然是不可取的。地源熱泵作為一種應用強、覆蓋寬、節(jié)能效果佳的高新技術,已被一些發(fā)達國家采用來減緩國內的能源危機,主要適用于城市中的居住建筑與大型的公共建筑,以及位于城郊的大型建筑如度假村等地區(qū)。近年來地源熱泵在我國不斷的發(fā)展與進步,符合我國可持續(xù)發(fā)展道路的既定方針,在我國的能源發(fā)展方面占有重要地位。論文通過全程參與某施工隊在徐州地區(qū)的地埋管換熱器熱響應測試,主要獲取了徐州地區(qū)某一商場的土壤的巖土層結構、土壤的換熱系數、土壤的初始溫度、冬夏兩季的工況以及管內阻力,這些參數對于之后的地源熱泵設計有很重要的參考作用。其中就各個測試的具體流程和測試原理進行了詳細的分析說明。論文先是詳細的介紹了地源熱泵的原理、特點以及分類,然后重點介紹了地埋管地源熱泵換熱性能的影響因素,根據這些影響因素針對性的提出排除影響因素的地下換熱器測試,包括是地下結構測試和地埋管換熱器熱響應測試。論文針對上述測試分別進行了測試內容的詳細介紹,重點剖析了測試原理,通過忽略軸向導熱量和各個影響因素之間的相互影響,對測試進行理論上的數值模擬,利用線熱源模擬和曲線的擬合進行數值計算,從而明確測試所需要的測試數據以及相應的方案。在確定好測試方案和測試儀器后,詳細介紹了測試步驟,透過對它的介紹來向闡明測試過程中應該注意的事項。論文最后對測試的數據進行科學的分析和總結,全面的說明了該地區(qū)土壤的熱物性、巖土層的構成以及管內阻力情況。整篇論文通過對地下結構測試和地埋管換熱器熱響應測試的詳細介紹,使得徐州地區(qū)今后的地源熱泵設計有更多的參考數據,同時也對其他地區(qū)熱響應測試有一定的借鑒作用。
[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.
