【摘要】：地埋管地源热泵系统作为地源热泵空调技术中的主导形式,有着非常好的节能和环保效益,并且在一定程度上避免了诸如地下水地源热泵系统对地下水资源的负面影响,因此在我国得到了广泛的研究和应用。但是地埋管地源热泵系统初投资很高,系统较为庞大,对场地的要求也较高,对于实际的工程来说,选择地埋管地源热泵系统到底节约多少常规能源,实现多少二氧化碳减排量等问题都是需要分析的,如果盲目采用,不仅达不到理想的运行效果,甚至不能够正常运行,对能源和资源都是严重的浪费。因此,有必要综合归纳该系统的节能效益、环保效益、经济效益和技术效益,建立一套比较完善的地埋管地源热泵系统性能评价体系。这正是本文研究的背景和出发点。本文从地埋管地源热泵系统的运行原理、特点和实际应用入手,将地源热泵系统的主要影响因素归纳并建立综合评价指标的递阶层次结构,通过层次分析法,得出各指标的权重。并利用SPSS软件基于多元线性回归分析的原理,建立某些已知分指标与其对应的二级指标之间的预测公式。通过层次分析法与多元线性回归分析相结合,最后建立目标层即地埋管地源热泵系统综合性能评价指标的预报方程。通过二级指标层的各个因子的实际值,预测得到目标层即地源热泵系统综合评价指标。本文通过总结地源热泵系统相关的规范标准,建立了地埋管地源热泵系统性能评价指标得分体系,并通过目标层的预测公式最终得到了地源热泵系统综合性能评价指标分数。通过对具体实际工程的评价,本文得出地埋管地源热泵系统在节能方面效果显著。经济方面,初投资尤其是钻孔费用较大。环保方面,可以有效提高温室气体减排量、粉尘减排量等,减少对大气的污染程度。但是对地下水的热稳定会产生一定的负面影响。本课题的研究结论对各地区开展地源热泵技术的应用有所参考,可以引导地源热泵的健康发展,推动可再生能源的因地制宜、合理利用。同时对实际工程中地源热泵系统的合理设计也有一定的参考价值。
[Abstract]:As the dominant form of ground-source heat pump air conditioning technology, ground source heat pump system has very good energy saving and environmental protection benefits, and to some extent avoids the negative impact on groundwater resources caused by ground-source heat pump system. Therefore, it has been widely studied and applied in our country. But the initial investment of ground source heat pump system is very high, the system is relatively large, and the demand for the site is also high. For the actual project, how much conventional energy is saved by choosing the ground source heat pump system? It is necessary to analyze how much carbon dioxide emission reduction can be achieved. If it is blindly adopted, it will not only fail to achieve the ideal operation effect, but also can not operate normally, which is a serious waste of energy and resources. Therefore, it is necessary to synthetically sum up the energy saving, environmental protection, economic and technical benefits of the system, and establish a set of relatively perfect evaluation system for the performance of ground-source heat pump system. This is the background and starting point of this paper. Starting with the operation principle, characteristics and practical application of the ground source heat pump system, the main influencing factors of the ground source heat pump system are summarized and the hierarchical structure of the comprehensive evaluation index is established. The weight of each index is obtained. Based on the principle of multivariate linear regression analysis, SPSS software is used to establish the prediction formula between some known sub-indexes and their corresponding second-order indexes. Through the combination of analytic hierarchy process (AHP) and multivariate linear regression analysis, the prediction equation of the comprehensive performance evaluation index of ground source heat pump (GSHP) system is established. Through the actual values of each factor in the secondary index layer, the target layer, i.e., the comprehensive evaluation index of the ground-source heat pump system, is predicted. In this paper, the performance evaluation index scoring system of ground-source heat pump system is established by summarizing the relevant specifications of ground-source heat pump system, and the score of comprehensive performance evaluation index of ground-source heat pump system is obtained by the prediction formula of target layer. Through the evaluation of practical projects, this paper draws the conclusion that the ground source heat pump system has remarkable effect on energy saving. In economic terms, initial investment, especially drilling, is expensive. In the aspect of environmental protection, greenhouse gas emission reduction and dust emission reduction can be effectively increased, and the degree of atmospheric pollution can be reduced. However, the thermal stability of groundwater will have a certain negative impact. The conclusion of this paper can be used as a reference for the application of ground-source heat pump technology in various regions, which can guide the healthy development of ground-source heat pump and promote the rational utilization of renewable energy according to local conditions. At the same time, it also has certain reference value for the reasonable design of ground source heat pump system in actual engineering.
