【摘要】：地埋管地源熱泵系統(tǒng)作為地源熱泵空調(diào)技術(shù)中的主導(dǎo)形式,有著非常好的節(jié)能和環(huán)保效益,并且在一定程度上避免了諸如地下水地源熱泵系統(tǒng)對(duì)地下水資源的負(fù)面影響,因此在我國得到了廣泛的研究和應(yīng)用。但是地埋管地源熱泵系統(tǒng)初投資很高,系統(tǒng)較為龐大,對(duì)場(chǎng)地的要求也較高,對(duì)于實(shí)際的工程來說,選擇地埋管地源熱泵系統(tǒng)到底節(jié)約多少常規(guī)能源,實(shí)現(xiàn)多少二氧化碳減排量等問題都是需要分析的,如果盲目采用,不僅達(dá)不到理想的運(yùn)行效果,甚至不能夠正常運(yùn)行,對(duì)能源和資源都是嚴(yán)重的浪費(fèi)。因此,有必要綜合歸納該系統(tǒng)的節(jié)能效益、環(huán)保效益、經(jīng)濟(jì)效益和技術(shù)效益,建立一套比較完善的地埋管地源熱泵系統(tǒng)性能評(píng)價(jià)體系。這正是本文研究的背景和出發(fā)點(diǎn)。 本文從地埋管地源熱泵系統(tǒng)的運(yùn)行原理、特點(diǎn)和實(shí)際應(yīng)用入手,將地源熱泵系統(tǒng)的主要影響因素歸納并建立綜合評(píng)價(jià)指標(biāo)的遞階層次結(jié)構(gòu),通過層次分析法,得出各指標(biāo)的權(quán)重。并利用SPSS軟件基于多元線性回歸分析的原理,建立某些已知分指標(biāo)與其對(duì)應(yīng)的二級(jí)指標(biāo)之間的預(yù)測(cè)公式。通過層次分析法與多元線性回歸分析相結(jié)合,最后建立目標(biāo)層即地埋管地源熱泵系統(tǒng)綜合性能評(píng)價(jià)指標(biāo)的預(yù)報(bào)方程。通過二級(jí)指標(biāo)層的各個(gè)因子的實(shí)際值,預(yù)測(cè)得到目標(biāo)層即地源熱泵系統(tǒng)綜合評(píng)價(jià)指標(biāo)。本文通過總結(jié)地源熱泵系統(tǒng)相關(guān)的規(guī)范標(biāo)準(zhǔn),建立了地埋管地源熱泵系統(tǒng)性能評(píng)價(jià)指標(biāo)得分體系,并通過目標(biāo)層的預(yù)測(cè)公式最終得到了地源熱泵系統(tǒng)綜合性能評(píng)價(jià)指標(biāo)分?jǐn)?shù)。 通過對(duì)具體實(shí)際工程的評(píng)價(jià),本文得出地埋管地源熱泵系統(tǒng)在節(jié)能方面效果顯著。經(jīng)濟(jì)方面,初投資尤其是鉆孔費(fèi)用較大。環(huán)保方面,可以有效提高溫室氣體減排量、粉塵減排量等,減少對(duì)大氣的污染程度。但是對(duì)地下水的熱穩(wěn)定會(huì)產(chǎn)生一定的負(fù)面影響。 本課題的研究結(jié)論對(duì)各地區(qū)開展地源熱泵技術(shù)的應(yīng)用有所參考,可以引導(dǎo)地源熱泵的健康發(fā)展,推動(dòng)可再生能源的因地制宜、合理利用。同時(shí)對(duì)實(shí)際工程中地源熱泵系統(tǒng)的合理設(shè)計(jì)也有一定的參考價(jià)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.
