【摘要】:近年來環(huán)境問題在我國越來越突出,因此節(jié)能環(huán)保技術(shù)越來越受到重視。地源熱泵系統(tǒng)是利用淺層地能進(jìn)行制冷與供熱的節(jié)能環(huán)保技術(shù),因此有利推動了地源熱泵系統(tǒng)在市場的推廣。隨著地源熱泵系統(tǒng)的推廣,地下熱積累問題也凸顯出來,在很大程度上限制地源熱泵系統(tǒng)高效穩(wěn)定運(yùn)行。本文以安徽地區(qū)為例,建立典型的夏熱冬冷建筑模型,模擬某建筑運(yùn)行50年后的地下土壤變化,以便為設(shè)計值提高相關(guān)參考,為地源熱泵系統(tǒng)優(yōu)化運(yùn)行方式提供指導(dǎo)。 本文首先選取安徽地區(qū)某辦公建筑為例,運(yùn)用Dest-C模擬建筑全年逐時冷熱負(fù)荷。然后運(yùn)用模擬軟件模擬運(yùn)行50年后的地源熱泵地下土壤溫度變化情況,根據(jù)模擬結(jié)果分析并優(yōu)化建筑負(fù)荷結(jié)構(gòu),,從而使得地源熱泵系統(tǒng)可以長期穩(wěn)定運(yùn)行。并分析不同建筑冷熱負(fù)荷不平衡率,找出適合該地區(qū)的辦公樓類建筑的最小冷熱負(fù)荷不平衡率,為設(shè)計地源熱泵系統(tǒng)提供參考。再根據(jù)模擬分析結(jié)果,提供最優(yōu)的輔助措施,來平衡建筑冷熱負(fù)荷不平衡率。 采用地源熱泵系統(tǒng)模擬預(yù)測土壤溫度與采取相應(yīng)的土壤溫度穩(wěn)定措施,可以有效的優(yōu)化建筑設(shè)計方案和運(yùn)行方案,從而達(dá)到地源熱泵處于長期穩(wěn)定的運(yùn)行狀況,進(jìn)而體現(xiàn)地源熱泵系統(tǒng)的節(jié)能環(huán)保特點(diǎn)。
[Abstract]:In recent years, environmental problems have become more and more prominent in China, so energy conservation and environmental protection technology has been paid more and more attention. Ground-source heat pump system is an energy saving and environmental protection technology which uses shallow ground energy to refrigerate and heat supply, so it is advantageous to promote the promotion of ground-source heat pump system in the market. With the popularization of ground-source heat pump system, the problem of underground heat pump accumulation is also prominent, which limits the efficient and stable operation of ground-source heat pump system to a great extent. Taking Anhui as an example, a typical building model of hot summer and cold winter is set up to simulate the underground soil change after 50 years of operation of a building, in order to improve the relevant reference for the design value and to provide guidance for optimizing the operation mode of ground-source heat pump system. In this paper, an office building in Anhui Province is selected as an example, and Dest-C is used to simulate the hourly heat and cold load of the building. Then the ground-source heat pump (GSHP) ground temperature changes after 50 years of operation are simulated by using simulation software. According to the simulation results, the structure of building load is analyzed and optimized, so that the GSHP system can operate steadily for a long time. The unbalance rate of cooling and heat load of different buildings is analyzed, and the minimum unbalance rate of heat and cold load of office buildings suitable for this area is found out, which provides a reference for the design of ground-source heat pump system. According to the results of simulation analysis, the optimal auxiliary measures are provided to balance the unbalanced rate of cooling and heat load. The ground-source heat pump system can be used to simulate and predict the soil temperature and take the corresponding soil temperature stabilization measures, which can effectively optimize the architectural design and operation scheme, so that the ground source heat pump is in a long-term stable operation. And then reflect the energy conservation and environmental protection characteristics of ground source heat pump system.
