【摘要】：陜南跨越夏熱冬冷地區(qū)和寒冷地區(qū)兩個氣候區(qū)。夏熱冬冷地區(qū)屬于國家規(guī)定的非采暖區(qū)。但調研得知,隨著人們對室內熱環(huán)境要求的提高,漢中市、安康市近年來越來越多的住宅開始冬季采暖,建筑能耗也隨之大幅度增加。因此,如何改善漢中市、安康市城鎮(zhèn)住宅建筑的冬季室內熱環(huán)境狀況,又能降低建筑能耗是急需研究的課題。陜南地區(qū)中的商洛市屬于寒冷地區(qū),但從地域性資源條件分析,該地區(qū)和以西安市為代表的關中寒冷地區(qū)有較大的區(qū)別,而與同處于陜南地區(qū)的漢中市、安康市更為相似,但目前對陜西省以及西北地區(qū)建筑節(jié)能的研究以西安市為代表的寒冷地區(qū)研究較多,對商洛市的研究很少。因此,本研究按行政區(qū)劃對陜南地區(qū)的漢中市、安康市、商洛市的城鎮(zhèn)采暖住宅進行節(jié)能設計研究。本研究對漢中市、安康市、商洛市的城鎮(zhèn)住宅的建筑現(xiàn)狀、采暖現(xiàn)狀、圍護結構的構造及熱工性能現(xiàn)狀、冬季室內外熱環(huán)境現(xiàn)狀進行了大量實地調研與測試。在調研、測試、分析的基礎上,總結出該地區(qū)城鎮(zhèn)采暖住宅存在的節(jié)能問題。針對該地區(qū)城鎮(zhèn)采暖住宅建筑節(jié)能的實際狀況以及存在的節(jié)能問題,著重從城鎮(zhèn)采暖住宅的規(guī)劃節(jié)能設計、圍護結構的節(jié)能設計、采暖節(jié)能設計等方面進行地域針對性的住宅建筑節(jié)能設計研究。主要研究成果如下:(1)通過傳熱系數(shù)、熱惰性指標的計算,結合陜南地區(qū)漢中市、安康市頁巖空心磚和加氣混凝土砌塊的規(guī)格尺寸,得出了滿足陜西省《居住建筑節(jié)能設計標準》的外墻使用自保溫材料的墻體的熱工性能及適當厚度。模擬研究表明在漢中市、安康市同厚度的頁巖空心磚自保溫墻體的節(jié)能效果優(yōu)于加氣混凝土砌塊自保溫墻體。該研究同時也表明,自保溫墻體在夏熱冬冷地區(qū)具有技術適宜性。(2)對比漢中市、安康市外墻內、外保溫的研究結果表明:外墻外保溫的節(jié)能效果優(yōu)于外墻內保溫,在外墻保溫中應優(yōu)先選擇外保溫;模擬研究還表明漢中市、安康市雖然采用間歇式、分空間采暖,但住宅建筑的內墻不適合設保溫層,內墻增設保溫層后,反而會增加建筑的總能耗,不利于節(jié)能。(3)通過對陜南地區(qū)各種采暖方式的綜合比較以及對水源熱泵系統(tǒng)示范項目的節(jié)能技術分析研究表明:陜南地區(qū)冬季用水源熱泵地板輻射采暖具有很強的技術經濟性。本研究還運用建筑環(huán)境設計模擬分析軟件對陜南地區(qū)漢中市、安康市的城鎮(zhèn)采暖住宅在選用不同的外墻保溫材料及不同厚度時的建筑能耗進行了模擬計算,得出了陜南地區(qū)漢中市、安康市的八種外墻保溫材料的保溫隔熱性能及每種保溫材料的適宜厚度。研究成果對陜南地區(qū)城鎮(zhèn)采暖住宅的節(jié)能設計提供理論依據(jù)及實踐指導作用,也為設計人員在其他類似氣候區(qū)進行住宅節(jié)能設計提供借鑒和參考。
[Abstract]:Southern Shaanxi spans the hot summer and cold winter regions and the cold regions. The hot summer and cold winter areas belong to the non-heating areas prescribed by the state. However, the investigation shows that with the improvement of people's requirements for the indoor thermal environment, Hanzhong City, In recent years, more and more residential buildings in Ankang City have started heating in winter, and the building energy consumption has also increased by a large margin. Therefore, how to improve the indoor thermal environment of residential buildings in Hanzhong and Ankang cities in winter, It is urgent to study the problem of reducing building energy consumption. Shangluo city in southern Shaanxi belongs to cold area, but from the analysis of regional resource conditions, it is quite different from Guanzhong cold area represented by Xi'an. Compared with Hanzhong city in southern Shaanxi, Ankang city is more similar to Hanzhong city, but there are more researches on building energy conservation in Shaanxi province and northwest region than in Shangluo city, which are represented by Xi'an city. According to the administrative division, this paper studies the energy saving design of urban heating houses in Hanzhong, Ankang and Shangluo in southern Shaanxi. This research is about the present architectural situation and heating status of urban houses in Hanzhong, Ankang and Shangluo. On the basis of investigation, test and analysis, a large number of field investigations and tests have been carried out on the construction and thermal performance of the enclosure structure and the present situation of indoor and outdoor thermal environment in winter. This paper summarizes the problems of energy saving in urban heating houses in this area. In view of the actual situation of energy-saving of urban heating residential buildings in this area and the existing problems of energy saving, this paper focuses on the energy saving design of urban heating houses and the energy saving design of enclosure structures. The main research results are as follows: (1) through the calculation of heat transfer coefficient and thermal inertia index, combined with Hanzhong City in South Shaanxi region, The specification and size of shale hollow brick and aerated concrete block in Ankang City are obtained. The thermal performance and appropriate thickness of wall with self-insulating material used in exterior wall of Shaanxi Province are obtained. The simulation study shows that in Hanzhong City, The energy saving effect of shale hollow brick self-insulating wall with the same thickness in Ankang City is better than that of aerated concrete block self-insulating wall. The study also shows that the self-insulating wall has technical suitability in hot summer and cold winter area compared with Hanzhong City. The results show that the energy saving effect of exterior wall thermal insulation is better than that of external wall insulation, and the external insulation should be selected first in the exterior wall insulation. The simulation study also shows that Hanzhong City, Ankang City, although using intermittent type, Space heating, but the inner wall of residential buildings is not suitable for the installation of insulation, the inner wall will increase the total energy consumption of the building after the addition of insulation layer. Through the comprehensive comparison of various heating modes in southern Shaanxi and the analysis of energy-saving technology for demonstration project of water source heat pump system, it is shown that the radiant floor heating of water source heat pump in southern Shaanxi in winter is very strong. This study also uses the architectural environment design simulation analysis software to the Hanzhong city in the south of Shaanxi province, The building energy consumption of urban heating houses in Ankang City is simulated and calculated when different exterior wall insulation materials and thickness are selected, and the Hanzhong City in South Shaanxi region is obtained. The thermal insulation properties of eight kinds of exterior wall insulation materials and the suitable thickness of each kind of insulation materials in Ankang City. The research results provide theoretical basis and practical guidance for the energy saving design of urban heating houses in southern Shaanxi. Also for designers in other similar climate areas for residential energy-saving design to provide reference and reference.
