【摘要】：由于城市建設的飛速發(fā)展，對新型墻體材料的運用越來越多，也就帶來建筑節(jié)能工程設計發(fā)展，同時也涌現(xiàn)出了許多建筑能耗問題。作為工程設計的一個重要部分，建筑節(jié)能設計涉及的技術領域非常廣泛，既包括墻體材料方面的課題，更有建筑能耗模擬研究的課題。本文通過閱讀大量參考文獻，調(diào)查分析四種墻體材料的生產(chǎn)能耗和物耗，運用ANSYS軟件對墻體的節(jié)能性能進行分析。并以監(jiān)利市監(jiān)利·銀湖城項目中一棟高層居民建筑為模型，運用理論分析和數(shù)值模擬分析方法，比較了四種外墻在使用過程中的夏季制冷冬季采暖的能耗。主要工作和結(jié)論如下： （1）對四種新型墻體材料的生產(chǎn)原料以及生產(chǎn)工藝進行分析，對它們在生產(chǎn)過程中的物耗和能耗進行測算。數(shù)據(jù)分析結(jié)果，生產(chǎn)單位體積泡沫混凝土的能耗、物耗最小，近似為350Kw·h、水泥323kg、粉煤灰54kg，蒸壓砂加氣混凝土砌塊的是600Kw·h，蒸壓加氣混凝土砌塊的是650Kw·h，，蒸壓灰砂磚的是510Kw·h。 （2）為了比較這四種墻體材料在節(jié)能性能上的優(yōu)劣，運用ANSYS軟件進行有限元熱分析，模擬在室外溫度36度，室內(nèi)溫度25度的情況下，計算墻體各個節(jié)點的溫度。得出結(jié)論，蒸壓加氣混凝土砌塊內(nèi)溫度分布均勻，隔熱性能較好。蒸壓砂加氣混凝土砌塊與泡沫混凝土內(nèi)溫度分布均勻，溫度下降較快且相似，隔熱性能更好。蒸壓灰砂磚內(nèi)部溫度較高，但在保溫砂漿層溫度下降較快，影響保溫砂漿使用壽命； （3）本文對節(jié)能設計原理進行分析，掌握對節(jié)能設計影響的因素，通過能耗計算結(jié)果，進行節(jié)能設計優(yōu)化。根據(jù)四個季節(jié)的氣候特點模擬，以及每天24小時溫度輻射等進行模擬。能耗計算得到的能耗數(shù)據(jù)，對建筑節(jié)能數(shù)據(jù)進行分析整理，掌握使用過程中不同墻材建筑的能耗量，并進行比較。得出結(jié)論，四種新型墻體材料全生命周期能耗總量最低的是由泡沫混凝土作為墻體的建筑，蒸壓砂加氣混凝土砌塊、蒸壓加氣混凝土砌塊、蒸壓灰砂磚，能耗量依次增高。蒸壓灰砂磚與加氣混凝土墻體相比較，可得只需要在生產(chǎn)中多投入些能耗，在使用過程中我們能夠得到高回報。
[Abstract]:With the rapid development of urban construction, more and more new wall materials have been used, which has brought about the development of building energy saving engineering design, and at the same time, a lot of building energy consumption problems have emerged, which is an important part of engineering design. The design of building energy conservation involves a wide range of technical fields, including the subject of wall materials and the subject of building energy consumption simulation. This paper, by reading a large number of references, investigates and analyzes the production energy consumption and material consumption of four kinds of wall materials. Using ANSYS software to analyze the energy saving performance of the wall, and taking a high-rise residential building in Jianli 路Yinhu City Project of Jianli City as a model, using theoretical analysis and numerical simulation analysis method. The energy consumption of four kinds of exterior walls in summer refrigeration and winter heating is compared. The main work and conclusions are as follows:. This paper analyzes the raw materials and production process of four new wall materials, and calculates the material consumption and energy consumption in the production process. The results show that the energy consumption per unit volume of foamed concrete is the smallest. About 350 KW 路h, 323kg cement, 54kg fly ash, 600kw 路h autoclaved sand aerated concrete block, 650Kw 路h autoclaved aerated concrete block, 510Kw 路h autoclaved lime sand brick. In order to compare the advantages and disadvantages of the four kinds of wall materials in energy saving performance, the finite element thermal analysis is carried out by using ANSYS software, and the temperature of each node of the wall is calculated under the condition of outdoor temperature of 36 degrees and indoor temperature of 25 degrees. The temperature distribution in autoclaved aerated concrete block is uniform, and the thermal insulation property is better. The temperature distribution of autoclaved sand aerated concrete block and foam concrete block is uniform, the temperature drop is faster and similar, the thermal insulation property is better, and the internal temperature of autoclaved lime sand brick is higher. However, the temperature of the insulating mortar layer decreases rapidly, which affects the service life of the insulating mortar. This paper analyzes the principle of energy saving design, grasps the factors that affect energy saving design, optimizes the energy saving design through the result of energy consumption calculation, and simulates the climate characteristics of four seasons. The energy consumption data obtained from the energy consumption calculation, the analysis and arrangement of the building energy saving data, the mastery of the energy consumption of different wall buildings in the process of use, and the comparison between them, are concluded. The lowest total energy consumption in the whole life cycle of the four new wall materials is the building with foam concrete as the wall, autoclaved sand aerated concrete block, autoclaved aerated concrete block, autoclaved lime sand brick, Compared with the aerated concrete wall, autoclaved lime-sand brick can only put in more energy consumption in production, and we can get a high return in the process of use.
