【摘要】：眾所周知,工業(yè)建筑與民用建筑在使用功能上具有很大的差異,兩者在建筑節(jié)能方面亦應(yīng)具有不同的設(shè)計(jì)要求。不同類型的工業(yè)建筑依據(jù)生產(chǎn)工藝所需要,其室內(nèi)環(huán)境的要求也各有不同。這種復(fù)雜的情況使得國(guó)家并未出臺(tái)相應(yīng)的工業(yè)建筑節(jié)能標(biāo)準(zhǔn),在實(shí)際的工業(yè)建筑設(shè)計(jì)中,只能參照民用建筑規(guī)范來(lái)進(jìn)行節(jié)能設(shè)計(jì),使得建筑節(jié)能措施的廣泛應(yīng)用產(chǎn)生一定的困難。在學(xué)界,有大量關(guān)于工業(yè)建筑節(jié)能的研究,其內(nèi)容還不夠深入,對(duì)工業(yè)建筑節(jié)能措施的設(shè)計(jì)不具有針對(duì)性的實(shí)踐意義。隨著人們環(huán)保意識(shí)的提升,能源消耗問(wèn)題被國(guó)家提上日程,那么對(duì)于工業(yè)廠房的節(jié)能研究已經(jīng)刻不容緩。隨著經(jīng)濟(jì)的快速發(fā)展,人民生活水平的提升,潔凈廠房所生產(chǎn)的產(chǎn)品如電子、食品、醫(yī)療用品等逐漸成為生活的必需品。而潔凈廠房因其特殊的生產(chǎn)環(huán)境,需要通過(guò)暖通空調(diào)系統(tǒng)全年不間斷的持續(xù)工作來(lái)控制室內(nèi)的溫濕度變化以及空氣潔凈度等級(jí)的維持,并且在廠房設(shè)計(jì)時(shí)沒(méi)有注重節(jié)能設(shè)計(jì),使得潔凈廠房產(chǎn)生了大量的能源消耗。尤其對(duì)于我國(guó)嚴(yán)寒地區(qū)而言,惡劣的室外環(huán)境,使得建筑能源的消耗量進(jìn)一步增加。所以說(shuō),將嚴(yán)寒地區(qū)潔凈廠房的節(jié)能設(shè)計(jì)作為研究對(duì)象是很有必要的。首先,通過(guò)前期調(diào)研和文獻(xiàn)收集,梳理出潔凈廠房的發(fā)展脈絡(luò)并且對(duì)當(dāng)代的潔凈廠房分類有一個(gè)清晰的認(rèn)識(shí)。其次,在嚴(yán)寒地區(qū)(新疆石河子市)挑選出有特點(diǎn)的某工業(yè)潔凈廠房進(jìn)行細(xì)致調(diào)研。對(duì)每個(gè)工段所需要的生產(chǎn)條件、人員活動(dòng)、設(shè)備熱源、暖通空調(diào)系統(tǒng)等情況進(jìn)行細(xì)致的記錄。發(fā)現(xiàn)對(duì)于潔凈廠房而言,不同于其他工業(yè)建筑,該類型的建筑暖通空調(diào)設(shè)備需全年不間斷運(yùn)行。并且在廠房制面車間發(fā)現(xiàn)停工時(shí)存在嚴(yán)重的結(jié)露問(wèn)題。然后依據(jù)工廠的現(xiàn)場(chǎng)情況,推測(cè)產(chǎn)生這種問(wèn)題的原因,隨后對(duì)該工段進(jìn)行有針對(duì)性的溫濕度測(cè)試,然后分析該工段測(cè)試數(shù)據(jù),得出廠房結(jié)露的原因是由于廠房的生產(chǎn)工藝造成局部區(qū)域溫濕度過(guò)高,停工后室內(nèi)熱源減少,溫度降低,空氣達(dá)到露點(diǎn)溫度而產(chǎn)生的。為了對(duì)廠房整體的熱環(huán)境情況有一個(gè)全面的了解,再將儀器分別設(shè)置在工廠的不同工段內(nèi),進(jìn)行有針對(duì)性的冬夏兩季測(cè)試。將測(cè)試結(jié)果進(jìn)行分析和統(tǒng)計(jì),歸納出測(cè)試廠房各車間的室內(nèi)溫濕度變化規(guī)律,發(fā)現(xiàn)同一工廠內(nèi)不同生產(chǎn)階段,由于生產(chǎn)工藝的影響,在車間內(nèi)會(huì)形成不同的室內(nèi)環(huán)境。與此同時(shí),發(fā)現(xiàn)冬季人身潔凈區(qū)、包裝車間以及混面車間的溫度均未達(dá)到工藝所需的生產(chǎn)溫度。另外通過(guò)分析數(shù)據(jù)發(fā)現(xiàn)窗戶是廠房的節(jié)能的薄弱點(diǎn)。再次,通過(guò)使用計(jì)算機(jī)模擬技術(shù),采用控制變量法,在滿足生產(chǎn)工藝溫濕度要求的情況下,依次分析不同保溫層厚度、墻體構(gòu)造、屋面構(gòu)造、透明圍護(hù)結(jié)構(gòu)的能耗情況,同時(shí)結(jié)合經(jīng)濟(jì)學(xué)中回收期的思想,通過(guò)比較得出,對(duì)于嚴(yán)寒地區(qū)既有潔凈廠房改造而言,屋面采用120mm的EPS保溫板經(jīng)濟(jì)效果最好;墻面采用90mm的XPS保溫板經(jīng)濟(jì)性最好;窗戶采用低輻射中空l(shuí)ow-E雙玻窗經(jīng)濟(jì)性最好的結(jié)論。最后,綜合實(shí)地調(diào)研與模擬結(jié)果,依據(jù)工業(yè)廠房建筑能耗構(gòu)成的七個(gè)方面,提出針對(duì)嚴(yán)寒地區(qū)潔凈廠房在建筑形體及平面布置方面、圍護(hù)結(jié)構(gòu)方面、采光和遮陽(yáng)方面、暖通空調(diào)方面以及再生能源利用方面的節(jié)能設(shè)計(jì)策略。工業(yè)廠房建筑其建筑能源利用率的提升是依靠建筑節(jié)能設(shè)計(jì)實(shí)現(xiàn)的。如果在工業(yè)建筑中生搬硬套民用建筑中一些成熟的節(jié)能設(shè)計(jì)策略,是不能夠有效的降低工業(yè)建筑能耗的。文章中通過(guò)討論嚴(yán)寒地區(qū)潔凈廠房的存在節(jié)能問(wèn)題,提出建筑節(jié)能設(shè)計(jì)中的設(shè)計(jì)策略,希望能夠?yàn)榻窈蟮膰?yán)寒地區(qū)潔凈廠房的節(jié)能設(shè)計(jì)提供一定的科學(xué)理論依據(jù)。
[Abstract]:It is well known that industrial buildings and civil buildings have great difference in using function, and they should also have different design requirements in building energy saving. Different types of industrial buildings require different indoor environments depending on the production process. This kind of complicated situation makes the country do not adopt the corresponding standard of industrial building energy-saving, in the actual industrial building design, can only reference the civil building standard to carry on the energy-saving design, make the building energy-saving measure widely apply to produce certain difficulty. In the academic circles, there is a lot of research on building energy-saving in industry, its contents are not deep enough, and the design of building energy-saving measures is not practical significance. With the promotion of people's awareness of environmental protection, the problem of energy consumption is put up by the country, so it is urgent to study the energy-saving of industrial buildings. With the rapid development of economy, the improvement of people's living standards, the products produced by clean plants, such as electronics, food, medical supplies and so on, gradually become necessities of life. As a result of its special production environment, the clean house needs to continuously work continuously throughout the year through the HVAC system to control the indoor temperature and humidity changes as well as the maintenance of the air cleanliness level, and do not pay attention to the energy-saving design at the time of the plant design. so that a large amount of energy consumption is generated in the clean factory building. Especially for severe cold areas in our country, the poor outdoor environment makes the consumption of construction energy further increase. Therefore, it is necessary to design the energy-saving design of clean factory buildings in severe cold areas as research objects. First, through preliminary research and literature collection, the development vein of clean factory building is sorted out and a clear understanding is given to the classification of modern clean factory buildings. Secondly, in severe cold areas (Shihezi city, Xinjiang), a special industrial clean factory has been selected for detailed investigation. Detailed records shall be made for production conditions, personnel activities, equipment heat sources, HVAC systems, etc. required for each section. It is found that for clean plants, unlike other industrial buildings, this type of building HVAC equipment needs uninterrupted operation throughout the year. and there is a serious problem of condensation during shutdown in the workshop manufacturing workshop. Then, according to the site situation of the plant, the reason of this problem is estimated, and then a targeted temperature and humidity test is carried out on the workshop section, and then the test data of the workshop section is analyzed. The reason of the factory building condensation is that the temperature and humidity of the local area are too high due to the production process of the factory building. After the shutdown, the indoor heat source is reduced, the temperature is reduced, and the air reaches the dew point temperature. In order to have a comprehensive understanding of the thermal environment of the whole plant, the instruments are respectively arranged in different sections of the factory to carry out targeted winter and summer test. According to the analysis and statistics of the test results, the change rule of indoor temperature and humidity in each workshop of the test workshop is summarized, and the different production stages in the same plant are found, and different indoor environments can be formed in the workshop due to the influence of the production process. At the same time, it was found that the temperature of the clean area, the packaging workshop and the mixing workshop in winter did not reach the production temperature required for the process. In addition, the analysis of the data reveals that the window is the energy-saving weak point of the factory building. once again, by using the computer simulation technology, under the condition that the temperature and humidity requirements of the production process are met, the thickness of the heat insulation layer, the wall structure, the roof structure and the energy consumption of the transparent envelope are sequentially analyzed, and meanwhile, the idea of the payback period in economics is combined, It is concluded that the economic effect of 120mm EPS insulation board is the best for the renovation of the existing clean workshop in severe cold areas; the economic performance of the 90mm XPS insulation board is the best; the window adopts the conclusion that the low radiation hollow low-E double glass window has the best economical efficiency. Finally, on the basis of seven aspects of building energy consumption of industrial buildings, according to seven aspects of building energy consumption of industrial buildings, this paper puts forward the aspects of building structure and floor layout, lighting and sun-shading for clean workshop in severe cold areas. Energy-saving design strategy for HVAC and renewable energy utilization. The building energy utilization ratio of industrial plant building is realized by building energy-saving design. If some mature energy-saving design strategies are used in industrial buildings, the energy consumption of industrial buildings can not be effectively reduced. In this paper, the design strategy of building energy-saving design is put forward by discussing the energy-saving problem of clean workshop in severe cold area, and it is hoped that it can provide some scientific theoretical basis for the energy-saving design of clean workshop in the future.
