【摘要】：目前,由于高大空間建筑在冬季供暖時(shí),室內(nèi)氣流組織異常復(fù)雜,熱空氣由于熱浮力影響上浮,極易出現(xiàn)上熱下冷的溫度分層現(xiàn)象,這是對(duì)供暖工況極為不利的,而且采用不同的供暖末端方式,產(chǎn)生室內(nèi)溫度分層的效果也不盡相同,這也對(duì)暖通設(shè)計(jì)工程師提出了更高的要求。目前沒有統(tǒng)一的行業(yè)規(guī)范規(guī)定高大空間建筑冬季供暖工況的耗熱量計(jì)算方法,只是在原有的傳統(tǒng)耗熱量計(jì)算方法上進(jìn)行高度附加、風(fēng)力附加以及朝向附加修正。對(duì)高大空間建筑來講,區(qū)別于普通建筑冬季供暖的最大一點(diǎn)是其溫度分層特別明顯�？紤]到高大空間建筑的功能用途在社會(huì)生活上出現(xiàn)的頻率,本課題選擇了工業(yè)建筑和公共建筑作為高大空間建筑的研究對(duì)象;因嚴(yán)寒地區(qū)和寒冷地區(qū)建筑的圍護(hù)結(jié)構(gòu)的節(jié)能性要求不一樣,本課題選擇了嚴(yán)寒地區(qū)的哈爾濱市和寒冷地區(qū)的北京市和鄭州市作為地方性的典型城市;依據(jù)目前市場(chǎng)上常用的供暖方式,本課題選擇了散熱器供暖、低溫地板輻射供暖、燃?xì)饧t外輻射供暖3種供暖末端方式。為了研究不同供暖末端方式的高大空間建筑的耗熱量情況,本文先用傳統(tǒng)耗熱量計(jì)算方法計(jì)算了各地區(qū)不同類型高大空間建筑的不同供暖末端方式的供暖耗熱量情況。通過CFD數(shù)值模擬手段對(duì)18種工況進(jìn)行仿真計(jì)算,對(duì)比供暖模擬耗熱量和理論計(jì)算耗熱量的差值,通過對(duì)溫度場(chǎng)的不均勻度評(píng)價(jià),表明現(xiàn)有的耗熱量計(jì)算方法并不完全適合于高大空間建筑的供暖耗熱量計(jì)算。本文研究發(fā)現(xiàn)高大空間建筑的供暖耗熱量是和其供暖末端方式相關(guān)的,而且高度附加耗熱量的選擇對(duì)高大空間建筑供暖設(shè)計(jì)關(guān)重要的作用。此外,同一地區(qū),不同建筑類型的高大空間建筑對(duì)不同供暖末端方式的耗熱量計(jì)算有較大影響;同一建筑類型,不同氣候分區(qū)的高大空間建筑也對(duì)不同供暖末端方式的耗熱量計(jì)算有重要影響。
[Abstract]:At present, because the indoor airflow organization is very complicated when the large space buildings are heating in winter, the hot air is floating because of the influence of thermal buoyancy, so it is easy to appear the phenomenon of temperature stratification of upper heat and lower cooling, which is extremely disadvantageous to the heating condition. Moreover, the effect of indoor temperature stratification is different with different heating terminal methods, which puts forward higher requirements for HVAC design engineers. At present, there is no uniform industry standard to calculate the heat consumption of large space buildings in winter. It is only to carry on the height addition, the wind force addition and the orientation additional correction in the original traditional heat consumption calculation method. For large space buildings, the biggest difference from ordinary buildings in winter heating is that the temperature stratification is particularly obvious. Considering the frequency of the function use of the tall space building in the social life, this topic chooses the industrial building and the public building as the research object of the tall space building; Because of the different energy saving requirements of the building envelope structure in the cold area and the cold area, this subject chooses Harbin city in the cold area and Beijing and Zhengzhou city in the cold area as the typical local cities; According to the heating methods commonly used in the market at present, three kinds of end heating methods are selected: radiator heating, low temperature floor radiation heating and gas infrared radiation heating. In order to study the heat consumption of tall space buildings with different heating end ways, the heat consumption of different types of large space buildings in different regions is calculated by the traditional heat consumption calculation method. By means of CFD numerical simulation, 18 working conditions are simulated and calculated. The difference of heat consumption between heating simulation and theoretical calculation is compared, and the uneven degree of temperature field is evaluated. The results show that the existing heat consumption calculation method is not suitable for the heat consumption calculation of large space buildings. In this paper, it is found that the heating heat consumption of tall space buildings is related to its heating terminal mode, and the choice of high additional heat consumption plays an important role in the heating design of tall space buildings. In addition, in the same area, the large space buildings of different building types have great influence on the calculation of heat consumption of different heating end ways. The same type of buildings and large space buildings with different climatic zones also have an important influence on the calculation of heat consumption in different heating terminal modes.
