【摘要】：目的對公共建筑中庭冬季供暖空調(diào)系統(tǒng)導(dǎo)致的室內(nèi)溫度不均現(xiàn)狀進(jìn)行改造,以滿足人體舒適性,提高經(jīng)濟(jì)性.方法對沈陽地區(qū)某高校圖書館中庭冬季采用傳統(tǒng)空調(diào)供暖的氣流組織分布情況進(jìn)行研究,對實測結(jié)果與CFD模擬結(jié)果進(jìn)行對比,分析是否符合《公共建筑節(jié)能設(shè)計標(biāo)準(zhǔn)》,提出采用太陽墻技術(shù)并分析其可行性.結(jié)果通過對圖書館中庭進(jìn)行溫度場模擬發(fā)現(xiàn),中庭的垂直溫差達(dá)到5℃左右,當(dāng)前中庭內(nèi)溫度并不能達(dá)到設(shè)計溫度.采用太陽墻新風(fēng)系統(tǒng)+傳統(tǒng)空調(diào)采暖耦合作用能很好地解決中庭內(nèi)平均溫度偏低的問題,且可以保證室內(nèi)新風(fēng)量的供給.結(jié)論從中庭實測數(shù)據(jù)及CFD模擬出發(fā),使用太陽墻改造措施,有助于改進(jìn)和優(yōu)化采暖設(shè)計方案.
[Abstract]:Objective to improve the indoor temperature imbalance caused by atrium heating and air conditioning system in public buildings in order to satisfy human comfort and improve economy. Methods the distribution of air flow in the atrium of a university library in Shenyang in winter using traditional air conditioning heating was studied. The measured results were compared with the results of CFD simulation, and the results were analyzed whether it was in accordance with the Standard for Energy Saving Design of Public buildings. The solar wall technology is proposed and its feasibility is analyzed. Results by simulating the temperature field of the library atrium, it was found that the vertical temperature difference of the atrium was about 5 鈩，
