摘要：作者：嚴(yán)慶翱; 金寧 關(guān)鍵詞：暖通空調(diào)論文,室內(nèi)機(jī),送風(fēng)參數(shù) 【中文摘要】 對(duì)天花板內(nèi)藏直吹式空調(diào)器測(cè)試房間為模型,應(yīng)用AirPak軟件在制冷運(yùn)行時(shí)不同送風(fēng)參數(shù)下的流場(chǎng)和溫度場(chǎng)進(jìn)行了數(shù)值模擬。并以溫度不均勻系數(shù)、速度不均勻系數(shù)和能量利用系數(shù)作為氣流組織評(píng)價(jià)指標(biāo)。結(jié)果表明:相同風(fēng)量下,送風(fēng)角度越小,室內(nèi)溫度和速度越均勻,能量利用越好;相同送風(fēng)角度下,風(fēng)量越大,室內(nèi)溫度和速度越均勻,能量利用越好?！居⑽恼?The paper takes ceiling containing blowing straight type indoor unit as research object, numerical simulation through AirPak software was carried out to study the distribution characteristics of airflow temperature field under different air supply condition refrigeration. It takes the temperature nonuniformity coefficient, speed nonuniformity coefficient, and energy utilization coefficient as the air current organization evaluating indicator. The result shows: the small the blast angle, the more uniformity of indoor temperature and speed, the better energy utilization under the same air volume; the large the air volume, the more uniformity of indoor temperature and speed, the better energy utilization under the same blast angle. 【中文關(guān)鍵詞】 室內(nèi)機(jī); 送風(fēng)參數(shù); 氣流組織; 數(shù)值模擬【英文關(guān)鍵詞】 Indoor unit; Supply parameters; Air current distribution; Numerical simulatio
