摘要：作者：嚴慶翱; 金寧 關(guān)鍵詞：暖通空調(diào)論文,室內(nèi)機,送風參數(shù) 【中文摘要】 對天花板內(nèi)藏直吹式空調(diào)器測試房間為模型,應(yīng)用AirPak軟件在制冷運行時不同送風參數(shù)下的流場和溫度場進行了數(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)作為氣流組織評價指標。結(jié)果表明:相同風量下,送風角度越小,室內(nèi)溫度和速度越均勻,能量利用越好;相同送風角度下,風量越大,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; 送風參數(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
