摘要：作者：吳梅艷; 歐陽金城; 劉 關(guān)鍵詞：暖通空調(diào)論文,工位空調(diào),水平射流 【摘要】 實(shí)驗(yàn)研究了水平射流桌面式工位空調(diào)的送風(fēng)特性及其影響因素。研究結(jié)果表明,風(fēng)口高度位置存在吹風(fēng)風(fēng)險(xiǎn)。要保證人員的熱舒適性,必須合理設(shè)計(jì)送風(fēng)參數(shù),選擇合適的風(fēng)口尺寸和送風(fēng)距離。對于圓形送風(fēng)口,保證新風(fēng)量同時(shí)不產(chǎn)生冷吹風(fēng)感的風(fēng)口直徑應(yīng)不小于12cm,送風(fēng)距離以50～80cm為宜;增大送風(fēng)百葉的夾角,能在垂直方向有效分散送風(fēng),但夾角過大,不利于新風(fēng)的有效利用。 【Abstract】 The air supply characteristics of a desktop task conditioning system with the horizontal jets and their influencing factors are studied experimentally.The results show that there is a draught risk at the height of air supply opening.In order to ensure the thermal comfort,the air supply parameters should be selected reasonably,as well as the opening size and the distance of air supply.For the round air supply outlet the diameter should not be less than 12cm and the appropriate air supply distance is about 50 to 80 centimeter.The draught risk can be reduced by increasing the angle between the air supply louvres,but the fresh air can not be effectively used when the angle is too large. 【關(guān)鍵詞】 工位空調(diào); 水平射流; 吹風(fēng)感【Key words】 Task air conditioning; Level jet; Draught sensation
