【摘要】：本文以焓差實(shí)驗(yàn)室為平臺,以住宅建筑凹槽內(nèi)的兩臺某型號分體式空調(diào)室外機(jī)的安裝條件為研究對象,研究三種室外機(jī)安裝條件對周圍熱環(huán)境、空調(diào)器EER和凹槽面積的影響。凹槽內(nèi)室外機(jī)的三種安裝條件分別為同一平面相互垂直安裝(兩室外機(jī)在同一高度,室外機(jī)長度延長線互相垂直相交)、同一平面左右水平安裝(兩室外機(jī)在同一高度,室外機(jī)長度延長線共線)及沿外墻上下垂直安裝(不同高度,室外機(jī)高度延長線共線)。實(shí)驗(yàn)結(jié)果表明:該型號兩臺室外機(jī)同一平面垂直安裝時(shí),建議水平間距(平行于外墻)d_1≥650 mm,小于此間距時(shí),距百葉較遠(yuǎn)的室外機(jī)運(yùn)行環(huán)境惡劣,回風(fēng)溫度高于正常運(yùn)行溫度45℃;垂直間距(垂直于外墻)d_2選擇300 mm左右,繼續(xù)增大則回風(fēng)溫度上升;當(dāng)凹槽內(nèi)兩臺室外機(jī)間不具備水平安裝條件,但滿足水平、垂直間距大于650 mm×300 mm空間要求時(shí),建議采用平面垂直安裝方式。水平安裝時(shí),回風(fēng)效果較好,但考慮凹槽占用面積大,且水平間距d_170 mm后,回風(fēng)溫度和EER都趨于平穩(wěn),故最佳間距為70 mm。上下垂直安裝時(shí),凹槽占地面積小于水平安裝方式和平面垂直安裝方式,回風(fēng)效果明顯優(yōu)于平面垂直安裝方式,最低回風(fēng)溫度甚至低于水平安裝方式,最佳間距為150 mm。
[Abstract]:In this paper, the enthalpy difference laboratory is taken as the platform, and the installation conditions of two separate type outdoor air conditioners in the grooves of residential buildings are taken as the research object, and the thermal environment of the surrounding environment is studied under the installation conditions of three kinds of outdoor air conditioners. The effect of EER and grooves area on the air conditioner. The three installation conditions of the indoor and outdoor units in the grooves are that the same plane is installed vertically with each other (the two outdoor units are at the same height, The length extension line of the outdoor unit intersects perpendicularly with each other, and is installed horizontally in the same plane (the two units are at the same height, the length extension line of the outdoor unit is collinear) and along the outer wall vertically (at different heights). The experimental results show that when the two outdoor units are installed vertically on the same plane, it is suggested that the horizontal spacing (parallel to the outer wall of D1 鈮，
