冷負(fù)荷計(jì)算步驟

1、4.1.1冷負(fù)荷計(jì)算：冷負(fù)荷計(jì)算是空調(diào)設(shè)計(jì)及空調(diào)設(shè)備選型的主要依據(jù)；夏季冷負(fù)荷采用冷負(fù)荷系數(shù)法計(jì)算，求出每個房間的逐時值。查實(shí)用供熱空調(diào)設(shè)計(jì)手冊、供暖通風(fēng)與空氣調(diào)節(jié)附錄和采暖通風(fēng)與空氣調(diào)節(jié)設(shè)計(jì)規(guī)范gb500192005得：屋面構(gòu)造如圖所示，從上到下為：1、 防水層加小豆面2、 水泥砂漿找平層3、 屋面板4、 吊頂空間5、 保溫層（瀝青礦渣棉=90mm）6、 隔氣層7、 石膏板屬于型，傳熱系數(shù)=0.53 w/.，屋面吸收系數(shù)修正值kb=0.88外墻體構(gòu)造如圖：1、 水泥砂漿抹灰、噴漿2、 磚墻=370mm3、 保溫層（瀝青膨脹珍珠巖=110mm）4、 內(nèi)粉刷加油漆屬于型，傳熱系數(shù)=0.59 w/

2、.，外墻吸收系數(shù)修正值kb=0.94(外墻顏色為淺色)內(nèi)墻構(gòu)造圖：傳熱系數(shù)=1.75 w/.外窗：三波塑鋼窗，氬氣層12.7mm，兩層鍍low-e膜，e=0.1，傳熱系數(shù)=1.61 w/.金屬窗框80%玻璃，修正系數(shù)cw=1.00玻璃窗的地點(diǎn)修正值td=2窗玻璃遮擋系數(shù)：cs=0.78窗內(nèi)遮陽設(shè)施的遮陽系數(shù)：ci=0.60（淺藍(lán)布簾）窗有效面積系數(shù)ca=0.85辦公室群集系數(shù)：=0.97照明功率：25w/m2 n1=1.0 n2=0.7所用公式：外墻和屋面瞬變傳熱引起的冷負(fù)荷外墻傳熱系數(shù)與內(nèi)墻相同，即k=0.97w/.；根據(jù)夏季室外風(fēng)速為2.8m/s，查空氣調(diào)節(jié)設(shè)計(jì)手冊表2-8，用內(nèi)插法求得w

3、=23.48w/.；再由此查空調(diào)負(fù)荷實(shí)用計(jì)算法表3-6得ka=0.97，查表3-7得外墻kb=0.94(外墻顏色為淺色)，屋面kb=0.88，由表3-3查得型外墻不同朝向逐時的tj值。則tj=(tj+td)kakb ，外墻冷負(fù)荷計(jì)算公式： （4.1）由于該建筑外表面都為玻璃幕墻，有的房間外墻面積所占外維護(hù)結(jié)構(gòu)面積比例很小，可忽略不計(jì)；房間0501、0502、0504、0507、0509、0510、0511外墻冷負(fù)荷忽略不計(jì)。外玻璃窗瞬變傳熱引起的冷負(fù)荷查空調(diào)負(fù)荷實(shí)用計(jì)算法表3-11得玻璃窗冷負(fù)荷計(jì)算溫度tj ，再查表3-12得玻璃窗地點(diǎn)修正值td，則tj=(tj+td)ka ，玻璃窗瞬變傳熱引

4、起的冷負(fù)荷計(jì)算公式： （4.2）式中 qcl 外玻璃窗瞬變傳熱引起的冷負(fù)荷，w； k 外玻璃窗傳熱系數(shù)，w/(m2 )； f 窗口面積，m2； tj 外玻璃窗的冷負(fù)荷溫度的逐時值，； tn 地點(diǎn)修正值；透過玻璃窗的日射得熱引起的冷負(fù)荷查空調(diào)負(fù)荷實(shí)用計(jì)算法表2-2得玻璃窗的cs值為0.516，查表2-3得窗內(nèi)遮陽設(shè)施的遮陽系數(shù)cn=0.60（內(nèi)遮陽為活動百葉簾），查表2-1得夏季日射得熱因數(shù)最大值djmax ：南：251w/ 東：575w/ 北：122w/ 西：575w/查表2-6得北區(qū)有內(nèi)遮陽窗玻璃冷負(fù)荷系數(shù)ccl值。 玻璃窗日射得熱引起的冷負(fù)荷計(jì)算公式： （4.3） cz= ccn （4.4

7、環(huán)境條件(溫、濕度)等多種因素有關(guān)。從性別上看，可認(rèn)為成年女子總散熱量約為男子的85%，兒童約為75%。由于性質(zhì)不同的建筑物中有不同比例的成年男子，女子和兒童數(shù)量，而成年女子和兒童的散熱量低于成年男子。為了實(shí)際計(jì)算方便，可以成年男子為基礎(chǔ)，乘以考慮了各類人員組成比例的系數(shù)，稱群集系數(shù)。人體顯熱散熱形成的逐時冷負(fù)荷為： （4.8）式中 qx 不同室溫和勞動性質(zhì)成年男子顯熱散熱量，w； qq 不同室溫和勞動性質(zhì)成年男子潛熱散熱量，w；n 室內(nèi)全部人數(shù)； 群集系數(shù)；ccl 人體顯熱散熱冷負(fù)荷系數(shù)；501房間：內(nèi)圍護(hù)結(jié)構(gòu)冷負(fù)荷： （4.5）k=0.97f=(7.7+1.7+8)3.5=59.15t=5
