鑒于(yu)軸(zhou)流(liu)(liu)(liu)風(feng)(feng)機(ji)有紊(wen)流(liu)(liu)(liu)區的(de)性能(neng)(neng)特點(dian)，在(zai)(zai)選(xuan)型和(he)使(shi)用(yong)(yong)時，需(xu)要(yao)注意(yi)以下兩(liang)點(dian)：建議使(shi)用(yong)(yong)在(zai)(zai)空曠環境(jing)中(zhong),軸(zhou)流(liu)(liu)(liu)風(feng)(feng)機(ji)的(de)輸(shu)入功率隨系(xi)統靜壓的(de)增大而增大，而在(zai)(zai)紊(wen)流(liu)(liu)(liu)區，輸(shu)入功率的(de)增大幅(fu)度會(hui)更大。因此(ci)，軸(zhou)流(liu)(liu)(liu)風(feng)(feng)機(ji)一(yi)般多(duo)應(ying)用(yong)(yong)在(zai)(zai)有較大空曠環境(jing)的(de)場(chang)合下，可以使(shi)其工作在(zai)(zai)靜壓較低(di)的(de)環境(jing)下，降(jiang)低(di)功耗，保證穩定(ding)性和(he)壽命。定(ding)期(qi)清理風(feng)(feng)道(dao)(dao),當軸(zhou)流(liu)(liu)(liu)風(feng)(feng)機(ji)應(ying)用(yong)(yong)在(zai)(zai)較為封閉的(de)風(feng)(feng)道(dao)(dao)系(xi)統中(zhong)時，長期(qi)運行(xing)(xing)后風(feng)(feng)道(dao)(dao)中(zhong)的(de)積灰、垃圾逐(zhu)漸(jian)變(bian)多(duo)，會(hui)使(shi)風(feng)(feng)道(dao)(dao)內的(de)靜壓逐(zhu)漸(jian)增加(jia)，使(shi)得風(feng)(feng)機(ji)的(de)運行(xing)(xing)工況點(dian)逐(zhu)漸(jian)左(zuo)移。這不僅會(hui)降(jiang)低(di)風(feng)(feng)機(ji)性能(neng)(neng)，更重要(yao)的(de)是會(hui)增加(jia)軸(zhou)流(liu)(liu)(liu)風(feng)(feng)機(ji)進(jin)入紊(wen)流(liu)(liu)(liu)區的(de)風(feng)(feng)險。因此(ci)必須要(yao)定(ding)期(qi)清理風(feng)(feng)道(dao)(dao)，保證風(feng)(feng)機(ji)工況點(dian)不產生較大偏移。

層高(gao)(gao)(gao)過(guo)高(gao)(gao)(gao)如何提高(gao)(gao)(gao)制冷效果,解決方案：較之(zhi)(zhi)于常規層高(gao)(gao)(gao)的(de)(de)房屋（一(yi)般(ban)(ban)為(wei)2.6-2.7米左右(you)）。別墅(shu)的(de)(de)層高(gao)(gao)(gao)一(yi)般(ban)(ban)都為(wei)3米甚至以上的(de)(de)高(gao)(gao)(gao)度。此前提下中(zhong)央空調(diao)(diao)制冷和(he)采(cai)暖的(de)(de)配比(bi)較之(zhi)(zhi)于一(yi)般(ban)(ban)層高(gao)(gao)(gao)的(de)(de)房屋會更高(gao)(gao)(gao)。如一(yi)般(ban)(ban)平層的(de)(de)配比(bi)為(wei)200w/平方。別墅(shu)為(wei)230-280w/平方。空調(diao)(diao)外機(ji)(ji)(ji)需要(yao)如何擺放較為(wei)合理,解決方案：別墅(shu)由(you)于面積(ji)較大(da)，較之(zhi)(zhi)于平層一(yi)般(ban)(ban)外機(ji)(ji)(ji)的(de)(de)功率較大(da)。體積(ji)也就較之(zhi)(zhi)平層會更大(da)。一(yi)般(ban)(ban)的(de)(de)擺放位(wei)置位(wei)于本身(shen)建筑的(de)(de)自留機(ji)(ji)(ji)位(wei)或者位(wei)于門口(kou)或者陽臺花園的(de)(de)平臺之(zhi)(zhi)上。鋪設可供(gong)平衡的(de)(de)水泥臺面即可。
