首先讓我(wo)們以車(che)(che)載空(kong)(kong)(kong)調(diao)為例(li)，使用(yong)空(kong)(kong)(kong)調(diao)時，排(pai)量(liang)小的汽車(che)(che)會(hui)感覺到(dao)油耗的明(ming)顯(xian)增加和(he)功率(lv)的明(ming)顯(xian)下降(jiang)。夏季使用(yong)空(kong)(kong)(kong)調(diao)時，大排(pai)量(liang)車(che)(che)輛(liang)(liang)的油耗沒有明(ming)顯(xian)變化，功率(lv)基(ji)本不受影響。但是(shi)，您絕(jue)對不能認為將(jiang)空(kong)(kong)(kong)調(diao)用(yong)于大排(pai)量(liang)車(che)(che)輛(liang)(liang)會(hui)更經濟，因為大排(pai)量(liang)車(che)(che)輛(liang)(liang)的發動機功率(lv)相對較大，并且空(kong)(kong)(kong)調(diao)負荷影響不大。考慮到(dao)燃油經濟性，小排(pai)量(liang)汽車(che)(che)即使在開啟(qi)空(kong)(kong)(kong)調(diao)的情況下，絕(jue)對也更省(sheng)油。

中(zhong)(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)(kong)(kong)調(diao)和普(pu)通分(fen)體(ti)式(shi)空(kong)(kong)(kong)(kong)(kong)調(diao)也是類似的(de)概念。如(ru)果(guo)只(zhi)打(da)開一(yi)到三(san)個(ge)中(zhong)(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)(kong)(kong)調(diao)的(de)內部單元中(zhong)(zhong)(zhong)(zhong)的(de)一(yi)兩個(ge)，則功(gong)耗(hao)肯(ken)定會比(bi)一(yi)或兩個(ge)分(fen)體(ti)式(shi)空(kong)(kong)(kong)(kong)(kong)調(diao)高(gao)，當然這是基于同等級(ji)空(kong)(kong)(kong)(kong)(kong)調(diao)的(de)比(bi)較。如(ru)果(guo)采(cai)用(yong)(yong)具(ju)有更先進節(jie)(jie)電(dian)(dian)技(ji)術的(de)中(zhong)(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)(kong)(kong)調(diao)，節(jie)(jie)電(dian)(dian)效果(guo)肯(ken)定會比(bi)低端(duan)分(fen)體(ti)式(shi)空(kong)(kong)(kong)(kong)(kong)調(diao)好。家(jia)用(yong)(yong)中(zhong)(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)(kong)(kong)調(diao)的(de)“超(chao)常功(gong)耗(hao)”實際上是一(yi)種誤解。家(jia)用(yong)(yong)中(zhong)(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)(kong)(kong)調(diao)的(de)室(shi)(shi)內機可以單獨打(da)開，需要使(shi)(shi)(shi)用(yong)(yong)的(de)只(zhi)有個(ge)別房(fang)間的(de)室(shi)(shi)內機，未使(shi)(shi)(shi)用(yong)(yong)的(de)室(shi)(shi)內機不消耗(hao)電(dian)(dian)力(li)。室(shi)(shi)外機還會根據(ju)室(shi)(shi)內機的(de)使(shi)(shi)(shi)用(yong)(yong)情況來(lai)調(diao)節(jie)(jie)壓縮機的(de)頻率，因此家(jia)用(yong)(yong)中(zhong)(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)(kong)(kong)調(diao)不會比(bi)分(fen)體(ti)式(shi)空(kong)(kong)(kong)(kong)(kong)調(diao)消耗(hao)更多的(de)電(dian)(dian)能(neng)(neng)。從(cong)長(chang)遠來(lai)看，家(jia)用(yong)(yong)中(zhong)(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)(kong)(kong)調(diao)的(de)總體(ti)運(yun)行成本較低，使(shi)(shi)(shi)用(yong)(yong)壽命更長(chang)，并且更節(jie)(jie)能(neng)(neng)。作(zuo)為(wei)普(pu)通家(jia)用(yong)(yong)電(dian)(dian)器，用(yong)(yong)戶應(ying)仔細考(kao)慮長(chang)期節(jie)(jie)能(neng)(neng)的(de)問題，家(jia)用(yong)(yong)中(zhong)(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)(kong)(kong)調(diao)的(de)節(jie)(jie)能(neng)(neng)性能(neng)(neng)比(bi)傳(chuan)統空(kong)(kong)(kong)(kong)(kong)調(diao)高(gao)20%到30%，在夏(xia)季頻繁使(shi)(shi)(shi)用(yong)(yong)空(kong)(kong)(kong)(kong)(kong)調(diao)，每月可節(jie)(jie)省數百甚(shen)至數千元人(ren)民幣。

此外，由于中(zhong)央空(kong)(kong)調(diao)的(de)出(chu)風口(kou)(kou)位于房間的(de)頂部，因此可以更(geng)好(hao)地幫助房間在(zai)(zai)制冷(leng)過程中(zhong)降溫，其效(xiao)率遠高于壁掛(gua)式空(kong)(kong)調(diao)和柜式空(kong)(kong)調(diao)。但是，在(zai)(zai)冬天取暖(nuan)時，較高的(de)出(chu)風口(kou)(kou)會使更(geng)多的(de)熱(re)量集中(zhong)在(zai)(zai)房間的(de)頂部空(kong)(kong)間，并且采暖(nuan)效(xiao)率會降低。如(ru)果中(zhong)央空(kong)(kong)調(diao)出(chu)風口(kou)(kou)有回光燈槽，將(jiang)進(jin)一(yi)步影響散熱(re)器(qi)，甚至導致空(kong)(kong)調(diao)頻繁關閉(bi)，影響采暖(nuan)效(xiao)果。換句話說，冬季使用中(zhong)央空(kong)(kong)調(diao)供(gong)暖(nuan)將(jiang)比分體(ti)式空(kong)(kong)調(diao)消耗更(geng)多的(de)電力。

總之，中(zhong)(zhong)央(yang)(yang)空(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)(de)優點是(shi)(shi)更(geng)好的(de)(de)(de)舒適性和美(mei)觀性。與(yu)同(tong)檔(dang)次(ci)的(de)(de)(de)分體(ti)式(shi)空(kong)(kong)調(diao)(diao)(diao)(diao)相(xiang)比，中(zhong)(zhong)央(yang)(yang)空(kong)(kong)調(diao)(diao)(diao)(diao)節省更(geng)多(duo)電力。考慮(lv)到(dao)選擇中(zhong)(zhong)央(yang)(yang)空(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)(de)家(jia)(jia)庭(ting)通常會選擇能(neng)(neng)效比更(geng)高的(de)(de)(de)產品，因此許多(duo)中(zhong)(zhong)央(yang)(yang)空(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)(de)功耗要比普通空(kong)(kong)調(diao)(diao)(diao)(diao)低。當然，中(zhong)(zhong)央(yang)(yang)空(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)(de)節電效果也需(xu)要長期使(shi)(shi)用才能(neng)(neng)體(ti)現出來(lai)，如果空(kong)(kong)調(diao)(diao)(diao)(diao)一年使(shi)(shi)用30至40天，一天僅(jin)使(shi)(shi)用幾個小時，則無需(xu)考慮(lv)使(shi)(shi)用中(zhong)(zhong)央(yang)(yang)空(kong)(kong)調(diao)(diao)(diao)(diao)，甚至無需(xu)購買變頻(pin)空(kong)(kong)調(diao)(diao)(diao)(diao)。直接購買固定頻(pin)率的(de)(de)(de)空(kong)(kong)調(diao)(diao)(diao)(diao)器更(geng)具成(cheng)本效益(yi)。但(dan)是(shi)(shi)隨著中(zhong)(zhong)央(yang)(yang)空(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)(de)不(bu)斷發展，未來(lai)的(de)(de)(de)中(zhong)(zhong)央(yang)(yang)空(kong)(kong)調(diao)(diao)(diao)(diao)會越來(lai)越小巧省電，許多(duo)有長遠目光(guang)的(de)(de)(de)家(jia)(jia)庭(ting)現在就已經(jing)裝好了家(jia)(jia)用中(zhong)(zhong)央(yang)(yang)空(kong)(kong)調(diao)(diao)(diao)(diao)，到(dao)時只需(xu)更(geng)新換代即可。
