空(kong)調與(yu)電(dian)暖器誰費電(dian)些？一般空(kong)調加(jia)熱(re)的原(yuan)理是熱(re)泵,在內部(bu)完成一個完整的熱(re)量循環(huan)，而(er)取(qu)暖器的加(jia)熱(re)原(yuan)理是電(dian)熱(re)絲，依靠高低溫差循環(huan)散熱(re)。熱(re)交換方式的區別，也決定了(le)二者耗電(dian)的區別。

如果用空(kong)(kong)調(diao)的(de)(de)耗(hao)(hao)電(dian)(dian)(dian)(dian)量(liang)(liang)和(he)電(dian)(dian)(dian)(dian)暖氣的(de)(de)耗(hao)(hao)電(dian)(dian)(dian)(dian)量(liang)(liang)相(xiang)比，電(dian)(dian)(dian)(dian)暖氣比空(kong)(kong)調(diao)加的(de)(de)費(fei)電(dian)(dian)(dian)(dian)一(yi)些，可能(neng)(neng)大家不(bu)太能(neng)(neng)夠相(xiang)信，為什么(me)體(ti)積比較小的(de)(de)電(dian)(dian)(dian)(dian)暖氣它的(de)(de)耗(hao)(hao)電(dian)(dian)(dian)(dian)量(liang)(liang)反(fan)而(er)比空(kong)(kong)調(diao)高(gao)吧(ba)。電(dian)(dian)(dian)(dian)器它的(de)(de)耗(hao)(hao)電(dian)(dian)(dian)(dian)量(liang)(liang)其實(shi)和(he)它的(de)(de)運(yun)行(xing)功(gong)率是相(xiang)關的(de)(de)，就拿一(yi)批(pi)的(de)(de)空(kong)(kong)調(diao)來(lai)說(shuo)吧(ba)，一(yi)般一(yi)匹空(kong)(kong)調(diao)它的(de)(de)額(e)定(ding)功(gong)率是在(zai)1000W左右，在(zai)運(yun)行(xing)的(de)(de)時候它一(yi)個(ge)小時的(de)(de)耗(hao)(hao)電(dian)(dian)(dian)(dian)量(liang)(liang)可能(neng)(neng)達不(bu)到1度，而(er)電(dian)(dian)(dian)(dian)暖氣它的(de)(de)運(yun)行(xing)功(gong)率要比空(kong)(kong)調(diao)大一(yi)些，在(zai)使用的(de)(de)時候它一(yi)個(ge)小時的(de)(de)耗(hao)(hao)電(dian)(dian)(dian)(dian)量(liang)(liang)至少都會有1度，因(yin)此(ci)和(he)空(kong)(kong)調(diao)相(xiang)比電(dian)(dian)(dian)(dian)暖器加的(de)(de)費(fei)電(dian)(dian)(dian)(dian)一(yi)些。

目(mu)前(qian)，市面(mian)上這種說法(fa)比較普遍。說的(de)是(shi)(shi)空(kong)調和電(dian)(dian)(dian)取(qu)暖器(qi)的(de)熱交換方(fang)式不一樣，空(kong)調制熱取(qu)暖是(shi)(shi)在(zai)消(xiao)耗(hao)(hao)電(dian)(dian)(dian)力的(de)同(tong)時從室外環(huan)境(jing)空(kong)氣中(zhong)吸收很多熱量(liang)轉移(yi)到室內(nei)，平(ping)均水(shui)平(ping)來說空(kong)調制熱每消(xiao)耗(hao)(hao)1度電(dian)(dian)(dian)能夠額外從室外轉移(yi)相當(dang)于2度電(dian)(dian)(dian)的(de)熱量(liang)到室內(nei)；而取(qu)暖器(qi)只是(shi)(shi)在(zai)消(xiao)耗(hao)(hao)電(dian)(dian)(dian)量(liang)把電(dian)(dian)(dian)轉化成熱量(liang)，在(zai)取(qu)得同(tong)等取(qu)暖效(xiao)果(guo)的(de)前(qian)提下取(qu)暖器(qi)的(de)耗(hao)(hao)電(dian)(dian)(dian)量(liang)比空(kong)調取(qu)暖的(de)耗(hao)(hao)電(dian)(dian)(dian)量(liang)要大些。

對此，相關業內人(ren)(ren)(ren)士(shi)分(fen)析表示，僅(jin)僅(jin)是(shi)從能量轉換的(de)(de)角度(du)(du)上(shang)講空(kong)(kong)(kong)調比電暖(nuan)氣(qi)省(sheng)電的(de)(de)結論(lun)有點草(cao)率。理論(lun)跟實際還是(shi)有區別的(de)(de)，熱的(de)(de)空(kong)(kong)(kong)氣(qi)會因(yin)為密度(du)(du)小而(er)(er)上(shang)升，房間內人(ren)(ren)(ren)員(yuan)(yuan)活動區基本(ben)在1.8m左右（1米8以上(shang)高個(ge)人(ren)(ren)(ren)士(shi)排(pai)除在外），空(kong)(kong)(kong)調安裝高度(du)(du)基本(ben)是(shi)在屋子頂(ding)板(ban)上(shang)，靠著里面的(de)(de)風扇進行強制對流傳導熱量，而(er)(er)電暖(nuan)氣(qi)是(shi)在下面，這樣的(de)(de)話，要(yao)同樣人(ren)(ren)(ren)員(yuan)(yuan)活動區的(de)(de)舒適溫度(du)(du)顯(xian)然空(kong)(kong)(kong)調需(xu)要(yao)消耗的(de)(de)能量多。在如地板(ban)輻射，這個(ge)加(jia)的(de)(de)節(jie)省(sheng)能源，而(er)(er)且(qie)人(ren)(ren)(ren)體的(de)(de)舒適度(du)(du)會很(hen)高，因(yin)為熱氣(qi)自下而(er)(er)上(shang)。所以咱們不應該輕易下定論(lun)說空(kong)(kong)(kong)調省(sheng)電。

此外(wai)，如果是小(xiao)范圍取(qu)暖(nuan)(nuan)，而且取(qu)暖(nuan)(nuan)時間(jian)不(bu)長(chang)，那么電(dian)暖(nuan)(nuan)氣(qi)(qi)省(sheng)電(dian)的(de)。電(dian)暖(nuan)(nuan)氣(qi)(qi)相當于(yu)一個小(xiao)風扇對(dui)著一個大(da)功(gong)率電(dian)燈泡吹，于(yu)是就(jiu)會(hui)加(jia)熱空氣(qi)(qi)，形成暖(nuan)(nuan)風。而空調(diao)(diao)開制(zhi)熱時相當于(yu)把室(shi)(shi)內(nei)的(de)冷氣(qi)(qi)吸走，到外(wai)機經(jing)過循(xun)環，加(jia)熱再送至(zhi)室(shi)(shi)內(nei)，空調(diao)(diao)的(de)零件較多(duo)自(zi)然耗電(dian)也較多(duo)，所以市(shi)場(chang)上(shang)大(da)部分的(de)取(qu)暖(nuan)(nuan)器耗電(dian)量都低于(yu)空調(diao)(diao)。
