縮(suo)機采用的是熱(re)泵專(zhuan)用壓(ya)縮(suo)機;第二,空(kong)調(diao)系統(tong)(tong)中壓(ya)力(li)最高為18個(ge),熱(re)泵壓(ya)力(li)最高超過28個(ge),所以(yi)熱(re)泵銅(tong)管要(yao)比空(kong)調(diao)銅(tong)管厚的多;第三,系統(tong)(tong)中空(kong)調(diao)承(cheng)受最高溫度一般不超過40度,而空(kong)氣能熱(re)水器(qi)至少(shao)可以(yi)到達60度,所以(yi)制熱(re)要(yao)求相當(dang)高。
空調(diao)(diao)無論制(zhi)冷還是制(zhi)熱(re)一般(ban)每(mei)天工(gong)(gong)(gong)作(zuo)(zuo)時(shi)(shi)間(jian)都比(bi)較長,而且空調(diao)(diao)工(gong)(gong)(gong)作(zuo)(zuo)的功率要高于空氣(qi)能(neng)(neng)(neng)熱(re)水(shui)器(qi)的工(gong)(gong)(gong)作(zuo)(zuo)功率。空氣(qi)能(neng)(neng)(neng)熱(re)水(shui)器(qi)電源雖然是一直(zhi)通電,但(dan)當制(zhi)熱(re)完(wan)成后,機(ji)組就會停止工(gong)(gong)(gong)作(zuo)(zuo)自(zi)動保(bao)溫,保(bao)溫過(guo)(guo)程不(bu)需要耗電,優質水(shui)箱的保(bao)溫可(ke)以(yi)達(da)100小時(shi)(shi)以(yi)上(shang)。家用(yong)機(ji)一般(ban)每(mei)天工(gong)(gong)(gong)作(zuo)(zuo)不(bu)會超(chao)過(guo)(guo)2小時(shi)(shi),所以(yi)空氣(qi)能(neng)(neng)(neng)熱(re)水(shui)器(qi)要比(bi)空調(diao)(diao)省電很熱(re),且對壓(ya)縮機(ji)保(bao)護(hu)好,使用(yong)壽命更長。
