即熱式熱水器和儲水式熱水器哪個好
1、外觀與體積
儲水式電熱(re)水器帶一(yi)個大水桶,通(tong)常(chang)40升到100升,安裝(zhuang)的(de)時(shi)候墻(qiang)壁需要是承重墻(qiang),若裝(zhuang)在浴室還占地(di)方(fang),而且影響(xiang)美觀。即熱(re)式的(de)熱(re)水器就相對小巧精致,通(tong)常(chang)就是17寸液晶顯示器盒子(zi)這(zhe)么(me)大,不同的(de)外形,安裝(zhuang)方(fang)便。
2、功率、電壓
即熱式熱水器功(gong)率(lv)通(tong)常在5500瓦(wa)(wa)(wa)以(yi)(yi)上,廚房里的(de)(de)(de)小廚寶一般是(shi)5500瓦(wa)(wa)(wa),用于洗(xi)手洗(xi)菜,而洗(xi)澡(zao)用的(de)(de)(de)熱(re)(re)水器就要6500瓦(wa)(wa)(wa)以(yi)(yi)上才(cai)能達到較好的(de)(de)(de)洗(xi)浴效果。儲水式(shi)(shi)的(de)(de)(de)熱(re)(re)水器通(tong)常1000瓦(wa)(wa)(wa)以(yi)(yi)上,比較多的(de)(de)(de)是(shi)2000瓦(wa)(wa)(wa)左右。那即(ji)熱(re)(re)式(shi)(shi)的(de)(de)(de)熱(re)(re)水器功(gong)率(lv)那么高是(shi)不是(shi)對電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)壓(ya)(ya)(ya)(ya)的(de)(de)(de)要求(qiu)(qiu)也很高呢?其實是(shi)的(de)(de)(de),6500瓦(wa)(wa)(wa)到7500瓦(wa)(wa)(wa)的(de)(de)(de)即(ji)熱(re)(re)式(shi)(shi)的(de)(de)(de)熱(re)(re)水器要求(qiu)(qiu)4平方(fang)的(de)(de)(de)專(zhuan)線(xian)(xian)(xian),而8500瓦(wa)(wa)(wa)的(de)(de)(de)就要求(qiu)(qiu)6平方(fang)的(de)(de)(de)專(zhuan)線(xian)(xian)(xian),目前市(shi)面上2005年以(yi)(yi)后的(de)(de)(de)房子基(ji)本都(dou)配有4平方(fang)的(de)(de)(de)專(zhuan)線(xian)(xian)(xian)。如(ru)果是(shi)5500瓦(wa)(wa)(wa)的(de)(de)(de)小廚寶那就只需(xu)2.5平方(fang)線(xian)(xian)(xian),基(ji)本所有的(de)(de)(de)家庭電(dian)(dian)線(xian)(xian)(xian)都(dou)符合這要求(qiu)(qiu)。儲水式(shi)(shi)熱(re)(re)水器也只需(xu)2.5平方(fang)線(xian)(xian)(xian)。在電(dian)(dian)壓(ya)(ya)(ya)(ya)要求(qiu)(qiu)方(fang)面,并不是(shi)功(gong)率(lv)高電(dian)(dian)壓(ya)(ya)(ya)(ya)就必須高,功(gong)率(lv)=電(dian)(dian)壓(ya)(ya)(ya)(ya)*電(dian)(dian)流(liu),即(ji)熱(re)(re)式(shi)(shi)的(de)(de)(de)也是(shi)用220伏(fu)。
3、安全性能
目前很多家(jia)庭認為即(ji)熱(re)式(shi)的(de)(de)(de)熱(re)水(shui)(shui)器比儲水(shui)(shui)式(shi)的(de)(de)(de)熱(re)水(shui)(shui)器更不(bu)(bu)安全,功(gong)率(lv)高(gao)更加(jia)容(rong)易漏電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)死人,其實這觀念是不(bu)(bu)對的(de)(de)(de)。漏電(dian)(dian)(dian)(dian)跟(gen)電(dian)(dian)(dian)(dian)線(xian)質量有關系,即(ji)使是2.5平方的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian),如果(guo)不(bu)(bu)符合國家(jia)標準,同樣(yang)容(rong)易漏電(dian)(dian)(dian)(dian)。即(ji)熱(re)式(shi)熱(re)水(shui)(shui)器的(de)(de)(de)功(gong)率(lv)更高(gao),但不(bu)(bu)是更容(rong)易漏電(dian)(dian)(dian)(dian),其危(wei)險程度跟(gen)家(jia)庭普(pu)通電(dian)(dian)(dian)(dian)器一樣(yang)高(gao),只要(yao)漏電(dian)(dian)(dian)(dian),一樣(yang)把人電(dian)(dian)(dian)(dian)死的(de)(de)(de)。人的(de)(de)(de)安全電(dian)(dian)(dian)(dian)壓承受能力是36伏,高(gao)于36伏的(de)(de)(de)電(dian)(dian)(dian)(dian)壓都容(rong)易電(dian)(dian)(dian)(dian)死人。另外即(ji)熱(re)式(shi)的(de)(de)(de)熱(re)水(shui)(shui)器在(zai)防電(dian)(dian)(dian)(dian)方面也取得了重要(yao)的(de)(de)(de)技(ji)術(shu)突破(po),比如隔電(dian)(dian)(dian)(dian)墻、電(dian)(dian)(dian)(dian)子防漏電(dian)(dian)(dian)(dian)保(bao)護裝置等。
4、耗電量
耗電(dian)(dian)量(liang)=功率×時(shi)間(jian),一(yi)千瓦用(yong)一(yi)小(xiao)時(shi)就(jiu)(jiu)是一(yi)度電(dian)(dian)。很(hen)多(duo)人就(jiu)(jiu)覺得(de)儲(chu)(chu)水(shui)式(shi)在功率上是小(xiao)很(hen)多(duo)的(de)(de),用(yong)電(dian)(dian)量(liang)肯定(ding)就(jiu)(jiu)少很(hen)多(duo)。其實從能量(liang)守恒(heng)規律來看(kan),加熱(re)這么多(duo)水(shui)到40℃用(yong)的(de)(de)電(dian)(dian)量(liang)是一(yi)樣的(de)(de),從這個(ge)角度來看(kan),其實即熱(re)式(shi)與(yu)儲(chu)(chu)水(shui)式(shi)耗電(dian)(dian)差(cha)不(bu)多(duo)。但是儲(chu)(chu)水(shui)式(shi)有(you)一(yi)個(ge)大水(shui)箱,內里儲(chu)(chu)的(de)(de)都是熱(re)水(shui),如果(guo)用(yong)不(bu)完,那一(yi)大桶(tong)熱(re)水(shui)就(jiu)(jiu)得(de)浪費不(bu)少電(dian)(dian),還要(yao)不(bu)斷保溫加熱(re),所以總體來說(shuo),儲(chu)(chu)水(shui)式(shi)熱(re)水(shui)器(qi)(qi)對電(dian)(dian)的(de)(de)浪費不(bu)亞于即熱(re)式(shi)熱(re)水(shui)器(qi)(qi)。
5、雙模雙核熱水器
有一種半儲(chu)水(shui)(shui)式(shi)(shi)的(de)(de)熱(re)水(shui)(shui)器叫雙(shuang)模雙(shuang)核熱(re)水(shui)(shui)器,它結合了即(ji)(ji)熱(re)式(shi)(shi)與(yu)儲(chu)水(shui)(shui)式(shi)(shi)的(de)(de)優點,即(ji)(ji)滿足(zu)一些(xie)客(ke)戶要求(qiu)快的(de)(de)需求(qiu),又避免(mian)了大水(shui)(shui)箱熱(re)水(shui)(shui)器的(de)(de)浪費。在(zai)這方面走(zou)在(zai)全國領先地位的(de)(de)是奧特朗開(kai)發的(de)(de)預即(ji)(ji)雙(shuang)模機(ji)。
6、配置
儲(chu)水(shui)式(shi)熱(re)水(shui)器一般配有混(hun)水(shui)閥(fa),即熱(re)式(shi)一般不(bu)需配混(hun)水(shui)閥(fa)。儲(chu)水(shui)式(shi)的(de)混(hun)水(shui)閥(fa)可以調(diao)節熱(re)水(shui)的(de)熱(re)度,即熱(re)式(shi)通(tong)過熱(re)水(shui)器本(ben)身的(de)功率(lv)溫度調(diao)節系統控制出(chu)水(shui)溫度。
