一項規定家(jia)用(yong)(yong)電(dian)磁灶能(neng)效(xiao)限定值(zhi)、節能(neng)評(ping)價值(zhi)、能(neng)源效(xiao)率等級(ji)和(he)目標(biao)能(neng)效(xiao)限定值(zhi)的強制性國(guo)(guo)家(jia)標(biao)準已由(you)國(guo)(guo)家(jia)質檢(jian)總局和(he)國(guo)(guo)家(jia)標(biao)準委于2月18日批(pi)準發布，將于9月1日起實(shi)施。按(an)照該(gai)標(biao)準規定的能(neng)效(xiao)限定值(zhi)，目前(qian)市場上10%～15%的家(jia)用(yong)(yong)電(dian)磁灶將被淘(tao)汰。
這(zhe)是一(yi)項(xiang)(xiang)與(yu)《節能(neng)法》配套的(de)(de)能(neng)效(xiao)標準，這(zhe)項(xiang)(xiang)標準即《家用(yong)電(dian)磁(ci)(ci)灶(zao)(zao)(zao)能(neng)效(xiao)限定值(zhi)及能(neng)源效(xiao)率等級》（GB21456-2008）。據(ju)介紹，電(dian)磁(ci)(ci)灶(zao)(zao)(zao)利(li)用(yong)電(dian)磁(ci)(ci)感應(ying)渦流生熱(re)原理(li)工作，能(neng)減少熱(re)量傳遞的(de)(de)中間(jian)(jian)環節，可(ke)大大提升制(zhi)熱(re)效(xiao)率，比傳統灶(zao)(zao)(zao)具(ju)(ju)如(ru)電(dian)灶(zao)(zao)(zao)、氣灶(zao)(zao)(zao)節省能(neng)源一(yi)半以上。電(dian)磁(ci)(ci)灶(zao)(zao)(zao)適(shi)于煎、炒(chao)、炸、煮、燉，潔凈、高效(xiao)、最大限度地節約了(le)廚房空間(jian)(jian)，具(ju)(ju)有獨特的(de)(de)競爭(zheng)優勢。2006年(nian)國內市場的(de)(de)銷(xiao)售(shou)量已經突破1500萬臺，正逐漸(jian)成為(wei)主要家電(dian)產品(pin)和家庭用(yong)電(dian)大戶(hu)。
這項標(biao)(biao)(biao)準(zhun)(zhun)(zhun)(zhun)于2006年(nian)5月開(kai)始制(zhi)定(ding)(ding)(ding)，2007年(nian)9月通過審定(ding)(ding)(ding)。據標(biao)(biao)(biao)準(zhun)(zhun)(zhun)(zhun)主(zhu)要(yao)起(qi)草人、中(zhong)國(guo)標(biao)(biao)(biao)準(zhun)(zhun)(zhun)(zhun)化研(yan)究院能(neng)(neng)(neng)(neng)(neng)(neng)效(xiao)(xiao)(xiao)標(biao)(biao)(biao)識管(guan)理(li)中(zhong)心副(fu)主(zhu)任王若(ruo)虹(hong)介紹，該標(biao)(biao)(biao)準(zhun)(zhun)(zhun)(zhun)主(zhu)要(yao)包括5方面(mian)的(de)(de)(de)(de)(de)(de)(de)內容，一是(shi)(shi)(shi)(shi)規(gui)定(ding)(ding)(ding)了(le)標(biao)(biao)(biao)準(zhun)(zhun)(zhun)(zhun)實施(shi)(shi)時作(zuo)為(wei)(wei)(wei)強制(zhi)性指標(biao)(biao)(biao)的(de)(de)(de)(de)(de)(de)(de)能(neng)(neng)(neng)(neng)(neng)(neng)效(xiao)(xiao)(xiao)限定(ding)(ding)(ding)值(zhi)，作(zuo)為(wei)(wei)(wei)國(guo)家對電磁(ci)(ci)灶(zao)行業監督管(guan)理(li)，防止能(neng)(neng)(neng)(neng)(neng)(neng)效(xiao)(xiao)(xiao)水平低的(de)(de)(de)(de)(de)(de)(de)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)進入市(shi)場以及淘(tao)汰(tai)高耗(hao)能(neng)(neng)(neng)(neng)(neng)(neng)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)的(de)(de)(de)(de)(de)(de)(de)依據。標(biao)(biao)(biao)準(zhun)(zhun)(zhun)(zhun)規(gui)定(ding)(ding)(ding)，額定(ding)(ding)(ding)功(gong)(gong)率(lv)(lv)(lv)小于等(deng)于1200瓦(wa)的(de)(de)(de)(de)(de)(de)(de)加熱(re)(re)(re)單(dan)(dan)元(yuan)的(de)(de)(de)(de)(de)(de)(de)能(neng)(neng)(neng)(neng)(neng)(neng)效(xiao)(xiao)(xiao)限定(ding)(ding)(ding)值(zhi)應達(da)到(dao)5級(ji)(ji)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)的(de)(de)(de)(de)(de)(de)(de)要(yao)求(qiu)，額定(ding)(ding)(ding)功(gong)(gong)率(lv)(lv)(lv)大(da)(da)于1200瓦(wa)的(de)(de)(de)(de)(de)(de)(de)加熱(re)(re)(re)單(dan)(dan)元(yuan)的(de)(de)(de)(de)(de)(de)(de)能(neng)(neng)(neng)(neng)(neng)(neng)效(xiao)(xiao)(xiao)限定(ding)(ding)(ding)值(zhi)應達(da)到(dao)4級(ji)(ji)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)的(de)(de)(de)(de)(de)(de)(de)要(yao)求(qiu)，電磁(ci)(ci)灶(zao)所有(you)加熱(re)(re)(re)單(dan)(dan)元(yuan)均應滿足相應要(yao)求(qiu)，低于規(gui)定(ding)(ding)(ding)能(neng)(neng)(neng)(neng)(neng)(neng)效(xiao)(xiao)(xiao)限定(ding)(ding)(ding)值(zhi)的(de)(de)(de)(de)(de)(de)(de)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)屬于國(guo)家明令淘(tao)汰(tai)的(de)(de)(de)(de)(de)(de)(de)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)，不(bu)(bu)能(neng)(neng)(neng)(neng)(neng)(neng)進入市(shi)場。二是(shi)(shi)(shi)(shi)根據熱(re)(re)(re)效(xiao)(xiao)(xiao)率(lv)(lv)(lv)和(he)待(dai)機(ji)狀態(tai)能(neng)(neng)(neng)(neng)(neng)(neng)耗(hao)規(gui)定(ding)(ding)(ding)了(le)能(neng)(neng)(neng)(neng)(neng)(neng)效(xiao)(xiao)(xiao)等(deng)級(ji)(ji)，標(biao)(biao)(biao)準(zhun)(zhun)(zhun)(zhun)將電磁(ci)(ci)灶(zao)能(neng)(neng)(neng)(neng)(neng)(neng)效(xiao)(xiao)(xiao)等(deng)級(ji)(ji)分(fen)為(wei)(wei)(wei)5級(ji)(ji)，其中(zhong)1級(ji)(ji)能(neng)(neng)(neng)(neng)(neng)(neng)效(xiao)(xiao)(xiao)最高，1～5級(ji)(ji)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)的(de)(de)(de)(de)(de)(de)(de)熱(re)(re)(re)效(xiao)(xiao)(xiao)率(lv)(lv)(lv)值(zhi)分(fen)別為(wei)(wei)(wei)不(bu)(bu)低于90%、88%、86%、84%和(he)82%；1、2級(ji)(ji)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)的(de)(de)(de)(de)(de)(de)(de)待(dai)機(ji)功(gong)(gong)率(lv)(lv)(lv)為(wei)(wei)(wei)不(bu)(bu)大(da)(da)于2瓦(wa)，3、4、5級(ji)(ji)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)的(de)(de)(de)(de)(de)(de)(de)待(dai)機(ji)狀態(tai)功(gong)(gong)率(lv)(lv)(lv)不(bu)(bu)大(da)(da)于5瓦(wa)。三是(shi)(shi)(shi)(shi)規(gui)定(ding)(ding)(ding)了(le)推薦性的(de)(de)(de)(de)(de)(de)(de)節(jie)能(neng)(neng)(neng)(neng)(neng)(neng)評(ping)價值(zhi)為(wei)(wei)(wei)2級(ji)(ji)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)的(de)(de)(de)(de)(de)(de)(de)熱(re)(re)(re)效(xiao)(xiao)(xiao)率(lv)(lv)(lv)值(zhi)和(he)待(dai)機(ji)功(gong)(gong)率(lv)(lv)(lv)，節(jie)能(neng)(neng)(neng)(neng)(neng)(neng)評(ping)價值(zhi)是(shi)(shi)(shi)(shi)開(kai)展(zhan)節(jie)能(neng)(neng)(neng)(neng)(neng)(neng)認(ren)證(zheng)的(de)(de)(de)(de)(de)(de)(de)技術依據，產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)達(da)到(dao)節(jie)能(neng)(neng)(neng)(neng)(neng)(neng)評(ping)價值(zhi)要(yao)求(qiu)可向認(ren)證(zheng)機(ji)構申請節(jie)能(neng)(neng)(neng)(neng)(neng)(neng)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)認(ren)證(zheng)并獲得其頒發的(de)(de)(de)(de)(de)(de)(de)節(jie)能(neng)(neng)(neng)(neng)(neng)(neng)標(biao)(biao)(biao)志和(he)證(zheng)書。四是(shi)(shi)(shi)(shi)規(gui)定(ding)(ding)(ding)了(le)目(mu)(mu)標(biao)(biao)(biao)能(neng)(neng)(neng)(neng)(neng)(neng)效(xiao)(xiao)(xiao)限定(ding)(ding)(ding)值(zhi)，自標(biao)(biao)(biao)準(zhun)(zhun)(zhun)(zhun)實施(shi)(shi)之日(ri)起(qi)4年(nian)后，電磁(ci)(ci)灶(zao)的(de)(de)(de)(de)(de)(de)(de)能(neng)(neng)(neng)(neng)(neng)(neng)效(xiao)(xiao)(xiao)限定(ding)(ding)(ding)值(zhi)待(dai)機(ji)狀態(tai)功(gong)(gong)率(lv)(lv)(lv)為(wei)(wei)(wei)2W，熱(re)(re)(re)效(xiao)(xiao)(xiao)率(lv)(lv)(lv)為(wei)(wei)(wei)86%，即標(biao)(biao)(biao)準(zhun)(zhun)(zhun)(zhun)中(zhong)3級(ji)(ji)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)的(de)(de)(de)(de)(de)(de)(de)能(neng)(neng)(neng)(neng)(neng)(neng)效(xiao)(xiao)(xiao)限定(ding)(ding)(ding)值(zhi)；屆時，目(mu)(mu)前(qian)的(de)(de)(de)(de)(de)(de)(de)4、5級(ji)(ji)產(chan)(chan)(chan)(chan)品(pin)(pin)(pin)將被強制(zhi)淘(tao)汰(tai)。五是(shi)(shi)(shi)(shi)對電磁(ci)(ci)灶(zao)的(de)(de)(de)(de)(de

標準制定的(de)(de)過程中充分考慮了(le)影(ying)響(xiang)(xiang)電(dian)磁灶能效(xiao)的(de)(de)各種(zhong)因(yin)素，主(zhu)要有鍋(guo)具(ju)(ju)的(de)(de)影(ying)響(xiang)(xiang)、環(huan)境(jing)因(yin)素的(de)(de)影(ying)響(xiang)(xiang)、水溫(wen)均勻性的(de)(de)影(ying)響(xiang)(xiang)和(he)不(bu)(bu)(bu)同(tong)(tong)功率段(duan)熱效(xiao)率的(de)(de)影(ying)響(xiang)(xiang)等。如(ru)鍋(guo)具(ju)(ju)通過鍋(guo)壁的(de)(de)傳(chuan)導、對流、輻射等作用向外界散失熱量，不(bu)(bu)(bu)同(tong)(tong)溫(wen)度或者同(tong)(tong)一(yi)溫(wen)度是否(fou)存在空氣對流的(de)(de)使(shi)用環(huan)境(jing)對熱效(xiao)率測試結(jie)(jie)果(guo)的(de)(de)差異，鍋(guo)具(ju)(ju)內不(bu)(bu)(bu)同(tong)(tong)位置水溫(wen)影(ying)響(xiang)(xiang)熱效(xiao)率的(de)(de)測試結(jie)(jie)果(guo)，電(dian)磁灶不(bu)(bu)(bu)同(tong)(tong)加熱功率段(duan)的(de)(de)熱效(xiao)率變(bian)化趨勢并不(bu)(bu)(bu)一(yi)致等，起草(cao)組根(gen)據上述影(ying)響(xiang)(xiang)因(yin)素對檢測方法進行了(le)細(xi)化和(he)改進。
據介(jie)紹(shao)，標準制(zhi)定過程(cheng)中對各企業的(de)(de)(de)典型(xing)型(xing)號、量(liang)大面廣(guang)的(de)(de)(de)主流型(xing)號的(de)(de)(de)產(chan)品匯集進行(xing)了兩次驗證，驗證表明主流產(chan)品大部分可以達到(dao)能效限(xian)定值的(de)(de)(de)要求。根據目前電(dian)磁灶產(chan)品的(de)(de)(de)能源消耗情況，標準實施(shi)后，將有10～15%的(de)(de)(de)高耗能產(chan)品淘汰(tai)被淘汰(tai)。
