北京青年報記者近日從北京市農委獲悉,北京市在推進農村“煤改電”過程中,禁止推廣使用直熱式電取暖設備,年內將替換更新所有試點安裝的直熱式電暖器,推廣使用能效比較高的空氣源熱泵、地源(yuan)熱泵和高(gao)能效低(di)排放(fang)燃(ran)氣(qi)取(qu)暖設(she)備。
據市(shi)(shi)農委(wei)相關負責人介紹,本市(shi)(shi)2013年開始啟(qi)動 “煤(mei)改(gai)電(dian)(dian)(dian)(dian)”試(shi)點后,當時(shi)市(shi)(shi)場上比較成(cheng)熟(shu)的電(dian)(dian)(dian)(dian)取(qu)暖(nuan)(nuan)(nuan)設備(bei)(bei)多(duo)為直熱式(shi)電(dian)(dian)(dian)(dian)暖(nuan)(nuan)(nuan)器(qi),還有在東、西城區“煤(mei)改(gai)電(dian)(dian)(dian)(dian)”中推(tui)廣(guang)的蓄(xu)能式(shi)電(dian)(dian)(dian)(dian)暖(nuan)(nuan)(nuan)器(qi)。同時(shi),空(kong)氣(qi)源熱泵也在郊區個別村進行試(shi)點。通過兩年來多(duo)種(zhong)取(qu)暖(nuan)(nuan)(nuan)設備(bei)(bei)使用(yong)效果的對比,發現(xian)(xian)直熱式(shi)電(dian)(dian)(dian)(dian)暖(nuan)(nuan)(nuan)器(qi)雖然熱得快,也能滿足農戶取(qu)暖(nuan)(nuan)(nuan)要求,但(dan)耗能太(tai)多(duo),電(dian)(dian)(dian)(dian)費太(tai)高(gao),不(bu)太(tai)適合推(tui)廣(guang)使用(yong)。蓄(xu)能式(shi)電(dian)(dian)(dian)(dian)暖(nuan)(nuan)(nuan)器(qi)利用(yong)晚上谷電(dian)(dian)(dian)(dian)儲能具有一定(ding)優勢,空(kong)氣(qi)源熱泵則顯現(xian)(xian)出能效比高(gao)、室(shi)內溫度有保障等(deng)優點。
因此在2015年(nian)“煤改(gai)電(dian)(dian)”中(zhong)市政(zheng)(zheng)府提出不再鼓勵推廣(guang)使用直(zhi)(zhi)熱(re)(re)式電(dian)(dian)暖器,繼(ji)續試點空(kong)氣(qi)源熱(re)(re)泵。同(tong)時,市農(nong)委要求各區(qu)主(zhu)動采(cai)取(qu)措施(shi),爭(zheng)取(qu)使用各區(qu)自(zi)有財(cai)政(zheng)(zheng)資金,在去(qu)年(nian)對直(zhi)(zhi)熱(re)(re)式或蓄能(neng)電(dian)(dian)暖器進(jin)行補貼更換(huan)。目前(qian),門頭(tou)溝(gou)、通州、順義、大興等(deng)大多數區(qu)已對這些取(qu)暖設備進(jin)行了更換(huan)。今年(nian)內(nei),僅(jin)剩的房(fang)山區(qu)25個試點村,也將完成(cheng)直(zhi)(zhi)熱(re)(re)式電(dian)(dian)暖器的升(sheng)級(ji)更換(huan)。
據介紹,空氣源熱泵(beng)和地源熱泵在今年整(zheng)個取暖季最冷的(de)(de)一天(2017年1月21日,氣溫(wen)-10℃)平均(jun)室內溫(wen)度(du)達到(dao)了19.1℃。市電(dian)力公司用電(dian)信息(xi)采集(ji)系統對(dui)14個區(qu)21萬(wan)“煤改電(dian)”用戶(hu)(hu)用電(dian)情況進行的(de)(de)統計(ji)顯示(shi),戶(hu)(hu)日均(jun)用電(dian)量為(wei)44.07度(du),整(zheng)個供暖季戶(hu)(hu)均(jun)用電(dian)量為(wei)5528.4度(du),戶(hu)(hu)均(jun)電(dian)費(fei)(fei)約(yue)2135.6元;享(xiang)受政府電(dian)費(fei)(fei)補貼(tie)后(hou),戶(hu)(hu)均(jun)支出電(dian)費(fei)(fei)約(yue)1661.1元。
