溫(wen)(wen)(wen)控(kong)器作為(wei)控(kong)制(zhi)系統(tong)的重要組(zu)成部分(fen),其重要性不(bu)言而喻(yu),其安(an)裝(zhuang)好壞直接影響到(dao)系統(tong)的應用(yong)。溫(wen)(wen)(wen)控(kong)有總(zong)體控(kong)制(zhi)和分(fen)環路控(kong)制(zhi)兩種方案,那(nei)么在(zai)設計(ji)、安(an)裝(zhuang)溫(wen)(wen)(wen)控(kong)器中有哪些注意事項?
很多(duo)人認為(wei)溫控器的安(an)裝是靠“經(jing)驗”安(an)裝,但是暖(nuan)規和(he)地(di)暖(nuan)規程對于溫控的設(she)計(ji)與(yu)安(an)裝都有要(yao)求,比如《民(min)用建(jian)筑(zhu)供(gong)暖(nuan)通風與(yu)空氣調節設(she)計(ji)規范》第5.10.1條(tiao):集中供暖的新(xin)建建筑和既有(you)建筑節能(neng)(neng)改造(zao)必(bi)須設置(zhi)熱計(ji)量裝置(zhi),并具備(bei)室溫調控的功能(neng)(neng)。《輻射(she)供暖供冷技術規程》本文(wen)簡稱 “地暖規(gui)程”)第3.8.1條:新建住宅熱(re)水輻(fu)射供(gong)暖(nuan)系統應設置分戶計量和室溫調控裝置。所謂的室溫調控無非是(shi)在干(gan)管或支管上加裝溫控閥(fa)。
總的(de)來說有總體控制(zhi)和分環路控制(zhi)兩種方案,先說總體控制(zhi),一般(ban)的(de)住宅,辦公(gong)室(shi)適用(yong)總體控制(zhi),這(zhe)種方式(shi)(shi)適用(yong)于各個環路長度(du)接近(jin)的(de)系統,不能(neng)對單(dan)獨(du)房間(jian)做出(chu)調節(jie)(jie)動(dong)(dong)作,在分水器的(de)干管上(shang)加(jia)裝(zhuang)自(zi)動(dong)(dong)恒溫(wen)(wen)閥。請注意我們(men)要安裝(zhuang)的(de)不是(shi)手動(dong)(dong)調節(jie)(jie)的(de)“實芯”銅閥,而(er)是(shi)復雜的(de)電(dian)熱式(shi)(shi)、自(zi)力式(shi)(shi)具有自(zi)動(dong)(dong)調節(jie)(jie)功(gong)能(neng)的(de)閥門,或(huo)者電(dian)動(dong)(dong)閥。這(zhe)些閥門的(de)感溫(wen)(wen)機構能(neng)夠(gou)感受(shou)室(shi)內溫(wen)(wen)度(du),并根(gen)據(ju)感受(shou)的(de)參(can)量對閥門開度(du)進行控制(zhi),從而(er)達到調節(jie)(jie)室(shi)溫(wen)(wen)的(de)目(mu)的(de)。
當(dang)然,室(shi)內溫(wen)(wen)(wen)度(du)是可以設定的。如果(guo)集(ji)分水(shui)(shui)器(qi)和支管明裝(zhuang)(zhuang),一(yi)(yi)般說(shuo)來可以安(an)裝(zhuang)(zhuang)一(yi)(yi)體式(shi)溫(wen)(wen)(wen)控(kong)閥(fa)。請注意,如果(guo)集(ji)分水(shui)(shui)器(qi)和支管暗(an)裝(zhuang)(zhuang),就需要(yao)(yao)安(an)裝(zhuang)(zhuang)外置式(shi)室(shi)溫(wen)(wen)(wen)控(kong)制器(qi)了,因為(wei)暗(an)裝(zhuang)(zhuang)的時候,一(yi)(yi)體式(shi)溫(wen)(wen)(wen)控(kong)閥(fa)感受到的是暗(an)裝(zhuang)(zhuang)箱(xiang)(xiang)、柜內狹小(xiao)(xiao)空間的溫(wen)(wen)(wen)度(du),不(bu)(bu)能(neng)正(zheng)確(que)感受到室(shi)內的溫(wen)(wen)(wen)度(du),就起不(bu)(bu)到調節作用了。相反(fan),暗(an)裝(zhuang)(zhuang)集(ji)分水(shui)(shui)器(qi)箱(xiang)(xiang)、柜內溫(wen)(wen)(wen)度(du)一(yi)(yi)般溫(wen)(wen)(wen)度(du)較高,致使閥(fa)門(men)開度(du)自(zi)動變小(xiao)(xiao),自(zi)然就會影響到供(gong)暖(nuan)效果(guo)了。溫(wen)(wen)(wen)控(kong)閥(fa)、集(ji)分水(shui)(shui)器(qi)暗(an)裝(zhuang)(zhuang)的時候,一(yi)(yi)定要(yao)(yao)外置保溫(wen)(wen)(wen)機構,而且這個室(shi)溫(wen)(wen)(wen)控(kong)制器(qi)一(yi)(yi)定要(yao)(yao)放在能(neng)正(zheng)確(que)反(fan)應室(shi)溫(wen)(wen)(wen)的地方,不(bu)(bu)能(neng)被(bei)遮擋(dang),不(bu)(bu)能(neng)被(bei)太陽直(zhi)射,不(bu)(bu)能(neng)貼鄰發(fa)熱量的物(wu)體……
分環路控制的注(zhu)意事(shi)項:
接下來(lai)談(tan)談(tan)分(fen)環(huan)(huan)路控制(zhi)(zhi),這(zhe)種方式適用于高級住(zhu)宅、別(bie)墅、主(zhu)要(yao)房(fang)(fang)間(jian)(jian)(jian)單獨成(cheng)環(huan)(huan)路的(de)(de)(de)系(xi)統。其(qi)實就是(shi)每個環(huan)(huan)路都(dou)設一(yi)套溫(wen)(wen)控閥(fa)門,有(you)內置(zhi)(zhi)在集水器(qi)上的(de)(de)(de),也有(you)在集水器(qi)外部貼鄰其(qi)安裝。這(zhe)種做(zuo)(zuo)法需(xu)要(yao)向(xiang)各(ge)個房(fang)(fang)間(jian)(jian)(jian)分(fen)別(bie)跑線,每個房(fang)(fang)間(jian)(jian)(jian)都(dou)需(xu)要(yao)安裝室溫(wen)(wen)控制(zhi)(zhi)器(qi)。由(you)(you)每個房(fang)(fang)間(jian)(jian)(jian)的(de)(de)(de)室溫(wen)(wen)控制(zhi)(zhi)內的(de)(de)(de)感溫(wen)(wen)機構感受(shou)該(gai)房(fang)(fang)間(jian)(jian)(jian)的(de)(de)(de)溫(wen)(wen)度(du),并與該(gai)房(fang)(fang)間(jian)(jian)(jian)的(de)(de)(de)設定溫(wen)(wen)度(du)對(dui)(dui)(dui)(dui)比,做(zuo)(zuo)出(chu)相(xiang)應的(de)(de)(de)動作,以調節各(ge)房(fang)(fang)間(jian)(jian)(jian)流(liu)量,從而(er)達到(dao)控制(zhi)(zhi)房(fang)(fang)間(jian)(jian)(jian)溫(wen)(wen)度(du)。相(xiang)對(dui)(dui)(dui)(dui)總體控制(zhi)(zhi),控制(zhi)(zhi)相(xiang)對(dui)(dui)(dui)(dui)復(fu)雜。由(you)(you)于需(xu)要(yao)對(dui)(dui)(dui)(dui)各(ge)個房(fang)(fang)間(jian)(jian)(jian)跑線、布置(zhi)(zhi)溫(wen)(wen)控器(qi),給施工帶(dai)來(lai)一(yi)定的(de)(de)(de)麻煩(fan)。
傳統地暖(必須是(shi)有蓄熱(re)層的地暖)具(ju)有(you)熱惰性。不(bu)是你(ni)設好溫(wen)(wen)(wen)(wen)度,室溫(wen)(wen)(wen)(wen)馬上就(jiu)能反(fan)應(ying)過(guo)來的。也許(xu)你(ni)晚上到家調(diao)高溫(wen)(wen)(wen)(wen)度,第二天要(yao)上班的時候溫(wen)(wen)(wen)(wen)度才上來。地(di)(di)暖溫(wen)(wen)(wen)(wen)控的可以在不(bu)同(tong)的時段設定不(bu)同(tong)的運行(xing)溫(wen)(wen)(wen)(wen)度。但請(qing)記住,要(yao)提前加(jia)熱,提前降溫(wen)(wen)(wen)(wen)。與其說溫(wen)(wen)(wen)(wen)控意義在于(yu)節(jie)能,不(bu)如說地(di)(di)暖溫(wen)(wen)(wen)(wen)控讓(rang)我們(men)更舒適。合(he)理適用溫(wen)(wen)(wen)(wen)控裝置,我們(men)起(qi)碼不(bu)會再為過(guo)熱而煩惱(nao)。
冬季(ji)通熱(re)水(shui)供暖,夏季(ji)通冷(leng)水(shui)供冷(leng)。住在(zai)頂(ding)層,屋頂(ding)是坡屋頂(ding),室內(nei)吊頂(ding)是石膏板。只要(yao)切(qie)一(yi)條(tiao)跑水(shui)管就可以了(le)。只要(yao)點點管材、配件(jian)還(huan)有二(er)次局(ju)部(bu)裝(zhuang)修的費用,整個改造下來有2000元出頭就(jiu)差不多(duo)了,所有的劃(hua)分不過一(yi)臺壁掛式分體(ti)空調(diao)的費用。
