一、什么是中央熱水器系統
中央熱水器系統(tong)(tong)是(shi)指(zhi)多(duo)處熱水(shui)(shui)采(cai)集點(dian)共用(yong)(yong)一(yi)(yi)個(ge)熱水(shui)(shui)器、各采(cai)集點(dian)之(zhi)間用(yong)(yong)循環管道連(lian)接的系統(tong)(tong),中(zhong)央熱水(shui)(shui)系統(tong)(tong)就是(shi)有集中(zhong)分配熱水(shui)(shui)的含義,熱水(shui)(shui)都(dou)由同一(yi)(yi)地(di)方產生(sheng)(sheng),然(ran)后將熱水(shui)(shui)都(dou)儲存到一(yi)(yi)個(ge)合(he)適容量的保溫水(shui)(shui)箱里,接著通(tong)過管道連(lian)接著水(shui)(shui)箱和各個(ge)用(yong)(yong)水(shui)(shui)區域,當(dang)某一(yi)(yi)處用(yong)(yong)水(shui)(shui)時(shi),水(shui)(shui)箱就會分配熱水(shui)(shui)到既(ji)定區域。中(zhong)央熱水(shui)(shui)系統(tong)(tong)通(tong)常用(yong)(yong)在比如(ru)酒(jiu)店(dian)、招(zhao)待(dai)所、學校、美容中(zhong)心等,另外,有兩個(ge)或多(duo)個(ge)衛生(sheng)(sheng)間的大戶型、復式房屋或公寓、別墅等都(dou)可(ke)以使用(yong)(yong)這(zhe)種中(zhong)央熱水(shui)(shui)器系統(tong)(tong)。
二、中央熱水系統組成
1、熱源
熱(re)(re)源有(you)多種選擇,可以有(you)用(yong)(yong)煤(mei)爐(lu)(lu)、電水(shui)暖(nuan)爐(lu)(lu)、燃氣爐(lu)(lu)、燃油鍋爐(lu)(lu)、太陽能(neng)熱(re)(re)水(shui)、空氣源熱(re)(re)泵(beng)等。根據使用(yong)(yong)實際情況大多采用(yong)(yong)電水(shui)暖(nuan)爐(lu)(lu)或(huo)者(zhe)空氣源熱(re)(re)泵(beng)或(huo)者(zhe)太陽能(neng)。中賀電水(shui)暖(nuan)結(jie)合(he)實際案例和應(ying)用(yong)(yong)效(xiao)果,推薦使用(yong)(yong)太陽能(neng)+電水(shui)暖(nuan)爐(lu)(lu)方式,性能(neng)穩定(ding),無(wu)季(ji)節(jie)變化之憂,節(jie)約(yue)能(neng)源降低費(fei)用(yong)(yong)。
2、換熱
由于水的腐蝕(shi)性和加(jia)熱(re)以結垢,通常為了延長熱(re)源的使用壽命和保證水質。在熱(re)源和蓄熱(re)水箱之間用板式換(huan)熱(re)器或者換(huan)熱(re)翅片。
3、蓄熱
中央熱(re)水(shui)(shui)(shui)為(wei)了保證(zheng)24小時(shi)(shi)隨時(shi)(shi)使用(yong)(yong)熱(re)水(shui)(shui)(shui),一般(ban)都是(shi)蓄(xu)(xu)熱(re)式水(shui)(shui)(shui)箱儲水(shui)(shui)(shui)。水(shui)(shui)(shui)箱大小可(ke)以(yi)根(gen)據使用(yong)(yong)量來確定,一般(ban)賓館洗浴按照50L/人計算(suan)。家庭使用(yong)(yong)可(ke)以(yi)根(gen)據實際人口和用(yong)(yong)途單獨計算(suan)。蓄(xu)(xu)熱(re)水(shui)(shui)(shui)箱的具有可(ke)以(yi)蓄(xu)(xu)能,水(shui)(shui)(shui)溫穩(wen)定、水(shui)(shui)(shui)量由保證(zheng)等特(te)點,尤其是(shi)峰谷電價(jia)表的用(yong)(yong)戶(hu)可(ke)以(yi)低價(jia)時(shi)(shi)段蓄(xu)(xu)熱(re)。
4、循環系統
循環系(xi)統是整個(ge)中央熱水(shui)系(xi)統的心(xin)臟。只有循環水(shui)能(neng)夠保(bao)(bao)證打開(kai)龍(long)頭(tou)出熱水(shui)。一臺好的水(shui)泵是保(bao)(bao)證你隨(sui)時使用的核心(xin)。中賀電(dian)水(shui)暖全部采(cai)用德國威樂水(shui)泵,保(bao)(bao)證您的使用無(wu)憂。
三、中央熱水器的工作原理
中(zhong)央熱(re)(re)水(shui)(shui)(shui)器(qi)內部結構主要(yao)由四個核心(xin)部件:壓(ya)縮機,冷凝器(qi),膨脹(zhang)閥,蒸(zheng)(zheng)(zheng)發(fa)器(qi)組成。中(zhong)央熱(re)(re)水(shui)(shui)(shui)器(qi)的(de)(de)(de)工作流程(cheng)是這(zhe)樣的(de)(de)(de):壓(ya)縮機將回流的(de)(de)(de)低壓(ya)冷媒(mei)壓(ya)縮后,變(bian)(bian)成高(gao)溫(wen)(wen)高(gao)壓(ya)的(de)(de)(de)氣體排(pai)出,高(gao)溫(wen)(wen)高(gao)壓(ya)的(de)(de)(de)熱(re)(re)媒(mei)氣體流經(jing)纏繞在水(shui)(shui)(shui)箱(xiang)外面的(de)(de)(de)銅管(guan),熱(re)(re)量經(jing)銅管(guan)傳導(dao)到(dao)水(shui)(shui)(shui)箱(xiang)內,冷卻下來(lai)的(de)(de)(de)冷媒(mei)在壓(ya)力的(de)(de)(de)持續作用(yong)下變(bian)(bian)成液(ye)態,經(jing)膨脹(zhang)閥后進入蒸(zheng)(zheng)(zheng)發(fa)器(qi),由于蒸(zheng)(zheng)(zheng)發(fa)器(qi)的(de)(de)(de)壓(ya)力驟然降(jiang)低,因此液(ye)態的(de)(de)(de)冷媒(mei)在此迅速(su)蒸(zheng)(zheng)(zheng)發(fa)變(bian)(bian)成氣態,并吸(xi)收(shou)(shou)大量的(de)(de)(de)熱(re)(re)量。同時,在風扇(shan)的(de)(de)(de)作用(yong)下,大量的(de)(de)(de)空(kong)氣流過蒸(zheng)(zheng)(zheng)發(fa)器(qi)外表面,空(kong)氣中(zhong)的(de)(de)(de)能(neng)量被(bei)蒸(zheng)(zheng)(zheng)發(fa)器(qi)吸(xi)收(shou)(shou),空(kong)氣溫(wen)(wen)度迅速(su)降(jiang)低,變(bian)(bian)成冷氣排(pai)進廚房。隨后吸(xi)收(shou)(shou)了(le)一(yi)定能(neng)量的(de)(de)(de)冷媒(mei)回流到(dao)壓(ya)縮機,進入下一(yi)個循環。
