1. 熱(re)水伴熱(re)系(xi)統（圖13.2）

 2. 蒸汽伴熱系統（圖13.3）

  ②. 蒸汽(qi)伴(ban)熱系統分配站。

   配管(guan)設計見圖13.4。蒸(zheng)(zheng)(zheng)汽(qi)(qi)分(fen)配站(zhan)安裝位置高(gao)于蒸(zheng)(zheng)(zheng)汽(qi)(qi)總(zong)(zong)管(guan)時(shi)，分(fen)配站(zhan)低(di)點(dian)可(ke)(ke)不設排放冷凝水(shui)的蒸(zheng)(zheng)(zheng)汽(qi)(qi)疏(shu)水(shui)閥系統，水(shui)平安裝的分(fen)配站(zhan)應(ying)無袋形并(bing)坡向蒸(zheng)(zheng)(zheng)汽(qi)(qi)總(zong)(zong)管(guan)。蒸(zheng)(zheng)(zheng)汽(qi)(qi)分(fen)配站(zhan)低(di)于蒸(zheng)(zheng)(zheng)汽(qi)(qi)總(zong)(zong)管(guan)時(shi)，其上游不得(de)有(you)下凹的袋形彎，分(fen)配站(zhan)的低(di)點(dian)應(ying)設蒸(zheng)(zheng)(zheng)汽(qi)(qi)疏(shu)水(shui)閥組。蒸(zheng)(zheng)(zheng)汽(qi)(qi)分(fen)配站(zhan)至少有(you)3根伴(ban)管(guan)（DN15）送至半(ban)徑為3m范(fan)圍內的地點(dian)時(shi)才設置，否(fou)則伴(ban)熱供(gong)汽(qi)(qi)管(guan)可(ke)(ke)直(zhi)接(jie)從(cong)蒸(zheng)(zheng)(zheng)汽(qi)(qi)總(zong)(zong)管(guan)上引出。分(fen)配站(zhan)應(ying)布(bu)置在不妨礙通行、便于操(cao)作的地方，布(bu)置應(ying)考慮整(zheng)齊(qi)和美(mei)觀(guan)。供(gong)汽(qi)(qi)管(guan)的閥門應(ying)布(bu)置在便于接(jie)近的地方。分(fen)配站(zhan)的蒸(zheng)(zheng)(zheng)汽(qi)(qi)應(ying)從(cong)蒸(zheng)(zheng)(zheng)汽(qi)(qi)總(zong)(zong)管(guan)的頂部(bu)引出。

  ③. 蒸汽伴(ban)熱(re)系統冷(leng)(leng)(leng)凝(ning)(ning)(ning)水(shui)(shui)(shui)回(hui)(hui)(hui)收(shou)(shou)時，收(shou)(shou)集(ji)站(zhan)和冷(leng)(leng)(leng)凝(ning)(ning)(ning)水(shui)(shui)(shui)回(hui)(hui)(hui)收(shou)(shou)管(guan)的(de)(de)(de)布(bu)置(zhi)，見圖13.5。冷(leng)(leng)(leng)凝(ning)(ning)(ning)水(shui)(shui)(shui)收(shou)(shou)集(ji)站(zhan)高于冷(leng)(leng)(leng)凝(ning)(ning)(ning)水(shui)(shui)(shui)總管(guan)時，低點可不設排(pai)液口；回(hui)(hui)(hui)水(shui)(shui)(shui)管(guan)應無袋形(xing)并(bing)坡(po)向冷(leng)(leng)(leng)凝(ning)(ning)(ning)水(shui)(shui)(shui)總管(guan)。冷(leng)(leng)(leng)凝(ning)(ning)(ning)水(shui)(shui)(shui)收(shou)(shou)集(ji)站(zhan)至(zhi)少有3根(gen)冷(leng)(leng)(leng)凝(ning)(ning)(ning)水(shui)(shui)(shui)支(zhi)管(guan)時才設置(zhi)，否則可直接接至(zhi)冷(leng)(leng)(leng)凝(ning)(ning)(ning)水(shui)(shui)(shui)總管(guan)上。冷(leng)(leng)(leng)凝(ning)(ning)(ning)水(shui)(shui)(shui)收(shou)(shou)集(ji)站(zhan)應布(bu)置(zhi)在(zai)不妨礙通(tong)行(xing)，便(bian)于操作的(de)(de)(de)地方(fang)，布(bu)置(zhi)應考慮整齊和美觀。冷(leng)(leng)(leng)凝(ning)(ning)(ning)水(shui)(shui)(shui)回(hui)(hui)(hui)水(shui)(shui)(shui)管(guan)的(de)(de)(de)閥門應布(bu)置(zhi)在(zai)便(bian)于接近的(de)(de)(de)地方(fang)。冷(leng)(leng)(leng)凝(ning)(ning)(ning)水(shui)(shui)(shui)回(hui)(hui)(hui)水(shui)(shui)(shui)管(guan)應從(cong)冷(leng)(leng)(leng)凝(ning)(ning)(ning)水(shui)(shui)(shui)總管(guan)的(de)(de)(de)頂(ding)部引入。

  ④. 蒸汽伴熱系統(tong)冷凝(ning)水(shui)不回(hui)收時(shi)，收集站(zhan)和冷凝(ning)水(shui)回(hui)收管的布置，見圖13.6。
