? ?專家公寓小區長期以來一直采用汽——水換熱模式,即以蒸汽為熱媒的供熱方式,但考慮到開發區西區蒸汽生產實現“煤改氣”后,蒸汽生產成本大幅攀升,同時蒸汽輸送過程中穩定性較差、管網能耗損失大等原因,為提高供熱運行安全和供熱質量,提高經濟效益和社會效益,經公司研究,決定對專家公寓小區供熱方式進行改造,由原來的汽——水換熱模式,改為水——水換熱模式。

? ?為保障供熱安全穩定,經過技術人員的現場勘查和充分論證,確定了雙熱源系統的方案,即:在保留原有汽——水換熱模式的基礎上,新建水——水換熱系統的移動式換熱站,從長江中道一次網接入配套管網。工程建設自10月初開始施工,采用直埋與架空相結合的方式敷設,總長度共375m。在管網鋪設過程中,公司嚴把工程質量關,科學安排,加快施工進度,保證施工安全。10月底專家公寓小區一次網管網敷設順利完工,11月3—4日,該小區完成移動式換熱站整套機組設備安裝、調試工作,實現雙熱源切換。
