多源聯網式輸配供冷系統能耗研究
Research on energy consumption of multi-source networked transmission and distribution cooling system
摘要:
區域供冷目前主要存在集中式輸配和分布式輸配2種形式,總體多數以集中能源站、大管道、長距離輸配為特征,導致輸配能耗高、低負荷工況經濟性差等問題。針對以上問題,本文提出了多源聯網式輸配供冷系統,各用戶端分建能源站(多源),通過管網連接各能源站,實現在中低負荷期各用戶能源自給自足,峰值負荷期由其他能源站(多源)補充。通過案例計算了集中式輸配系統、分布式輸配系統、多源聯網式輸配系統的輸配能耗,結果表明,多源聯網式輸配系統比集中式輸配系統節能41%,比分布式輸配系統節能23%。
Abstract:
At present, there are mainly two forms of district cooling: centralized transmission and distribution and distributed transmission and distribution. Generally, most of them are characterized by centralized energy stations, large pipelines and long-distance transmission and distribution, leading to high energy consumption and poor economy under low load conditions. In view of the above problems, this paper proposes a multi-source networked transmission and distribution cooling system, in which each user builds energy stations separately (multi-source) and connects each energy station through a pipeline network, so as to achieve energy self-sufficiency for each user during the medium and low load periods, and be supplemented by other energy stations (multi-source) during the peak load period. By calculating the energy consumption of centralized transmission and distribution system, distributed transmission and distribution system, and multi-source networked transmission and distribution system, the results show that the multi-source networked transmission and distribution system saves 41% energy compared to the centralized transmission and distribution system, and 23% energy compared to the distributed transmission and distribution system.
