多源联网式输配供冷系统能耗研究
Research on energy consumption of multi-source networked transmission and distribution cooling system
摘要：
区域供冷目前主要存在集中式输配和分布式输配2种形式，总体多数以集中能源站、大管道、长距离输配为特征，导致输配能耗高、低负荷工况经济性差等问题。针对以上问题，本文提出了多源联网式输配供冷系统，各用户端分建能源站（多源），通过管网连接各能源站，实现在中低负荷期各用户能源自给自足，峰值负荷期由其他能源站（多源）补充。通过案例计算了集中式输配系统、分布式输配系统、多源联网式输配系统的输配能耗，结果表明，多源联网式输配系统比集中式输配系统节能41%，比分布式输配系统节能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.
