区域供冷管网系统中冷损耗分析与计算

The Analysis and Calculation of Cold Loss in District Cooling Pipe Network System

区域供冷不仅集中了冷却塔的布置,美化了供冷园区的环境,同时还由于各座建筑物空调峰值负荷出现的时间段不同,减少了装机容量,节省了初投资。由于区域供冷需建立供冷管网,管网冷损耗至今仍是许多设计师对应用区域供冷心存疑虑的地方,本文利用fl uent软件,对北京某区域供冷项目的管网冷损耗进行了数值模拟,并对模拟结果进行了分析。

District cooling not only assembling the cooling towers and beautifing the environment of cooling park.but also reducing the capacity and saving the initial investment, due to the difference of each building＇s peak load to appear. However, the district cooling need to establish a cooling pipe network, the cold loss of the pipe network is still misgiving to use district cooling for many designers.This paper uses fluent software to simulate the pipe network＇s cold loss of a district cooling project in Beijing, and analyses the simulation results.
