【英文篇名】 Control schemes for heat metering of outdoor piping in heating systems and their analysis 【作者中文名】 邹瑜; 徐伟; 黄维; 【作者英文名】 By Zou Yu; Xu Wei and Huang Wei; 【作者单位】 中国建筑科学研究院空气调节研究所; 【文献出处】 暖通空调, HV 室外供热系统; 控制方式; 【英文关键词】 heat metering; outdoor heating system; controlling scheme; 【摘要】 针对可热计量的两种室内供热系统，在计算分析的基础上认为，对于采用集中式热力站的系统，在用户入口处，单管跨越式系统应加流量限制器，双管系统应设差压控制器；对于采用分散式热力站的供热系统，单管跨越式系统可不设流量限制器，双管系统二次侧宜采用循环水泵变频调速控制，不宜加差压控制器。 【英文摘要】 In accordance with the two different indoor heating systems, puts forward the control schemes of the outdoor heating system on the basis of calculation and analysis. Holds that for central substation system, at the inlet of the heat users, the flow controller(self acting)should be used to keep the flow rate constant in the single pipe cross over heating system and the differential pressure controller(self acting)should be used to keep the pressure drop constant in two pipe heating system and that for t...
