Based on the characteristics of one-pipe-series-loop heating system,the individual metering charge using heat-time meter for one-pipe-series-loop heating system is presented.
针对垂直单管式供暖系统的特点,提出采用热时表实现垂直单管式供暖系统分户计量收费。
The thesis analyses the degree of hydraulic misad justment caused by users adjustment through simulation calculation under the condition of the steady pressure difference or the steady flow in the single pipe cross-over heating system, and discusses the merit and the demerit of two control schemes.
通过对单管跨越式供暖系统在定压差、定流量条件下的模拟计算,分析了两种情况下用户行为调节产生的系统水力失调度,讨论了两种控制方法的优缺点。
Considers that this device can make the cost lower and the effect better, and it is suitable for reform of heat metering on old single-pipe series-loop heating systems.
介绍了管道测量式热分配表的研制背景、计量原理、热量分摊计算方法、结构以及应用情况 ,认为这种装置成本低、效果好 ,适合于原有单管顺流式供暖系统的热计量改
Analyses three projects that the differential pressure controllers are used in two-pipe heating systems with household heat metering,recommends some selective principles of three projects,points out that gravity head may not be considered when hydraulic calculation is operated in the design condition,and two-pipe heating systems with household heat metering should be the direct-return system.
对压差控制阀在分户计量双管供暖系统中的三个应用方案进行了分析 ,给出了各方案的选择原则 ,并指出分户计量双管供暖系统在设计工况下进行水力计算时 ,自然作用压头可以不予考虑 ,户内和户外系统应采用异程式。
