老式的供暖系统常常出现供暖效果与设计状态相差很远的结果，而采用自力式流量控制阀和自动恒温控制阀后，在很大程度上解决了供暖系统水力失调的问题从而提高了供暖的质量。本文针对双热源热水供暖系统的工况特点，以节能降耗为基点，从热源至热用户室内系统这个整体进行阐述整个热源系统、外管网系统、用户系统的平衡调节特性、方式，对老建筑供暖系统的室内系统提出了改造建议，同时对系统进行综合性调节，最终实现优质低耗供暖的目的。%The old heating system often has the effect that heating effect and design state are quite different. After the use of self-operated flow control valve and automatic temperature control valve, the hydraulic imbalance problem is solved to a great extent, so as to improve the heating quality. According to the characteristics of hot water heating system with double heat source, starting to reduce the energy consumption, this paper describes the balance regulation characteristics and mode of the whole heat source system, outdoor pipe system and users system from the heat source to the user indoor system, proposes the reform proposals, at the same time conducts comprehensive regulation, and finally achieves the purpose of improving the heating quality.
