开式热水供暖系统运行问题及其改进

Operating problems of a heating system and improving measures

分析了某热水供暖系统不能正常运行的原因，介绍了针对性改进措施。改造结果表明，当循环泵高于所有热用户时，只要设计、施工合理，系统不但能正常运行，而且还能连续地、最大限度地析出水中空气，保证循环水泵稳定运转。

Discusses the causes for poor operation of an open hot water heating system and adequate measures adopted. The result shows that for proper design and construction the heating system works well even though the circulating pump is positioned higher than all heat terminals, and most air within the system can be vented, and the circulating pump runs more steadily.
