Therefore, this conclusion should be taken into account when we study how to select one circulation pump with reason in a hot-water supplysystem.
管段流量与终点水温的关系，是热水供应系统中循环泵选择计算研究的一个重要理论依据。

Taking the thermodynamic system of radiator testing stand as a controlled object, studies the fuzzy control process of rule self-tuning for supply air temperature in air circulation systems.
The safety design of gas supplysystem, hot water circulation system, alarm system and so on in atmospheric gas hot-water heating boiler room is discussed.
