一、问题的提出 热水采暖系统热负荷的调节,通常是在热源(锅炉房)处进行集中调节的。集中调节的方式主要有:改变网路送水温度的质调节,改变网路循环水量的量调节,改变供热时数的间歇调节。集中调节广泛应用于热水采暖系统,通过调节可以适应室外气温的变化,避免整个采暖系统室温过高或过低,但集中调节满足不了不同热用户的放热特性,不能解决热用户之间热负荷分配不平衡所引起的冷热不均的问题。
I. Proposal of the problem The adjustment of the thermal load of the hot water heating system is usually conducted at the heat source (boiler room). The methods of centralized adjustment mainly include: changing the quality of the water supply network, adjusting the amount of circulating water, and changing the intermittent adjustment of the heating hours. The centralized adjustment is widely used in the hot water heating system, and can be adjusted to adapt to changes in the outdoor air temperature to avoid the entire heating system room temperature being too high or too low, but the centralized adjustment cannot satisfy the heat release characteristics of different heat users and cannot solve the heat between the hot users. Unbalanced cooling and heating caused by unbalanced load distribution.
