本论文是在目前现有的集中供暖调节方法基础上进行的,研究了集中供暖系统在
室温调节下的供暖负荷和流量的特性,提出了质调节下量调节的供暖调节方法。质调
节下量调节的供暖系统,根据各种类型建筑物由于自身使用功能的不同,在一天内0:
00~24:00中每一个时间段所需供暖量不同,对集中供暖区域中不同的建筑物进行供
暖分区,并对一天中的时间段作出合理划分;在每个时间段对各个不同分区内的建筑
物进行统计,计算出各个供暖分区在每个时间段的供暖负荷。根据统计的数据,在集
中热源处(锅炉房)进行质调节,对不连续使用的供暖分区进行量调节,这样不仅可
节约供暖能量,而且可以节约热网循环水泵的耗电量,即可达到节热节电的双重效果。
本论文对质调节下量调节供暖调节方法建立了数学模型,并在实验台上进行了水
力工况的模拟,绘制了供暖运行调节曲线;结合实际工程阐述了质调节下量调节规划
的步骤以及能耗分析方法,编制了供暖运行策略。
本论文对某一示例工程进行质调节下量调节应用举例,该示例质调节下量调节供
暖系统中以办公楼等办公用建筑为代表的供暖分区年耗热量节约百分比为 %;
对其整个可调区进行统计,年耗热量节约百分比为 %;由此可见,对于校园供
暖系统,采用质调节下量调节供暖调节方法具有很好的节能性。

Abstract
Based on the extant regulating methods of district central heating system, the paper
studies the characteristic of heat load and flux of heating system when the
room-temperature is adjusted, and put forward a new method special for district central
heating system which is called “Fluxregulation Under Thermoregulation (FUT)”.
According to each kind of type building as a result of own use function difference, in a day
0:00~24:00 of each partment different needs of the heat load, The FUT heating
system divides all the buildings into several regions, and makes the reasonable time
compartment division to a day. In each time the FUT heating system carries on the
statistics to each different district buildings'heat load. According to data which has been
counted, in the centralized heat source place the FUT system carries on the
thermoregulation, and carries on the fluxregulation to the intermittent usage heating district,
which not only save the heating energy, moreover reduce the power consumption of the
circulating water pump.
The paper has established the mathematical model of FUT, and has carried it on the
water power operating mode simulation in the laboratory bench, and has drawn up the
heating movement regulating curve. Unified the actual project this paper has elaborated
FUT plan step as well as the energy consumption analysis me
