【摘要】：在北方采暖地区,散热器采暖系统在早期建筑中有着广泛的应用,而近年来由于地板辐射采暖系统应用规模的扩大,在同一换热站内存在两种末端供热系统的情况越来越普遍。由于在同一热源中,两种系统存在不同的运行参数,造成用热矛盾。低温地板辐射采暖系统热用户以相对较高的运行温度供热,造成多余的热量消耗。本文从这一用热矛盾情况出发,首先阐述了国内外对于集中供热节能研究与混水系统研究的现状,并提出针对该混合系统几种可行的系统节能运行方式,分析各种运行方式的优缺点,说明本课题研究所选用的混水泵系统的合理性。阐述实验运行原理,并通过系统方案的确定、各设备选型确定实验模型。对冬季供热情况进行模拟运行,对比混水泵引入前后的室内温度变化情况。通过分析得出,针对混合系统启用混水泵后,地板辐射采暖系统既保证室内设计温度要求,又达到节能的目的。并通过分析温度补偿曲线设定值与实际值偏差,为工程应用提供理论指导。以吉林省白山市存在混合系统的换热站进行混水系统应用设计,根据现场实际情况提出设计方案。对设计后系统运行时的供热混合比进行分析,得出室外温度与供热混合比呈现相同的变化规律,且在室外温度偏高时,混水系统有着更高的节能效率。通过对混水设计前后地板辐射采暖系统运行的能耗对比,以及采用混水系统后地板辐射采暖系统与散热器采暖系统的单位面积能耗对比,得出在引入混水系统后,混合系统的运行能耗得到有效降低的结论。
[Abstract]:In the North heating area, radiator heating system has been used widely in the early construction, but in recent years due to the expansion of the scale of the application of radiant floor heating system, heat transfer station in the same memory in two at the end of the heating system has become increasingly common. Because in the same heat source, there are two kinds of different operation parameters system that caused by paradoxical heat. The low-temperature radiant floor heating system heat users with relatively high operating temperature of heating, causing excess heat consumption. This paper from this starting with hot contradiction situation at home and abroad are described. Firstly, the research status for energy research and mixing water system of central heating system, and puts forward several feasible energy-saving operation mode the hybrid system, analyzing the advantages and disadvantages of various modes of operation, reasonable mixing pump system of this subject selected. Introduces the operation principle, and through the system The case is determined, each equipment selection determine the experimental model. Simulate the operation of the winter heating, indoor temperature changes before and after mixing pump was introduced. Through the analysis, the hybrid system enabled mixing pump, both to ensure the indoor design temperature of radiant floor heating system, and achieve the purpose of saving energy. And through the analysis of temperature the compensation curve set value and the actual value deviation, to provide theoretical guidance for the engineering application. In Jilin Province, Baishan City heat exchange station is designed mixed hybrid systems, puts forward the design scheme according to the actual situation of the scene. After the design of hybrid heating system runtime analysis, obtains the variation of outdoor temperature mixing and heating than the same and, when the outdoor temperature is too high, the mixing system has higher energy efficiency. Through the operation of the water heating system design before and after the floor radiation The energy consumption comparison, and the mixing system of radiant floor heating system and radiator heating system energy consumption per unit area comparison, obtained in the introduction of mixed water system, energy consumption of hybrid system to effectively reduce the conclusion.
