摘要:
随着城市化进程的加快和人民生活质量的改善,建筑耗能比例大幅上升,开展居住节能建筑热负荷数值分析,可有效地节约能源与成本,并为居住建筑后续的采暖设计提供理论依据。文章以济南村镇小型别墅为例,基于传统稳态热负荷与逐时热负荷理论,采用建筑动态负荷计算软件DEST,对节能75%的建筑进行热负荷计算,并对2种热负荷之间的联系与对应能耗进行分析,研究了逐时热负荷计算中异常负荷出现的原因。结果表明:实际采暖季中,逐时热负荷值要比同百分比的稳态的高20 %~30 %;采用逐时热负荷后,采暖季的建筑总能耗比传统的稳态能耗减少了20%;实际工程中,室内外热扰较多,需要加强对室内温度的实时监测与控制,将逐时控制理论应用于模拟计算与调控设备运行中。在后期的设备运行方面,逐时热负荷更具参考价值。
Abstract:
With the acceleration of urbanization and the improvement of peoples living quality, the proportion of building energy consumption in our country has risen sharply, and umerical analysis of thermal load of residential energysaving buildings can save energy and cost effectively and provide theoretical basis for subsequent heating design of residential buildings. The paper has completed the calculation of steady-state heating load and the simulation of hourly heating load of 75% energysaving building by establishing the model and building energy consumption simulation software DEST. By calculating the heating loads of the building which is energy saving 75%, the relationship between the steady-state heating load and the hourly heating load has been discussed, and the reason for the abnormal load in the load operation has been analyzed. The result shows in actual heating season, the load value of different percentage is 20 %~30 % higher than the same proportion as the base of steady-state heating load. This shows that the hourly heating load is more valuable in terms of the equipment operation, and the load value should be calculated and analyzed. The total energy consumption in the heating season is 20% lower than the traditional steady state energy consumption by using hourly heating load. In actual engineering, there is a lot of heating disturbances indoor and outdoor, and the realtime monitoring and controlling the indoor temperature should be strengthened. The concept of hourly control should be applied to the operation of analog computing and regulatory equipment.
