摘要
常规的供热系统质调节模式未能充分考虑人员、灯光、设备散热及邻室传热等热扰量,也未反映出建筑围护结构热惯性作用下各热扰量对室温影响的衰减和延迟特性,从而导致室温控制不精确.因此,提出基于加权扰量的供热系统质调节运行模式的构建方法,并将此与常规质调节模式的运行效果进行比较.结果表明,相较于常规质调节模式,基于加权扰量的质调节模式在供水温度、供暖小时数和室温稳定性方面都表现出明显的优势,该模式不仅可显著降低供热系统的运行能耗,提升能源应用效率,而且还可增强室内温度的稳定性,进一步提高居住者的热环境舒适度.因此,基于加权扰量的质调节模式为供热系统的运行调节提供了一种新的有效路径.
Abstract
Conventional heating system quality regulation mode fails to fully consider the occupants,lighting,equipment heat dissipation and neighboring rooms heat transfer and other thermal disturbances,and does not reflect the building envelope thermal inertia of the thermal disturbances under the effect of the attenuation and delay characteristics of the impact of the indoor temperature,which leads to inaccurate indoor temperature control.In this paper,we propose a method for constructing a weighted disturbance-based quality regulation mode for the heating system,and compare the operation effect of this mode with that of the conventional quality regulation mode.The results show that compared with the conventional quality regulation mode,the weighted disturbance-based quality regulation mode shows obvious advantages in water supply temperature,heating hours and room temperature stability,which not only significantly reduces the energy consumption of the heating system and improves the energy efficiency,but also enhances the stability of the indoor temperature and further improves occupants'thermal comfort in thermal environment.Therefore,the weighted disturbance-based quality regulation mode provide an effective new path for the operation of the heating system.
