Analysis of weighted disturbance-based quality regulation mode of heating systems
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.
