基于热舒适度的办公建筑HVAC系统节能控制

Energy-Saving Control of Office Building HVAC System Based on Thermal Comfort

建筑节能控制是一个满足舒适需求条件下的多目标优化问题,然而对于缺失运行数据的新建建筑,如何控制供暖、通风和空调(HVAC)系统达到既舒适又节能的效果是一个控制难题.针对这个问题,本文首先建立了新建建筑空间模型,然后对该模型进行能耗仿真分析,在此基础上,提出基于人员热舒适度的模糊控制算法,得出最优控制区间,从而在较低能耗水平情况下获得更长的热舒适天数,达到既节能又舒适的目标.基于人员热舒适度的节能控制对建筑HVAC系统绿色运行具有促进作用.

Building energy-saving control is a multi-objective optimization problem considering the comfort demand.However,for the new buildings lacking operation data,it is a real conundrum to control the Heating,Ventilation and Air-Conditioning(HVAC)system to achieve both comfort and energy-saving.Aiming at this problem,this study first builds the space model of new buildings and then carries out simulation of energy consumption on the model.On this basis,it puts forward a fuzzy control algorithm based on thermal comfort of personnel to determine the optimal operation interval.Therefore,longer days of thermal comfort are enabled under the condition of lower energy consumption,achieving the goal of both energy saving and comfort.The energy-saving control based on the thermal comfort of personnel can promote the green operation of HVAC systems in buildings.
