摘　　要：对青岛市某购物中心间接连接供热系统的运行数据进行节能诊断分析。针对系统存在的供热量与所需热负荷不匹配的问题,建立系统热平衡数学模型及TRNSYS仿真模型。仿真模型TRNSYS与计算数学模型的计算室温与耗热量误差控制在1.5%以内,优化控制算法为水泵根据气候补偿变频。所提出的基于室外温度变化的建筑供热节能控制算法是采用气候补偿实现动态变频调节的,通过调节系统一次侧循环水泵的流量,改变二次侧供水温度,更好地适应由于室外温度不同造成的建筑热负荷不同。结果表明一周内优化控制带来的用能减少量为7.2%,供暖季内优化控制策略带来总用能量减少16.2%,其中营业期节能量减少26.0%,非营业期减少5.4%。Energy-saving diagnosis and analysis are carried out on the operation data of the indirect heating system in a shopping center in Qingdao.Based on the data diagnosis of the incompatible performance of the required heat load and the heating capacity,a mathematical model of the heat balance system and a TRNSYS simulation model are established to optimize the control algorithm by associating water pump frequency conversion to the climate compensation.The stability error between the room temperature and heat consumption of the simulation model TRNSYS and the computational mathematical model is controlled within 1.5%.A dynamic frequency conversion adjustment is proposed to adjust the flow rate of the primary circulating water pump with climate compensation,so as to change the temperature of the water supply on the secondary side and to better adapt to different heat loads of buildings caused by various outdoor temperatures.Results show that the energy consumption reduction within a week is 7.2%,and the optimal control strategy in the heating season reduces the total energy consumption by 16.2%,of which the energy saving during the business period is reduced by 26.0% and the non-business period is reduced by 5.4%.
