摘要:
为有效把握我国寒冷地区绿色公共建筑运行能耗特征及运行能效水平,以天津生态城公屋展示中心为研究对象,通过运营阶段实时监测数据,掌握案例建筑能耗结构、不同季度各分项能耗分布、系统季节能效系数、热泵机组能效系数、循环水泵输送系数等能耗指标,并从机组的启停时序及供回水温差两方面优化案例建筑运行,分析其节能潜力.分析整理实时监测数据可知,采暖季建筑能耗占全年能耗比例最大达 63% ,此时段建筑耗电量达 77% ;热泵系统夏季能效比为 5 .77,冬季能效比为 3 .53;冷冻水循环水泵冬季输送系数为 35 .29、夏季输送系数为 58 .85;利用模拟工具对采用优化方案后建筑运行能耗进行运行效果分析可知,控制机组启停时序总能耗降低 27 .2%,在此基础上提高系统供回水温差总能耗可降低 30 .8%
Abstract:
In order to effectively grasp the energy consumption characteristics and operational energy efficiency of green public buildings in cold areas of China, this paper takes the Tianjin Eco -City Public Housing Exhibition Center as the research object, realizes the data through the operation phase, controls the energy consumption structure of the case building, energy consumption distribution, energy efficiency coefficient of the system, energy efficiency coefficient of the heat pump unit, and the transport coefficient of the circulating water pump, to optimize the case building operation from the aspects of the start and stop timing of the unit and the supply and return temperature. Through analysis and finishing real -time monitoring data it can be seen that the energy consumption of the building season accounted for the largest annual energy consumption up to 63%, with electricity consumption of 77% at the time. Heat pump system summer energy efficiency ratio of 5.77, and winter energy efficiency ratio of 3 .53. The winter transmission coefficient of the chilled water circulating pump is 35 .29 and the summer transmission coefficient is 58.85. The simulation results show that total energy consumption of the control unit is reduced by 27 .2%, and the system is provided on the basis of the simulation tool. The total energy consumption of the water temperature difference can be reduced by 30 .8%
