摘要 在目标建筑室外工况和负荷工况处于长期变化的基础上,从云平台硬件系统和软件系统的构建入手,给出了基于云平台技术的能效管理系统的设计方案。通过对能效管理模型的优化提出双源热泵系统最佳运行方案。与常规出水温度设定运行方案对比发现,在夏季31℃工况下,优化前后空调系统运行冷源能效比之差的平均值约为0.42,可平均节约能耗10.2%;在冬季5℃工况下,优化前后空调系统运行热源能效比之差的平均值约为0.33,可平均节约能耗7.1%。 Based on the long-term changes of the external working conditions and load conditions of the target building,the design scheme of the energy efficiency management system is presented from the construction of hardware and software systems of cloud platform.The optimized operation plan of the dual source heat pump system is proposed by optimization on energy efficiency management model.Compared with the conventional operation plan based on outlet temperature,it is found that,under the condition of 31℃in summer,the average difference between the cooling source energy efficiency ratios of the air conditioning system before and after optimization is about 0.42,which can save energy consumption by 10.2%on average.Under the condition of 5℃in winter,the average difference between the heat energy efficiency ratios before and after optimizing the air conditioning systemis about 0.33,which can save energy consumption by 7.1%on average.
