某空调系统运行参数的遗传算法优化

摘要

空调系统能耗占建筑能耗的50%以上,减少空调系统能耗可在一定程度上降低建筑能耗。以宁波市某办公建筑的空调系统为研究对象,对空调系统各设备建立基于功率的能耗模型,并用实数编码遗传算法对典型日空调系统的冷水供水温度、冷水流量和冷凝侧风量进行求解,得出了适合于该建筑的节能运行策略。研究结果表明,优化后空调系统全天总能耗为1578.86kW,比优化前该系统日平均能耗(1819.70kW)节能13.24%。%Energy consumption of air conditioning system accounts for more than 50% of building energy consumption. Reduc-ing the energy consumption of air conditioning system can reduce building energy consumption. The air conditioning system of an office building in Ningbo City is chosen as the research object and the power model of each componentis built. Then real-coding genetic algorithm method is usedto solvethe chilled water supply temperature,chilled water flow rate and condensation side air vol-ume of the air conditioning systemon a typical day. Research results show thatafteroptimized,the total energy consumption of this air conditioning system is 1578. 86kW,which is 13. 24 percent less than the average energy consumption (1819. 70kW)before op-timization.
