摘要(Abstract):
针对上海地区某一商务楼及其空调系统进行了仿真试验,对系统正常启动和提前启动两种控制策略的仿真结果进行了比较。结果表明,根据气象条件和建筑物的特性适时地提前启动系统,通过利用建筑物热容的能量储存能力可以减小系统的峰值电力需求,降低系统的运行费用同时室内的热舒适性状况未受影响。
An office building in Shanghai is tested with two operation strategies of normal and pre-cooling respectively.The results show that the capacity of building can be used for energy storage.The strategy of suitable pre-cooling schedule based on outdoor conditions and building capacity can reduce the power demand on peak hour and maintain acceptable indoor thermal comfort,and it result in operation cost saving.
