摘要 

提出了办公建筑中央空调最优起动时间的计算方法。从空调的历史能耗曲线出发,把空调运行划分为起动、恒温两个阶段,分析空调的两阶段能耗,结合地区峰谷平分时电价,采用迭代方法计算空调最优开起时间。通过现场数据模拟计算,验证了该计算模型与方法的有效性,可对办公类型的中央空调起动时间做出准确计算,最后结合现场数据探讨了节能和经济性的关系,给出了该方法的应用范围。算例表明该方法无需对空调设备硬件和软件进行改造,具有显著经济性和实用性。

Abstract

A calculating method on optimal starting time of central air conditioners in building is proposed. First, the operation of air conditioners can be divided into two stages based on the historical energy consumption curve. Second, the second-stage energy consumption of air conditioner is analyzed, and a calculating method of optimal starting time is given based on TOU power price. Third, the method is tested and validated through onsite simulation, and the optimal starting time can be accurately calculated with this method. Finally, the relationship between energy saving and economy is studied, and the application scope of the method is presented. The test case shows that the method has significant economic and practical benefits to the enterprise without any transformation to air conditioner’s hardware and software.
