基于精准按需供能的中央空调开机调度研究

Research on central air conditioning start-up scheduling based on accurate energy supply according to the demand

为满足企业节能降耗要求,解决生产车间中央空调开机调度问题,提出一种基于精准按需供能的调度方法。为获取中央空调系统的运作信息,通过分析不同季节的空调机理总结出运行工况,获取空调机组的运行参数,使用温湿度采集器采集数据,并利用加权平均计算出不同区域的温湿度。针对机器设备故障和温湿度变化两种扰动因素,采用双反馈机制重调度策略并设置预留安全值。为解决具有动态联动关系的空调机组调度问题,以调控时间和能源损耗为优化目标函数,构建以精准按需供能的调度模型。相比于原调度方法,该调度模型时间效率提升了22.08%,能源损耗降低了16.7%。

In order to solve the start-up scheduling problem of central air conditioning in production workshops and meet the requirements of energy saving and consumption reduction in enterprises,a scheduling method based on precise energy supply is proposed.In order to acquire the operation information of the central air conditioning system,the operating conditions are summarized by analyzing the air conditioning mechanism in different seasons,and the operating parameters of the air conditioning unit are obtained.The temperature and humidity collector is used to collect data,and the temperature and humidity information of different regions is calculated by weighted average.The rescheduling strategy is proposed and the reserved safety value is set according to the two disturbance factors such as machine and equipment failure and temperature and humidity change.In order to solve the scheduling problem of air conditioning units with dynamic linkage relationship,a scheduling model with accurate energy supply according to the demand is constructed.The objective function of optimization is control time and energy loss.Compared with the original scheduling method,the scheduling model improves the time efficiency by 22.08%and reduces the energy consumption by 16.7%.
