摘　　要：探讨基于全年逐时负荷计算下纺织空调PLC自控系统的节能效果。夏季、过渡季节车间逐时负荷由室外空气空调计算逐时综合温度,冬季逐时负荷根据室外温度计算。在全年逐时负荷基础上计算出车间全年逐时送风量,对风机运行频率进行变频调节,利用PLC步进算法对循环水泵变频调节,并结合新风窗比例控制算法合理利用室外新风。系统在徐州某纺织车间运行稳定,车间温度误差控制在±0.7℃,相对湿度误差控制在3%以内,平均节电率在6.36%。该系统对纺织车间温湿度控制精度较高,节能效果显著,实际应用价值较大。This article discusses the energy-saving effect of the textile air-conditioning PLC automatic control system based on the hourly load calculation throughout the year.The hourly load of the workshop in summer and transition seasons was calculated by the outdoor air conditioner and the hourly integrated temperature was calculated.The hourly load in winter was calculated according to the outdoor temperature.Based on the hourly load of the whole year,the hourly air output of the workshop throughout the year was calculated for variable frequency regulation of the fan operation frequency.The PLC stepping algorithm was used to adjust the frequency of the circulating water pump,and the proportional control algorithm of new wind window was combined to rationally utilize the outdoor fresh air.The system was running stably in a textile workshop in Xuzhou.The temperature error of the workshop was controlled within±0.7℃.The relative humidity error was controlled within 3%,and the average power saving rate was 6.36%.Therefore,it is believed that the system has high precision in temperature and humidity control in the textile workshop,significant energy saving effect,and great practical application value.
