Description

纺织厂空调节能方法
技术领域
本发明涉及一种纺织厂空调节能方法，属于纺织节能技术领域。
背景技术
目前，纺织厂生产过程中需要用到各种各样的空调进行冷却，如果使用不当则会造成对生产的影响，也会影响劳动效率和工作速度，甚至会影响设备的运行；一些纺织厂夏季不能满足车间的供冷量，不但影响了工人的身体健康，而且也影响了生产的正常运行；因此，有必要针对空调制冷予以改善，以便更加节能和使用，提高工作效率。
发明内容
本发明的目的在于提供一种纺织厂空调节能方法，以便更好地针对纺织厂进行节能。
为了实现上述目的，本发明的技术方案如下： 
一种纺织厂空调节能方法，包括以下步骤：
（1）改造喷淋泵：结合室外和车间空气参数、采用变频自动调节喷水量的方法，既保证了车间的温湿度恒定，又可使空调系统始终在高效节能的状况下运行；该项目根据回风温湿度信号计算当前的露点温度，并与设定的温湿度计算露点温度比较，通过PID调节器计算，调节新风、回风、排风比例和冷冻水量；通过PID计算，调节二次回风阀开度与喷淋泵频率；
（2）调整空调送回风参数：调整送回风风扇的位置、调整送回风电机大小、调整送回风风扇叶片的重量和角度；调整送回风风扇的位置，目的是为了加大送风量和回风量,减少其损失，将送回风风扇的底座位置分别向送回口位置前移，减少送回口的直径大小，减少送风室的面积，改变送风室的送风位置，减少送风量；这样可使送风增加10%~20%，回风增加15%~30%，调整送回风电机大小；调整送回风风扇叶片的重量和角度，使送回风量增加，风扇叶片变轻巧，也为降低送回风电机功率做好了准备工作，送回风风扇叶片位置的变换和叶片材质的变换，可以使纺织厂空调能耗约降低5%~10%；
（3）采用离心式冷水机组：针对夏季细纱车间断头吸棉排风高温干燥的特点，棉纺织企业完全可以采用间接蒸发冷却技术对断头吸棉排风进行预冷，降低其焓值后再进入喷水室，从而减小喷水室机械制冷负荷。
该发明的有益效果在于：该发明技术有效地针对空调节能，有利于环保，也有利于生产，且能降低成本。
具体实施方式
下面结合实施例对本发明的具体实施方式进行描述，以便更好的理解本发明。
