摘要
针对原有中央空调系统运行高耗能和空调效果不均衡等问题,提出一种切实可行的改造方案,该方案运用PID控制、模糊控制、反馈控制和变频控制技术,对冷冻水泵和空调系统末端设备进行节能控制和联动运行。夏天,空调机组暴晒于屋面,能效较低,针对这一问题,提出对空调机组进行喷雾降温和简单遮阳以提升能效。实际运行结果表明,该方案可靠、高效,节能效果显著。
Aimingat the issues of high energy consumption and unbalanced air conditioning effect of the original central air-conditioning system,this paper proposes a feasible reconstruction scheme what applicate PID control,fuzzy-logic control,feedback control and variable-frequency regulation technology to make chilled water pump and terminal devices for energy-saving and linkage operation. In summer,the air-conditioner sets are exposed to the roof and low energy efficiency. Aiming at the problem,this paper proposes to spray cooling and simple shading to improve energy efficiency. The practical results indicate that the scheme is reliable,efficient,and energy-saving effect is outstanding.
