摘要
空调变频技术的发展使得通过控制算法实现空调节能成为可能。本文首先介绍了变频空调的节能原理和相关的基本控制算法,主要包括分段定点控制、PID控制与以模糊逻辑控制为代表的智能控制方法。这些控制方法的节能原理主要依赖于变频空调相对定频空调避免了频繁启停带来的能量损失,使空调能在较高的效率下运行。但变频空调的节能潜力不止于此,本文结合中央空调节能控制算法,对基于空调模型和基于舒适度的两类进一步发挥变频空调节能潜力的控制算法进行阐述。最后本文介绍了基于人体真实体感数据而不仅仅是回风数据的家用空调控制算法。
The development of air-conditioner converter technology makes it possible to use advanced control methods to save energy.In this paper,the energy-saving principle of variable-frequency operated air-conditioners and related control methods including segmentation fixed point control,PID control,and intelligent control methods represented by fuzzy logic control,are presented.The reason why these methods were energy-saving was that variable-frequency operated air-conditioners avoided the energy loss caused by the frequent on-off versus fixed frequency air-conditioners.However,the energy-saving potential of variable-frequency air-conditioners was far beyond this.With reference to those of central air conditioning systems,the control methods based on air-conditioner models and human comfort which could fulfill the energy-saving potential of variablefrequency air-conditioners were introduced.Finally the control methods based on data reflecting human thermal feeling instead of merely return temperature were described.
