The invention relates to a control method and device for air conditioner defrosting, and an air conditioner. The control method comprises the steps: when the air conditioner operates in a heating mode, the temperature of an outdoor coil pipe of the air conditioner after a compressor operates for the set duration is obtained; and when the temperature of the outdoor coil pipe and a fluctuation boundary value of the temperature of the outdoor coil pipe meet preset conditions, the air conditioner is controlled to enter into a defrosting mode, wherein the fluctuation boundary value of the temperature of the outdoor coil pipe comprises the minimum value or the maximum value of the temperature, obtained after the compressor is started to operate for the preset duration within the set duration, ofthe outdoor coil pipe. According to the method for defrosting judgment control based on the change of the temperature state of the outdoor coil pipe in the operation process of the air conditioner, the air conditioner can be more accurately controlled to trigger and execute a defrosting process, and the problems of false triggering, frequent triggering and the like of the defrosting process in related technologies are reduced.
Description
technical field [0001] 本申请涉及空调除霜技术领域,例如涉及一种用于空调除霜的控制方法、控制装置及空调。 Background technique [0002] 随着人们生活水平的提高,空调设备也已经走进了千家万户,家用空调、中央空调的使用越来越普遍,用户对于空调舒适度的要求也越来越高,空调使用过程中所存在的问题也逐渐暴漏出来,其中一个就是空调在严寒气候下运行时的室外机结霜冻结的问题。在空调在低温地区或者风雪较大的地区运行时,室外机的冷凝器外表面所凝结水流会滴落到底盘上,空调器长时间运行情况下,会导致空调器的冷凝器和底盘均出现结冰问题,室外机上凝结的冰层会阻碍内部的冷媒与室外环境的热量交换,使得空调的制冷效率下降,为了保证空调的制热效果,空调不得不提高功率运行,这也导致了电能的额外消耗和用户使用成本的提高。 [0003] 因此,针对空调的室外机结霜结冰的问题,现有的部分空调配置有除霜功能,例如,利用设置于室外机的加热装置对室外机进行加热,或者,利用压缩机排出的高温冷媒对室外换热器进行化霜融冰。这里,在空调启用除霜功能之前,空调一般是利用室外传感器检测到的外盘管温度与霜点温度结合进行判断是否已经达到了容易凝结冰霜的温度状况,进而判断是否启用除霜功能。 [0004] 在实现本公开实施例的过程中,发现相关技术中至少存在如下问题:空调一般是以外环温相较于霜点温度的大小作为空调是否需要除霜的判断条件;由于影响空调室外机结霜程度的因素不仅包括外界环境因素,还包括空调自身状态的影响因素;因而在空调除霜前后外环温等参数的变化量较小等部分情况下,由于空调每次除霜完成之后自身各部件的工作状态也会发生变化,如果仍以该种方式判断并控制空调是否需要除霜,则实际上会与空调实际的结霜状态存在较大的误差,容易导致除霜功能误触发、频发触发等问题,因此不能够满足空调精准控制触发除霜功能的需要。 Contents of the invention [0005] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is presented below. The summary is n...
