本申请涉及空调技术领域，尤其涉及一种空调除霜控制方法、控制装置及空调器。
随着社会的快速发展和人们生活水平的不断提高，人们对生活品质质量的要求也越来越高，空调作为重要电器件也逐渐走进千家万户，被大家所使用。通常空调被大家熟知的功能就是制冷制热功能，但在冬季使用空调时，室外机会随着空调制热长时间的运行而结霜且运行时间越长结霜越多，严重影响空调制热效果甚至对空调压缩机造成损坏，降低空调性能。
空调在低温制热时运行一段时间就会结霜严重，此时需要对空调外机进行除霜；现有技术中空调除霜是依靠四通阀切换即将制热模式转制冷模式进行除霜，但是除霜时存在无法向室内送出热量，造成室内环境温度波动，影响用户舒适性的问题。

下面结合图1至图3描述本申请提供的一种空调除霜控制方法、控制装置及空调器。
本实施例提供的一种空调除霜控制方法，包括：步骤100：获取当前第一室外换热器的盘管温度；步骤200：在盘管温度小于设定温度，且盘管温度小于等于霜点温度的情况下，控制空调对第一室外换热器执行除霜操作，控制第二室外换热器启动。
本实施例提供的空调包括室内换热器、第一室外换热器以及第二室外换热器，开启空调，室内换热器与第一室外换热器连接实现对室内环境的制热。
参考图1，本实施例提供的空调除霜控制方法，步骤100，获取当前第一室外换热器的盘管温度；具体的，通过温度监测装置检测当前第一室外换热器的盘管温度，获取当前第一室外换热器的盘管温度。
进一步地，步骤200：在盘管温度小于设定温度，且盘管温度小于等于霜点温度的情况下，控制空调对第一室外换热器执行除霜操作，控制第二室外换热器启动。
具体的，设定温度为0℃，霜点温度为-2℃，当检测当前第一室外换热器的盘管温度大于0℃时，控制空调以初始状态(空调启动时的运行模式)运行；当检测当前第一室外换热器的盘管温度小于0℃的情况下，将当前第一室外换热器的盘管温度与霜点温度进行对比；检测当前第一室外换热器的盘管温度为-3℃，小于霜点温度-2℃的情况下，控制空调对第一室外换热器执行除霜操作，且控制第二室外换热器启动，即室内换热器断开与第一室外换热器的连接，使室内换热器与第二换热器连接，通过第二室外换热器继续为室内环境送热；这种控制方法，在对第一室外换热器进行除霜时，不影响第二室外换热器对室内环境送热，达到进行除霜的室外换热器不制热，制热的换热器不除霜的效果。
本实施例提供的空调除霜控制方法，通过获取当前第一室外换热器的盘管温度，了解当前第一室外换热器的盘管温度；在盘管温度小于设定温度，且盘管温度小于等于霜点温度的情况下，控制空调对第一室外换热器进行除霜，控制第二室外换热器启动，通过第二室外换热器继续为室内环境送热；即通过控制空调断开室内换热器与第一室外换热器之间的连接，将室内换热器与第二室外换热器连接，对第一室外换热器进行除霜，且可继续对室内环境进行制热；这种控制方法简单，在不影响室内环境制热的情况下，对第一室外换热器进行除霜，避免因对第一室外换热器除霜造成室内环境温度波动，影响用户舒适度，进而提高用户的体验。
本实施例中，关于设定温度不做具体限定，可以是0℃，也可以是3℃等，可根据实际情况进行限定。
本实施例中，关于霜点温度不做具体限定，可以是-2℃，也可以是-1℃等，根据用户实际情况进行限定。
在上述实施例的基础上，本实施例提供的空调除霜控制方法还包括：在盘管温度大于霜点温度的情况下，控制空调以初始状态运行。即，在温度监测装置检测到当前第一室外换热器的盘管温度大于霜点温度的情况下，控制空调以初始状态(空调启动时的运行模式)运行。
在一个具体实施例中，盘管温度小于设定温度0℃，温度监测装置检测第一室外换热器的盘管温度为-1℃，此时盘管温度小于设定温度0℃且大于霜点温度-2℃，控制空调以当前的运行模式继续运行。
本实施例在盘管温度小于设定温度，且盘管温度小于等于霜点温度的情况下，控制空调对第一室外换热器执行除霜操作，且控制第二室外换热器启动；在盘管温度大于霜点温度的情况下，控制空调以初始状态运行；这种控制方法简单，可有效控制对第一室外换热器的除霜操作，且满足室内环境的制热需求。
在上述实施例的基础上，进一步地，在盘管温度小于设定温度，且盘管温度小于等于霜点温度的情况下，控制空调对第一室外换热器执行除霜操作，控制第二室外换热器启动进一步包括：获取设定时间段内盘管的温度平均值；确定第一预设时间内温度平均值中的最小值，其中第一预设时间包括多个设定时间段；基于盘管温度与最小值，确定盘管温度与最小值 之间的差值；在盘管温度小于设定温度，盘管温度小于等于霜点温度，且差值大于等于第一预设温度的情况下，控制空调对第一室外换热器执行除霜操作，控制第二室外换热器启动。
在一个具体实施例中，设定时间段为1min，第一预设时间为3min，本实施例提供的温度监测装置，1min可完成若干次的温度检测，获取每分钟内盘管的温度平均值，例如，温度监测装置1min内对盘管进行10次温度检测，计算10温度的平均值，即为当前1min内盘管的温度平均值。以此方法，获取第一预设时间3min内每分钟内盘管的温度平均值；确定3min内3个温度平均值中的最小值。
进一步地，基于盘管温度与最小值，确定盘管温度与最小值之间的差值，将差值与第一预设温度进行对比，根据差值与第一预设温度之间的关系，控制空调对第一室外换热器执行除霜操作，且控制第二室外换热器启动。
具体的，第一预设温度为5℃，当盘管温度与最小值之间的差值大于等于5℃时，控制空调对第一室外换热器执行除霜操作，且控制第二室外换热器启动。
在差值小于第一预设温度的情况下，控制空调以初始状态运行；具体的，在盘管温度与最小值之间的差值小于5℃时，控制空调以初始状态运行。
本实施例中通过获取第一预设时间内盘管的温度平均值中的最小值，确定最小值与当前盘管温度之间的差值，在盘管温度小于设定温度，盘管温度小于等于霜点温度，且差值大于等于第一预设温度的情况下，控制空调对第一室外换热器执行除霜操作，控制第二室外换热器启动；在盘管温度小于设定温度，盘管温度小于等于霜点温度，且差值小于第一预设温度的情况下，控制空调以初始状态运行，这种控制方法可更加精确地控制空调对第一室外换热器进行除霜，避免因第一室外换热器上结霜影响室内环境的制热效果。
本实施例中的设定时间段不仅限于1min，也可以是30s或者10s等，可根据实际情况进行限定。
本实施例中，关于第一预设温度不仅限于5℃，也可以是10℃，可根 据用户的需求进行限定。
本实施例中的第一预设时间不仅限于3min，也可以是5min，10min等。
在上述实施例的基础上，进一步地，本实施例提供的空调除霜方法，还包括：启动空调的制热模式，获取压缩机连续运行时间；在压缩机连续运行时间小于第二预设时间，且盘管温度小于第二预设温度的情况下，控制空调对第一室外换热器执行除霜操作，控制第二室外换热器启动；在压缩机连续运行时间大于等于第二预设时间，小于第三预设时间，且盘管温度小于第三预设温度的情况下，控制空调对第一室外换热器执行除霜操作，控制第二室外换热器启动；其中所述第二预设温度小于第三预设温度。
空调在制热过程中，压缩机长时间运行会造成室外换热器结霜。本实施例在启动空调的制热模式后，监控压缩机的运行时间，即获取空调开启制热模式后，压缩机连续运行的时间，实时掌握压缩机在制热模式下连续运行的时间。
在一个具体实施例中，设定第二预设时间为45min，第二预设温度为-22℃，启动空调的制热模式，压缩机启动制热模式后连续运行时间为40min，此时压缩机的连续运行时间40min小于第二预设时间45min；当前第一室外换热器的盘管温度为-25℃，小于第二预设温度-22℃，此时第一室外换热器上的霜会影响空调的制热效果，需要对第一室外换热器进行除霜，控制空调对第一室外换热器执行除霜操作，同时控制第二室外换热器启动；当检测第一室外换热器的盘管温度为-15℃，当前的盘管温度大于第二预设温度-22℃，此时第一室外换热器上的霜在用户可以接受的范围内或者不影响用户体验，无需进行除霜操作，控制空调以初始状态运行。
进一步地，在压缩机的连续运行时间110min，此时压缩机的连续运行时间大于第二预设时间45min，且小于第三预设时间120min，当前第一室外换热器的盘管温度为-20℃，当前的盘管温度小于第三预设温度-18℃，控制空调对第一室外换热器执行除霜操作，控制第二室外换热器启动，继续为室内换热送热；在检测当前第一室外换热器的盘管温度为-10℃时，当前盘管温度大于第三预设温度-18℃，此时第一室外换热器上的霜对用户的影响较小，满足用户需求，无需对第一室外换热器进行除霜，控制空调以初始状态运行。
在上述实施例的基础上，本实施例提供的空调除霜控制方法，还包括：在压缩机连续运行时间大于第四预设时间的情况下，控制空调对第一室外换热器执行除霜操作，控制第二室外换热器启动；其中第四预设时间大于等于第三预设时间。
空调继续运行，在压缩机的连续运行时间大于第四预设时间480min时，空调制热时间较长，会出现结霜，为避免结霜影响用户体验，需对第一室外换热器进行除霜，控制空调对第一室外换热器执行除霜操作，同时启动第二室外换热器启动，继续为室内环境送热，避免因对第一室外换热器进行除霜，造成室内环境温度的波动，影响用户舒适度。
本实施例根据空调在制热模式下压缩机连续运行的时间，结合当前盘管温度与预设温度之间的关系，可更加精确地控制空调对第一室外换热器执行除霜操作，避免因第一室外换热器结霜影响室内环境的制热效果。
本实施例中，关于第二预设时间、第三预设时间、第四预设时间、第二预设温度、第三预设温度不做具体限定，可根据用户实际情况进行限定，使第二预设时间小于第三预设时间，第三预设时间小于等于第四预设时间，第二预设温度小于第三预设温度即可。
在上述实施例的基础上，控制空调对第一室外换热器执行除霜操作包括：控制加热装置对第一室外换热器进行加热。
具体的，第一室外换热器和第二室外换热器分别与加热装置连接，在第一室外换热器需要除霜时，控制加热装置对第一室外换热器进行加热，第一室外换热器上的霜吸收热量融化；在第二室外换热器需要除霜时，控制加热装置对第二室外换热器进行加热，第二室外换热器上的霜吸收热量融化。
本实施例提供的加热装置不做具体限定，可以是太阳能加热结构，也可以是电加热装置。
进一步地，根据当前第一室外换热器的盘管温度控制加热装置的运行。
具体的，在盘管温度＞-10℃的情况下，控制加热装置的加热功率以1000W运行；在-20℃＜盘管温度≤-10℃的情况下，控制加热装置的加热功率以1500W运行；在盘管温度≤-20℃的情况下，控制加热装置的加热功率以2000W运行。
本实施例中关于盘管温度对应加热装置的加热功率不做具体限定，可以根据实际情况进行限定。
在上述实施例的基础上，本实施例提供的空调除霜控制方法还包括：在除霜时间小于等于第五预设时间，且盘管温度大于第四预设温度的情况下，控制空调除霜操作关闭；或，在除霜时间大于等于第六预设时间的情况下，控制空调的除霜操作关闭，其中所述第六预设时间大于所述第五预设时间。
在一个具体实施例中，控制空调对第一室外换热器执行除霜操作时，在除霜时间小于等于第五预设时间60秒的情况下，获取当前盘管温度，在检测当前盘管温度大于第四预设温度5℃的情况下，控制空调除霜操作关闭。
在另一个实施例中，在除霜时间大于等于第六预设时间10min时，控制空调除霜操作关闭；第六预设时间内可完全将第一室外换热器上的霜清除，这种空调除霜控制方法，可更彻底地去除第一室外换热器上的霜。
本实施例中关于第五预设时间、第四预设温度、第六预设时间不做具体限定，其中第六预设时间大于第五预设时间，可有效去除第一室外换热器上的霜即可。
在上述实施例的基础上，在除霜时间小于等于第五预设时间，盘管温度大于第四预设温度的情况下，控制空调除霜操作关闭进一步包括：在除霜时间小于等于第七预设时间，盘管温度大于第五预设温度的情况下，控制空调除霜操作关闭；其中第七预设时间小于第五预设时间，第四预设温度小于第五预设温度。
在第一室外换热器上的结霜量较大时，除霜时间小于等于第五预设时间，盘管温度大于第四预设温度的情况下，控制空调除霜操作关闭，可能无法彻底将第一室外换热器上的霜清除，有残余，需继续进行除霜操作；具体的，当除霜时间小于等于第七预设时间20秒时，且当前盘管温度大于第五预设温度10℃时，控制空调的除霜操作关闭；这种控制方法可有效控制空调对第一室外换热器上的霜进行清除，避免清除不彻底影响室内环境制热。
本实施例通过在不同的除霜时间内，检测盘管温度与第四预设温度和 第五预设温度之间的关系，控制空调除霜操作关闭，可避免因结霜过厚，除霜不彻底。
本实施例中，关于第五预设温度、第七预设时间不做具体限定，可根据用户需求进行限定，使第七预设时间小于第五预设时间，第四预设温度小于第五预设温度即可。
下面对本申请提供的空调控制装置进行描述，下文描述的空调控制装置与上文描述的空调除霜控制方法可相互对应参照。
