背景技术
空调现如今已经是居家和办公的必用电器，尤其在夏、冬季节，空调更是被长时间地使用。空调夏天可以制冷、冬天可以制热，能够调节室内温度达到冬暖夏凉，为用户提供舒适的环境。
空调在低温环境下制热模式时，由于室外换热器处于低温高湿的环境，因此当空调长时间在低温环境下运行，室外换热器的表面容易结霜，结霜后的室外换热器的换热性能明显下降，会影响空调的运行。现有的空调在进行除霜的过程中，固定的分流状态对于其换热效果具有一定影响，限制了换热器的换热能力，无法使空调达到最佳的除霜效果。

本申请提供一种空调除霜的控制方法，该空调可为挂壁式空调、立柜式空调、窗式空调和吊顶式空调等。
如图1和图2所示，该空调的室内换热器或室外换热器中设有可变分流装置，也可同时在室内换热器和室外换热器中设置可变分流装置，该可变分流装置包括：换向阀3、第一分流管路1、第二分流管路2和至少两个换热管路4。第一分流管路1通过至少两个换热管路4与第二分流管路2连接。第一分流管路1和第二分流管路2中均设有主管道和多个支管道，根据需要可在其中部分支管道中设置单向阀10。
换向阀3为二位四通换向阀，设有第一连通口31、第二连通口32、第三连通口33和第四连通口34，换向阀3具有第一工位和第二工位。第一连通口31与冷媒入口连接，第三连通口33与冷媒出口连接。
该空调具有可变分流状态和固定分流状态。在可变分流状态的情形下，空调的换热器中冷媒实时调整分流状态。在固定分流状态的情形下，空调的室外换热器中冷媒的分流状态固定。
分流状态分为单路分流和多路分流，在多路分流的情形下，空调的室外换热器中冷媒多路分流进行工作。在单路分流的情形下，空调的室外换热器中冷媒单路进行工作。也就是说，在可变分流状态的时候，空调在单路分流和多路分流之间切换，而在固定分流状态的时候，空调固定位单路分流或多路分流进行工作。
多路分流时，换向阀3处于第一工位，第一连通口31与第二连通口32连通，第三连通口33和第四连通口34连通。此时，第二连通口32与第一分流管路1连通，第四连通口34与第二分流管路2连通。冷媒入口的冷媒由第一分流管路1进入，在第一分流管路1的支管道分流，分别进入各个换热管路4与室内空气进行换热，再由第二分流管路2的支管道进入到其主管道，最后经过第四连通口34和第三连通口33，由冷媒出口排出，实现由多条管路的换热。
单路分流时，换向阀3处于第二工位，第一连通口31与第四连通口34连通，第三连通口33与第二连通口32连通。此时，第二连通口32与第二分流管路2连通，第四连通口34与第一分流管路1连通。冷媒入口的冷媒由第二分流管路2进入，由于第一分流管路1中的部分管道中设置单向阀10，再其限制下，冷媒仅能够在部分换热管路4中换热排出，此时可减少换热管路。
本实施例中，以两个换热管路4为例，分别为第一换热管路和第二换热 管路。第一分流管路1和第二分流管路2均设有一个主管道和两个支管道。第一分流管路1中的一个支管道中设有单向阀10。假设仅在第一分流管路1的其中一支管道中设置单向阀10
多路分流时，换向阀3处于第一工位，第一连通口31与第二连通口32连通，第三连通口33和第四连通口34连通。此时，第二连通口32与第一分流管路1连通，第四连通口34与第二分流管路2连通。冷媒入口的冷媒由第一分流管路1进入，在第一分流管路1的支管道分流，分别进入第一换热管路和第二换热管路与室内空气进行换热，再由第二分流管路2的支管道进入到其主管道，最后经过第四连通口34和第三连通口33，由冷媒出口排出，实现两条管路的同时换热。
单路分流时，换向阀3处于第二工位，第一连通口31与第四连通口34连通，第三连通口33与第二连通口32连通。此时，第二连通口32与第二分流管路2连通，第四连通口34与第一分流管路1连通。冷媒入口的冷媒由第二分流管路2进入，由于第一分流管路1中的支管道中设置单向阀10，再其限制下，冷媒仅能够在第一换热管路4中换热排出，此时仅通过一个换热管路4进行换热。
如图3所示，空调除霜的控制方法包括如下步骤：
步骤S110：在满足除霜条件的情形下，控制空调进入除霜模式。
空调开启后，空调可自动判断其是否满足除霜的条件。例如，当室外环境温度小于5℃时，如果空调工作在制热模式，开始判断空调的运行时间是否大于设定累计运行阈值，若运行时间大于设定累计运行阈值，则说明空调满足除霜条件，控制空调进入除霜模式。
步骤S120：基于空调的结霜情况，控制调整压缩机的运行频率和空调的运行状态。
在空调进入除霜模式之后，基于空调的结霜情况，判断并控制调整压缩机的运行频率和空调的运行状态。运行状态包括：可变分流状态和固定分流状态。空调在可变分流状态的情形下，空调的换热器中冷媒实时调整分流状态，换热器可为室内换热器或室外换热器。在固定分流状态的情形下，换热器中冷媒的分流状态固定。
具体地，基于空调的结霜情况，例如根据空调的运行情况、室外温度、室 外换热器的结霜的厚度或结霜的时间，判断空调以目前状态进行除霜是否满足除霜需求。
若空调以目前状态进行除霜能够满足除霜需求，空调以目前的分流状态能够正常工作，单路分流或多路分流均可满足要求，则控制压缩机以固定频率运行，并控制空调处于固定分流状态。
若空调以目前状态进行除霜不满足除霜需求，说明空调以目前的分流状态无法正常工作，则控制调整压缩机的运行频率，并控制空调处于可变分流状态，空调的室内换热器或室外换热器中冷媒实时通过换向阀调整分流状态。
本申请提供的空调除霜的控制方法，在满足除霜条件的情形下，先控制空调进入除霜模式，在空调进行除霜的过程中，基于空调的结霜情况，控制调整压缩机的运行频率和空调的运行状态，使空调在可变分流状态和固定分流状态之间切换，改变换热器的分流状态，使空调达到最佳的除霜效果。
如图4所示，若空调不满足除霜需求，控制调整压缩机的运行频率，并控制空调处于可变分流状态的步骤包括：
步骤S410：控制空调以单路分流进行工作，并控制压缩机以第一工作频率运行。
为防止空调突然在制热模式转变为除霜模式的过程中，管内压力过大防止冲击用于冷媒转向的四通阀，进入除霜模式的过程中，先控制压缩机关闭，获取压缩机关闭的时间，在确定压缩机关闭的时间达到第一预设时间后，例如在压缩机关闭1分钟之后，再控制空调调整冷媒方向以制冷模式运行。
由于空调以目前状态进行除霜不满足除霜需求，在压缩机开启前，先控制空调以单路分流进行工作，再控制压缩机以第一工作频率运行。此时压缩机会以低频模式运行，并以单路分流进行化霜，以便于热量的挥发。
步骤S420：控制空调以多路分流进行工作，并控制压缩机以第二工作频率运行。
空调以单路分流运行一段时间后，室外换热器中冷媒的温度逐渐上升，当冷媒的温度达到一定温度或温度逐渐稳定后，控制空调以多路分流的状态进行工作，并控制压缩机以第二工作频率运行。其中，第二工作频率大于第一工作频率。此时压缩机会以高频模式运行，并以多路分流进行化霜，以增加换热量。最后在除霜完成后，空调退出除霜模式，重新进入制热模式。
此外，根据需要还可设置三路或者四路换热管路，从而分流状态还可设置部分分流的中间状态，在部分分流的状态，可利用部分换热管路进行换热，以保证运行过程中根据需要进行选择。
若空调还设有部分分流的中间装置，则在可变分流的过程中，还可先以单路分流的状态进行工作，再以部分分流的状态进行工作，或者先以部分分流的状态进行工作，再以多路分流的状态进行工作。
为保证在单路分流向多路分流切换过程中，压缩机能够正常工作，在步骤S410和步骤S420之间还包括：
在空调以单路分流进行工作，且压缩机以第一工作频率运行后，先获取压缩机的回油状态。再根据压缩机的回油状态，确定压缩机在第一工作频率和单路分流情形下，确定回油的时间。
确定回油的时间后，在压缩机完成回油前的第二预设时间内，控制空调以多路分流进行工作。例如，在压缩机完成回油前的5秒内，利用换向阀调整分流状态，控制空调以多路分流进行工作。
若能够满足除霜需求，控制压缩机以固定频率运行，并控制空调处于固定分流状态的步骤包括：控制空调以当前分流状态进行工作，并控制压缩机以固定频率运行。
具体地，在进入除霜模式的过程中，先控制压缩机关闭，获取压缩机关闭的时间，在确定压缩机关闭的时间达到第一预设时间后，例如在压缩机关闭1分钟之后，再控制空调调整冷媒方向以制冷模式运行。
由于空调以目前状态进行除霜能够满足除霜需求，在压缩机开启前，控制空调以当前分流状态进行工作，若此时空调处于单路分流，则以单路分流进行工作，若此时空调处于多路分流，则以多路分流进行工作，由于分流状态未发生改变，则此时压缩机以固定频率运行。
