本发明涉及空调器技术领域，尤其涉及一种空调器的控制方法、控制器、空调器及存储介质。
空调系统为了提高整个系统的工作寿命，通常在空调系统的整个逻辑控制过程中，都需要基于空调系统的室外环境温度，无论室外环境温度是高温还是低温，都需要先检测其室外环境温度，才能进行下一步逻辑判断。目前，用于检测室外环境温度的传感器绝大部分都是设置在翅片或旁边的钣金上，以便在风机循环过程能准确检测当前环境温度。但是如此放置传感器容易受安装环境和太阳、冷凝器表面辐射影响，导致该传感器的检测结果与实际室外环境温度存在差异，更甚的是当该传感器受到太阳辐射影响时，检测的室外环境温度值可能比实际室外环境温度偏高10℃以上，使得空调系统直接判断室外温度超出正常运行范围，从而导致空调系统无法运行。

在相关技术中，空调系统为了提高整个系统的工作寿命，通常在空调系统的整个逻辑控制过程中，都需要基于空调系统的室外环境温度，无论室外环境温度是高温还是低温，都需要先检测其室外环境温度，才能进行下一步逻辑判断。目前，用于检测室外环境温度的传感器绝大部分都是设置在翅片或旁边的钣金上，以便在风机循环过程能准确检测当前环境温度。但是如此放置传感器容易受安装环境和太阳、冷凝器表面辐射影响，导致该传感器的检测结果与实际室外环境温度存在差异，更甚的是当该传感器受到太阳辐射影响时，检测的室外环境温度值可能比实际室外环境温度偏高10℃以上，使得空调系统直接判断室外温度超出正常运行范围，从而导致空调系统无法运行。
基于上述情况，本发明实施例提供了一种空调器的控制方法、控制器、空调器和计算机可读存储介质，该空调器的控制方法包括但不限于如下步骤：

下面结合附图，对本发明实施例作进一步阐述。
如图1所示，图1是本发明一个实施例提供的用于执行空调器的控制方法的系统架构平台的示意图。
本发明实施例的系统架构平台1000包括一个或多个处理器1001和存储器1002，图1中以一个处理器1001及一个存储器1002为例。
处理器1001和存储器1002可以通过总线或者其他方式连接，图1中以通过总线连接为例。
存储器1002作为一种非暂态计算机可读存储介质，可用于存储非暂态软件程序以及非暂态性计算机可执行程序。此外，存储器1002可以包括高速随机存取存储器，还可以包括非暂态存储器，例如至少一个磁盘存储器件、闪存器件、或其他非暂态固态存储器件。在一些实施方式中，存储器1002可选包括相对于处理器1001远程设置的存储器1002，这些远程存储器可以通过网络连接至该系统架构平台1000。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
本领域技术人员可以理解，图1中示出的装置结构并不构成对系统架构平台1000的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
在图1所示的系统架构平台1000中，处理器1001可以用于调用存储器1002中储存的空调器外机除霜控制程序，从而实现空调器的控制方法。
基于上述系统架构平台1000的硬件结构，提出本发明的空调器的控制方法的各个实施例。
如图2所示，图2是本发明一个实施例提供的空调器的控制方法的流程图。本发明实施例的空调器的控制方法，包括但不限于有步骤S100、步骤S200、步骤S300、步骤S400和步骤S500。
步骤S100，获取室外环境温度的第一室外温度值。
具体地，空调器的室内机接收到要求启动空调器的开机指令或者运行过程中，为了提高整个系统的工作寿命，通常在空调系统的整个逻辑控制过程中，都需要基于空调系统的室外环境温度，无论室外环境温度是高温还是低温，都需要先检测其室外环境温度，即此时，空调器会根据该开机指令通过设置在室外机上用于监测室外环境温度的温度传感器获取室外环境温度的第一室外温度值。
步骤S200，在第一室外温度值大于预设室外温度值的情况下，启动空调器的室外风机。
具体地，如果接收到开机指令之后的检测的第一个室外环境温度值(第一室外温度值)大于预设室外温度值的情况下，证明现在的室外环境温度不符合空调器启动运作的条件，又或者是室外温度传感器接收到的温度存在偏高问题，例如，用于检测室外环境温度的温度传感器设置在室外机的翅片或旁边的钣金上，当该传感器受到太阳辐射影响时，检测的室外环境温度值可能比实际室外环境温度偏高10℃以上，导致会出现第一室外温度值大于预设室外温度值的情况；但是由于只检测了一个室外环境温度值，空调器无法判定出现的上述情况的具体原因，为了保护空调器，此时不能开启空调器，启动空调器的室外风机，对室外温度传感器附近的温度进行降温。
需要说明的是，预设室外温度值为空调器允许工作的最大环境温度值，该预设室外温度值根据不同的空调器是不同的，本实施例对其不作具体限定。
需要说明的是，对于室外风机的运行风速不做具体限定，可以根据第一室外温度值与预设室外温度值的差值确定，也可以是预设的默认值，本实施例对其不作具体限定。
需要说明的是，在第一室外温度值小于或者等于预设室外温度值的情况下，证明目前的室外环境温度符合启动空调器的要求，可以直接将用于控制空调器启动的室外环境温度 确定为第一室外温度值，然后根据第一室外温度值确定空调器启动的参数并控制空调器启动。
步骤S300，经过第一时间之后，获取室外环境温度的第二室外温度值。
具体地，在室外风机工作第一时间之后，如果是室外环境温度太高还是存在室外温度传感器接收到的温度存在偏高问题，那么此时用于检测室外环境温度的温度传感器周围受到太阳辐射影响的室外机的翅片或旁边的钣金的温度会有下降，那么此时可以再次检测空调器的室外环境温度的第二室外温度值。
需要说明的是，第一时间可以是根据室外风机的运行风速所确定，也可以是预设的默认值，例如：可以是5分钟，或者可以是6分钟，本实施例对其不作具体限定。
步骤S400，将第二室外温度值与预设室外温度值进行比较，得到第一比较结果。
具体地，将室外环境温度的温度传感器检测到的第二室外温度值和预设室外温度值进行比较，能够得到第一比较结果，第一比较结果可以是第二室外温度值大于预设室外温度值，第一比较结果还可以是第二室外温度值小于或者等于预设室外温度值，还可以是第二室外温度值与预设室外温度值的差值，本实施例对其不作具体限定。
步骤S500，根据第一比较结果确定用于控制空调器启动的室外环境温度。
具体地，当第一比较结果为第二室外温度值小于或者等于预设室外温度值，即通过室外风机对温度传感器周围进行降温后，所检测到的室外环境温度符合空调器的启动条件，那么此时可以将用于控制空调器启动的室外环境温度确定为第二室外温度值，然后根据第二室外温度值确定空调器启动的参数并控制空调器启动。当第一比较结果为第二室外温度值大于预设室外温度值，则可以认为通过室外风机对温度传感器周围进行降温后，温度传感器检测到的第二室外温度值仍未符合空调器的启动要求，但是为了用户使用要求，可以将用于控制空调器启动的室外环境温度确定为预设的第一默认室外温度，该预设的第一默认室外温度小于第一室外温度阈值，第一室外温度阈值小于预设室外温度值。例如：第一室外温度阈值可以设定为低于预设室外温度值2摄氏度的温度值，然后预设的第一默认室外温度可以设置为比较接近但小于第一室外温度阈值的温度值，那么根据预设的第一默认室外温度确定空调器的启动的参数并控制空调器启动，可以使得空调器运作在比较低功率的状态下，尽量降低室外温度值对空调器的运作的影响。
需要说明的是，根据根据不同的用于控制空调器启动的室外环境温度所确定空调器启动的参数，可能是相同的，也可能是不相同的，例如，某一空调器设置的是根据室外温度值确定室外温度范围，然后再根据室外温度范围确定空调器启动的参数，那么此时虽然多 个用于控制空调器启动的室外环境温度值可能不同，但是如果多个用于控制空调器启动的室外环境温度值刚好属于在同一个室外温度范围，那么所确定空调器启动的参数可能是相同的；又例如，某一空调器设置的是根据用于控制空调器启动的室外环境温度值直接确定空调器启动的参数，那么此时多个用于控制空调器启动的室外环境温度值不同的情况下所确定空调器启动的参数必然是不相同的。
需要说明的是，空调器的启动的参数可以包括压缩机的频率、室外风机的转速、室内风机的转速、节流装置的开度等，本实施例对其不作具体限定，根据不同的空调器的结构可以设置不同需要调整的参数。
需要说明的是，本实例对于预设的第一默认室外温度和第一室外温度阈值均不作具体限定，根据根据实际情况或者不同的空调器进行设置。
在步骤S100至S500的实施例中，在接收到开机指令时，空调器首先对室外环境温度进行检测，得到第一室外温度值，如果第一室外温度值大于预设室外温度值的情况下，证明现在的室外环境不符合空调器启动运作的条件或者是室外温度传感器接收到的温度存在偏高问题，此时为了保护空调器，不能开启空调器，需要启动空调器的室外风机，对室外温度传感器附近的温度进行降温，室外风机运作第一时间之后，获取室外环境温度的第二室外温度值，然后将第二室外温度值与预设室外温度值进行比较，根据第一比较结果确定用于控制空调器的室外环境温度，可以根据用于控制空调器的室外环境温度控制空调启动，即通过室外风机降温之后，可以根据用于控制空调器启动的室外环境温度确定空调器启动的参数并控制空调器启动，即通过室外风机对温度传感器周围的温度降温，重新根据降温后检测的第二室外温度值的情况确定用于控制所述空调器的室外环境温度，在不需要更改室外环境温度的温度传感器的放置位置，能够有效防止出现因为对室外环境温度误判而无法运行的问题，而且也不会出现在温度补偿的方案中室外环境温度的初始值不准确而导致的温度补偿值也不准确的问题。
参照图3，根据预设的第一默认室外温度确定空调器的启动的参数并控制空调器启动的情况下，在步骤S500之后，该方法包括但不限于以下步骤S310、步骤S320、步骤S330和步骤S340：
步骤S310，经过第二时间之后，获取空调器的系统运行监测数据；
步骤S320，在系统运行监测数据小于或者等于运行数据阈值的情况下，获取蒸发温度；
步骤S330，在蒸发温度大于目标蒸发温度的情况下，提高空调器的压缩机的频率；
步骤S340，在系统运行监测数据大于运行数据阈值的情况下，保持空调器当前的运行 参数。
在一实施例中，根据预设的第一默认室外温度确定空调器的启动的参数并控制空调器启动的情况下，空调器运行第二时间之后，可以对系统运行监测数据进行检测，系统运行监测数据至少包括室外换热器的温度、空调器的排气压力、空调器的排气温度和模块散热片的温度等，如果检测到的系统运行监测数据中有其中一个或者多个大于运行数据阈值，即表明空调器存在限频问题，那么则保持以第一默认室外温度确定空调器的启动的参数继续运行。如果在系统运行监测数据小于或者等于运行数据阈值的情况下，即表明空调器不存在限频问题，那么此时可以获取空调器当前的回气饱和压力下的蒸发温度，在蒸发温度大于目标蒸发温度的情况下，可以提高空调器的压缩机的频率。提高空调器的压缩机的频率之后，需要继续对系统运行监测数据进行检测，系统运行监测数据大于运行数据阈值，空调器存在限频问题，那么此时则不对空调器进行升频控制，保持空调器当前的空调器的运行参数，如果系统运行监测数据小于或者等于运行数据阈值，空调器不存在限频问题，那么在蒸发温度大于目标蒸发温度的情况下，可以提高空调器的压缩机的频率，此处不在详细赘述。
对于本实施例中的提高空调器的压缩机的频率的步骤，可以是一个逐步调整上升的过程，每次检测到的蒸发温度大于目标蒸发温度，且系统运行监测数据均小于或者等于运行数据阈值的情况下，可以继续提高空调器的压缩机的频率。需要说明的是，每次提高压缩机的频率可以是一个固定的值，例如：压缩机的频率每次都提升2Hz/min或者3Hz/min，也可以是一个变化值，例如：压缩机的频率第一次提升2Hz/min，第二次提升3Hz/min，第三次提升2Hz/min，本实施例对其不作具体限定，可以根据实际情况设置。
需要说明的是，空调器可以通过压力传感器检测到的蒸发压力来计算室内机的饱和蒸发温度，也可以直接将温度传感器检测到的蒸发温度作为室内机的饱和蒸发温度，只要控制器能够获取到室内机的饱和蒸发温度即可，本实施例对其不作具体限定。
需要说明的是，第二时间可以是30分钟，或者可以是25分钟，或者可以是28分钟，本实施例对其不作具体限定，可以根据不同空调器进行不同的设置。
参照图4，在空调器处于制冷模式的情况下，在步骤S500之后，该方法包括但不限于以下步骤S410、步骤S420、步骤S430和步骤440：
步骤S410，获取室外环境温度的第三室外温度值；
步骤S420，在第三温度值低于第二室外温度阈值的情况下，在室外风机每运行预设单位时间后，获取一次室外环境温度的第四室外温度值；
步骤S430，在预设的N个周期后，得到N个第四室外温度值，N为大于等于2的正整数；
步骤S440，根据N个第四室外温度值中的最大值和最小值，确定用于控制空调器的室外环境温度。
具体地，空调器在制冷模式运作的过程中，压缩机的频率、室外风机的转速均处于一个自动化的动态调节的控制模式下，在此模式下，空调器会多个不同的情况对室外风机进行启停控制，在室外风机停止的情况下，用于测量室外温度的温度传感器检测到的室外环境温度值会升高，在室外风机启动的情况下，用于测量室外温度的温度传感器检测到的室外环境温度值会降低。那么在室外温度的温度传感器间断性地检测到室外环境温度值大于第二室外温度阈值，和室外环境温度值小于第四室外温度阈值的情况下，获取室外环境温度的第三室外温度值，在第三温度值低于第二室外温度阈值的情况下，在室外风机每运行预设单位时间后，获取一次室外环境温度的第四室外温度值，并对该周期的第四室外温度值进行记录，那么在经过预设的N个周期后，可以得到N个第四室外温度值，N为大于等于2的正整数，从N个第四室外温度值确定得到N个第四室外温度值中的最大值和最小值，然后根据最大值和最小值的情况，确定用于控制空调器的室外环境温度，并根据用于控制空调器的室外环境温度对空调器的运行参数进行调整，即对室外环境温度的变化程度进行监测，根据室外环境温度变化程度所确定用于控制空调器的室外环境温度的准确度更高，能够更加贴近空调器实际的室外环境温度对空调器进行调整控制。
在一实施例中，空调器在制冷模式运作的过程中，压缩机的频率、室外风机的转速均处于一个自动化的动态调节的控制模式下，在此模式下，空调器会多个不同的情况对室外风机进行启停控制，在室外风机停止的情况下，用于测量室外温度的温度传感器检测到的室外环境温度值会升高，在室外风机启动的情况下，用于测量室外温度的温度传感器检测到的室外环境温度值会降低。那么在室外温度的温度传感器间断性地检测到室外环境温度值大于5摄氏度，和室外环境温度值小于2摄制度的情况下，进入室外环境温度值小于5摄氏度的控制逻辑，当检测到的第三温度值低于5摄氏度的情况下，在室外风机每运行预设单位时间后，获取一次室外环境温度的第四室外温度值，连续记录5个周期，从记录的5个第四室外温度值中确定最大值和最小值，然后根据最大值和最小值的情况，确定用于控制空调器的室外环境温度，即可以通过最大值和最小值确定室外环境温度的变化程度，根据室外环境温度的变化程度确定用于控制空调器的室外环境温度的准确度更高，能够更加贴近空调器实际的室外环境温度对空调器进行调整控制。
需要说明的是，第二室外温度阈值、第四室外温度阈值、记录周期数量、预设单位时间均可以根据实际情况设置，本实施例对其不作具体限定。
参照图5，步骤440包括但不限于以下步骤S510：
步骤S510，在温度差值小于温度差阈值，且N个第四室外温度值中最小值大于第三室外温度阈值的情况下，将第四室外温度值确定为用于控制空调器的室外环境温度，温度差值为N个第四室外温度值中最大值和最小值的差值。
具体地，在N个第四室外温度值中最大值和最小值的差值小于温度差阈值，且N个第四室外温度值中最小值大于第三室外温度阈值的情况下，证明室外环境温度变化程度比较稳定，那么此时不需要对用于控制空调器的室外环境温度进行干预，可以将记录的N个第四室外温度值中的其中一个第四室外温度值确定为用于控制空调器的室外环境温度，然后再根据第四室外温度值对空调器的运行参数进行调整控制。
在一实施例中，在5个第四室外温度值中最大值和最小值的差值小于3摄氏度，且5个第四室外温度值中最小值大于-7摄氏度的情况下，证明室外环境温度变化程度比较稳定，那么此时不需要对用于控制空调器的室外环境温度进行干预，可以将记录的5个第四室外温度值中的一个非最大值或者非最小值的第四室外温度值确定为用于控制空调器的室外环境温度，然后再根据该第四室外温度值对空调器的运行参数进行调整控制。
参照图6，步骤440包括但不限于以下步骤S610和步骤S620：
步骤S610，在温度差值小于温度差阈值，且N个第四室外温度值中最小值大于第三室外温度阈值的情况下，获取空调器的室外换热器的室外换热器温度值；
步骤S620，根据室外换热器温度值确定用于控制空调器的室外环境温度的温度值。
具体地，在N个第四室外温度值中最大值和最小值的差值大于温度差阈值，且N个第四室外温度值中最小值大于第三室外温度阈值的情况下，证明室外环境温度变化程度比较大，那么此时需要对用于检测室外环境温度的温度传感器所检测到的第四室外温度值进行干预，不能直接使用检测到的第四室外温度值对空调器的运行参数进行调整控制，获取空调器的室外换热器的室外换热器温度值，然后根据室外换热器温度值确定用于控制空调器的室外环境温度的温度值，即使第四室外温度值在低温制冷停风机时受到换热器辐射影响，第四室外温度值偏差较大的情况下，也不会影响节流阀最小开度的控制输出，不会出现过热度长期低于过热度阈值而导致系统回液的问题。
在一实施例中，如果在预设时间内室外换热器温度值均小于换热器温度阈值，或者在预设M个连续周期内检测室外换热器温度值小于换热器温度阈值的次数大于等于S次的情 况下，将用于控制空调器的室外环境温度的温度值，确定为预设的第二默认室外温度值，其中，M为大于等于2的正整数，S为小于M的正整数，第二默认室外温度值小于第二室外温度阈值，通过室外换热器温度值反确定用于控制空调器的室外环境温度的温度值，即使第四室外温度值在低温制冷停风机时受到换热器辐射影响，第四室外温度值偏差较大的情况下，也不会影响节流阀最小开度的控制输出，不会出现过热度长期低于过热度阈值而导致系统回液的问题。
在一实施例中，在持续的5分钟内，室外换热器温度值均小于7摄氏度的情况下，或者在连续5个周期中，记录得到室外换热器温度值小于7摄氏度的次数大于等于3次以上的情况下，为了防止出现室外换热器的过热度长期低于5℃的问题，将用于控制空调器的室外环境温度的温度值确定为-5摄氏度和5摄氏度之间，并根据该区间的室外环境温度的温度值对空调器的运行参数进行调整控制，即使第四室外温度值在低温制冷停风机时受到换热器辐射影响，第四室外温度值偏高10摄氏度以上的情况下，也不会影响节流阀最小开度的控制输出，不会出现过热度长期低于5℃而导致系统回液的问题。
