结合图1所示，本公开实施例提供一种用于空调器的控制方法，包括：
S101，在空调器的压缩机持续运行第一预设时长的情况下，检测元件检测空调器的温度参数和空调器室外机的总电流；其中，温度参数包括一个或多个。
本公开实施例中，在空调器的压缩机持续运行第一预设时长后，开始检测相关参数。这里，第一预设时长的最小取值为3分钟。因压缩机启动初期，系统运行不稳定，相关参数波动较大。所以待压缩机运行一段时间后，再进行参数的检测。空调器的温度参数通过设置在空调器上的温度传感器进行检测，室外机总电流通过电流检测装置如电流检测传感器等进行检测。其中，空调器的温度参数包括室内机盘管温度、室外机盘管温度、压缩机排气温度等参数中的一种或多种。室外机的总电流包括室外机的压缩机、电机、控制板及阀等部件的总电流。
S102，处理器根据空调器的运行模式，确定温度参数对应的预设条件。
本公开实施例中，空调器处于不同的运行模式下，判定截止阀开启与否的预设条件不同。这里，运行模式主要指制热模式或制冷模式。以检测温度包括室内盘管温度为例进行说明。在制冷模式下，室内盘管温度对应的预设条件是室内盘管温度与室内环境温度的差值大于第一阈值。在制热模式下，室内盘管温度对应的预设条件是室内盘管温度与室内环境温度的差值大于第二阈值。其中，第二阈值大于第一阈值，第一阈值的取值范围为负值，第二阈值的取值为正值。空调器制冷时，室内盘管温度小于室内环境温度。而空调器制热时，室内盘管温度大于室内环境温度。因此，在不同运行模式下，检测的温度参数对应的预设条件不同。这样，有助于结合运行模式，精确地设置预设条件，从而提高判断的精准 度。
S103，处理器在任一温度参数满足对应的预设条件，且总电流大于电流阈值的情况下，控制压缩机停机。
这里，电流阈值与压缩机的运行频率及空调器的制冷能力具有对应关系，通过获取压缩机的运行频率及空调器的制冷能力，即可确定电流阈值。其中，压缩机的运行频率是指压缩机启动一段时长后的运行频率。进一步地，电流阈值也可以针对空调器运行不同模式设定不同的电流阈值。在冷媒的截止阀未打开时，因冷媒得不到有效的流通，室内温度无法达到目标温度。空调器会提高压缩机的功率，因此，室外机的总电流在增大。在室外机的总电流大于电流阈值，且任一检测的温度参数满足对应的预设条件的情况下，确定截止阀未开启，则控制压缩机停机。从而避免压缩机长时间运转损坏或爆炸的风险问题。
采用本公开实施例提供的用于空调器的控制方法，在空调器的压缩机持续运行一段时长后，检测空调器的温度参数和室外机的总电流。并根据空调器的运行模式，确定判断压缩机停机保护的预设条件。在任一检测温度参数满足对应的预设条件，且总电流大于电流阈值的情况下，控制压缩机停机。这样，针对空调器不同的运行模式，设置不同的预设条件。有助于提高判断预设条件的准确性和可靠性。
可选地，步骤S101，检测元件检测空调器的温度参数，包括：检测室内机盘管的温度，和/或，压缩机的吸气温度，和/或，室外机盘管的温度和室外换热器出液端的温度。
本公开实施例中，检测空调器的温度参数包括室内机盘管的温度、压缩机的吸气温度，及室外机盘管的温度和室外换热器出液端温度的一种或多种。其中，室内机盘管温度、室外机盘管温度及压缩机吸气温度均与冷媒流量有关。因此，检测空调器的温度参数主要是指与冷媒流量有关的部件或位置的温度。此外，可以理解地是，在检测温度参数仅包括一种时，则在该检测温度参数满足预设条件，且总电流大于电流阈值时，控制压缩机停机。在检测温度参数包括多种时，可以是同时判定多个温度参数是否满足其对应的预设条件，在任意一个温度参数满足对应的预设条件时，且总电流满足条件，则控制压缩机停机。或者，可以是将多个温度参数按照一定的嵌套逻辑判断。
作为一种示例，检测温度参数包括室内机盘管的温度，压缩机的吸气温度。则嵌套逻辑为在总电流满足条件下，判断吸气温度是否满足预设条件，若满足则控制压缩机停机。若吸气温度不满足对应的预设条件，则进一步判断室内机盘管的温度，在室内机盘管温度满足对应的预设条件的情况下，控制压缩机停机。若室内机盘管温度不满足对应的预设条件，则重新判断。这里，嵌套控制逻辑中，设定检测参数的判定顺序从高到低依次是总电流判定、吸气温度判定、室内机盘管温度和室外机盘管温度。其中，室内机盘管温度和室 外机盘管温度不分先后顺序。这样，可以通过检测多个参数和设定多个判定条件来判断截止阀的开关状态，从而避免单一传感器故障或检测不准确而导致误判的情况。相比单一传感器，有助于提高判断的安全可靠性。
可选地，步骤S102，处理器根据空调器的运行模式，确定温度参数对应的预设条件，包括：
处理器在空调器运行制冷模式的情况下，确定对应的预设条件包括：室内机盘管的温度T m与当前室内环境温度T ai的差值大于或等于第一温度阈值T 1；和/或，压缩机的吸气温度T s大于第二温度阈值T 2；和/或，室外机盘管温度T cm和室外换热器出液端温度T e的最大值小于或等于当前室外环境温度T ao。
本公开实施例中，在制冷模式下，对每个检测的温度参数均设有对应的预设条件。这里，第一温度阈值T 1取值为负值，例如-2℃。空调器正常运行时，室内机盘管的温度远远低于当前室内环境温度。因此在室内机盘管温度与当前室内环境温度相差不大的情况下，可判定截止阀未开启。第二温度阈值取值范围为20-30℃，可取值30℃。其中，空调器正常运行制冷模式时，吸气温度取决于室外环境温度和排气温度。在截止阀未开启时，因压缩机功率的提高，导致压缩机的排气温度升高，从而使得吸气温度不断升高。因此，第二温度阈值的取值范围高于正常运行时压缩机的吸气温度。此外，取室外机盘管温度和室外换热器出液端温度的最大值，即max(T cm，T e)，将二者的最大值与当前室外环境温度比较。其中，室外换热器出液端温度是指室外换热器出液管路中某一支路表面温度。在空调器正常运行状态下，室外机盘管温度高于室外换热器出液端温度。但在本实施例中，若二者中的最大值仍小于或等于当前室外环境温度，则表明管路中冷媒的流通不足，可判定截止阀未开启。
可选地，步骤S102，处理器根据空调器的运行模式，确定温度参数对应的预设条件，包括：
处理器在空调器运行制热模式的情况下，确定对应的预设条件包括：室内机盘管的温度T m与当前室内环境温度T ai的差值大于或等于第三温度阈值T 3；和/或，压缩机的吸气温度T s大于第四温度阈值T 4；和/或，室外机盘管温度T cm和室外换热器出液端温度T e的最大值与当前室外环境温度T ao的差值绝对值大于或等于预设阈值。
本公开实施例中，第三温度阈值取值为正值，例如3℃。其中，第三温度阈值的绝对值可等于第一温度阈值的绝对值。第四温度阈值可以等于或小于第二温度阈值，因制热模式下的吸气温度高于制冷模式，这里，第四温度阈值取值范围为28-35℃。此外，预设阈值取值范围0-3℃。在max(T cm，T e)与当前室外换进温度的差值较小时，表明管路中冷媒 流通不足，可判定截止阀未开启。
可选地，温度参数包括室内机盘管的温度，和/或，室外机盘管的温度和室外换热器出液端的温度；步骤S103，处理器通过以下方式确定任一温度参数满足对应的预设条件包括：
处理器在多个检测周期内或第二预设时长内，室内机盘管的温度，或，室外机盘管的温度和室外换热器出液端的温度满足对应的预设条件，确定温度参数满足对应的预设条件。
本公开实施例中，针对温度参数包括室内机盘管温度、或室外机盘管温度和室外换热器出液端的温度、或二者均包含的情况下，确定温度参数满足预设条件的方法。因空调器温度参数会受各种因素影响例如空调器的反复启停发生变化，尤其是盘管温度。为了保证室内外盘管温度检测的稳定性，设定了多个检测周期或第二预设时长。作为一种示例，第二预设时长取值1分钟，以室内机盘管温度为例。当室内机盘管的温度在1分钟内持续满足，T m-T ai≥T 1，或T m-T ai≥T 3时，该室内机盘管的温度满足对应的预设条件。作为另一种示例，多个检测周期包括3个检测周期。这三个检测周期可以是连续的检测周期，也可以是不连续的检测周期。在为不连续的检测周期时，间隔时间不宜过长；可将三个检测周期限定在1小时以内的三个检测周期。仍以室内机盘管温度为例，如果在限定的时长内，检测到3次T m-T ai≥T 1，或T m-T ai≥T 3，则室内机盘管的温度满足对应的预设条件。如此，可有效降低扰动或其他因素导致的误判，提高了判断的可靠性和准确性。
此外，因压缩机排气温度过高的因素较为明确，主要包括压缩机堵转、反转、冷媒有效流通性不足等。这里，不对压缩机排气温度是否满足对应的预设条件的判断设置过多的限制；为了更好地保护压缩机，在压缩机排气温度过高时，即确定满足预设条件，控制压缩机停机。
结合图2所示，本公开实施例提供另一种用于空调器的控制方法，包括：
S201，检测元件在空调器首次上电，且压缩机运行时间大于第一预设时长，且小于时间阈值的情况下，检测空调器的温度参数；其中，温度参数包括室内机盘管的温度，和/或，室外机盘管的温度和室外换热器出液端的温度；并在压缩机运行时长大于第一预设时长的情况下，检测室外机的总电流。
S202，处理器根据空调器的运行模式，确定温度参数对应的预设条件；
S203，处理器在任一温度参数满足对应的预设条件，且总电流大于电流阈值的情况下，控制压缩机停机。
本公开实施例中，在检测的温度参数包括室内机盘管温度、和/或室外机盘管温度的情况下，限定了检测时机。这里，仅在空调器首次上电，压缩机持续运行第一预设时长， 且运行时长小于时间阈值的情况下，进行检测。一方面，在压缩机运行时长大于或等于时间阈值时，基本上可确定截止阀开启，压缩机处于正常运行状态。因此，无需再继续检测温度参数。另一方面，空调出厂时为了保证冷媒的安全性将其封闭，在首次上电后存在冷媒截止阀未打开的情况。此外，压缩机在冷媒截止阀未开启时也不宜长时间开启，存在安全风险。时间阈值的取值范围可以为50-70分钟。
结合图3所示，本公开实施例提供另一种用于空调器的控制方法，包括：
S301，在空调器的压缩机持续运行第一预设时长的情况下，检测元件检测空调器的温度参数和空调器室外机的总电流；其中，温度参数包括一个或多个。
S302，处理器根据空调器的运行模式，确定温度参数对应的预设条件。
S303，处理器在任一温度参数满足对应的预设条件，且总电流大于电流阈值的情况下，控制压缩机停机。
S304，处理器在压缩机停机第三预设时长后，控制压缩机恢复运行；在相邻两次停机的间隔时长小于第四预设时长的情况下，不再控制压缩机恢复运行。
本公开实施例中，在满足预设条件控制压缩机停机第三预设时长后，控制压缩机恢复运转。这里，第三预设时长取值范围3-10分钟。恢复运转后继续检测相关参数，若检测参数再次符合停机控制时，再次控制压缩机停机。同时，获取先后两次停机的间隔时长，若间隔时长较短，则确定截止阀未开启，输出故障信息。这种情况下，无需再次控制压缩机恢复运行。这里，第四预设时长可取值30分钟。
结合图4所示，本公开实施例提供另一种用于空调器的控制方法，包括：
S401，在空调器的压缩机持续运行第一预设时长的情况下，检测元件检测空调器的温度参数和空调器室外机的总电流；其中，温度参数包括一个或多个。
S402，处理器根据空调器的运行模式，确定温度参数对应的预设条件。
S403，在温度参数包括多个的情况下，处理器按照预设顺序确定温度参数是否满足对应的预设条件。
S404，处理器在总电流大于电流阈值的情况下，若任一温度参数满足预设条件，则控制压缩机停机。
本公开实施例中，检查参数包括温度参数和电流参数；先判定电流参数即总电流。在总电流大于电流阈值的情况下，再判断温度参数。若任一温度参数满足对应的预设条件，则控制压缩机停机。进一步地，在温度参数包括多个时，按照预设顺序确定温度参数是否满足对应的预设条件。具体地，温度参数包括室内机盘管的温度，压缩机的吸气温度，及室外机盘管的温度和室外换热器出液端的温度。其中，预设顺序从高到低依次为压缩机的 吸气温度、室内机盘管的温度、室外机盘管的温度和室外换热器出液端的温度。即先判断压缩机的吸气温度是否满足对应的预设条件，若满足，则控制压缩机停机。若不满足，则判断室内机盘管的温度；最后再判断室外机盘管的温度和室外换热器出液端的温度。此外，室内机盘管的温度、室外机盘管的温度和室外换热器出液端的温度顺序可以相互替换，或者不分先后。这样，通过嵌套的逻辑判断顺序进行判断，有助于降低误判的可能性。
结合图5所示，本公开实施例提供一种用于空调器的控制装置50，包括检测模块21、确定模块22和控制模块23。检测模块21被配置为在空调器的压缩机持续运行第一预设时长的情况下，检测空调器的温度参数和空调器室外机的总电流；其中，温度参数包括一个或多个；确定模块22被配置为根据空调器的运行模式，确定温度参数对应的预设条件；控制模块23被配置为在任一温度参数满足预设条件，且总电流大于电流阈值的情况下，控制压缩机停机。
采用本公开实施例提供的用于空调器的控制装置，在空调器的压缩机持续运行一段时长后，检测空调器的温度参数和室外机的总电流。并根据空调器的运行模式，确定判断压缩机停机保护的预设条件。在检测温度参数满足预设条件，且总电流大于电流阈值的情况下，控制压缩机停机。这样，针对空调器不同的运行模式，设置不同的预设条件。有助于提高判断预设条件的准确性和可靠性。
结合图6所示，本公开实施例提供一种用于空调器的控制装置60，包括处理器(processor)100和存储器(memory)101。可选地，该装置还可以包括通信接口(Communication Interface)102和总线103。其中，处理器100、通信接口102、存储器101可以通过总线103完成相互间的通信。通信接口102可以用于信息传输。处理器100可以调用存储器101中的逻辑指令，以执行上述实施例的用于空调器的控制方法。
此外，上述的存储器101中的逻辑指令可以通过软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。
