空调回油控制方法、空调及计算机可读存储介质
相关申请的交叉引用
本申请要求广东美的暖通设备有限公司、美的集团股份有限公司于2018年08月15日提交的、发明名称为“空调回油控制方法、空调及计算机可读存储介质”的、中国专利申请号为“201810927936.7”的优先权。
技术领域
本申请涉及空调技术领域，尤其涉及一种空调回油控制方法、空调及计算机可读存储介质。
背景技术
随着人们生活水平的日益提高，对空调制热/制冷性能的要求也越来越高。通常，影响空调的制热/制冷性能的一个重要因素就是空调中的压缩机。
目前，空调中的压缩机还无法实现无油润滑，润滑油是对压缩机内运动部件之间起润滑作用的物质，如果压缩机缺少润滑油，压缩机电机轴承和压缩腔将得不到有效润滑，从而摩擦加剧会导致压缩机损坏。因此，空调润滑油的回收对于空调可靠运行具有至关重要的作用。
然而，现有的空调基本上都是以累计本次运行的运行时间作为回油触发条件，这种控制方式有一定的弊端，例如，在保安室、小型机房等24小时只开一台室内机时，采用该控制方式会造成对应的室外机低频频繁启停，或者三管制空调在20度附近时模式频繁切换使得室外机频繁启停，使得室外机累计运行时间达不到回油触发条件，造成压缩机润滑不足，导致压缩机缺油烧毁。

在本实施例中，空调回油控制方法包括以下步骤：
步骤S100，在检测到所述室外机当前的上电运行状态满足预设条件、且上电运行后的持续时长达到第一预设时长时，控制所述室外机执行回油操作，并将所述室外机的启停操 作对应的启停次数设置为初始值；
本实施例中的室外机可以为多联机系统中一个或多个室外机中的任意一个。其中，初始值可以进行合理设置，例如该初始值可设置为0，将启停次数设置为初始值即为将该启停次数清零。第一预设时长也可进行合理设置，例如该第一预设时长可设置为10分钟、30分钟等，本实施例中不做限定。
可通过室外机的运行数据确定室外机当前的上电运行状态是否满足预设条件，具体地，通过室外机的运行数据确定当前上电运行之前，室外机的前一次停机操作为正常停机操作时，该室外机当前的上电运行状态满足预设条件，例如，室外机的前一次停机操作为提高遥控器等控制指令控制室外机停机时，该停机操作为正常停机操作，而对于室外机频繁启停时的停机操作以及室外机因断电而停机的停机操作均为非正常停机操作，即若室外机的前一次停机操作为室外机频繁启停时的停机操作、室外机因断电而停机的停机操作，则室外机当前的上电运行状态不满足预设条件。
在本实施例中，若检测到空调的室外机上电运行、且当前的上电运行状态满足预设条件，则实时累计该室外机上电运行后的持续时长，并在室外机上电运行后的持续时长达到第一预设时长时，控制室外机执行回油操作，并将室外机的启停操作对应的启停次数设置为初始值。
启停操作是指室外机从运行状态至停止运行状态、并从停止运行状态再次到运行状态的过程中，室外机所执行的操作，室外机历经一次从运行状态至停止运行状态、并从停止运行状态再次到运行状态的过程，记为一次启停，即启停次数加一。
需要说明的是，室外机包括压缩机、以及与压缩机相连通的油分离器，在室外机正常运行时，压缩机与油分离器断开，在室外机执行回油操作时，压缩机与油分离器连通，以使油分离器中的润滑油流至压缩机，优选地，可在压缩机与油分离器之间的连通管路中设置控制开关，在室外机执行回油操作时，通过控制该控制开关使压缩机与油分离器连通，并在回油操作完成时，通过控制该控制开关使压缩机与油分离器断开。优选地，室外机还包括电子膨胀阀，该电子膨胀阀的一端与所述油分离器相连通，另一端与压缩机相连通，在室外机执行回油操作时，通过调节该电子膨胀阀的开度使压缩机与油分离器连通，并在回油操作完成时，通过调节该电子膨胀阀的开度使压缩机与油分离器断开。
步骤S200，在所述回油操作完成时，实时检测所述室外机是否存在启停操作；
在本实施例中，在回油操作完成时，实时监测室外机当前的运行数据，已根据室外机当前的运行数据确定室外机是否存在启停操作，其中，该启停操作包括室外机的频繁启停、因断电而触发的室外机启停、因室外机的强制制冷回油操作或化霜操作引起的室外机启停。
步骤S300，在所述室外机存在启停操作时，更新所述启停次数；
步骤S400，在更新后的启停次数达到预设次数、且所述室外机当前处于启动运行状态时，控制所述室外机执行回油操作。
其中，预设次数可以进行合理设置，例如，可将该预设次数设置为15、20、30等。
在本实施例中，在确定室外机当前存在启停操作时，更新该启停操作对应的启停次数，具体地，将当前的启停次数加一作为新的启停次数；若更新后的启停次数达到预设次数，则在室外机当前处于启动运行状态时，控制该室外机执行回油操作，以使油分离器内的润滑油回流至室外机的压缩机，以实现根据室外机的启停次数进行压缩机的回油，避免现有的回油方式中因室外机的运行时间达不到回油的触发条件而无法及时回油，使得压缩机润滑不足，甚至导致压缩机缺油烧毁的问题，进而有效解决压缩机的润滑油不足的问题，提高了室外机的使用寿命。
进一步地，在一实施例中，在步骤S400之后，该空调回油控制方法还包括：在所述回油操作完成时，将所述启停次数设置为初始值，并继续执行实时检测所述室外机是否存在启停操作的步骤。
在本实施例中，在室外机回油完成时，将启停次数设置为初始值，并实时检测所述室外机是否存在启停操作，继续累计室外机的启停次数，并判断新的启停次数是否满足室外机回油的触发条件，即新的启停次数是否达到预设次数，进而能够持续根据室外机的启停次数进行回油操作，以避免压缩机的润滑油不足的问题，进一步提高了室外机的使用寿命。
本实施例提出的空调回油控制方法，通过在检测到所述室外机当前的上电运行状态满足预设条件、且初次上电运行后的持续时长达到第一预设时长时，控制所述室外机执行回油操作，并将所述室外机的启停操作对应的启停次数设置为初始值，接着在所述回油操作完成时，实时检测所述室外机是否存在启停操作，而后在所述室外机存在启停操作时，更新所述启停次数，然后在更新后的启停次数达到预设次数、且所述室外机当前处于启动运行状态时，控制所述室外机执行回油操作，实现了根据室外机的启停次数进行室外机的回油，避免现有的回油方式中因室外机的运行时间达不到回油的触发条件而无法及时回油，使得压缩机润滑不足，甚至导致压缩机缺油烧毁的问题，进而有效解决压缩机的润滑油不足的问题，提高了室外机的使用寿命。
基于第一实施例，提出本申请空调回油控制方法的第二实施例，参照图3，在本实施例中，步骤S400包括：
步骤S410，在更新后的启停次数达到预设次数、且所述室外机当前处于启动运行状态 时，确定更新后的启停次数对应的首次启停时刻与末次启停时刻；

其中，该第二预设时长可进行合理设置，且该第二预设时长大于第一预设时长；例如，该第二预设时长可设置为2小时、3小时等，本实施例中不做限定。

若计算得到的时间间隔小于或等于第二预设时长，则控制室外机执行回油操作，进而出现室外机在短时间内频繁启停的情况时，室外机能够及时回油，进而有效解决压缩机的润滑油不足的问题，提高了室外机的使用寿命。
需要说明的是，若时间间隔大于第二预设时长，则计算更新后的启停次数中各个启停时刻与末次启停时刻之间的时长，根据得到的多个时长确定，小于第二预设时长的时长对应的启停时刻，根据更新后的启停次数确定该启停时刻之后的剩余启停次数，将该剩余启停次数作为新的启停次数，并继续执行实时检测所述室外机是否存在启停操作的步骤。
本实施例提出的空调回油控制方法，通过在更新后的启停次数达到预设次数、且所述室外机当前处于启动运行状态时，确定更新后的启停次数对应的首次启停时刻与末次启停时刻，接着计算所述首次启停时刻与末次启停时刻之间的时间间隔，而后在所述时间间隔小于或等于第二预设时长时，控制所述室外机执行回油操作，实现了在室外机在第二预设时长内发生频繁启停的情况时进行室外机的回油，使得室外机能够及时回油，进而有效解决压缩机的润滑油不足的问题，提高了室外机的使用寿命。

其中，若当前室外机的启停操作为非断电启停操作时，则更新所述启停次数，此时该启停操作可能为室外机频繁启停操作。
进一步地，在一实施例中，在步骤S310之后，还包括：在当前所述室外机的启停操作为断电启停操作时，将所述启停次数设置为初始值，并继续执行所述在检测到空调的室外机上电运行的持续时长达到第一预设时长时，控制所述室外机执行回油操作的步骤。
在本实施例中，若当前所述室外机的启停操作为断电启停操作，当前该室外机为断电后再次上电运行，因此将所述启停次数设置为初始值，并在检测到空调的室外机上电运行的持续时长达到第一预设时长时，控制所述室外机执行回油操作，实现室外机在断电启动后及时回油，使得室外机能够及时回油，进而有效解决压缩机的润滑油不足的问题，进一步提高了室外机的使用寿命。
本实施例提出的空调回油控制方法，通过在所述室外机存在启停操作时，确定当前所述室外机的启停操作是否为断电启停操作操作，接着在当前所述室外机的启停操作为非断电启停操作时，更新所述启停次数，进而能够排除断电启停操作，提高了启停次数的准确性，进而提高根据启停次数进行室外机回油的准确性，进一步提高了室外机的使用寿命。
基于第三实施例，提出本申请空调回油控制方法的第四实施例，参照图5，在本实施例中，步骤S320包括：
步骤S321，在当前所述室外机的启停操作为非断电启停操作时，确定当前所述室外机的启停操作是否是强制制冷操作或化霜操作；
步骤S322，在当前所述室外机的启停操作不是强制制冷回油操作、且不是化霜操作时，更新所述启停次数。
在本实施例中，若当前所述室外机的启停操作为非断电启停操作，则确定当前所述室外机的启停操作是否是强制制冷操作或化霜操作，即当前的启停操作是否是由于接收到强制制冷指令或化霜指令而引起的，并在当前所述室外机的启停操作不是强制制冷回油操作、且不是化霜操作时，更新所述启停次数，进而能够排除强制制冷操作以及化霜操作，提高了启停次数的准确性，进而提高根据启停次数进行室外机回油的准确性，进一步提高了室外机的使用寿命。
进一步地，在一实施例中，在步骤S321之后，还包括：在当前所述室外机的启停操 作为强制制冷回油操作或化霜操作时，将所述启停次数设置为初始值，并继续执行实时检测所述室外机是否存在启停操作的步骤。
在本实施例中，若当前所述室外机的启停操作为强制制冷回油操作或化霜操作，即当前的启停操作是由于接收到强制制冷指令或化霜指令而引起的，将所述启停次数设置为初始值，并实时检测所述室外机是否存在启停操作，进而在强制制冷回油操作或化霜操作后，继续累计室外机的启停次数，并判断新的启停次数是否满足室外机回油的触发条件，即新的启停次数是否达到预设次数，进而能够持续根据室外机的启停次数进行回油操作，以避免压缩机的润滑油不足的问题，进一步提高了室外机的使用寿命。
本实施例提出的空调回油控制方法，通过在当前所述室外机的启停操作为非断电启停操作时，确定当前所述室外机的启停操作是否是强制制冷操作或化霜操作，接着在当前所述室外机的启停操作不是强制制冷回油操作、且不是化霜操作时，更新所述启停次数，进而能够排除强制制冷操作以及化霜操作，提高了启停次数的准确性，进而提高根据启停次数进行室外机回油的准确性，进一步提高了室外机的使用寿命。同时，由于室外机在执行强制制冷回油操作或化霜操作后，已经完成回油，因此无需再次根据启停次数回油，提高了室外机回油的效率。
基于上述实施例，提出本申请空调回油控制方法的第五实施例，参照图6，在本实施例中，步骤S400包括：
步骤S500，实时更新所述室外机的运行时长；
步骤S600，在所述运行时长达到第三预设时长时，控制所述室外机执行回油操作，其中，所述第三预设时长大于所述第一预设时长；
步骤S700，将所述启停次数设置为初始值，并继续执行所述实时检测所述室外机是否存在启停操作的步骤。
其中，该第三预设时长可进行合适设置，例如该第三预设时长可设置为5小时、8小时等；该第三预设时长大于第一预设时长，优选地，该第三预设时长大于第二预设时长。
在本实施例中，在控制室外机执行回油操作之后，实时累计室外机的运行时长，具体地，在存在室外机的启停操作，根据室外机停机之前累计的运行时长继续累计，并在运行时长达到第三预设时长时，控制室外机执行回油操作，将所述启停次数设置为初始值，以实现室外机的累计运行时长达到该第三预设时长时，室外机能够及时回油，进而有效解决压缩机的润滑油不足的问题，提高了室外机的使用寿命。
通过实时检测所述室外机是否存在启停操作，判断新的启停次数是否满足室外机回油 的触发条件，即新的启停次数是否达到预设次数，进而能够持续根据室外机的启停次数进行回油操作，以避免压缩机的润滑油不足的问题，进一步提高了室外机的使用寿命。
本实施例提出的空调回油控制方法，通过实时更新所述室外机的运行时长，接着在所述运行时长达到第三预设时长时，控制所述室外机执行回油操作，而后将所述启停次数设置为初始值，并继续执行所述实时检测所述室外机是否存在启停操作的步骤，能够根据室外机的运行时长控制室外机进行回油操作，进而室外机能够及时回油，有效解决压缩机的润滑油不足的问题，进一步提高了室外机的使用寿命。
