Description

用于多联机空调控制的方法及装置、多联机空调、存储介质
本申请基于申请号为202211255380.4、申请日为2022年10月13日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及智能家电技术领域，例如涉及一种用于多联机空调控制的方法及装置、多联机空调、存储介质。
背景技术
多联机空调的超配比为所有室内机负荷之和与室外机负荷之比。为了节省成本，在选型安装时超配比一般会建议在120％～150％。在此种情况下，通常不建议用户开机负荷超过100％，若用户同时开启的室内机超过限定比例，则不启动室外机。这样，给用户带来使用效果体验差，甚至会出现抱怨投诉。
相关技术公开了一种多联机空调的控制方法，包括：接收开启目标待机室内机的指令；判断目标待机室内机是否满足开机条件，其中，开机条件包括Q内:Q外≤K，Q内为目标待机室内机的负荷与所有运行中室内机的负荷之和，Q外为室外机的负荷，K为配额系数；若目标待机室内机满足开机条件，则控制目标待机室内机开机；若目标待机室内机不满足开机条件，则控制目标待机室内机进入等待队列，直至目标待机室内机在满足开机条件的情况下开机。
在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：
该技术虽然能够实现在装配多联机空调时，不用限制多联机空调的超配比，也不会出现同时运行的室内机过多，超出室外机的负荷能力的问题。但是相关技术在超负荷开机的情况下，目标室内机需待机等待按待机先后顺序运行，无法按需求进行控制。因此，相关技术在多联机空调超配且室内机超负荷开机的情况下，室内机运行控制的灵活性差。
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本申请的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。

多联机空调通常选择超配配置，即多联机空调所有室内机负荷之和大于室外机额定负荷。
本公开实施例提供一种多联机空调，包括多个室内机、室外机和处理器。处理器可以对多个室内机的运行进行控制。在超负荷开机的情况下，处理器可以对新开机运行的室内机和正在运行的室内机的运行或待机进行控制，并且可以对待机室内机的运行顺序进行控制。多联机空调在运行过程中，部分室内机处于运行状态，其余室内机处于待机状态或关机状态。
结合上述的多联机空调，本公开实施例提供一种用于多联机空调控制的方法。如图1所示，该方 法包括：
S101，处理器接收第一目标室内机的开机运行指令。
第一目标室内机为用户正在开机需求运行的一个室内机。例如，A用户使用遥控器打开所在房间的室内机，并设置为制热运行26℃。此时，处理器可以接收第一目标室内机的开机制热运行指令。
S102，在室内机的总运行负荷小于或等于室外机的运行负荷的情况下，处理器按指令运行第一目标室内机。
多联机空调在部分室内机处于运行状态的情况下，其余室内机处于待机状态或关机状态。在室内机存在待机室内机的情况下，室内机的总运行负荷为运行室内机的负荷、待机室内机的负荷和第一目标室内机的负荷之和。在室内机不存在待机室内机的情况下，室内机的总运行负荷为运行室内机的负荷和第一目标室内机的负荷之和。室外机的运行负荷为室外机的额定负荷。室内机的总运行负荷小于或等于室外机的运行负荷说明第一目标室内机运行后，不会出现超负荷运行的情况，因此在此种情况下可以按指令运行第一目标室内机。
S103，在室内机的总运行负荷大于室外机的运行负荷的情况下，处理器判断第一目标室内机的优先级是否大于或等于优先级阈值，如果是则处理器按指令运行第一目标室内机并将第二目标室内机中的一台或多台室内机调整为待机；其中，第二目标室内机为运行中的低优先级室内机。
室内机的总运行负荷大于室外机的运行负荷说明第一目标室内机运行后，会出现超负荷运行的情况，因此在此种情况下不可以直接按指令运行第一目标室内机。室内机的优先级为提前设定的。例如，利用室内机内机编码对室内机的优先级进行设定，内机编码越小优先级越高。不同的室内机设置不同的内机编码。优先级阈值可以根据用户的需求进行设置。例如，可以设置优先级阈值为内机编码为4的室内机的优先级。那么，内机编码为1、2、3的室内机的优先级大于优先级阈值。低优先级室内机为优先级小于优先级阈值的室内机。或者，低优先级室内机为优先级小于第一目标室内机的优先级的室内机。
本公开实施例中，在室内机超负荷开机的情况下，第一目标室内机可以根据室内机的优先级进行运行。同时，需要将运行中部分低优先级的室内机待机，以避免超负荷运行。优先级代表了用户的优先需求。相关技术在室内机超负荷开机的情况下，第一目标室内机需待机等待，并按待机先后顺序运行。与相关技术相比，本方法能够在多联机空调超配且室内机超负荷开机的情况下，提高室内机运行控制的灵活性。
可选地，在处理器将第二目标室内机中的一台或多台室内机调整为待机前，该方法还包括：处理器按第二目标室内机中室内机的优先级从低到高的顺序，累加第二目标室内机中的一台或多台室内机的运行负荷，直至累加的运行负荷大于或等于第一目标室内机的运行负荷。处理器将第二目标室内机中的一台或多台室内机确定为需要待机的室内机。例如，第二目标室内机有4台，内机编码分别为7、8、9、10。内机编码越小，优先级越高。那么，从内机编码为10的室内机的运行负荷开始依次累加。每累加一次与第一目标室内机的运行负荷进行比较，在累加的运行负荷开始大于或等于第一目标室内机的运行负荷的情况下，停止累加。例如，第一目标室内机的运行负荷为3500W，内机编码为10的室内机的运行负荷为2500W，内机编码为9的室内机的运行负荷为2500W。那么，内机编码为10的室内机和内机编码为9的室内机的运行负荷累加已经大于第一目标室内机的运行负荷。因此，将内机编码为10的室内机和内机编码为9的室内机确定为需要待机的室内机。这样，优先运行优先级高的室内机，将优先级最低的室内机待机。在避免多联机空调超负荷运行的情况下，可以保证用户优先级需求高的室内机优先运行。从而，能够在多联机空调超配且室内机超负荷开机的情况下，提高了室内机运行控制的灵活性，提高了用户体验。
结合图2所示，本公开实施例提供另一种用于多联机空调控制的方法，包括：
S201，处理器接收第一目标室内机的开机运行指令。
S202，在室内机的总运行负荷大于室外机的运行负荷的情况下，处理器判断第一目标室内机的优先级是否大于或等于优先级阈值，如果是则处理器按第二目标室内机中室内机的优先级从低到高的顺序，累加第二目标室内机中的一台或多台室内机的运行负荷，直至累加的运行负荷大于或等于第一目标室内机的运行负荷。
S203，处理器将第二目标室内机中的一台或多台室内机确定为需要待机的室内机。
S204，处理器按指令运行第一目标室内机并将第二目标室内机中的一台或多台室内机调整为待机。
其中，第二目标室内机为运行中的低优先级室内机。
本公开实施例中，在室内机超负荷开机的情况下，第一目标室内机可以根据室内机的优先级进行运行。同时，需要将运行中部分低优先级的室内机待机，以避免超负荷运行。优先级代表了用户的优先需求。优先运行优先级高的室内机，将优先级最低的室内机待机。在避免多联机空调超负荷运行的情况下，可以保证用户优先级需求高的室内机优先运行。从而，能够在多联机空调超配且室内机超负荷开机的情况下，提高了室内机运行控制的灵活性，提高了用户体验。
可选地，在第一目标室内机的优先级小于优先级阈值的情况下，该方法还包括：处理器根据第一目标室内机的室内环境温度、目标温度和运行负荷确定第一目标室内机运行或待机。室内环境温度为室内机所在房间的实时环境温度，目标温度为室内机的设定温度。这样，在第一目标室内机优先级低的情况下，根据第一目标室内机的室内环境温度、目标温度和运行负荷可以确定是否运行第一目标室内机，较高程度保证用户的舒适度。从而，能够在多联机空调超配且室内机超负荷开机的情况下，提高了室内机运行控制的灵活性，提高了用户体验。

本公开实施例中，在室内机超负荷开机的情况下，第一目标室内机可以根据室内机的优先级进行运行。同时，需要将运行中部分低优先级的室内机待机，以避免超负荷运行。优先级代表了用户的优先 需求。优先运行优先级高的室内机，将优先级最低的室内机待机。在避免多联机空调超负荷运行的情况下，可以保证用户优先级需求高的室内机优先运行。在第一目标室内机优先级低的情况下，根据室内环境温度和目标温度确定需要待机的第三目标室内机，可以优先运行第一目标室内机，较高程度保证用户的舒适度。从而，能够在多联机空调超配且室内机超负荷开机的情况下，提高了室内机运行控制的灵活性，提高了用户体验。
可选地，处理器根据第二目标室内机的室内环境温度和目标温度确定第三目标室内机包括：处理器计算ΔTmi＝∣Tao-mi-Tset-mi∣，获得第二目标室内机中第i台室内机的温差绝对值。处理器判断ΔTmi是否小于或等于T2，获得温差绝对值小于或等于T2的室内机。处理器将所有温差绝对值小于或等于T2的室内机确定为第三目标室内机。其中，Tao-mi为第二目标室内机中第i台室内机的室内环境温度，Tset-mi为第二目标室内机中第i台室内机的目标温度，i＝1，...，n，n为第二目标室内机的数量；T2为第二温度差阈值。这样，通过判断出室内环境温度和目标温度的温度差小于或等于一定值的室内机并从中可以进一步确定出待机的室内机。温度差小于或等于一定值的室内机待机不会使用户感受到不适，同时，还可以优先运行温度差较大的第一目标室内机。从而，能够在多联机空调超配且室内机超负荷开机的情况下，提高了室内机运行控制的灵活性，提高了用户体验。

可选地，在存在待机室内机的情况下，该方法还包括：处理器对所有待机室内机按待机运行优先级高低规则进行排序。在满足待机室内机运行条件的情况下，处理器按待机运行优先级从高到低的顺序运行待机室内机。待机运行优先级指在满足待机室内机运行条件的情况下，所有待机室内机运行的先后顺序，先运行的代表待机运行优先级高，后运行的代表待机运行优先级低。这样，在室内机超负荷开机 的情况下，在满足待机室内机运行条件的情况下，可以按待机室内机的运行优先级顺序从高到低运行。运行优先级代表了用户的优先运行需求。相关技术在室内机超负荷开机的情况下，室内机在待机等待后，需按待机先后顺序运行。与相关技术相比，本方法能够在多联机空调超配且存在待机室内机的情况下，按照用户需求情况运行，提高了待机室内机运行控制的灵活性。
