Description

用于控制空调的方法、装置和多联机空调
本申请基于申请号为202111560563.2、申请日为2021年12月20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
本申请涉及智能空调技术领域，例如涉及一种用于控制空调的方法、装置和多联机空调。
背景技术
目前，一个家庭中的不同房间均可安装空调，这些空调可以是多联机空调，还可以分体式空调，每个空调可调节其所处房间的温度。在调节家庭内温度的过程中，可设定一个设定温度，将室内温度高于设定温度的房间确定为制冷房间，如果制冷房间中的空调处于制热模式，则将制冷房间中的空调的运行模式切换为制冷模式，这样，可以将家庭中多个房间的温度均调节至目标温度。
对于每个房间的空调，采用具有消除偏差功能的控制器进行控制，即，首先确定室内温度与设定温度的温度差值，再依据该温度差值确定空调的制冷功率或制热功率，并且，温度差值越大，则制冷功率或制热功率越大。
在实现本申请实施例的过程中，发现相关技术中至少存在如下问题：
温度差值越大，则制冷功率或制热功率越大，可在一定程度上缩短室内温度达到设定温度所需时长，但在家庭中的两个房间之间通常存在门窗，在门窗打开的情况下，两个房间之间存在热交换，热量由温度较高的房间流向温度较低的房间，并且，两个房间的温度差值越大，热量流动越大。由于两个房间的体积以及两个房间的空调的参数各不相同，对两个房间的空调分别采用传统控制方法进行控制的过程中，两个房间独立升温或独立降温，将导致两个房间之间的热量流动不均匀，进而导致两个房间的升温过程或降温过程的稳定性较差，最终导致两个房间的室内温度达到设定温度时的稳定性较差。可见，在对存在热交换的两个房间同时升温或降温的情况下，现有控制方法无法兼顾温度调节速率和两个房间的温度达到设定温度时的稳定性。

本申请实施例提供的用于控制空调的方法、装置和智能空调，可以实现以下技术效果：
第一温度差值小于第二温度差值，即，在两个房间同时升温的情况下，第一室内温度高于第二室内温度；在两个房间同时降温的情况下，第一室内温度低于第二室内温度；这种情况下，如果第一温度差值大于第一温度阈值，则表示第一室内温度和第二室内温度与设定温度之间的差值比较大，此时按照独立的控制策略控制第一空调和第二空调，例如以比例-积分-微分(Proportion Integral Differential，PID)为代表的具有消除偏差功能的控制器，均可使第二控制策略对应的平均室温变化速率大于第一控制策略对应的平均室温变化速率，此时可以使第二房间快速升温；在第一温度差值小于或等于第一温度阈值的情况下，表示第一室内温度和第二室内温度与设置温度的差值较小，此时采用一种控制策略(第三控制策略)对第一空调和第二空调进行控制，使第一房间在第一空调的调节作用下的温度变化速率，和第二房间在第二空调的调节作用下的温度变化速率趋近于相同，在这个阶段中，缓解或消除了前一个阶段中室内温度对空调的调温功率滞后，最终使第一室内温度和第二室内温度的温度差值趋近于稳定，进而使得第一房间的和第二房间的热量流动变得均匀，此时对于室内温度高的房间内空调而言，其调温功率(制冷功率或制热功率)一方面维持本房间的温度变化，另一方面抵消流向室内温度低的房间的热量，由于流向室内温度低的房间的热量流量稳定，可以使室内温度高的房间内的空调稳定地调节本房间的室内温度；同样地，对于室内温度低的房间内空调而言，其调温功率一方面维持本房间的温度变化，另一方面抵消来自室内温度高的房间的热量，由于来自室内温度高的房间的热量流量稳定，可以使室内温度低的房间内的空调稳定地调节本房间的室内温度，这样提高了升温或降温过程中的室内温度的稳定性，有利 于提高两个房间的室内温度达到设定温度时的稳定性。

图1是本申请实施例提供的一种用于控制空调的方法的实施场景的示意图。该实施场景包括第一房间R1和第二房间R2，第一房间R1中安装有第一空调K1，第一空调K1可调节第一房间R1内的第一室内温度T1，第二房间R2中安装有第二空调K2，第二空调K2可调节第二房间R2内的第二室内温度T2，第一房间R1和第二房间R2可通过通道P进行热交换，该通道P可以是打开的门，或者是打开的窗户，或者是打开的门和窗户。在第一室内温度T1高于第二室内温度T2的情况下，热量由第一房间R1经过通道P流向第二房间R2，使第一室内温度T1具有降低趋势，使第二室内温度T2具有升高趋势；在第一室内温度T1低于第二室内温度T2的情况下，热量由第二房间R2经过通道P流向第一房间R1，使第一室内温度T1具有降低趋势，使第二室内温度T2具有升高趋势。
可通过门和/或窗开启状态检测装置检测通道P是否打开，例如，在门和/或窗上安装关到位传感器， 利用关到位传感器的检测信号确定门和/或窗的开启状态，以判断第一房间R1和第二房间R2是否存在热交换。
另外，在其他应用场景中，例如在办公室的应用场景中，第一房间和第二房间可以是通过走廊连通的两个房间，或者，通过隔断隔开的两个房间，这样的第一房间和第二房间的热量流动性更强。
本申请实施例提供了一种用于控制空调的方法，该方法对房间的升温过程或降温过程进行了分段处理，在第一房间的第一室内温度以及第二房间的第二温度均偏离设定温度较大时，由第一空调对第一房间进行自由升温或降温，以及由第二空调对第二房间进行自由升温或降温，此时第一室内温度与设定温度的差值、第二室内温度与设定温度的差值均比较大，第一房间以及第二房间均可比较快地升温/降温；随着第一室内温度以及第二室内温度临近设定温度，再使两个房间的室温变化速率趋近于相同，这样，第一室内温度以及第二室内温度之间的差值可维持不变，第一房间和第二房间之间的热量流动比较稳定，使第一房间和第二房间的升温过程/降温过程比较平稳，有利于第一房间和第二房间比较稳定地分别达到设定温度。
图2是本申请实施例提供的一种用于控制空调的方法的流程示意图。该用于控制空调的方法可由空调的控制器执行，或者，由与空调通信连接的控制面板或遥控器执行，或者，由智能家居系统的服务器执行。本申请实施例以将该用于控制空调的方法控制图1中所示的第一空调和第二空调为例，对该用于控制空调的方法进行示例性说明。
结合图2所示，用于控制空调的方法包括：
S201、在对存在热交换的第一房间和第二房间同时升温或降温的情况下，获得第一房间的第一室内温度、第二房间的第二室内温度，以及第一房间和第二房间的设定温度。
在家庭或办公室场景中，通常需要平衡各个房间的温度，即，将各个房间的室内温度均调整至同一个设定温度，以提高用户舒适度。
第一房间的第一室内温度或第二房间的第二室内温度均未达到设定温度的情况可包括：第一室内温度和第二室内温度均大于设定温度，此时需要对第一房间和第二房间进行同时降温处理；或者，第一室内温度和第二室内温度均小于设定温度，此时需要对第一房间和第二房间进行同时升温处理；或者，在第一室内温度和第二室内温度中，一个室内温度大于设定温度，另一个室内温度小于设定温度，此时需要对一个房间进行升温处理，对另外一个房间进行降温处理。
本申请实施例提供的用于控制空调的方法，适用于第一室内温度和第二室内温度同时大于或小于设定温度的情况。
S202、获得设定温度与第一室内温度之间的第一温度差值，以及设定温度与第二室内温度之间的第二温度差值。
在本申请实施例中，为便于说明，使第一温度差值和第二温度差值以正值的形式存在，例如，在第一房间和第二房间同时升温的情况下，可用设定温度减去第一室内温度以获得第一温度差值，用设定温度减去第二室内温度以获得第二温度差值；在第一房间和第二房间同时降温的情况下，可用第一室内温度减去设定温度以获得第一温度差值，用第二室内温度减去设定温度以获得第二温度差值。
当然，第一温度差值以及第二温度差值以正值的形式存在，仅为了便于说明，在实际应用中，通常 以设定温度减去第一室内温度以获得第一温度差值，以设定温度减去第二室内温度以获得第二温度差值。
为便于说明，本申请实例中的第一温度差值小于第二温度差值，在第一房间和第二房间同时升温的情况下，第一室内温度高于第二室内温度；在第一房间和第二房间同时降温的情况下，第一室内温度低于第二室内温度。
S203、在第一温度差值大于第一温度阈值的情况下，根据第一控制策略控制第一房间的第一空调，以及根据第二控制策略控制第二房间的第二空调。
首先对第一温度阈值进行详细说明：
第一温度差值可用于表示第一室内温度偏离设定温度的偏离程度，第一温度阈值可用于对第一室内温度偏离设定温度的偏离程度进行分类。例如，在第一温度差值大于第一温度阈值的情况下，可表示第一室内温度偏离设定温度的程度较高，在第一温度差值小于或等于第一温度阈值的情况下，可表示第一室内温度偏离设定温度的程度较低。
进一步地，第一温度阈值可按照如下方式确定：获得第一房间的体积与第一空调的调温功率的第一体积功率比，以及第二房间的体积与第二空调的调温功率的第二体积功率比；在第一体积功率比和第二体积功率比中确定出较大的体积功率比；获得与较大的体积功率比正相关的第一温度阈值。
本申请实施例中的调温功率，指的是空调的制热功率或制冷功率，例如，空调压缩机的运行频率越快，则该空调的调温功率越大；空调室内机的风机转速越大高，则该空调的调温功率越大。一个空调的调温功率越大，该空调所在房间的室温变化速率越大。
第一体积功率比可用于表示第一室内温度相对于第一空调的调温功率的滞后，第一体积功率比越大，第一空调的调温功率变化后，第一室内温度响应第一空调的调温功率变化所需的时间越长，在第一房间的室内变化过程中，不稳定变化的温度的跨度越大；第一体积功率比越小，第一空调的调温功率变化后，第一室内温度响应第一空调的调温功率变化所需的时长越短，不稳定变化的温度的跨度越小。同样地，第二体积功率比可用于表示第二室内温度相对于第二空调的调温功率的滞后。
第一温度阈值与较大的体积功率比正相关，在对应于较大的体积功率比的空调的调温功率变化后，该空调所在房间的室内温度达到设定温度之前，该房间内的室内温度可稳定变化(稳定升温或稳定降温)，有利于该房间内的室内温度可稳定地达到设定温度；同时，利用上述方式对第一调温阈值进行限定，可尽可能的减小第一温度阈值，以提高第一房间和第二房间快速升温/降温的时长，可以使第一室内温度和第二室内温度更快地达到设定温度。
以下再对第一控制策略以及第二控制策略进行详细说明：
第一控制策略和第二控制策略均对应平均室温变化速率，第一控制策略对应的平均室温变化速率，指的第一空调在第一控制策略的控制下，使第一房间的温度升高的平均速率，或者，使第一房间的温度降低的平均速率；对应地，第二控制策略对应的平均室温变化速率，指的是第二空调在第二控制策略的控制下，使第二房间的温度升高的平均速率，或者，使第二房间的温度降低的平均速率。
第一控制策略可为使第一房间的第一室内温度按照第一室温变化速率进行变化，第二控制策略可为使第二房间的第二室内温度按照第二室温变化速率进行变化，其中，第一室温变化速率小于第二室温变 化速率。
或者，第一控制策略和第二控制策略可均为PID控制器或线性二次型调节器(Linear Quadratic Regulator，LQR)或其他具有偏差消除偏差功能的控制策略。第一温度差值小于第二温度差值，第一控制策略对应的平均温度变化速率小于第二控制策略对应的温度变化速率，第一房间和第二房间均可以快速地升温或降温，即，第一温度差值和第二温度差值均可快速地减小。
可选地，根据第一控制策略控制第一房间的第一空调，根据第二控制策略控制第二房间的第二空调，包括：根据温度差值与调温功率的对应关系，确定与第一温度差值对应的第三调温功率；根据温度差值与调温功率的对应关系，确定与第二温度差值对应的第四调温功率；根据第三调温功率控制第一空调，根据第四调温功率控制第二空调。
这里的温度差值调温功率的对应关系，可采用对应数据表来表示，该对应数据表存储在数据库中，在获得第一温度差值以及第二温度差值后，通过查询数据库，即可获得与第一温度差值对应的第三调温功率，以及与第二温度差值对应的第四调温功率。
或者，温度差值与调温功率的对应关系，是以控制算法的形式存在的，在控制算法中，温度差值为输入量，调温功率为输出量。这样，在获得第一温度差值和第二温度差值后，将第一温度差值输入至控制算法中，可获得控制算法输出的与第一温度差值对应的第三调温功率，将第二温度差值输入至控制算法中，可获得控制算法输出的与第二温度差值对应的第四调温功率。
这里的控制算法可以是PID控制算法、LQR控制算法或其他具有偏差消除功能的控制算法。
根据第三调温功率控制第一空调，可包括：利用第三调温功率对应的压缩机频率和/或室内风机转速控制第一空调；根据第四调温控制第二空调，可包括：利用第四调温功率对应的压缩机频率和/或室内风机转速控制第二空调。
通过上述方式，可使第一空调按照第一控制策略运行，第二空调按照第二控制策略运行。
S204、在第一温度差值小于或等于第一温度阈值的情况下，根据第三控制策略控制第一房间的第一空调和第二房间的第二空调。
其中，第三控制策略对应的平均室温变化速率小于或等于第一控制策略对应的平均室温变化速率，并且，在第三控制策略的控制下，第一房间的室温变化速率和第二房间的室温变化速率趋近于相同。
以下对第三控制策略进行详细说明：
第三控制策略可为使第一室内温度和第二室内温度均按照第三室温变化速率进行变化，第三室温变化速率小于或等于第一室温变化速率。
或者，根据第三控制策略控制第一房间的第一空调和第二房间的第二空调，可包括：获得第二温度差值与第一温度差值之间的第三温度差值；根据设定温度差值与第三温度差值之间的第四温度差值，调节第一空调以及第二空调的调温功率，使第四温度差值趋近于零。
第四温度差值趋近于零，指的是第四温度差值始终具有变化为零的趋势，在实际应用中，第四温度差值在零附近波动，第四温度差值可以大于零，第四温度差值还可以小于零；或者，在第四温度差值在-1℃～1℃范围内(可包括端点值)波动时，确定第四温度差值趋近于零。
设定温度差值越大，则第一室内温度和第二室内温度达到设定温度时容易产生的较大波动；设定温 度差值越小，则第一室内温度和第二室内温度达到设定温度时不容易产生较大波动。这里对设定温度差值不做具体限定，本领域技术人员可根据实际需求确定合适的设定温度差值。
另外，设定温度差值还可以是第一温度差值等于第一温度阈值时，第一室内温度和第二室内温度的差值。这样，在根据第三控制策略控制第一空调和第二空调时，有利于缩短第一室内温度和第二室内温度由波动变化(波动升温或波动降温)至稳定变化(稳定升温或稳定降温)所需的稳定时长，确保在第一室内温度和第二室内温度达到设定温度之前，第一室内温度和第二室内温度可稳定变化，第一室内温度和第二室内温度之间的第三温度差值可维持稳定，第一房间和第二房间的热量流动维持稳定，使第一室内温度和第二室内温度可稳定地达到设定温度。
进一步地，根据设定温度差值与第三温度差值之间的第四温度差值，调节第一空调以及第二空调的调温功率，可包括：根据温度差值与调温功率的对应关系，确定与第一温度差值对应的第一调温功率；根据温度差值与调温功率的对应关系，确定与第二温度差值对应的第二调温功率；根据第四温度差值调整第一调温功率和/或第二调温功率；调整后的第一调温功率用于控制第一空调，调整后的第二调温功率用于控制第二空调。
这里的温度差值与调温功率的对应关系，可采用对应数据表来表示，该对应数据表存储在数据库中，在获得第一温度差值以及第二温度差值后，通过查询数据库，即可获得与第一温度差值对应的第一调温功率，以及与第二温度差值对应的第二调温功率。
或者，温度差值与调温功率的对应关系，是以控制算法的形式存在的，在控制算法中，温度差值为输入量，调温功率为输出量。这样，在获得第一温度差值和第二温度差值后，将第一温度差值输入至控制算法中，可获得控制算法输出的与第一温度差值对应的第一调温功率，将第二温度差值输入至控制算法中，可获得控制算法输出的与第二温度差值对应的第二调温功率。
这里的控制算法可以是PID控制算法、LQR控制算法或其他具有偏差消除功能的控制算法。
前述调整第一房间的第一空调以及第二房间的第二空调的调温功率，包括：调整第一空调的第一调温功率，维持第二空调的第二调温功率不变；或者，调整第二空调的第二调温功率，位置第一空调的第一调温功率不变；或者，同时调整第一空调的第一调温功率以及第二空调的第二调温功率。
如下为调整第一空调的第一调温功率和/或第二空调的第二调温功率的调整条件：在对第一房间和第二房间同时升温的情况下，如果第三温度差值大于设定温度差值，则需降低第一调温功率和/或提高第二调温功率；如果第三温度差值小于设定温度差值，则需要提高第一调温功率和/或降低第二调温功率；
在对第一房间和第二房间同时降温的情况下，如果第三温度差值大于设定温度差值，则需降低第一调温功率和/或提高第二调温功率；如果第三温度差值小于设定温度差值，则需提高第一调温功率和/或降低第二调温功率。
进一步地，根据第一温度差值调整第一调温功率以及第二调温功率，包括：对第四温度差值进行微分处理，获得微分结果；在需提高第一调温功率的情况下，根据第一调温功率与微分结果的绝对值之和，确定调整后的第一调温功率；在需降低第一调温功率的情况下，根据第一调温功率与微分结果的绝对值之差，确定调整后的第一调温功率；在需提高第二调温功率的情况下，根据第二调温功率与微分结果的 绝对值之和，确定调整后的第二调温功率；在需降低第二调温功率的情况下，根据第二调温功率与微分结果的绝对值之差，确定调整后的第二调温功率。
例如，可将第一调温功率与微分结果的绝对值直接相加的和确定为调温后的第一调温功率；或者，将第一调温功率与微分结果的绝对值加权相加的和确定为调整后的第一调温功率。将第一调温功率与微分结果的绝对值直接相减的差确定为调温后的第一调温功率；或者，将第一调温功率与微分结果的绝对值加权相减的差确定为调整后的第一调温功率。
将第二调温功率与微分结果的绝对值直接相加的和确定为调温后的第二调温功率；或者，将第二调温功率与微分结果的绝对值加权相加的和确定为调整后的第二调温功率。
将第二调温功率与微分结果的绝对值直接相减的差确定为调温后的第二调温功率；或者，将第二调温功率与微分结果的绝对值加权相减的差确定为调整后的第二调温功率。
另外，根据设定温度差值与第三温度差值的第四温度差值，调整第一房间的第一空调以及第二房间的第二空调的调温功率，还可包括：根据第一温度差值和/或第二温度差值、第四温度差值调整第一空调以及第二空调的调温功率，其中，第一空调以及第二空调的调温功率均与第一温度差值和/或第二温度差值正相关。
例如，在根据第一温度差值和第四温度差值调整第一空调以及第二空调的调温功率的情况下，可使第一空调以及第二空调的调温功率与第一温度差值正相关。
在根据第二温度差值和第四温度差值调整第一空调以及第二空调的调温功率的情况下，可使第一空调以及第二空调的调温功率与第二温度差值正相关。
在根据第一温度差值和第二温度差值调整第一空调以及第二空调的调温功率的情况下，可先获得第一温度差值的绝对值和第二温度差值的平均温度值，再使第一空调以及第二空调的调温功率与平均温度值正相关。
在上述技术方案中，第一温度差值小于第二温度差值，即，在两个房间同时升温的情况下，第一室内温度高于第二室内温度；在两个房间同时降温的情况下，第一室内温度低于第二室内温度；这种情况下，如果第一温度差值大于第一温度阈值，则表示第一室内温度和第二室内温度与设定温度之间的差值比较大，此时按照独立的控制策略控制第一空调和第二空调，例如以PID为代表的具有消除偏差功能的控制器，均可使第二控制策略对应的平均室温变化速率大于第一控制策略对应的平均室温变化速率，此时可以使第二房间快速升温；在第一温度差值小于或等于第一温度阈值的情况下，表示第一室内温度和第二室内温度与设置温度的差值较小，此时采用一种控制策略(第三控制策略)对第一空调和第二空调进行控制，使第一房间在第一空调的调节作用下的温度变化速率，和第二房间在第二空调的调节作用下的温度变化速率趋近于相同，在这个阶段中，缓解或消除了前一个阶段中室内温度对空调的调温功率滞后，最终使第一室内温度和第二室内温度的温度差值趋近于稳定，进而使得第一房间的和第二房间的热量流动变得均匀，此时对于室内温度高的房间内空调而言，其调温功率(制冷功率或制热功率)一方面维持本房间的温度变化，另一方面抵消流向室内温度低的房间的热量，由于流向室内温度低的房间的热量流量稳定，可以使室内温度高的房间内的空调稳定地调节本房间的室内温度；同样地，对于室内温度低的房间内空调而言，其调温功率一方面维持本房间的温度变化，另一方面抵消来自室内温度高的房 间的热量，由于来自室内温度高的房间的热量流量稳定，可以使室内温度低的房间内的空调稳定地调节本房间的室内温度，这样提高了升温或降温过程中的室内温度的稳定性，有利于提高两个房间的室内温度达到设定温度时的稳定性。
图3是本申请实施例提供的一种用于控制空调的方法的流程示意图。该用于控制空调的方法可由空调的控制器执行，或者，由与空调通信连接的控制面板或遥控器执行，或者，由智能家居系统的服务器执行。本申请实施例以将该用于控制空调的方法控制图1中所示的第一空调和第二空调为例，对该用于控制空调的方法进行示例性说明。
结合图3所示，用于控制空调的方法包括：
S301、在对存在热交换的第一房间和第二房间同时升温或降温的情况下，获得第一房间的第一室内温度、第二房间的第二室内温度，以及第一房间和第二房间的设定温度。
S302、获得设定温度与第一室内温度之间的第一温度差值，以及设定温度与第二室内温度之间的第二温度差值。
其中，第一温度差值小于第二温度差值，第一控制策略对应的平均室温变化速率小于第二控制策略对应的室温变化速率。
S303、在第一温度差值大于第一温度阈值的情况下，根据第一控制策略控制第一房间的第一空调，以及根据第二控制策略控制第二房间的第二空调。
S304、在第一温度差值小于或等于第一温度阈值，且大于第二温度阈值的情况下，根据第三控制策略控制第一房间的第一空调和第二房间的第二空调。
其中，第三控制策略对应的平均室温变化速率小于或等于第一控制策略对应的平均室温变化速率，并且，在第三控制策略的控制下，第一房间的室温变化速率和第二房间的室温变化速率趋近于相同。
S305、在第一温度差值小于或等于第二温度阈值的情况下，根据第四控制策略控制第一空调，以及根据第五控制策略控制第二空调；
其中，第四控制策略对应的平均室温变化速率小于或等于第三控制策略对应的平均室温变化速率，第五控制策略对应的平均室温变化速率大于第四控制策略对应的平均室温变化速率，第一比值与第二比值的比值差值在预设差值范围内，第一比值为第一温度差值与第四控制策略对应的平均室温变化速率的比值，第二比值为第二温度差值与第五控制策略对应的平均室温变化速率的比值。
第一比值可以反映在第一空调的调节作用下，第一房间的第一室内温度达到设定温度所需的时长；第二比值可以反映在第二空调的调节作用下，第二房间的第二室内温度达到设定温度所需的时长；第一比值和第二比值的比值差值在预设差值范围内，可表示第一房间的第一室内温度达到设定温度所需的时长，与第二房间的第二室内温度达到设定温度所需的时长大体相同。
预设差值范围越大，越容易导致第一房间以及第二房间的室内温度在设定温度附近的波动大，尤其是室内温度最先达到设定温度的房间，其室内温度在设定温度附近的波动更大。本申请实施例对预设差值范围不做具体限定，本领域技术人员可根据对室内温度波动的需求，适应性地选择符合要求的预设差值范围。
第一比值和第二比值反映了将室内温度调节至设定温度所需的时长，空调的制冷功率或制热功率有 限，将室内温度调整设定温度的时长不会过短，第一比值和第二比值不可过小，第四控制策略对应的平均室温变化速率在第一空调对第一房间的调温能力范围内，第五控制策略对应的平均室温变化速率在第二空调对第二房间的调温能力范围内。通常情况下，第一空调的调温功率越大，第四控制策略对应的平均室温变化速率的上限值越大；第一空调的调温功率越小，第四控制策略对应的平均室温变化速率的上限值越小；第一房间的体积越大，第四控制策略对应的平均室温变化速率的上限值越小，第一房间的体积越小，第四控制策略对应的平均室温变化速率的上限值越大；第二空调的调温功率越大，第五控制策略对应的平均室温变化速率的上限值越大；第二空调的调温功率越小，第五控制策略对应的平均室温变化速率的上限值越小；第二房间的体积越大，第五控制策略对应的平均室温变化速率的上限值越小，第二房间的体积越小，第五控制策略对应的平均室温变化速率的上限值越大。
具体地，第四控制策略对应的平均室温变化速率或第五控制策略对应的平均室温变化速率为预期速率，还可以是按照现有的独立房间的温度控制方法调节房间内温度时，房间内温度的平均室温变化速率(即，第一比值或第二比值为消除一定的温度差值所需的平均时长)。
可选地，第四控制策略和第五控制策略的确定，包括：将第三控制策略对应的平均室温变化速率确定为第四控制策略对应的平均室温变化速率，进而确定第一比值，根据第一比值和预设差值范围确定第二比值，以及根据第二比值和第二温度差值确定第五控制策略对应的平均室温变化速率。具体地，利用第三控制策略对应的平均室温变化速率为第四控制策略对应的平均室温变化速率进行赋值，利用第一温度差值除以第四控制策略对应的平均室温变化速率，获得第一比值，确定与第一比值的比值差值在预设差值范围内的第二比值，利用第二温度差值除以第二比值，获得第五控制策略对应的平均室温变化速率。
或者，第四控制策略和第五控制策略的确定，可包括：将第三控制策略对应的平均室温变化速率确定为第五控制策略对应的平均室温变化速率，进而确定第二比值，根据第二比值和预设差值范围确定第一比值，以及根据第一比值和第二温度差值确定第四控制策略对应的平均室温变化速率。具体地，利用第三控制策略对应的平均室温变化速率确定为第五控制策略对应的平均室温变化速率进行赋值，利用第二温度差值除以第五控制策略对应的平均室温变化速率，获得第二比值，确定与第二比值的比值差值在预设差值范围内的第一比值，利用第一温度差值除以第一比值，获得第四控制策略对应的平均室温变化速率。
按照上述方式即可确定出第四控制策略对应的平均室温变化速率以及第五控制策略对应的平均室温变化速率。
