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：
对于存在热交换的第一房间和第二房间，第一房间处于降温状态，第二房间处于升温状态，如果温度差值越大，使第一房间中第一空调的制冷功率越大，使第二房间的第二空调的制热功率越大，则容易导致两个房间的热量流量较少，提高了空调能耗。

具体实施方式
为了能够更加详尽地了解本申请实施例的特点与技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。在以下的技术描述中，为方便解释起见，通过多个细节以提供对所披露实施例的充分理解。然而，在没有这些细节的情况下，一个或一个以上实施例仍然可以实施。在其它情况下，为简化附图，熟知的结构和装置可以简化展示。
本申请实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请实施例的实施例。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含。
除非另有说明，术语“多个”表示两个以上。
本申请实施例中，字符“/”表示前后对象是一种“或”的关系。例如，A/B表示：A或B。
术语“和/或”是一种描述对象的关联关系，表示可以存在三种关系。例如，A和/或B，表示：A或B，或，A和B这三种关系。
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RM1和第二房间RM2，第一房间RM1中安装有第一空调K1，第一空调K1可调节第一房间RM1内的第一室内温度T1，第二房间RM2中安装有第二空调K2，第二空调K2可调节第二房间RM2内的第二室内温度T2，第一房间RM1和第二房间RM2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RM1经过通道P流向第二房间RM2，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RM2经过通道P流向第一房间RM1，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RM1和第二房间RM2是否存在热交换。
本申请实施例中提供的用于控制空调的方法，适合应用于第一房间RM1第一室内温度T1和第二房间RM2的第二室内温度T2之间的温度差值较大的场景。例如第一房间RM1和第二房间RM2由不存在热交换的状态切换至存在热交换的状态之前，第一房间RM1(例如婴幼儿所在房间)和第二房间RM2(例如青年所在房间)各自所需的设定温度均不相同，且第一房间RM1和第二房间T2的第一室内温度T1和第二室内温度T2均达到了各自设定温度；这样，在第一房间RM1和第二房间RM2由不存在热交换的状态切换至存在热交换的状态后，第一房间RM1的第一室内温度T1和第二房间RM2的第二室内温度T2之间的温度差值较大；在第一房间RM1和第二房间RM2存在热交换之后，第一房间 RM1和第二房间RM2共用的设定温度需要在各成员最适温度之间取平衡，此时，通常会出现第一房间RM1需要降温，第二房间RM2需要升温的情况。
在第一房间RM1和第二房间RM2存在热交换之后，如果使第一空调K1和第二空调K2均停机，在自然热交换的情况下，使两个房间的温度趋于平衡，显然将会导致耗时过长；如果使第一空调K1和第二空调K2均按照常规的控制方法进行制冷和制热，例如采用比例-积分-微分(Proportion Integral Differential，PID)，则在第一房间RM1和第二房间RM2之间的温度差值较大时，第一空调K1和第二空调K2均快速降低，相当于在第一房间RM1和第二房间RM2之间的热量流量最大时进行了快速降温或升温，最大程度地降低了第一房间RM1和第二房间RM2之间的热量流动对第一室内温度T1的降温影响以及对第二室内温度T2的升温影响，使得能耗较高。
在本申请实施例中，在第一调温阶段使第一房间RM1的第一降温速率较低，第二房间RM2的第一升温速率较低，可以使第一房间RM1和第二房间RM2之间维持较高的温度差值，有利于第一房间RM1和第二房间RM2之间的热量流动，两个房间的热量流动有利于降低第一房间RM1的第一室内温度T1，有利于提高第二房间RM2的第二室内温度T2，这会降低第一空调K1和第二空调K2的总能耗；在第二调温阶段，使第一房间RM1和第二降温速率较高，第二房间RM2的第二升温速率较高，可以使第一房间RM1和第二房间RM2均比较快速地达到设定温度。通过设置两个不同调温阶段，可以平衡空调总能耗和调温速度(两个房间的温度达到设定温度的速度)。
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、在对第一房间降温、对第二房间升温的情况下，获得第一房间的第一室内温度以及第二房间的第二室内温度。
第一房间和第二房间存在热交换，第一室内温度高于第二室内温度，热量可由第一房间流向第二房间。
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，以满足各个用户的舒适度需求。
在第一房间和第二房间共用一个设定温度的情况下，第一室内温度高于设定温度，需要对第一房间进行降温处理；第二室内温度低于设定温度，需要对第二房间进行升温处理。
S202、根据第一室内温度和第二室内温度，在预设调温阶段中确定当前调温阶段。
预设调温阶段是在执行上述步骤之前设置的，预设调温阶段包括第一调温阶段和第二调温阶段，第一调温阶段对应的第一房间的第一降温速率大于第二调节温度对应的第一房间的第二降温速率，第一调温阶段对应第二房间的第一升温速率大于第二调温阶段对应的第二房间的第二降温速率。
在本申请实施例中，为便于说明，降温速率(包含上述第一降温速率、第二降温速率以及后文的第三降温速率)以及升温速率(包含上述第一升温速率、第二升温速率以及后文的第三升温速率)均采 用正数表示；当然，在具体应用过程中，为便于计算，可以使降温速率以及升温速率带有正负号。
降温速率与第一房间的第一空调的制冷功率正相关，第二降温速率对应的第一空调的制冷功率不超过第一空调的额定制冷功率；升温速率与第二空调的制热功率正相关，第二升温速率对应的第二空调的制热功率不超过第二空调的额定制热功率。
具体地，根据第一室内温度和第二室内温度，在预设调温阶段中确定当前调温阶段，包括：在第一室内温度大于或等于第一温度阈值，且第二室内温度小于或等于第二温度阈值的情况下，将第一调温阶段确定为当前调温阶段；在第一室内温度小于第一温度阈值，且第二室内温度大于第二温度阈值的情况下，将第二调温阶段确定为当前调温阶段。
其中，第一温度阈值和第二温度阈值可以是预先设置的，第一温度阈值大于第一房间的设定温度，第二温度阈值小于第二房间的设定温度。在此基础上，本申请实施例提供的方案，适用于第一房间的第一室内温度由大于第一温度阈值逐渐降低至设定温度，且第二房间的第二室内温度由小于第二温度阈值之间提高至设定温度的情况。
当然，第一温度阈值和第二温度阈值还有其他设置方式，在后文中将详细说明。
在第一室内温度大于或等于第一温度阈值，且，第二室内温度小于或等于第二温度阈值的情况下，当前调温阶段为第一调温阶段，随着时间的推移，第一室内温度下降，第二室内温度上升，会出现第一室内温度大于或等于第一温度阈值，且第二室内温度大于第二温度阈值的情况，或者，出现第一室内温度小于第一温度阈值，且第二室内温度小于或等于第二温度阈值的情况，此时仍将第一调温阶段确定为当前调温阶段，直至出现第一室内温度小于第一温度阈值，且第二室内温度大于第二温度阈值的情况，再将第二调温阶段确定为当前调温阶段。
进一步地，预设调温阶段还可包括第三调温阶段，第三调温阶段对应的第一房间的第三降温速率小于第二降温速率，第三调温阶段对应的第二房间的第三升温速率小于第二升温速率，第三调温阶段的确认，可包括：在第一室内温度小于第三温度阈值，且第二室内温度大于第四温度阈值的情况下，将第三调温阶段确定为当前调温阶段；第三温度阈值小于第一温度阈值，第四温度阈值大于第二温度阈值；其中，第三温度阈值和第四温度阈值为已知值，第三温度阈值大于第一房间的设定温度，第四温度阈值小于第二房间的设定温度。
此时第二调温阶段的确认，可包括：在第一室内温度小于第一温度阈值且大于或等于第三温度阈值，且，第二室内温度大于第二温度阈值且小于或等于第四温度阈值的情况下，将第二调温阶段确定为当前调温阶段。
当然，在第二调温阶段中，第一房间的第一室内温度逐渐下降，第二房间的第二室内温度逐渐上升，会出现第一室内温度小于第三温度阈值，但第二室内温度不大于第四温度阈值的情况，或者，会出现第一室内温度不小于第三温度阈值，但第二室内温度大于第四温度阈值的情况，此时仍将第二调温阶段确定为当前调温阶段，直至在第一室内温度小于第三温度阈值且第二室内温度大于第二室内温度大于第四温度阈值的情况下，将第三调温阶段确定为当前调温阶段。
第三升温速率小于第二升温速率，第三降温速率小于第二降温速率，有利于第一房间的第一室内温度稳定地降低至设定温度，第二房间的第二室内温度稳定地降低至设定温度。
在确定当前调温阶段后，即可依据当前调温阶段对应的降温速率控制第一房间的第一空调，依据当前调温阶段对应的升温速率控制第二房间的第二空调。
S203、在当前调温阶段为第一调温阶段的情况下，获得第一房间的第一空调的制冷能效比以及第二房间的第二空调的制热能效比。
能效比用于表示能源转换效率之比，制冷能效比是空调的制冷性能系数，表示空调单位功率下的制冷量；制热能效比是空调的制热性能系数，表示空调单位功率下的制热量。
S204、如果制冷能效比大于制热能效比，则降低第一升温速率，并控制第二房间的第二空调，使第二房间的升温速率为降低后的第一升温速率。
其中，降低第一升温速率，可包括：降低第一升温速率，维持第一降温速率不变；或者，降低第一升温速率，提高第一降温速率；或者，降低第一升温速率，降低第一降温速率，使第一升温速率的降低值大于第一降温速率的降低值。
第二空调的制热效果，以及第一房间和第二房间之间的热量流动，均对第二房间的温度升高起作用。第一升温速率与第二空调的制热功率正相关，降低第一升温速率，那么第二空调的制热功率也会适应性的降低，此时对于第二房间而言，第二空调的制热效果对第二房间的温度升高作用减弱，对应地，第一房间和第二房间之间的热量流动对第二房间的温度升高作用增强，这有利于降低第二房间的第二空调的能耗。并且，第一空调的制冷能效比大于第二空调的制热能效比，降低第二空调的制热功率，还有利于在整体上提高第一空调和第二空调的能效比。
在第一房间和第二房间的体积相同的情况下，即使同时提高第一降温速率，由于第一空调的制冷能效比大于第二空调的制热能效比，在第一降温速率的提高值与第一升温速率的降低值相同的情况下，第二空调所减少的能耗也大于第一空调所增加的能耗，也有利于降低第一空调和第二空调的总能耗。
具体地，控制第二房间的第二空调，使第二房间的升温速率为降低后的第一升温速率，可包括：根据第二房间的体积以及降低后的第一升温速率，确定对应的第二空调的制热功率，根据确定的第二空调的制热功率控制第二空调运行。第一房间的体积越大，则第二空调的制热功率越大，第一升温速率越大，则第二空调的制热功率越大。
S205、如果制冷能效比小于制热能效比，则降低第一降温速率，并控制第一房间的第一空调，使第一房间的降温速率为降低后的第一降温速率。
其中，降低第一降温速率，可包括：降温第一降温速率，维持第一升温速率不变；或者，降低第一降温速率，提高第一升温速率；或者，降低第一降温速率，降低第一升温速率，使第一降温速率的降低值大于第一升温速率的降低值。
第一空调的制冷效果，以及第一房间和第二房间之间的热量流动，均对第一房间的温度降低起作用。第一降温速率与第一空调的制冷功率正相关，降低第一降温速率，那么第一空调的制冷功率也会适应性的降低，此时对于第一房间而言，第一空调的制冷效果对第二房间的温度降低作用减弱，对应地，第一房间和第二房间之间的热量流动对第一房间的温度降低作用增强，这有利于降低第一房间的第一空调的能耗。并且，第一空调的制冷能效比小于第二空调的制热能效比，降低第一空调的制冷功率，还有利于在整体上提高第一空调和第二空调的能效比。
在第一房间和第二房间的体积相同的情况下，即使同时提高第一升温速率，由于第一空调的制冷能效比小于第二空调的制热能效比，在第一升温速率的提高值与第一降温速率的降低值相同的情况下，第一空调所减小的能耗也大于第二空调所增加的能耗，也有利于降低第一空调和第二空调的总能耗。
具体地，控制第一房间的第一空调，使第一房间的降温速率为降低后的第一降温速率，可包括：根据第一房间的体积以及降低后的第一降温功率，确定对应的第一空调的制冷功率，根据确定的第一空调的制冷功率控制第一空调运行。
在制冷能效比等于制热能效比的情况下，可控制第一空调和第二空调，使第一房间的降温速率为第一调温阶段对应的第一降温速率，使第二房间的升温速率为第一调温阶段对应的第一升温速率。
第一调温阶段对应的第一房间的第一降温速率小于第二调温阶段对应的第一房间的第二降温速率，第二调温阶段对应的第二房间的第一升温速率小于第二调温阶段对应的第二房间的第二升温速率；这样，在第二调温阶段中，第一房间的第一室内温度和第二房间的第二室内温度之间的温度差值迅速减小，有利于以较快的速度将第一室内温度和第二室内温度调整至设定温度；在第一调温阶段中，第一房间的第一室内温度和第二房间的第二室内温度之间维持较大的温度差值，有利于第一房间的热量流向第二房间，利用被动的热量流动为第一房间降温以及为第二房间升温，并且，在第一调温阶段中，如果制冷能效比大于制热能效比，则降低第一升温速率，使两个房间的热量流动对第二房间的升温影响更大，以降低第二房间的第二空调的能耗；如果制冷能效比小于制热能效比，则降低第一降温速率，使两个房间的热量流动对第一房间的降温影响更大，以降低第一房间的第一空调的能耗，最终在第一房间的降温过程和第二房间的升温过程中，降低了第一空调和第二空调的总能耗。
预设调温阶段可包括第一调温阶段和第二调温阶段，在当前调温阶段为第二调温阶段的情况下，控制第一房间的第一空调和第二房间的第二空调，使第一房间的降温速率为第二降温速率，第二房间的升温速率为第二升温速率。
在上述情况下，在第一调温阶段中，可以使第一房间实现等速率降温，使第二房间实现等速率升温；在第二调温阶段中，可以在第一房间和第二房间进行不等速率调温，例如利用现有的温度控制器(例如PID控制器)对第一室内温度和第二室内温度进行控制，使第一室内温度和第二室内温度均趋近于设定温度。
预设调温阶段还可包括第三调温阶段，在当前调温阶段为第三调温接的情况下，控制第一房间的第一空调和第二房间的第二空调，使第一房间的降温速率为第三降温速率，第二房间的升温速率为第三升温速率。
在上述情况下，在第一调温阶段中，可以使第一房间实现等速率降温，使第二房间实现等速率升温；在第二调温阶段中，可以使第一房间实现等速率降温，使第二房间实现等速率升温；在第三调温阶段中，可以在第一房间和第二房间进行不等速率调温，例如利用现有的温度控制器(例如PID控制器)对第一室内温度和第二室内温度进行控制，使第一室内温度和第二室内温度均趋近于设定温度。这样，在利用现有的温度控制器将第一室内温度和第二室内温度调节至设定温度的过程中，第一室内温度的降低值较小，第二室内温度的升高值较小，更有利于降低二者达到设定温度时的超调量，有利于使第一室内温度和第二室内温度均稳定地达到设定温度。
本申请实施例中提供的用于控制空调的方法，比较适于第一房间的初始温度与设定温度的差值较大，且第二房间的初始温度与设定温度的差值较大的情况；并且，如果制冷能效比大于制热能效比，则在第一房间的初始温度与设定温度的差值大于第二房间的初始温度与设定温度的差值的情况下，本方法可取得较佳的效果，如果制冷能效比小于制热能效比，则在第一房间的初始温度与设定温度的差值小于第二房间的初始温度与设定温度的差值的情况下，本方法可取得较佳的效果。
图3是本申请实施例提供的一种用于确定预设调温阶段的过程的示意图。结合图3所示，预设调温阶段的确定，包括：
S301、在首次执行本方法时，获得第一房间的第三室内温度与设定温度的第一温度差值，以及设定温度与第二房间的第四室内温度的第二温度差值。
在首次执行本方法时，依据当时第一房间的第三室内温度、第二房间的第四设定温度以及设定温度，对预设调温阶段进行确定。
在第一房间和第二房间由不存在热交换状态切换至存在热交换状态后，属于首次执行本方法的情况；或者，在设定温度改变后，属于首次执行本方法的情况。
这里的设定温度指的是第一房间和第二房间共用的设定温度。
在本申请实施例中，为便于说明，这里的第一温度差值以及第二温度差值为正值，利用第三室内温度减去设定温度，获得第一温度差值，利用设定温度减去第四室内温度，获得第二温度差值。在实际应用中，第一温度差值与第二温度差值均可带正负号。
S302、获得第一温度差值与设定比值的第一乘积，以及第二温度差值与设定比值的第二乘积。
这里的设定比值可大于或等于1/2，例如，设定比值可为1/2、2/3、3/4或4/5。
如果设定比值过大，则会导致第一室内温度和第二室内温度达到设定温度所需时长过长；如果设定比值过小，则会导致第一空调和第二空调的能耗增加。本领域技术人员可据此确定符合实际需要的设定比值，这里不再一一赘述。
S303、根据第一乘积与第二乘积的大小关系，确定第一温度阈值和第二温度阈值。
如果第一乘积小于第二乘积，则可将第一乘积确定为第一温度阈值；如果第一乘积大于或等于第二乘积，则可将第二乘积确定为第二温度阈值。
具体地，根据第一乘积与第二乘积的大小关系，确定第一温度阈值和第二温度阈值，可包括：在第一乘积小于第二乘积的情况下，将第一乘积与设定温度的和，确定为第一温度阈值；根据第一温度阈值确定第二温度阈值，以在相同时长内，使第一房间在第一空调控制下由第一温度阈值降低至设定温度，第二房间在第二空调的控制下由第二温度阈值升高至设定温度。
或者，在第二乘积小于第一乘积的情况下，将设定温度与第二乘积的差，确定为第二温度阈值；根据第二温度阈值确定第一温度阈值，以在相同时长内，使第一房间在第一空调控制下由第一温度阈值降低至设定温度，第二房间在第二空调的控制下由第二温度阈值升高至设定温度。
在第一房间和第二房间不存在热交换的情况下，在相同时长内，第一房间在第一空调控制下由第一温度阈值降低至设定温度，第二房间在第二空调的控制下由第二温度阈值升高至设定温度。第一温度阈值与第一房间的体积负相关，第一温度阈值与第一空调的制冷功率正相关；第二温度阈值与第一房间 的体积正相关，第二温度阈值与第二空调的制热功率负相关。在上述相同时长确定的情况下，第一温度阈值和第二温度阈值可通过试验的方式获得。
上述相同时长的时长越长，则第一房间快速降温的时长越长，第一房间由初始温度达到设定温度所需时长越短，同样，第二房间由初始温度达到设定温度所需时长越短；上述相同时长越短，则第一房间快速降温的时长越短，第一房间由初始温度达到设定温度所需的时长越长，同样，第二房间由初始温度达到设定温度所需时长越长。本领域技术人员可依据对第一房间由初始温度达到设定温度的预期时长，以及对第二房间由初始温度达到设定温度的预期时长，适应性调整上述相同时长，这里不做具体限定。
上述确定第一温度阈值和第二温度阈值的方案，适用于预设调温阶段包括第一调温阶段和第二调温阶段两个调温阶段情况。
在预设调温阶段还包括第三调温阶段的情况下，根据第一乘积和第二乘积的大小关系，确定第一温度阈值和第二温度阈值，包括：在第一乘积小于第二乘积的情况下，将第一乘积确定为第一温度阈值；获得第一温度阈值与第三温度阈值之间的第一阈值差值；获得与第一阈值差值对应的第二阈值差值；将第四温度阈值和第二阈值差值的和，确定为第二温度阈值。
或者，根据第一乘积和第二乘积的大小关系，确定第一温度阈值和第三温度阈值，可包括：在第一乘积大于或等于第二乘积的情况下，将第二乘积确定为第二温度阈值；获得第二温度阈值与第四温度阈值的第二阈值差值；获得与第二阈值差值对应的第一阈值差值；将第三温度阈值与第一阈值差值的和，确定为第一温度阈值。
上述第三温度阈值和第四温度阈值均为已知值。上述第三温度阈值与第一空调对第一房间进行温度调节时的稳定能力相关，第一空调的稳定能力越强，第三温度阈值可越小，第一空调的稳定能力越弱，第三温度阈值需越大；上述第四温度阈值与第二空调对第二房间进行温度调节时的稳定能力相关，第二空调的稳定能力越强，第四温度阈值可越小，第二空调的稳定能力越弱，第四温度阈值需越大。
第一空调对第一房间进行温度调节时的稳定能力，可用第一室内温度首次达到设定温度，至第一室内温度与设定温度的差值稳定在死区范围内所需的时长进行表示，该时长越长，第一空调的稳定能力越弱，该时长越短，第一空调的稳定能力越强。
第二空调对第二房间进行温度调节时的稳定能力，可用第二室内温度首次达到设定温度，至第二室内温度与设定温度的差值稳定在死区范围内所需的时长进行表示，该时长越长，第二空调的稳定能力越弱，该时长越短，第二空调的稳定能力越强。
上述第一阈值差值与第二阈值差值的对应关系，可包括：在第一房间和第二房间不存在热交换的情况下，控制第一空调按照设定制冷功率运行第一设定时长，将第一房间的下降温度确定为第一阈值差值；控制第二空调按照设定制热功率运行第一设定时长，将第二房间的上升温度确定为第二温度阈值。
上述第一设定时长的时长越长，则第一房间快速降温的时长越长，第一房间由初始温度达到设定温度所需时长越短，同样，第二房间由初始温度达到设定温度所需时长越短；上述第一设定时长越短，则第一房间快速降温的时长越短，第一房间由初始温度达到设定温度所需的时长越长，同样，第二房间由初始温度达到设定温度所需时长越长。本领域技术人员可依据对第一房间由初始温度达到设定温度的 预期时长，以及对第二房间由初始温度达到设定温度的预期时长，适应性调整上述第一设定时长，这里不做具体限定。
这里的设定制冷功率可以是第一空调的额定制冷功率，设定制热功率可以是第二空调的额定制热功率；或者，设定制冷功率与第一空调的额定制冷功率的比值，与设定制热功率与第二空调的额定制热功率的比值相同。该比值可以是5/6、4/5、3/4等。
在预设调温阶段包括三个调温阶段的情况下，按照上述方式即可确定出第一温度阈值与第二温度阈值。
S304、根据第一温度阈值将第一房间的降温过程划分为第一降温阶段和第二降温阶段。
将大于或等于第一温度阈值的温度区间确定为第一降温阶段，将小于第一温度阈值且大于设定温度的温度区间确定为第二降温阶段。
在预设调温阶段还包括第三调温阶段的情况下，可根据第一温度阈值和第三温度阈值将第一房间的降温过程划分为第一降温阶段、第二降温阶段和第三降温阶段。
将大于或等于第一温度阈值的温度区间确定为第一降温阶段，将小于第一温度阈值且大于或等于第三温度阈值的温度区间确定为第二降温阶段，将小于第三温度阈值且大于设定温度的温度区间确定为第三降温阶段。
S305、根据第二温度阈值将第二房间的升温过程划分为第一升温阶段和第二升温阶段。
将小于或等于第二温度阈值的温度区间确定为第一升温阶段，将大于第二温度阈值且小于设定温度的温度区间确定为第二升温阶段。
在预设调温阶段还包括第三调温阶段的情况下，可根据第二温度阈值和第四温度阈值将第二房间的升温过程划分为第一升温阶段、第二升温阶段和第三升温阶段。
将小于或等于第二温度阈值的温度区间确定为第一升温阶段，将大于第二温度阈值且小于或等于第四温度阈值的温度区间确定为第二升温阶段，将大于第四温度阈值且小于设定温度的温度区间确定为第三升温阶段。
S304和S305不区分先后。
上述过程为划分两个或三个调温阶段的过程，按照划分规则，第一房间的温度达到第一温度阈值和第二房间的温度达到第三温度阈值的时刻相同；第一房间的温度达到第二温度阈值和第二房间的温度达到第四温度阈值的时刻相同。在具体应用中，仍按照前述的根据第一温度差值和第二温度差值来确定具体的调温阶段。
以下对各个调温阶段对应的室温变化速率进行详细说明：
