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。
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R1第一室内温度T1和第二房间R2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R1和第二房间R2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R1(例如婴幼儿所在房间)和第二房间R2(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R1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R1和第二房间R2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R1的第一室内温度T1和第二房间R2的第二室内温度T2之间的温度差值较大;在第一房间R1和第二房间R2存在热交换之后,第一房间R1和第二房间R2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R1需要降温,第二房间R2需要升温的情况。
在第一房间R1和第二房间R2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R1和第二房间R2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R1和第二房间R2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R1和第二房间R2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。
本申请实施例中提供的用于控制空调的方法,第三调温阶段对应的室温变化速率(第一房间R1的降温速率和第二房间R2的升温速率)小于第二调温阶段对应的室温变化速率,有利于第一房间R1和第一室内温度T1和第二房间R2的第二室内温度T2比较稳定地达到设定温度(第一房间R1和第二房间R2共用的设定温度),第二调温阶段对应的温度变化速率最大,有利于缩短第一室内温度T1和第二室内温度T2达到设定温度所需的时长;第一调温阶段的室温变化速率小于第二阶段室温变化速率,有利于使第一房间R1和第二房间R2维持较高的温度差值,充分利用第一房间R1和第二房间R2的热量流动,降低了能耗。通过设置不同的调温阶段,可以在降低空调总能耗和快速调温之间取平衡。
图2是本申请实施例提供的一种用于控制空调的方法示意图。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***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、对于存在热交换的第一房间和第二房间,在对第一房间降温、对第二房间升温的情况下,获得当前时刻的第一房间的第一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二室内温度的第二温度差值。
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。
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大于设定温度,第二室内温度小于设定温度,需要对第一房间进行降温处理,对第二房间进行升温处理的情景。
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,可用第一室内温度减去设定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。
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,之后利用第一室内温度和第二室内温度进行计算时,均考虑第一室内温度和第二室内温度的符号。
S202、根据第一温度差值以及第二温度差值,在三个调温阶段中确定当前调温阶段。
在执行该步骤之前,首先设置三个调温阶段,三个调温阶段按照温度差值由大到小的顺序依次为第一调温阶段、第二调温阶段和第三调温阶段。
这里的三个调温阶段,包括第一房间对应的三个降温阶段以及第二房间对应的三个升温阶段。并且,第一房间对应的三个降温阶段与第二房间的对应的三个升温阶段不完全相同,以适应第一房间以及第二房间的工况。第一调温阶段对应第一房间的第一降温阶段以及第二房间的第一升温阶段,第二调温阶段对应第一房间的第二降温阶段以及第二房间的第二升温阶段,第三调温阶段对应第一房间的第三降温阶段以及第二房间的第三升温阶段。
具体地,可以将大于第一温度阈值的区间确定为第一房间对应的第一降温阶段,将小于或等于第一温度阈值且大于第二温度阈值的区间确定为第一房间的第二降温阶段,将小于或等于第二温度阈值的区间确定为第一房间的第三降温阶段;将大于第三温度阈值的区间确定为第二房间对应的第一升温阶段,将小于或等于第三温度阈值且大于第四温度阈值的区间确定为第二房间的第二升温阶段,将小于第四温度阈值的区间确定为第二房间的第三升温阶段。这里的第一温度阈值、第二温度阈值、第三温度阈值以及第四温度阈值均可为在空调出厂前设置;也可在空调出厂后由专业人员手动调试。
这样,根据第一温度差值以及第二温度差值,在三个调温阶段中确定当前调温阶段,可包括:在第一温度差值大于第一温度阈值,且第二温度差值大于第三温度阈值的情况下,将第一调温阶段确定为当前调温阶段;在第一温度差值小于或等于第一温度阈值,大于第二温度阈值,且第二温度差值小于或等于第三温度阈值,大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;在第一温度差值小于或等于第二温度阈值,且第二温度差值小于或等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。
当然,在当前调温阶段为第一调温阶段的情况下,对第二房间而言,该情况为第一降温阶段,对第二房间而言,该情况为第一升温阶段;在当调温阶段为第二调温阶段或第三调温阶段的情况下,当前调温阶段对第一房间和第二房间的具体含义类似,这里不再一一赘述。
在将第一调温阶段确定为当前调温阶段之后,第一房间的第一温度差值持续减小,第二房间的第二温度差值持续减小,将会出现第一温度差值不大于第一温度阈值,且第二温度差值大于第三温度阈值的情况,或者,将会出现第一温度差值大于第一温度阈值,且,第二温度差值不大于第三温度阈值的情况,此时,仍将第一调温阶段确定为当前调温阶段,直至第一温度差值大于第二温度阈值且小于或等于第一温度阈值,第二温度差值大于第四温度阈值且小于或等于第三温度阈值,再将第二调温阶段确定为当前调温阶段。
在将第二调温阶段确定为当前调温阶段之后,第一房间的第一温度差值持续减小,第二房间的第二温度差值持续减小,将会出现第一温度差值小于或等于第二温度阈值,且第二温度差值大于第四温度阈值的情况,或者,将会出现第一温度差值大于第二温度阈值,且第二温度差值小于或等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,直至第一温度差值小于或等于第二温度阈值,且第二温度差值小于或等于第四温度阈值,再将第三调温阶段确定为当前调温阶段。
通过上述技术方案即可确定出当前温度调温阶段。
S203、根据调温阶段与室温变化速率的对应关系,确定与当前调温阶段对应的第一房间的当前降温速率以及第二房间的当前升温速率。
调温阶段与室温变化速率的对应关系,也是在执行本方法之前设置的。并且,对于第一房间而言,调温阶段与室温变化速率的对应关系,指的是降温阶段与室温下降速率的对应关系;对于第二房间而言,调温阶段与室温变化速率的对应关系,指的是升温阶段与室温上升速率的对应关系。
第二调温阶段对应的室温变化速率大于第一调温阶段对应的室温变化速率,第二调温阶段对应的室温变化速率大于第三调温阶段对应的室温变化速率。在第一房间中,第二降温阶段对应的室温下降速率大于第一降温阶段对应的室温下降速率,第二降温阶段对应的室温下降速率大于第三降温阶段对应的室温下降速率;在第二房间中,第二升温阶段对应的室温上升速率大于第一升温阶段对应的室温上升速率,第二升温阶段对应的室温上升速率大于第三升温阶段对应的室温上升速率。
调温阶段与室温变化速率的对应关系,可以是调温阶段与固定室温变化速率的对应关系,也可以是调温阶段与平均室温变化速率的对应关系。
例如,第一调温阶段对应第一房间的第一降温速率以及第二房间的第二升温速率,第二调温阶段应对第一房间的第二降温速率以及第二房间的第二升温速率,该第一降温速率、第二降温速率、第一升温速率以及第二升温速率均可为固定室温变化速率;第三调温阶段对应第一房间的第三降温速率以及第二房间的第三升温速率,该第三降温速率以及第三升温速率可为平均室温变化速率。
通过上述方式,即可获得第一空调的当前降温速率以及第二空调的当前升温速率。
S204、根据当前降温速率控制第一房间的第一空调,以及根据当前升温速率控制第二房间的第二空调。
第一房间的降温速率与第一空调的制冷功率具有对应关系,第二房间的升温速率与第二空调的制热功率具有对应关系。在获得当前降温速率后,即可获得与当前降温速率对应的当前制冷功率,根据该制冷功率控制第一空调,例如,第一空调的压缩机运行频率越大,第一空调的制冷功率越大,第一空调的室内风机转速越高,第一空调的制冷功率越大;在获得当前升温速率后,即可获得与当前升温速率对应的当前制热功率,根据该制热功率控制第二空调,例如,第二空调的压缩机的运行频率越大,第二空调的制热功率越大,第二空调的室内风机转速越高,第二空调制热功率越大。
在当前调温阶段为第三调温阶段的情况下,可以按照现有技术中控制方法(例如PID控制方法)对第一空调和第二空调进行控制,此时第一温度差值和第二温度差值均较小,第一室内温度与第二室内温度之间的差值也比较小,两个房间的热量流动对两个房间的温度影响较小,采用现有控制方法也不会造成过大的超调量,也比较容易地使第一室内温度和第二室内温度稳定在设定温度。
将第一空调对第一房间的降温过程,以及第二空调对第二房间的升温过程均划分为三个调温阶段,第一调温阶段对应的温度差值(第一温度差值和第二温度差值)最大,第三调温阶段对应的温度差值最小,对于第一房间而言,三个调温阶段为三个降温阶段,对于第二房间,三个调温阶段为三个降温阶段;在第一调温阶段的室温变化速率小于第二调温阶段对应的室温变化速率,即为第一调温阶段第一房间的降温速率小于第二调温阶段第一房间的降温速率,第一调温阶段第二房间的升温速率小于第二调温阶段第二房间的升温速率,这样,可以在第一阶段使第一房间和第二房间之间维持较高的温度差,有利于第一房间的热量自由流向第二房间,这样的热量流动有利于同时降低第一房间的温度和提高第二房间的温度,降低了第一空调和第二空调的总能耗;第三调温阶段的室温变化速率小于第二调温阶段的室温变化速率,有利于第一房间和第二房间比较稳定地达到设定温度;在同时对第一房间降温和对第二房间升温的过程中,有效利用了两个房间的热量流动,降低了 第一空调和第二空调的总能耗。
图3是本申请实施例提供的一种第一室内温度和第二室内温度以及二者之间的温度差值的变化示意图。
在图3中,横轴为时间t轴,纵轴为温度T轴;曲线T1为第一室内温度变化曲线,曲线T11为第一室内温度在第一调温阶段的变化曲线,曲线T12为第一室内温度在第二调温阶段的变化曲线,曲线T13为第一室内温度在第三调温阶段对应的变化曲线;曲线T2为第二室内温度示意图,曲线T21为第二室内温度在第一调温阶段的变化曲线,曲线T22为第二室内温度在第二调温阶段的变化曲线,曲线T23为第二室内温度在第三调温阶段对应的变化曲线;T0为设定温度;曲线△T为第一室内温度T1和第二室内温度T2的温度差值的变化曲线,曲线△T1第一室内温度T11和第二室内温度T21的温度差值在第一调温阶段的变化曲线,曲线△T2为第一室内温度T12和第二室内温度T22的温度差值在第二调温阶段的变化曲线,曲线△T3为第一室内温度T13和第二室内温度T23的温度差值在第三调温阶段的变化曲线。这样,图中曲线△T对时间积分值与第一房间和第二房间的热量流动总量对应。在图3中可以看到,曲线△T1对时间的积分值(曲线△T1与时间t轴围成的面积)较大,这样有利于充分利用第一房间和第二房间之间的流动,以在对第一房间降温和对第二房间升温的过程中,降低第一空调和第二空调的总能耗。
在前述实施中,对第一温度阈值、第二温度阈值、第三温度阈值以及第四温度阈值进行了解释,还可以采用如图4的方式确定第一温度阈值以及第三温度阈值。
结合图4所示,三个调温阶段的确定过程,可包括:
S401、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三温度差值以及设定温度与第二房间的第四室内温度的第四温度差值。
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。
即,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,对三个调温阶段(三个调温阶段包括第一房间的三个降温阶段以及第二房间的三个升温阶段)进行确定。
在确定了三个调温阶段之后,再执行前述实施例中的S201、S202、S203以及S204。
同样地,为了便于说明,这里的第三温度差值以及第四温度差值仍为正值,利用第三室内温度减去设定温度,获得第三温度差值,利用设定温度减去第四室内温度,获得第四温度差值。在实际应用中,第三温度差值与第四温度差值均可带正负号。
S402、获得第三温度差值与设定比值的第一乘积,以及第四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,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,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。
S403、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。
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三温度阈值。
具体地,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,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二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,确定为第三温度阈值。
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三温度阈值;获得第三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;将第二温度阈值与第一阈值差值的和,确定为第一温度阈值。
上述第二温度阈值和第四温度阈值均为已知值。上述第二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,第二温度阈值可越小,第一空调的稳定能力越弱,第二温度阈值需越大;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,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,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。
按照上述方式,即可确定出第一温度阈值与第三温度阈值。
S404、根据第一温度阈值和第二温度阈值将第一房间的降温过程划分为三个调温阶段。
S405、根据第三温度阈值和第四温度阈值将第二房间的升温过程划分为三个调温阶段。
S405与S404不区分先后。
按照上述方案确定的第一温度阈值更加符合第一房间的制冷工况,按照上述方案确定的第三温度阈值更加符合第二房间的制热工况,进而划分出符合第一房间工况和第二房间工况的三个调温阶段。
上述过程为划分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调温阶段。
以下对三个调温阶段对应的室温变化速率进行详细说明:
在第三调温阶段,第一空调和第二空调均可采用现有具有消除偏差功能的控制方法,第一房间的室温下降速率(第三降温速率)以及第二房间的室温上升速率(第三升温速率)均可由对应的控制方法进行控制。
在第二调温阶段,第一房间的室温下降速率(第二降温速率)与第一空调的设定制冷功率对应;第二房间的室温上升速率(第二升温速率)与第二空调的设定制热功率对应。设定制冷功率可以是第一空调的额定制冷功率的5/6、4/5或3/4,设定制热功率可以是第二空调的额定制热功率的5/6、4/5或3/4;设定制冷功率与第一空调的额定制冷功率的比值,可以与设定制热功率与第二空调的额定制热功率的比值相等。
在第一调温阶段,可通过如下方式确定调温阶段与室温变化速率的对应关系:获得第三温度差值至第一温度阈值的温度降低值;根据温度降低值与第二设定时长的商,确定与第一调温阶段对应的第一房间的第一降温速率;获得第四温度差值至第三温度阈值的温度升高值;根据温度升高值与第二设定时长的商,确定与第一调温阶段对应的第二房间的第一升温速率。第二设定时长通常大于前述第一设定时长,第二设定时长可以是第一设定时长的2倍、2.5倍、3倍或更多。
按照上述方式可获得调温阶段与室温变化速率的对应关系,之后可依据第一温度差值以及第二温度差值确定当前调温阶段,并根据当前调温阶段对第一空调和第二空调进行控制。
