除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在描述一些实施例时，可能使用了“耦接”和“连接”及其衍伸的表达。术语“连接” 应做广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或成一体；可以是直接相连，也可以通过中间媒介间接相连。例如，描述一些实施例时可能使用了术语“连接”以表明两个或两个以上部件彼此间有直接物理接触或电接触。又如，描述一些实施例时可能使用了术语“耦接”以表明两个或两个以上部件有直接物理接触或电接触。然而，术语“耦接”或“通信耦合(communicatively coupled)”也可能指两个或两个以上部件彼此间并无直接接触，但仍彼此协作或相互作用。这里所公开的实施例并不必然限制于本文内容。
“A、B和C中的至少一个”与“A、B或C中的至少一个”具有相同含义，均包括以下A、B和C的组合：仅A，仅B，仅C，A和B的组合，A和C的组合，B和C的组合，及A、B和C的组合。
“A和/或B”，包括以下三种组合：仅A，仅B，及A和B的组合。
如本文中所使用，根据上下文，术语“如果”任选地被解释为意思是“当……时”或“在……时”或“响应于确定”或“响应于检测到”。类似地，根据上下文，短语“如果确定……”或“如果检测到[所陈述的条件或事件]”任选地被解释为是指“在确定……时”或“响应于确定……”或“在检测到[所陈述的条件或事件]时”或“响应于检测到[所陈述的条件或事件]”。
本文中“适用于”或“被配置为”的使用意味着开放和包容性的语言，其不排除适用于或被配置为执行额外任务或步骤的设备。
另外，“基于”的使用意味着开放和包容性，因为“基于”一个或多个所述条件或值的过程、步骤、计算或其他动作在实践中可以基于额外条件或超出所述的值。
如本文所使用的那样，“约”、“大致”或“近似”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量系统的局限性)所确定。

目前，虽然空调器的运行模式各不相同，但其总体控制策略基本相同，即，建立温区与运行频率的控制逻辑，以及，建立设定温度与运行频率的关系。空调器的这种控制策略决定其耗电量是随机且不可控制的。随着空调器的不断普及，用户对于空调器使用的关注点也在不断变化。例如，用户会在空调器的当前使用过程中较为关注空调器的耗电量情况，进而使得空调器按照目前的控制策略难以满足自身需求。
相关技术中，为满足用户对节省空调器的耗电量的需求，空调器中设置有节电模式，该节电模式例如依赖于电流限频的方式来进行。然而，采用电流限频的方式来节省电量，用户难以将空调器的耗电量与其他家用电器(例如，热水器)的耗电量进行区分，给用户带来不便。
为此，本公开一些实施例提供一种空调器。该空调器可以在提高空调器的能效的同时，区分空调器的耗电量与其他家用电器的耗电量。
图1为根据一些实施例的一种空调器的结构框图。如图1所示，空调器1包括室内机101和室外机102。
空调器1的室内机101室内换热器15。空调器1的室外机102包括压缩机11、四通阀14和室外换热器17。
空调器1还包括膨胀阀16。膨胀阀16可以设置在空调器1的室内机101或室外机102中。例如，如图1所示，膨胀阀16设置在空调器1的室外机102中。
室内换热器15和室外换热器17通过冷媒管路分别与压缩机11、四通阀14和膨胀阀16连接。依次连接的压缩机11、四通阀14、室内换热器15和室外换热器17形成空调器1的冷媒循环回路10。冷媒在冷媒循环回路10中循环流动，以实现空调器1的冷媒循环。冷媒循环包括一系列过程，例如，不仅涉及冷媒的压缩、冷凝、膨胀和蒸发过程，还涉及通过室内换热器15和室外换热器17分别与空气进行换热、并针对已被调节和热交换的空气循环供应冷媒的过程。
室内换热器15被配置为将室内空气与在室内换热器15中传输的冷媒进行热交换，室外换热器17被配置为将室外空气与在室外换热器17中传输的冷媒进行热交换。
两个换热器(例如，室内换热器15和室外换热器17)中的一个换热器被用作冷凝器，另一个换热器被用作蒸发器。例如，当室内换热器15被用作冷凝器时，室外换热器17被用作蒸发器，使得经由室外换热器17吸热后的冷媒通过室内换热器15将热量散发至室内空气而冷凝，此时，空调器1被用作制热模式的加热器。或者，当室内换热器15被用作蒸发器时，室外换热器17被用作冷凝器，使得经由室外换热器17散热后的冷媒通过室内换热器15吸收室内空气的热量而蒸发，此时，空调器1被用作制冷模式的冷却器。
压缩机11被配置为压缩冷媒，以使压缩后的冷媒进入室外换热器17或室内换热器15。例如，压缩机11使得处于低温低压状态的气相冷媒受压缩形成高温高压的气相冷媒。
压缩机11还被配置为排出高温高压的气相冷媒。高温高压的气相冷媒流入冷凝器(例如，室内换热器15或室外换热器17)。冷凝器将高温高压的气相冷媒冷凝成高压状态的液相冷媒，热量通过冷凝过程释放到周围环境。
膨胀阀16被配置为将高压状态的液相冷媒膨胀为低压状态的气液两相态冷媒。
蒸发器(例如，室内换热器15或室外换热器17)通过利用冷媒的蒸发的潜热与待冷却的材料进行热交换来实现制冷效果。例如，蒸发器从周围环境中吸收热量并将低压状态的气液两相冷媒蒸发形成低温低压的气相冷媒。低温低压状态的气相冷媒返回到压缩机11中。由此，冷媒在整个冷媒循环回路10中的循环流动得以完成，从而实现空调器对室内空间温度的调节。
在空调器1的运行过程中，通过提前设定需求时间内期望的耗电量，建立以目标运行频率(target operation frequency,TOF)作为控制对象的空调器1的控制策略，可以实现对空调器1耗电量的控制。而且，采用控制空调器1的运行频率的控制策略会极大地节省空调器1的电量，从而在天气较热或较冷时，使得空调器1在不同的条件下(例如，办公、微运动、读书或睡眠条件)下产生差异化的制冷或制热效果。
当空调器1以预设模式(例如，制冷模式或制热模式)运行时，为便于用户提前设定需求时间内期望的空调器1的耗电量，可以通过终端设备(例如，手机、平板或电脑)建 立用户与空调器1之间的通信连接。在一些实施例中，用户通过在手机软件上输入期望的空调器1的耗电量，例如输入预设电量(preset electric quantity，PQ)，并基于手机与空调器1之间的通信，将所输入的预设电量传输至空调器1。需要说明的是，用户输入的期望的耗电量包括但不限于预设电量PQ。
以下以用户向空调器1输入的期望的耗电量为预设电量PQ为例进行说明。
如图1所示，空调器1还包括接收器12。接收器12被配置为接收用户输入的预设电量PQ。如此，用户通过终端设备与空调器1的接收器12连接，以将用户输入的预设电量传输至接收器12。
接收器12可以包括射频识别(radio frequency identification,RFID)接收器、近场通信(near filed communication，NFC)接收器、红外接收器等。
空调器1还包括控制器13。控制器13与接收器12连接。接收器12还被配置为将接收到的预设电量PQ传输至控制器13。
控制器13包括处理器。处理器可以包括中央处理器(central processing unit,CPU)、微处理器(microprocessor)、专用集成电路(application specific integrated circuit,ASIC)、芯片等，并且可以被配置为当处理器执行存储在耦合到控制器13的非暂时性计算机可读介质中的程序时，执行相应的操作。非暂时性计算机可读存储介质可以包括磁存储设备(例如，硬盘、软盘、或磁带)、智能卡、或闪存设备(例如，可擦除可编程只读存储器(erasable programmable read-only memory,EPROM)、卡、棒、或键盘驱动器)。
图2为根据一些实施例的一种空调器的电量控制方法的流程图。如图1和图2所示，控制器13被配置为获取预设电量PQ；根据预设电量PQ确定第一电量Q1和第二电量Q2，第一电量Q1和第二电量Q2之和小于或者等于预设电量PQ。如此，基于控制器13与接收器12之间的连接，可以实现控制器13对设定电量PQ的划分，从而保证空调器1的制热或者制冷效果。
在一些实施例中，第一电量Q1和第二电量Q2之和等于预设电量PQ。需要说明的是，本公开实施例对第一电量Q1和第二电量Q2的划分标准不做限定，例如，按电量的占比进行划分。而且，在按电量的占比进行划分的情况下，第一电量Q1与第二电量Q2的划分比例可以根据实际需要进行设置，例如，第一电量Q1与第二电量Q2的划分比例为3:7。
例如，可以根据室内环境温度和空调器1的设定温度之间的差异划分第一电量Q1与第二电量Q2的比例。前述差异较大时所对应的第一电量Q1的占比(Q1/(Q1+Q2)＝Q1/PQ)大于前述差异较小时所对应的第一电量Q1的占比。一般情况下，第一电量Q1与第二电量Q2的划分比例小于5:5。但并不绝限于此，在一些实施例中，第一电量Q1与第二电量Q2的划分比例也可以大于5:5。
控制器13还与压缩机11连接。控制器13还被配置为根据第一电量Q1向空调器1供电，控制压缩机11按照空调器1的预设模式运行至第一电量Q1耗尽，并确定压缩机11在第一电量Q1耗尽时对应的第一运行频率OF1。在确定第一运行频率OF1之后，控制器13还被配置为根据第二电量Q2向空调器1供电，并根据第一运行频率OF1确定压缩机11的目标运行频率TOF；根据目标运行频率TOF控制压缩机11运行，直至第二电量Q2耗尽。
如此，本公开一些实施例提供的空调器1通过控制器13获取预设电量PQ，并根据预设电量PQ确定第一电量Q1和第二电量Q2，使得空调器1以第一电量Q1和第二电量Q2 为目标输出预设制冷模式下的冷量或者预设制热模式下的热量，从而实现对空调器1的预设电量PQ的调控而且，通过对空调器1的预设电量PQ进行调控，并按照预设电量PQ控制空调器1的运行频率，用户可以指定空调器的耗电量，从而区分空调器的耗电量与其他家用电器的耗电量。这样，不仅可以消除用户的用电顾虑，还可以在给用户带来便利的同时，提高空调器1的能效。
图3为根据一些实施例的一种压缩机的运行频率与运行时间的关系图。在一些实施例中，如图3所示，当第一电量Q1和第二电量Q2之和等于预设电量PQ时，控制器13将预设电量PQ按占比划分为第一电量Q1和第二电量Q2，第一电量Q1为预设电量PQ的30％，第二电量Q2为预设电量PQ的70％。
首先，控制器13根据第一电量Q1(即，预设电量PQ的30％)向空调器1供电。在控制器13根据第一电量Q1向空调器1供电的过程中，空调器1的压缩机11按照预设制冷模块运行T1时间，此时，压缩机11的运行频率较高，空调器1的制冷效果较为明显。在使用第一电量Q1向空调器1供电时，首先需要维持压缩机11的开机运行，而为了满足压缩机11的开机运行需求，压缩机11的运行频率会先后经历第一平台①和第二平台②，并在经历第二平台②后，随即到达第三平台③，将第三平台③处的运行频率称为第一运行频率OF1。此时，压缩机11按照第一运行频率OF1运行一段时间，并在T1时间运行完成时，认为第一电量Q1耗尽。
然后，在第一电量Q1耗尽后，控制器13确定压缩机11的第一运行频率OF1，此时，控制器13根据第二电量Q2(即，预设电量PQ的70％)向空调器1供电。在使用第二电量Q2向空调器1供电时，控制器13确定空调器1的压缩机11的目标运行频率TOF，并根据目标运行频率TOF控制压缩机11运行，直至第二电量Q2耗尽。
图4为根据一些实施例的另一种空调器的电量控制方法的流程图。在一些实施例中，如图4所示，在根据第一运行频率OF1确定压缩机11的目标运行频率TOF的过程中，控制器13例如被配置为确定第一运行频率OF1对应的第一电流值A1，确定根据第二电量Q2供电时的平均电流值As，并比较第一电流值A1和平均电流值As之间的大小。
例如，如图3和图4所示，控制器13根据第一电量Q1向空调器1供电，当第一电量Q1耗尽时，将空调器1在第一运行频率OF1下对应的电流值记为第一电流值A1。控制器13根据第二电量Q2向空调器1供电时，压缩机11运行T2+T3时间，在T2+T3时间段内，根据空调器1的耗电量、需求的耗电时间及压缩机11的运行电压确定空调器1的平均电流值As。在确定第一电流值A1和平均电流值As后，比较第一电流值A1和平均电流值As之间的大小。
在根据第一运行频率OF1确定压缩机11的目标运行频率TOF的过程中，控制器13还被配置为根据比较结果确定压缩机11的目标运行频率TOF，从而控制压缩机11以目标运行频率TOF运行。如此，通过比较第一电流值A1和平均电流值As的大小来控制压缩机11以不同的运行频率运行，从而使得空调器1的能效得以提高。
本公开一些实施例还提供另一种空调器。该空调器1包括如图1所示的室内机101、室外机102、接收器12和控制器13。需要说明的是，本公开实施例中的室内机101和室外机102的结构和功能均相同与上述实施例中的室内机101和室外机102的结构和功能均相同，在此不再赘述。
接收器12被配置为接收用户输入的预设电量PQ。控制器13分别与接收器12和室外 机102的压缩机11连接。
如图4所示，控制器13被配置为获取预设电量PQ；根据预设电量PQ确定第一电量Q1和第二电量Q2，第一电量Q1和第二电量Q2之和小于或者等于预设电量PQ；根据第一电量Q1向空调器1供电，控制压缩机11按照预设模式运行至第一电量Q1耗尽，并确定压缩机11在第一电量Q1耗尽时对应的第一运行频率OF1；根据第二电量Q2向空调器1供电，并根据第一运行频率OF1确定压缩机11的目标运行频率TOF，以控制空调器1的耗电量；以及根据目标运行频率TOF控制压缩机11运行，直至第二电量Q2耗尽。
在根据第二电量Q2向空调器1供电，并根据第一运行频率OF1确定压缩机11的目标运行频率TOF时，控制器13还被配置为确定第一运行频率OF1对应的第一电流值A1，确定根据第二电量Q2向空调器1供电时的平均电流值As，并比较第一电流值A1和平均电流值As之间的大小；以及根据比较结果确定压缩机11的目标运行频率TOF，以控制压缩机11以目标运行频率TOF运行。
如此，空调器1通过控制器13获取预设电量PQ，并根据预设电量PQ确定第一电量Q1和第二电量Q2，使得空调器1以第一电量Q1和第二电量Q2为目标输出预设制冷模式下的冷量或者预设制热模式下的热量，从而实现对空调器1的预设电量PQ的调控而且，通过对空调器1的预设电量PQ进行调控，并按照预设电量PQ控制空调器1的运行频率，用户可以指定空调器的耗电量，从而区分空调器的耗电量与其他家用电器的耗电量。这样，不仅可以消除用户的用电顾虑，还可以在给用户带来便利的同时，提高空调器1的能效。此外，通过比较第一电流值A1和平均电流值As的大小来控制压缩机11以不同的运行频率运行，从而使得空调器1的能效得以提高。
图5为根据一些实施例的又一种空调器的电量控制方法的流程图。在一些实施例中，如图5所示，在根据比较结果确定压缩机11的目标运行频率TOF的过程中，控制器13被配置为判断第一电流值A1是否小于或者等于平均电流值As。
响应于第一电流值A1小于或者等于平均电流值As(即，A1≤As)，控制器13还被配置为确定第一运行频率OF1为压缩机11的目标运行频率TOF，从而控制压缩机11以第一运行频率OF1运行，直至第二电量Q2耗尽。
此时，认为空调器1在第一电量耗尽Q1后，室内环境温度和空调器1的设定温度之间的温差较小，因此，控制器13无需控制空调器1以较高频率运行，仍控制空调器1以第一运行频率OF1运行即可满足用户对温度的需求。
或者，响应于第一电流值A1大于平均电流值As(即，A1＞As)，控制器13还被配置为对第一运行频率OF1进行降频处理，确定压缩机11的目标运行频率TOF。
此时，认为空调器1在第一电量Q1耗尽后，室内环境温度与空调器1的设定温度之间的差值较大，因此，控制器13需要控制空调器1以较高的频率运行。但是，由于第一运行频率OF1(例如，图3中的第三平台③处的运行频率)本身处于比较高的运行频率，同时，为了兼顾用户可以指定空调器1的耗电量，从而区分空调器1的耗电量与其他家用电器的耗电量的需求，可以适当对第一运行频率OF1进行降频处理，并在降频处理过程中，确定目标运行频率TOF，然后控制压缩机11以该目标运行频率TOF运行，直至第二电量Q2耗尽。
图6为根据一些实施例的又一种空调器的电量控制方法的流程图。在一些实施例中，如图6所示，当第一电流值A1大于平均电流值As时，对第一运行频率OF1进行降频处 理，确定压缩机11的目标运行频率TOF的过程中，控制器13被配置为按照预设频率步长n降低第一运行频率OF1，当降低后的第一电流值A1'小于或等于平均电流值As(即，A1'≤As)时，确定当前压缩机11对应的第二运行频率OF2。
此时，响应于空调器1的第一电流值A1大于平均电流值As，控制器13按照预设频率步长n(例如，2Hz/min)降低第一运行频率OF1。由于压缩机11的运行频率与空调器1的电流值相对应，因此在第一运行频率OF1降低后，对应的第一电流值A1随之降低，如此，控制器13通过控制第一运行频率OF1的降低，可以控制第一电流值A1的降低。在此处，为区别于未被降低的第一电流值A1，将降低后的第一电流值标记为A1'。进而，当降低后的第一电流值A1'小于或者等于平均电流值As时，控制器13确定当前压缩机11对应的第二运行频率OF2。
在一些实施例中，为了维持压缩机11运行的稳定性，控制器13按照预设频率步长n降低第一运行频率OF1时，以较小的频率步长降低。这样，可以避免出现压缩机11的运行频率降低过快导致其运行稳定性较低的问题，从而提高压缩机11运行的稳定性。
当第一电流值A1大于平均电流值As时，对第一运行频率OF1进行降频处理，确定目标运行频率TOF的过程中，控制器13还被配置为根据第二运行频率OF2确定第二电流值A2，并控制压缩机11以第二运行频率OF2运行；在压缩机11以第二运行频率OF2运行的过程中，根据室内环境温度Tin与空调器1的设定温度Tboj之间的关系，确定压缩机11的目标运行频率TOF。
此时，在控制器13确定压缩机11对应的第二运行频率OF2后，与第二运行频率OF2对应的电流值随之确定，将空调器1在第二运行频率OF2下对应的电流值记为第二电流值A2。在确定第二电流值A2后，控制压缩机11以第二运行频率OF2运行一段时间。由于第二运行频率OF2对应的第二电流值A2刚好小于平均电流值As，因此控制器13可以根据室内环境温度Tin与设定温度Tboj之间的关系确定压缩机11的目标运行频率TOF。
可以理解的是，当室内环境温度Tin与设定温度Tboj接近时，认为空调器1在进行制冷时，室内的热量刚好被消耗完，或者，认为在空调器1进行制热时，室内的冷量刚好被消耗完。
图7为根据一些实施例的又一种空调器的电量控制方法的流程图。在一些实施例中，如图7所示，在压缩机11以第二运行频率OF2运行，根据室内环境温度Tin与设定温度Tboj之间的关系，确定压缩机11的目标运行频率TOF的过程中，控制器13被配置为在压缩机11以第二运行频率OF2运行的过程中，判断室内环境温度Tin是否达到设定温度Tobj。
响应于室内环境温度Tin未达到设定温度Tobj，控制器13还被配置为确定第二运行频率OF2为压缩机11的目标运行频率TOF，从而控制压缩机11以目标运行频率运行TOF，直至第二电量Q2耗尽。
此时，认为空调器1在进行制冷时，室内冷负荷还未被消除，或者，认为空调器1在进行制热时，室内热负荷还未被消除。需要说明的是，为保持建筑物的热湿环境，在某一时刻需向房间供应的冷量称为冷负荷。相反，为了补偿房间失热量需向房间供应的热量称为热负荷。因此，空调器1通过控制器13确定第二运行频率OF2为目标运行频率TOF，并控制压缩机11以目标运行频率TOF运行，直至第二电量Q2耗尽，也即，控制压缩机11以第二运行频率OF2运行至预设电量PQ耗尽。
或者，响应于室内环境温度Tin达到设定温度Tobj，控制器13还被配置为按照预设频率步长n降低第二运行频率OF2，直至压缩机11的运行频率达到第三运行频率OF3时，确定第三运行频率OF3为压缩机11的目标运行频率TOF，从而控制压缩机11以目标运行频率TOF运行，直至第二电量Q2耗尽。
此时，认为空调器1在进行制冷时，室内冷负荷已经消耗完，无需再对室内进行降温，或者，认为空调器1在进行制热时，室内热负荷已经消耗完，无需再对室内进行升温。因此，为了节省电量，压缩机11的运行频率会继续降低，直至压缩机11的运行频率降低至第三运行频率OF3。第三运行频率OF3为压缩机11的最小运行频率，将空调器1在压缩机11的最小运行频率运行时对应的电流值记为第三电流值A3。当压缩机的运行频率降低至第三运行频率OF3时，控制压缩机11以第三运行频率OF3运行，直至第二电量Q2耗尽，也即，控制压缩机11以第三运行频率OF3运行至预设电量PQ耗尽。
本公开一些实施例还提供一种空调器的电量控制方法，该电量控制方法应用于上述空调器1中，例如应用于上述空调器1的控制器13上。
如图2所示，空调器1的电量控制方法至少包括S1至S5。
S1，获取预设电量PQ。
在一些实施例中，空调器1在运行制冷模式时，为了实现耗电量的定值化，用户可以通过手机软件输入期望的空调器1的消耗电量，例如输入预设电量PQ，在用户输入预设电量PQ后，接收器12接收预设电量PQ，基于接收器12与控制器13之间的通信，控制器13获取预设电量PQ。
S2，根据预设电量PQ确定第一电量Q1和第二电量Q2，第一电量Q1和第二电量Q2之和小于或者等于预设电量PQ。
在一些实施例中，第一电量Q1和第二电量Q2之和等于预设电量PQ。需要说明的是，为了保证空调器1的制热或者制冷效果，将预设定量PQ进行电量划分，例如将预设电量PQ分为第一电量Q1和第二电量Q2。
S3，根据第一电量Q1向空调器1供电，并控制压缩机11按照空调器1的预设模式运行至第一电量Q1耗尽，并确定压缩机11在第一电量Q1耗尽时对应的第一运行频率OF1。
在一些实施例中，如图3所示，当第一电量Q1和第二电量Q2之和等于预设电量PQ时，将预设电量PQ例如按3:7的占比划分为第一电量Q1(即，预设电量PQ的30％)和第二电量Q2(即，预设电量PQ的70％)。首先，根据第一电量Q1向空调器1供电。在根据第一电量Q1向空调器1供电的过程中，空调器1的压缩机11按照预设制冷模块运行T1时间，此时，压缩机11的运行频率较高，空调器1的制冷效果较为明显。在使用第一电量Q1向空调器1供电时，首先需要维持压缩机11的开机运行，而为了满足压缩机11的开机运行需求，压缩机11的开机运行频率会先后经历第一平台①和第二平台②，并在经历第二平台②后，随即到达第三平台③，将第三平台③处的运行频率称为第一运行频率OF1。此时，压缩机11按照第一运行频率OF1运行一段时间，并在T1时间运行完成时，认为第一电量Q1耗尽。然后，在第一电量Q1消耗完后，确定压缩机11的第一运行频率OF1。
S4，根据第二电量Q2向空调器1供电，并根据第一运行频率OF1确定压缩机11的目标运行频率TOF。
在一些实施例中，如图3所示，在第一电量Q1消耗完后，确定压缩机11的第一运行 频率OF1，此时，根据第二电量Q2(例如，预设电量PQ的70％)向空调器1供电。在使用第二电量Q2向空调器1供电时，确定压缩机11的目标运行频率TOF。
S5，根据目标运行频率TOF控制压缩机11运行，直至第二电量Q2耗尽。
如此，根据本公开一些实施例提供的空调器1的电量控制方法，通过获取预设电量PQ，并根据预设电量PQ确定第一电量Q1和第二电量Q2，使得空调器1以第一电量Q1和第二电量Q2为目标输出预设制冷模式下的冷量或者预设制热模式下的热量，从而实现对空调器1的预设电量PQ的调控。而且，通过对空调器1的预设电量PQ进行调控，并按照预设电量PQ控制空调器1的运行频率，用户可以指定空调器的耗电量，从而区分空调器的耗电量与其他家用电器的耗电量。这样，不仅可以消除用户的用电顾虑，还可以在给用户带来便利的同时，提高空调器1的能效。
需要说明的是，本公开一些实施例的空调器1的电量控制方法的具体实现方式与本公开上述任意实施例的空调器1的具体实现方式类似，因此，为了减少冗余，此处不再赘述。
在一些实施例中，如图4所示，S4中根据第二电量Q2向空调器1供电，并根据第一运行频率OF1确定压缩机11的目标运行频率TOF的电量控制方法包括S41至S42。
S41，根据第二电量Q2向空调器1供电，确定第一运行频率OF1对应的第一电流值A1，确定根据第二电量Q2供电时的平均电流值As，并比较第一电流值A1和平均电流值As之间的大小。
S42，根据比较结果确定压缩机11的目标运行频率TOF，从而控制压缩机11以目标运行频率TOF运行。
本公开一些实施例还提供另一种空调器1的电量控制方法。该如图5所示，空调器1的电量控制方法包括上述的S1至S5，S4包括上述的S41至S42。为了减少冗余，本公开实施例中的空调器1的电量控制方法的步骤可参考上述实施例，此处不再赘述。
如此，该空调器1的电量控制方法，通过获取预设电量PQ，并根据预设电量PQ确定第一电量Q1和第二电量Q2，使得空调器1以第一电量Q1和第二电量Q2为目标输出预设制冷模式下的冷量或者预设制热模式下的热量，从而实现对空调器1的预设电量PQ的调控。而且，通过对空调器1的预设电量PQ进行调控，并按照预设电量PQ控制空调器1的运行频率，用户可以指定空调器的耗电量，从而区分空调器的耗电量与其他家用电器的耗电量。这样，不仅可以消除用户的用电顾虑，还可以在给用户带来便利的同时，提高空调器1的能效。此外，通过比较第一电流值A1和平均电流值As的大小来控制压缩机11以不同的运行频率运行，从而使得空调器1的能效得以提高。
在一些实施例中，如图5所示，S42中根据比较结果确定压缩机11的目标运行频率TOF的电量控制方法包括S421至S423。
S421，判断第一电流值A1是否小于或者等于平均电流值As。

S423，响应于第一电流值A1大于平均电流值As，对第一运行频率OF1进行降频处理，确定压缩机11的目标运行频率TOF，从而控制压缩机11以目标运行频率TOF运行，直至第二电量Q2耗尽。
在一些实施例中，如图6所示，S423中对第一运行频率OF1进行降频处理，确定压 缩机11的目标运行频率TOF的电量控制方法包括S4231至S4233。
S4231，按照预设频率步长n降低第一运行频率OF1，当降低后的第一电流值A1'小于或等于平均电流值As时，确定当前压缩机11对应的第二运行频率OF2。
此时，响应于空调器1的第一电流值A1大于平均电流值As，按照预设频率步长n(例如，2Hz/min)降低第一运行频率OF1。由于压缩机11的运行频率与空调器1的电流值之间相对应，因此在第一运行频率OF1降低后，对应的第一电流值A1随之降低，如此，通过控制第一运行频率OF1的降低，可以控制第一电流值A1的降低。进而，当降低后的第一电流值A1'小于或者等于平均电流值As时，确定当前压缩机11对应的第二运行频率OF2。
在一些实施例中，为了维持压缩机11运行的稳定性，按照预设频率步长n降低第一运行频率OF1时，以较小的频率步长降低。这样，可以避免出现压缩机11的运行频率降低过快导致其运行稳定性较低的问题，从而提高压缩机11运行的稳定性。
S4232，根据第二运行频率OF2确定第二电流值A2，并控制压缩机11以第二运行频率OF2运行。
此时，在确定压缩机11对应的第二运行频率OF2后，与第二运行频率OF2对应的电流值随之确定，将空调器1在第二运行频率OF2下对应的电流值记为第二电流值A2。
S4233，在压缩机11以第二运行频率OF2运行的过程中，根据室内环境温度Tin与设定温度Tobj之间的关系，确定压缩机11的目标运行频率TOF。
此时，在确定第二电流值A2后，控制压缩机11以第二运行频率OF2运行一段时间。由于第二运行频率OF2对应的第二电流值A2刚好小于平均电流值As，因此可以根据室内环境温度Tin与设定温度Tboj之间的关系确定压缩机11的目标运行频率TOF。
可以理解的是，当室内环境温度Tin与设定温度Tboj接近时，认为空调器1在进行制冷时，室内的热量刚好被消耗完，或者，认为在空调器1进行制热时，室内的冷量刚好被消耗完。
在一些实施例中，如图7所示，S4233中在压缩机11以第二运行频率OF2运行的过程中，根据室内环境温度Tin与设定温度Tobj之间的关系确定压缩机11的目标运行频率TOF的电量控制方法包括S42331至S42333。
S42331，在压缩机11以第二运行频率OF2运行的过程中，判断室内环境温度Tin是否达到设定温度Tobj。
S42332，响应于室内环境温度Tin未达到设定温度Tobj，确定第二运行频率OF2为压缩机11的目标运行频率TOF，从而控制压缩机11以目标运行频率TOF运行，直至第二电量Q2耗尽。
此时，认为空调器1在进行制冷时，室内冷负荷还未被消除，或者，认为空调器1在进行制热时，室内热负荷还未被消除。因此，通过确定第二运行频率OF2为目标运行频率TOF，并控制压缩机11以目标运行频率TOF运行，直至第二电量Q2耗尽，也即，控制压缩机11以第二运行频率OF2运行至预设电量PQ耗尽。
S42333，响应于室内环境温度Tin达到设定温度Tobj，按照预设频率步长n降低第二运行频率OF2，直至压缩机11的运行频率达到第三运行频率OF3时，确定第三运行频率OF3为压缩机11的目标运行频率TOF，从而控制压缩机11以目标运行频率TOF运行，直至第二电量Q2耗尽。
此时，认为空调器1在进行制冷时，室内冷负荷已经消耗完，无需再对室内进行降温，或者，认为空调器1在进行制热时，室内热负荷已经消耗完，无需再对室内进行升温。因此，为了节省电量，压缩机11的运行频率会继续降低，直至压缩机11的运行频率降低至第三运行频率OF3。第三运行频率OF3为压缩机11的最小运行频率，压缩机11的最小运行频率对应的电流值记为第三电流值A3。当压缩机11的运行频率降低至第三运行频率OF3时，控制压缩机11以第三运行频率OF3运行，直至第二电量Q2耗尽，也即，控制压缩机11以第三运行频率OF3运行至预设电量PQ耗尽。
