[空调的基本运行原理]
空调的制冷循环包括压缩机、冷凝器、膨胀阀和蒸发器。制冷循环包括一系列过程，涉及压缩、冷凝、膨胀和蒸发，并向已被调节和热交换的空气供应制冷剂。
压缩机压缩形成高温高压状态的制冷剂气体并排出压缩后的制冷剂气 体。所排出的制冷剂气体流入冷凝器。冷凝器将压缩后的制冷剂冷凝成液相，并且热量通过冷凝过程释放到周围环境。
膨胀阀使在冷凝器中冷凝的高温高压状态的液相制冷剂膨胀为低温低压的液相制冷剂。
蒸发器蒸发在膨胀阀中膨胀的制冷剂，并使处于低温低压状态的制冷剂气体返回到压缩机。
蒸发器可以通过利用制冷剂蒸发的潜热与待冷却的材料进行热交换来实现制冷效果。在整个循环中，空调可以调节室内空间的温度。
空调室外机是指包括制冷循环的压缩机的部分以及包括室外热交换器，空调室内机包括室内热交换器，并且膨胀阀可以提供在空调室内机或室外机中。
室内热交换器和室外热交换器用作冷凝器或蒸发器。当室内热交换器用作冷凝器时，空调用作制热模式的加热器，当室内热交换器用作蒸发器时，空调用作制冷模式的冷却器。
空调器
空调器包括至少一个室外机、至少两个室内机、至少一个线控器、网关设备、云平台和APP侧。
参见图1，其示出了一个室外机、两个室内机(1#室内机和2#室内机)、一个线控器、网关设备、云平台和APP侧。
各室外机与各室内机通过通信总线通信连接。
各室外机和室内机均具有各自的地址号。
一个室外机和对应一个室内机形成空调设备，执行调节空气的功能。
在本申请中，空调设备的状态(即，室内机的状态)可以包括开关机、(制冷/制热/除湿)模式、风量以及附加功能，该附加功能可以包括节能、静音、睡眠、健康、自清洁、森林风、辅热、加湿等功能。
线控器用于控制室内机工作。
线控器可以为带有通信模块的无线线控器(例如WiFi线控器)，也可以为不带有通信模块的有线线控器。
在本申请中，设置至少一个线控器，且每个线控器分别具有线控器标识位。
例如，具有两个线控器：1#线控器和2#线控器，1#线控器具有线控器标识位flag1；2#线控器具有线控器标识位flag2。
每个线控器下能够控制至少两个室内机。
例如，1#线控器下控制两个室内机：11#室内机和12#室内机；2#线控器下控制三个室内机：21#室内机、22#室内机和23#室内机。
例如，11#室内机具有如下状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)，记为11#状态集。
12#室内机具有如下状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、自清洁)，记为12#状态集。
此时，在1#线控器上应显示开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音)。
21#室内机具有如下状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠、健康)，记为21#状态集。
22#室内机具有如下状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠、自清洁、森林风)，记为22#状态集。

网关设备具有通信模块，不限于WiFi/NB-IOT等方式的通信，用于上报空调设备的状态至云平台。
该网关设备可以是配置在室外机上的NB-IOT适配器，该NB-IOT适配器包括主控芯片和连接于主控芯片的通讯芯片。
主控芯片用于获取空调系统中内外机组的运行信息，并将状态变化传输至通讯芯片。
通讯芯片用于接收该状态变化，并向云平台反馈当前空调系统中内外机组的状态。
该网关设备还可以为WiFi网关，其可以独立于空调系统、连接于通信总线上，能够向云平台上报如上所述的空调系统相关的信息。
云平台通过网关设备与室外机及室内机实现交互。
为了在同一个线控器控制多个室内机时，能够通过APP侧实现对空调设备的控制，本申请中云平台能够根据所有线控器的线控器标识位及各线控器所连接的所有室内机的状态，计算所有室内机的状态的交集，并与APP侧交互后，在APP侧输出。
云平台能够存储通过网关设备上报的空调设备的状态、室内机的地址号及各线控器的线控器标识位。
室内机的地址号用于接收APP侧下发的控制策略。
APP侧输出状态的方式I
参见图2，其给出了计算所有室内机的状态的交集及APP侧输出交集的流程图。
S21：云平台根据线控器标识位识别线控器。
例如，如上所述的，根据线控器标识位flag1识别1#线控器；根据线控器标识位flag2识别2#线控器。
S22：获取各线控器所连接的室内机的状态。
S221：根据所识别到的1#线控器，获取1#线控器所控制的室内机的状态。
识别到1#线控器连接的11#室内机和12#室内机。
获取到11#室内机的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)，即，11#状态集。
获取到12#室内机的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)，即，12#状态集。
S222：根据所识别到的2#线控器，获取2#线控器所控制的室内机的状态。
识别2#线控器连接的21#室内机、22#室内机和23#室内机。
获取到21#室内机的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠、自清洁、健康)，即，21#状态集。
获取到22#室内机的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠、自清洁、森林风)，即，22#状态集。
获取到23#室内机的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠、自清洁、辅热、加湿)，即，23#状态集。
需要说的是，室内机具有各自的地址号，且线控器的线控器标识位是与室内机的地址号绑定的。
S23：计算各线控器所连接的所有室内机的状态的交集。
S231：计算1#线控器下11#室内机和12#室内机的状态的交集。
即，11#室内机的11#状态集和12#室内机的12#状态集的交集：{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)}。
S232：计算2#线控器下21#室内机、22#室内机和23#室内机的状态的交集。
即，21#室内机的21#状态集、22#室内机的22#状态集、和23#室内机的23#状态集的交集：{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠、自清洁)}。
S24：计算所有线控器下的状态的交集。
根据S23获知，1#线控器下的交集{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)}，记为1#状态集。
2#线控器下的交集{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠、自清洁)}，记为2#状态集。
因此，1#线控器下的状态和2#线控器下的状态的交集为1#状态集和2#状态集的交集，即，{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)}。
S25：APP侧输出交集中的状态。
APP启动后，拉取云平台上的交集中的状态，在APP侧展示状态控制界面。
在S24中输出交集为{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)}，因此，APP侧输出开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)，并在APP侧生成交集中状态的控制界面。
如上所述，1#线控器上显示如下交集中的状态：{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)}；2#线控器上显示如下交集中的状态：{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠、自清洁)}；APP侧显示如下交集中的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)。
可知，APP侧显示的任一状态均包含在任一线控器上显示的状态中。
因此，APP侧下发至任一线控器的控制状态的指令都能被线控器响应，实现通过APP达到控制空调的目的。
需要说明的是，该APP侧表示安装有APP的智能类设备，包括手机、平板电脑(PAD)或电脑等。
该APP是能够监控并控制空调器的应用程序。
APP侧输出状态的方式II
参见图3，其给出了计算所有室内机的状态的交集及APP侧输出交集的流程图。
S31：云平台根据线控器标识位识别线控器。
例如，如上所述的，根据线控器标识位flag1识别1#线控器；根据线控器标识位flag2识别2#线控器。
S32：获取各线控器所连接的室内机的状态。
S321：根据所识别到的1#线控器，获取1#线控器所控制的室内机的状态。
识别到1#线控器连接的11#室内机和12#室内机。
获取到11#室内机的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)，即，11#状态集。
获取到12#室内机的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)，即，12#状态集。
S322：根据所识别到的2#线控器，获取2#线控器所控制的室内机的状态。
识别2#线控器连接的21#室内机、22#室内机和23#室内机。
获取到21#室内机的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠、自清洁、健康)，即，21#状态集。
获取到22#室内机的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠、自清洁、森林风)，即，22#状态集。
获取到23#室内机的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠、自清洁、辅热、加湿)，即，23#状态集。
需要说的是，室内机具有各自的地址号，且线控器的线控器标识位是与 室内机的地址号绑定的。
S33：计算所有线控器所连接的所有室内机的状态的交集。
计算11#室内机的11#状态集、12#室内机的12#状态集、21#室内机的21#状态集、22#室内机的22#状态集、和23#室内机的23#状态集的交集。
即，{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)}。
S34：APP侧输出交集中的状态。
APP启动后，拉取云平台上的交集中的状态，在APP侧展示状态控制界面。
在S33中输出交集为{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)}，因此APP侧输出开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)，并在APP侧生成交集中状态的控制界面。
如上同样能够实现在APP侧下发至任一线控器的控制状态的指令都能被线控器响应，实现通过APP达到控制空调的目的。
APP侧输出状态的方式II
在空调系统中存在一个1#线控器，且1#线控器控制多个室内机，例如，11#室内机和12#室内机，通过如上所述计算所有室内机的状态的交集的方式，APP侧显示的状态的交集与线控器显示的状态的交集是一致的，如此，实现通过APP对空调器的状态控制一致性。
S21'：云平台线控器标识位识别线控器。
例如，如上所述的，根据线控器标识位flag1识别1#线控器。
S22'：获取线控器所连接的室内机的状态。
根据所识别到的1#线控器，获取1#线控器所控制的11#室内机的状态和12#室内机的状态。
11#室内机的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)，即，11#状态集。
12#室内机的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)，即，12#状态集。
S23'：计算线控器所连接的所有室内机的状态的交集。
即，11#室内机的11#状态集和12#室内机的12#状态集的交集：{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)}。
S24'：APP侧输出交集中的状态。
APP启动后，拉取云平台上的交集中的状态，在APP侧展示状态控制界面。
在S23中输出交集为{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)}，因此，APP侧输出开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)，并在APP侧生成交集中状态的控制界面。
如上所述，1#线控器上显示如下交集中的状态：{开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)}；APP侧显示如下交集中的状态：开关机、(制冷/制热/除湿)模式、风量、附加功能(节能、静音、睡眠)。
可知，APP侧显示的状态与1#线控器上显示的状态一致。
因此，APP侧下发至1#线控器的控制状态的指令都能被1#线控器响应，实现通过APP达到控制空调的目的。
本申请的空调控制系统，不会出现通过APP下发控制指令而产生线控器处于集中控制的问题，从不会出现通过APP不能控制空调器的情况，因此用户体验度好。
以上实施例仅用以说明本申请的技术方案，而非对其进行限制；尽管参照前述实施例对本申请进行了详细的说明，对于本领域的普通技术人员来说，依然可以对前述实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或替换，并不使相应技术方案的本质脱离本申请所要求保护的技术方案的精神和范围。
