进一步的，当空调电路为非低功耗待机电路时，在进入待机状态时，内机电路1控制外机电路2带电；否则，当空调电路为低功耗待机电路时，在进入待机状态时，内机电路1控制外机电路2断电。
空调为包含上述识别空调电路的装置的空调，包含了上述识别空调电路的装置的空调为非低功耗待机电路的空调时，在上电未开机状态下，内机电路1控制外机电路2带电；包含了上述识别空调电路的装置的空调为低功耗待机电路的空调时，在上电未开机状态下，内机电路1控制外机电路2断电。
下面通过具体的实施例对识别空调电路的方法、识别空调电路的装置及包含识别空调电路装置的空调的具体结构及识别原理进行详细的描述。
实施例一，参照图2，其为非低功耗待机的空调电路，包括内机电路1和外机电路2、电源火线L和电源零线N。电源火线L和电源零线N为内机电路1和外机电路2供电；内机电路1包括内机控制器8、内机通信模块3、限流电阻R1、第一二极管D1；外机电路2包括外机控制器9、外机通信模块7、外机通信接口4及外机零线10。内机控制器8连接内机通信模块3；内机通信模块3连接外机通信接口4； 限流电阻R1一端连接内机通信模块3，另一端连接第一二极管D1的负极；第一二极管D1的正极连接电源零线N；外机通信模块7分别与外机控制器9、外机零线10和外机通信接口4连接；外机零线10与电源零线N连接。在空调电路上电未开机状态下，内机通信模块3通过外机通信接口4与外机通信模块7通信连通，并接收来自外机通信模块7的信号后输出；内机控制器8作为内机通信模块输出信号获取模块5获取内机通信模块3的输出信号、并作为空调电路识别模块6对输出信号进行识别；由于内机通信模块3与外机通信模块7通信连通，所以内机通信模块3可以收到外机通信模块7的信号并输出脉冲信号；内机控制器8获取内机通信模块3输出的脉冲信号后可以判断空调电路为非低功耗待机电路；则在进入待机状态时内机控制器8控制外机电路2带电。
实施例二，参照图3，其为低功耗待机电路的空调电路，包括内机电路1、外机电路2、电源火线L和电源零线N。电源火线L和电源零线N为内机电路1和外机电路2供电；内机电路1包括内机控制器8、内机通信模块3、限流电阻R1、第一二极管D1及第一开关K1；外机电路2包括外机控制器9、外机通信模块7、第二开关K2、第三开关K3、正温度系数热敏电阻PTC及外机零线10。内机控制器8、内机通信模块3、限流电阻R1、第一二极管D1、电源零线N之间的连接方式参照实施例一；第一开关K1为两位开关，包括两个接线端，一个接线端连接外机通信接口4，另一个接线端连接第一二极管D1的正极；外机控制器9与外机通信模块7连接；第三开关K3为单刀双掷开关，其包括公共端11、第一端12、第二端13；公共端11连接外机通信接口4；第一端12连接外机零线10；第二端13连接外机通信模块7；第二开关K2为两位开关，其串联在电源零线N和外机零线10之间；正温度系数热敏电阻PTC串联在外机零线10和第一端12之间。在空调电路上电未开机状态下，内机控制器8控制第一开关K1断开；第二开关K2常态为断开，第三开关K3常态为其公共端11与第一端12连通、与第二端13断开。由于第二开关K2常态为断开，所以在上电后外机电路2为断电状态；且内机通信模块3与外机通信模块7处于断开状态。由于内机通信模块3与外机通信模块7处于断开状态，且外机电路2断电，所以内机通信模块3无法收到外机通信模块7的信号而输出脉冲信号，从而内机控制器8作为内机通信模块输出信号获取模块5获取不到内机通信模块3输出的脉冲信号，从而内机控制器8作为空调电路识别模块6识别空调电路为低功耗待机电路，从而在进入待机状态时内机控制器8继续控制第一开关K1断开，外机电路2无电，则第二开关K2继续为常态开状态，外机电路2保持断电状态。
当内机电路1收到开机指令后，内机控制器8控制第一开关K1闭合，使外机电路2上电；外机电路2通电后，外机控制器9控制第二开关K2闭合；然后，内机控制器8控制第一开关K1断开；然后，外机控制器9控制第三开关K3的公共端11与第二端13连通、与第一端12断开；完成开机，使空调电路进入正常工作状态。
当然，上述说明并非是对本发明的限制，本发明也并不仅限于上述举例，本技术领域的普通技术人员在本发明的实质范围内所做出的变化、改型、添加或替换，也应属于本发明的保护范围。
