本实施例中，通过将室外压缩机驱动单元115和智能功率单元113设置于空调内机控制板，在空调内机控制板实现对空调外机20主要做功组件的驱动控制，优化了空调外机20主要做功组件的控制驱动单元的工作环境，消除了恶劣环境对空调外机20主要做功组件的控制驱动单元的负面影响，延长了主要做功组件的控制驱动单元的使用寿命，降低了主要做功组件的控制驱动单元故障时的维修难度。
具体实现时，如图1所示，空调外机20中除了压缩机22，还可以有各种传感器(例如用于检测外部环境参数的外环传感器26、用于检测外盘参数的外盘传感器24)以及其它做功组件(例如室外风机27和四通阀25)，本实施例中的空调内机控制板对应其中的做功组件，还可以进一步设置室外风机驱动单元116和四通阀驱动单元117；室内主控单元111还用于生成室外风机控制指令和四通阀控制指令；室外风机驱动单元116设置于内机板体110，与室内主控单元111连接并从室内主控单元111接收室外风机控制指令，用于根据室外风机控制指令控制室外风机27运转；四通阀驱动单元117设置于内机板体110，与室内主控单元111连接并从室内主控单元111接收四通阀控制指令，用于根据四通阀控制指令控制四通阀25运转；供电单元112的电源输入端还与室外风机驱动单元116以及四通阀驱动单元117连接；智能功率单元113还用于通过室外风机驱动单元116和供电单元112为室外风机27供电，通过四通阀驱动单元117和供电单元112为四通阀25供电。在主要做功组件之外，通过将次要做功组件的控制驱动单元设置于空调内机控制板的内机板体110，将空调内机10和空调外机20的做功组件的控制驱动均在内机完成，优化了空调外机20的做功组件的控制驱动单元的工作环境，消除了恶劣环境对空调外机20的做功组件的控制驱动单元的负面影响，延长了做功组件的控制驱动单元的使用寿命，降低了故障时的维修难度。
对于本申请实施例中的空调内机控制板，为实现对空调外机20的外机控制指令的传输，还设置有第一通讯单元，第一通讯单元设置于内机板体110并与室内主控单元111连接，第一通讯单元用于将室内主控单元111的外机控制指令发送到空调外机20，并接收空调外机20的传感器数据。通过第一通讯单元，可以减少空调内机10与空调外机20之间的多点连线，简化生成工序环节和安装时的接线操作。
基于空调内机控制板对空调外机20的控制驱动仅有对压缩机22的控制驱动的方案，本申请实施例对应提供了一种空调控制系统，请参考图2，其是本申请实施例提供的一种空调控制系统应用于空调的连接示意图。如图2所示，该空调控制系统包括空调内机控制板和外机控制小板，空调内机控制板用于空调内机10，外机控制小板用于空调外机20；空调内机控 制板包括内机板体110、室内主控单元111、供电单元112、室内风机驱动单元114、智能功率单元113和室外压缩机驱动单元115；室内主控单元111设置于内机板体110，用于生成压缩机控制指令和室内风机控制指令；室外压缩机驱动单元115设置于内机板体110，与室内主控单元111连接并从室内主控单元111接收压缩机控制指令，用于根据压缩机控制指令控制压缩机22运转；室内风机驱动单元114设置于内机板体110，与室内主控单元111连接并从室内主控单元111接收室内风机控制指令，用于根据室内风机控制指令控制室内风机121运转；供电单元112设置于内机板体110，供电单元112的电源输入端与室外压缩机驱动单元115连接；智能功率单元113设置于内机板体110，接入市电电源并与室外压缩机驱动单元115和室内风机驱动单元114连接，用于通过室外压缩机驱动单元115和供电单元112为压缩机22供电，通过室内风机驱动单元114为室内风机121供电；外机控制小板包括外机板体210、室外主控单元211、四通阀驱动单元117和室外风机驱动单元116，室外主控单元211、四通阀驱动单元117和室外风机驱动单元116均设置于外机板体210；室外主控单元211与室内主控单元111通讯连接，用于接收室内主控单元111发送的外机控制指令，并向室内主控单元111发送传感器数据；室外主控单元211用于生成室外风机控制指令和四通阀控制指令；室外风机驱动单元116与室外主控单元211连接并从室外主控单元211接收室外风机控制指令，用于根据室外风机控制指令控制室外风机27运转；四通阀驱动单元117与室外主控单元211连接并从室外主控单元211接收四通阀控制指令，用于根据四通阀控制指令控制四通阀25运转。
本申请实施例中的空调控制系统应用于空调时，空调内机控制板用于空调内机10时，与空调内机10的各种传感器(例如用于检测内部环境参数的内环传感器124、用于检测内翘片盘管参数的内盘传感器123)和各种做功组件(例如室内风机121、步进电机122)相连，具体在内机板体110上设置对应的接口，空调内机10的各种传感器和做功组件通过对应的接口连接到供电单元112实现供电。外机控制小板用于空调外机20时，与空调外机20的各种传感器(例如用于检测外部环境参数的外环传感器26、用于检测外盘参数的外盘传感器24)以及压缩机22之外的其它做功组件(例如室外风机27和四通阀25)相连，具体在外机板体210上设置对应的接口，各种传感器和压缩机22之外的其它做功组件通过对应的接口与外机控制小板连接。空调内机控制板和外机控制小板组成的空调控制系统，在空调外机20保留室外主控单元211和对部分做功组件(室外风机27和四通阀25)的驱动控制时，将对应驱动单元(室外风机驱动单元116和四通阀驱动单元117)与室外主控单元211设置于外机板体210上组成外机控制小板，由外机控制小板与空调内机控制板协作对空调进行控制，简化了空调内机10与空调外机20之间的连线。
本申请实施例中的空调控制系统，空调内机控制板还包括第一通讯单元，第一通讯单元设置于内机板体110并与室内主控单元111连接；外机控制小板还包括第二通讯单元，第二通讯单元设置于外机板体210并与室外主控单元211连接；室内主控单元111通过第一通讯单元以及第二通讯单元与室外主控单元211进行数据传输。在该具体实施方式中，如图2所示，外机控制指令和传感器数据具体通过第一通讯单元经由通信线(S)以及第二通信单元与室外主控单元进行收发。在图2所示的控制布局方式下，空调内机10向压缩机22提供三相电源进行供电，另外与空调外机20连接零线(N)和火线(L)，以对室外风机27和四通阀25进行供电。
通过外机控制小板对传感器数据和外机控制指令进行传输，对于通过弱电信号进行传输的数据，可以提高数据传输的准确性，并且减少空调外机20和空调内机10之间的连线数量。在具体驱动时，市电接入到智能功率单元113，经过处理后由室内做功组件的驱动单元驱动对应的做功组件；对于室外做功组件，则通过供电单元112给到空调外机20。
基于空调内机控制板对空调外机20的控制驱动包括对所有做功组件进行驱动的方案，本申请实施例对应提供了另一种空调控制系统，在该空调控制系统中，其是对应空调内机控制 板进一步组合多根弱电线和两根电源线作为空调控制系统，该空调控制系统应用于空调时的实施状态可以参考图1，具体实现方式在空调内机控制板对应实施例中已有描述，在此不重复说明。
本申请实施例另外还提供了一种空调内机10，该空调内机10包括前文任一实施例中的空调内机控制板。具体实现本申请实施例中的空调内机10时，如果对空调外机20中的做功组件(四通阀25、室外风机27和压缩机22)的驱动均在空调内机控制板中实现，如图1所示，空调外机20中除了压缩机22，还可以有各种传感器(例如用于检测外部环境参数的外环传感器26、用于检测外盘参数的外盘传感器24、用于检测排气状态的排气传感器23)，对应在适配于该空调内机10的空调外机20中，各个传感器通过对应的弱电线进行传感器数据的传输(例如外环传感器26对应的OAT线，外盘传感器24对应的OPT线，排气传感器23对应的Td线)。四通阀驱动单元117设置于内机板体110，室外风机驱动单元116设置于内机板体110；四通阀驱动单元117和室外风机驱动单元116分别对应设置有继电器，继电器通过分别对应于四通阀25和室外风机27的火线(室外风机27对应火线FAN，四通阀25对应火线4-WAY)以及共用的零线(N)，形成分别对应于四通阀25和室外风机27的供电回路。通过分别构建供电回路，可以实现在空调内机10对空调外机20中的室外风机27和四通阀25的独立控制。
整体而言，本申请实施例中的空调内机，在前文所述空调内机控制板和空调控制系统的基础上，对应于空调中的空调内机和空调外机，空调内机包括前文所述的空调内机控制板；外机包括压缩机、四通阀和室外风机，四通阀对应设置有四通阀驱动单元，室外风机对应设置有室外风机驱动单元；根据空调内机控制板的具体实现方式，对应仅在空调内机中设置空调内机控制板，或对应在空调内机和空调外机中综合设置空调控制系统。具体的设置方式在前文已有说明。本申请实施例中，将使用寿命受环境影响或者受环境影响较大的驱动单元配置到空调内机，消除了恶劣环境对空调外机主要做功组件的控制驱动单元的负面影响，延长了主要做功组件的控制驱动单元的使用寿命，降低了主要做功组件的控制驱动单元故障时的维修难度。
各个做功组件对应驱动单元的实现方式在相关技术已有实现，不是本方案的改进重点，在此不做赘述。
本申请实施例中的空调内机控制板具体应用于空调内机10时，空调内机控制板中，设置于内机板体110上的室内主控单元111和多个驱动单元的发热相对比较集中，为解决发热集中可能带来的不良影响，请参考图3-图5，本申请实施例进一步提供了三种在空调内机10中对空调内机控制板的散热设计。
请参考图3，其是本申请实施例提供的内机板体110的第一种布局示意图，对应为在空调内机10中对空调内机控制板的第一种散热设计，如图所示，空调内机10还包括热管式散热器140，热管式散热器140的第一端部邻近内机板体110上的发热器件设置，热管式散热器140的第二端部延伸到空调内机10的内机换热器130的进风口或出风口。热管式散热器140利用金属良好的导热效果，将发热器件工作时发出的热量从第一端部导到第二端部，并利用空调本身的散热功能，在内机换热器130的进风口或出风口将第二端部的热量快速散入空气中，从而优化内机板体110上的散热效果。
请参考图4，其是本申请实施例提供的内机板体110的第二种布局示意图，对应为在空调内机10中对空调内机控制板的第二种散热设计，如图所示，空调内机10还包括风道150，风道150的进风口为空调内机10的外壳上的开口，风道150沿内机板体110上的发热器件设置，风道150的出风口设置于空调内机10的风腔。通过沿内机板体110上的发热器件设置的风道150，引导空气通过风道150进行流动，从而带走内机板体110上的发热器件发出的热量，实现发热器件的快速降温。在本方案中，风道150的管道可以为金属管。
请参考图5，其是本申请实施例提供的内机板体110的第三种布局示意图，对应为在空 调内机10中对空调内机控制板的第三种散热设计，如图所示，空调内机10还包括冷媒支管160，冷媒支管160沿内机板体110上的发热器件设置，冷媒支管160的两端连接于空调内机10的内机换热器130的冷媒管道。在本实施例中，冷媒支管160可以是适应于内机板体110的布局调整的一段冷媒管道；也可以是内机板体110适应于冷媒管道的原有布局，冷媒支管160是原有冷媒管道中对应于内机板体110的一段。
以上三种实现方式，通过空调本身的基础功能，在不增加功能模块的情况下，实现对内机控制板的散热优化，降低了内机控制板的散热实现成本。
