 本发明的实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
参照图1，图1是本申请各实施例涉及的空调器的硬件结构示意图。本申请实施例中，空调器可以包括处理器1001（例如中央处理器Central Processing Unit、CPU），通信总线1002，输入端口1003，输出端口1004，存储器1005。其中，通信总线1002用于实现这些组件之间的连接通信；输入端口1003用于数据输入；输出端口1004用于数据输出，存储器1005可以是高速RAM存储器，也可以是稳定的存储器（non-volatile memory），例如磁盘存储器，存储器1005可选的还可以是独立于前述处理器1001的存储装置。本领域技术人员可以理解，图1中示出的硬件结构并不构成对本申请的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
继续参照图1，图1中作为一种可读存储介质的存储器1005可以包括操作***、网络通信模块、应用程序模块以及空调器的控制程序。在图1所示的终端中，网络接口1004主要用于连接后台服务器，与后台服务器进行数据通信；用户接口1003主要用于连接客户端（用户端），与客户端进行数据通信；而处理器1001可以用于调用存储器1005中存储的空调器的控制程序。
在本实施例中，空调器包括：存储器1005、处理器1001及存储在所述存储器1005上并可在所述处理器1001上运行的空调器的控制程序，其中，处理器1001调用存储器1005中存储的空调器的控制程序时，并执行以下操作：

在所述当前室外温度大于预设室外温度时，控制压缩机启动运行，并获取压缩机运行第一预设时间后的第一室内换热器温度；
根据所述第一室内换热器温度，对所述空调器的外风机运行状态进行调整。
基于图1所示的硬件结构，本申请第一实施例提供了一种空调器的控制方法。
需要说明的是，本实施例中提出的上述空调器指代定频空调器，即空调器的压缩机的转速不可变，为定频压缩机，具体地，参考图2，图2为本申请所涉及的空调器的构造图，如图2所示，空调器分为室外侧及室内侧，其中室内侧包括内风机1、室内换热器2及用于检测室外换热器2温度的第一管路温度传感器3，其中，内风机1用于带动室内空气经过室内换热器，使得室内空气与室内换热器的盘管内的冷媒进行热交换，而室内换热器2制冷时作为蒸发端，对冷媒起到吸热作用，制热时作为冷凝端，对冷媒起到散热作用，进一步地，室外侧依次包括转速不可变的压缩机4、气液分离器5、四通阀6、室外换热器7、用于检测室外换热器7的温度的第二管路温度传感器8、第一外风机9、第二外风机10、用于过滤空调器冷媒管路中的杂质，避免杂质进入节流部件，导致节流效果变差或者脏堵的第一过滤器11、节流阀12及用于过滤空调器冷媒管路中的杂质，避免杂质进入节流部件，导致节流效果变差或者脏堵的第二过滤器13。
其中，本实施例中，节流阀12由制冷节流阀和制热节流阀组成，需要说明的是，制热节流阀在空调器制热时，起到节流降压的作用，在空调器制冷时，其不起节流作用，即单向节流，反向不节流，同理制冷节流阀在空调器制冷时，起到节流降压的作用，在空调器制热时，其不起节流作用，即单向节流，反向不节流。
其中，本实施例中，第一外风机9为设置于空调器的室外换热器7处的风机，第二外风机10也为设置于空调器的室外换热器7处的风机，其中，上述外风机用于带动室外空气经过室外换热器7，使得室外空气与室外换热器7管内的冷媒进行热交换。
进一步需要说明的是，本实施例中，空调器的室外换热器7处的外风机数量不作限制，换句话说，本实施例中，在空调器的室外换热器7的竖直方向上还可安装有其他外风机，本实施例对此不作限制。
进一步地，本实施例中，为了灵活调控室外换热器的散热量，可将上述第一外风机9的排风口朝向室外换热器7的上部，由此通过上述第一外风机9将室外空气带动至室外换热器7的上部区域处，以进行热交换，同时还可将上述第二外风机10的排风口朝向室外换热器7的下部，则基于第一外风机9及第二外风机10的协同配合，可达到灵活调控室外换热器的散热量的目的。
需要说明的是，本实施例中的外风机可位于室外换热器7的同一侧，还可以位于室外换热器7的不同侧，本实施例对此不作限制。
基于图2所示的空调器，提出本申请的空调器的控制方法，参照图3，图3为本申请空调器的控制方法第一实施例的流程示意图。
本申请实施例提供了空调器的控制方法的实施例，需要说明的是，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
具体地，本实施例空调器的控制方法包括：
步骤S10：在检测到空调器进入制热模式时，获取所述空调器所处室外环境的当前室外温度；
需要说明的是，本实施例的执行主体是上述图2所涉及的空调器，本实施例在此不再赘述。
应当理解的是，室外温度可以是通过预先设置在空调器室外侧的温度传感器获取到的，其中，温度传感器的安装位置可位于空调器室外侧任意位置，例如空调器室外侧的机壳内部或外部，本实施例对此不作限制。
步骤S20：在所述当前室外温度大于预设室外温度时，控制压缩机启动运行，并获取压缩机运行第一预设时间后的第一室内换热器温度；
具体而言，上述预设室外温度指代用于区分当前空调器的制热状态的预先设定的特定温度值，其中，制热状态指代高温制热及非高温制热，即当室外温度大于该预设室外温度时，空调器处于高温制热，当室外温度小于或等于该预设室外温度时，空调器处于非高温制热。
值得注意的是，在空调器由待机模式、关机模式或制冷模式进入制热模式时，压缩机排出的高温高压气体冷媒流经四通阀，进入到室内换热器侧进行散热后，经过过滤器，之后经过制热节流阀节流，形成低温低压冷媒，冷媒再进入到室外侧的室外换热器进行吸热蒸发，再流入气液分离器中进行汽液分离后，气态冷媒回到压缩机中进行循环，液体冷媒储存在气液分离器中，容易理解地，在室外温度相对较高的情况下，由于空调器的内侧制热需求量小，则当空调器的外风机与压缩机同时启动时，由于定频的压缩机此时无法通过改变转速来减少热量的输出，则空调器容易出现运行压力过高，而进行保护停机的状态，因此本实施例中先通过环境温度传感器获取室外环境的室外温度，再通过室外环境温度来执行相应的控制策略。
具体地，在实际应用中，若检测到空调器的室外温度大于预先设定的特定温度值，则表明当前处于高温制热，因此本实施例中为了避免空调器的运行压力过大，先使压缩机进入运行状态，待压缩机启动运行第一预设时间之间后再控制空调器的外风机启动。
进一步地，为了提高空调器运行的稳定性，本实施例中，在压缩机启动运行时长达到第一预设时间时，通过第一管路温度传感器获取室内换热器的温度值，接着再通过该温度值来确定空调器的外风机的调控策略。
应当理解的是，上述第一预设时间可以是预先设定的某一特定时间值，例如10s、15s等。
应当理解的是，上述第一预设时间还可以是空调器的冷媒管路中的冷媒流向切换至制热流向所消耗的时间，需要说明的是，在压缩机制热启动阶段，四通阀存在延时启动状况导致制热模式初始阶段四通阀实际处于制冷状态，从而使得室内换热器温度处于下降阶段，当四通阀切换到制热状态时，四通阀处的冷媒反向对撞，室内换热器温度上升缓慢，从而使得空调器的压力逐渐变大，进而导致压缩机停机，因此本实施例中在压缩机运行达到第一预设时间后，通过第一管路温度传感器获取室内换热器的温度值，从而根据该温度值来执行相应的控制策略。
步骤S30：根据所述第一室内换热器温度，对所述空调器的外风机运行状态进行调整。
具体而言，上述外风机指代空调器室外侧区域的风机，如图3所示的第一外风机，或者第二外风机，此外，本实施例中，上述外风机还可包括图3中所示之外的其他外风机，本实施例对此不作限制，其中，本实施例以如图3所示的外风机为代表进行说明。
该步骤中，由于室外换热器位于第一外风机的排风口与第二外风机的吸风口之间，因此可通过调整外风机的运行状态来调整流经室外换热器处的室外空气的风量，来调整室外换热器的换热量，进而达到调节空调器的运行压力的目的。
具体地，在实际的应用中，由于压缩机制热启动阶段，四通阀存在延时启动状况导致室内换热器温度先处于下降阶段，再处于缓慢上升阶段，因此本实施例中，在进行调整时，先判断第一室内换热器温度（即通过第一管路温度传感器获取到的温度值）是否达到外风机启动运行条件，例如第一预设温度为48℃，则当检测到室内换热器温度的温度值小于第一预设温度48℃时，则判定达到外风机启动运行条件，此外当检测到室内换热器温度的温度值为48℃，即等于第一预设温度48℃时，也判定达到外风机启动运行条件，则在室内换热器温度达到外风机启动运行条件时，控制空调器的上述两个外风机同时启动运行。
具体而言，上述第一预设温度用于衡量室外换热器的换热量是否偏低，当检测到第一室内换热器温度达到外风机启动运行条件时，表明当前室内换热器的盘管温度偏低，空调器的出风口处的出风温度低，因此室外换热器需要加强吸收热量传递到室内换热器，使空调器的出风口处的出风温度达到用户要求。
因此本实施例中，在第一室内换热器温度达到外风机启动运行条件时，第一外风机、第二外风机同时启动运行，由此通过同时运行的外风机带动大量室外空气流经室外换热器，进而加强室外换热器吸收的热量。
在一应用场景中，为了提高换热效率，上述第二外风机的吸风口与第一外风机的排风口相对，且室外换热器位于第一外风机的排风口与第二外风机的吸风口之间，从而在第二外风机的吸风口与第一外风机的排风口之间形成散热风道，而室外换热器位于该散热风道上，由此可通过第二外风机的抽吸力的作用下，使得第一外风机排出的风全部流过该散热风道，从而可以极大地提高室外换热器的换热效率。
进一步地，为了避免在同时启动上述两个外风机运行以加强室外换热器吸收的热量时，室外换热器吸收的热量过多从而导致空调器换热强劲，该步骤中可先控制上述两个外风机均以阶梯式转速启动运行，比如基于预先设定好的外风机转速挡位进行阶梯式转速启动运行，例如以第一外风机举例说明，第一外风机转速挡位依次分为最低档、中档及最高档，则在初次启动运行第一外风机时，控制第一外风机先以最低档启动运行，当再次检测到需要加强室外换热器吸收的热量时，再控制第一外风机以中档启动运行，以此类推。
进一步地，为了提高空调器调控的精准性，在同时启动上述两个外风机运行时，上述两个外风机的转速均可随着第一室内换热器温度的增大而减少，例如以第一外风机举例说明，在检测到第一室内换热器温度达到外风机启动运行条件后，计算出第一室内换热器温度与第一预设温度之间的温度差值为5℃，则控制第一外风机以40rpm/min启动运行，当温度差值为10℃，则控制第一外风机以80rpm/min启动运行，当温度差值为15℃，则控制第一外风机以120rpm/min启动运行，以此类推。
在另一应用场景中，在执行上述步骤S30，还包括：若第一室内换热器温度大于或等于第二预设温度，则控制空调器的外风机停止运行。
具体而言，上述第二预设温度用于衡量室外换热器的换热量是否偏高，需要说明的是，当室外换热器的换热量偏高时，表明当前空调器换热强劲，空调器的运行压力高，因此为了避免空调器的运行压力继续升高从而导致压缩机停机，可以通过控制空调器的外风机停止运行，从而减少室外换热器的换热量，进而降低空调器的运行压力。
进一步地，为了在空调器稳定运行期间提高空调器的制热效果，可在第一室内换热器温度大于第一预设温度，且第一室内换热器温度小于第二预设温度时，开启一个外风机，即开启空调器的第一外风机启动运行，或者开启空调器的第二外风机，以带动少量室外空气流经换热器，与室外换热器进行部分换热。
进一步地，为了避免在启动一个外风机以加强室外换热器吸收的热量时，室外换热器吸收的热量过多从而导致空调器换热强劲，该步骤中可先控制空调器的一个外风机以阶梯式转速启动运行，其中需要说明的是，本实施例中外风机以阶梯式转速启动运行的步骤可同上述第一实施例中阶梯式转速启动运行的步骤一样，本实施例在此不再赘述。
应当理解的是，以上仅为举例说明，对本申请的技术方案并不构成任何限制，本领域的技术人员在实际应用中可以基于需要进行设置，此处不再一一列举。
在本实施例中，在室外温度相对较高的情况下，先控制压缩机开机运行，接着在根据室内换热器温度对外风机进行调控，由此控制压缩机与外风机非同时启动，并通过外风机的调控来减少热量的输出，进而降低空调器运行压力，从而避免空调器频繁出现保护停机。
进一步地，基于本申请空调器的空调器的控制方法的第一实施例，提出本申请空调器的控制方法第二实施例。
参照图4，图4为本申请空调器的电控冷却方法第二实施例的流程示意图；
所述空调器的电控冷却方法第二实施例与所述空调器的电控冷却方法第一实施例的区别在于，上述步骤S30之后，还包括：
步骤S40：获取所述空调器以调整后的外风机运行状态运行第二预设时间后的第二室内换热器温度，并将所述第二室内换热器温度作为所述第一室内换热器温度；
步骤S50：继续执行所述根据所述第一室内换热器温度，对所述空调器的外风机运行状态进行调整的步骤。
具体而言，上述第二预设时间可以是预先设定的某一特定时间值，例如10s、20s等，其中，上述第二预设时间可以和上述第一实施例中的第一预设时间相等，也可以和上述第一实施例中的第一预设时间不相等，本实施例对此不做限制。
该步骤中，应当理解地，为了避免压缩机在运行期间频繁启停，在获取室内换热器温度之后，继续执行上述步骤，从而通过执行上述步骤使空调器的运行压力处于正常运行压力范围内。
此外，应当注意的是，在空调器进入制热模式后会对外风机进行调整，因此再次对外风机进行调整之前，空调器的外风机状态存在以下至少三种状态：上述两个外风机均处于运行状态、第一外风机或第二外风机处于运行状态及上述两个外风机均处于停止运行状态，因此本实施例中，在执行上述步骤S50时，本实施例根据第一室内换热器温度将上述步骤划分为三种情况具体说明。
第一种情况：若所述第一室内换热器温度小于或等于第一预设温度。
该步骤中，若检测当前上述两个外风机均处于运行状态，例如一个外风机以40rpm/min启动运行，另一个外风机以80rpm/min启动运行，则可以将以40rpm/min启动运行的外风机增大至80rpm/min，同时将以80rpm/min启动运行的外风机增大至120rpm/min。
进一步需要注意的是，在增大外风机的转速时，需要先判断空调器的外风机转速是否达到预设限制转速，即当前外风机转速是否可以继续增大，若当前外风机转速不可以继续增大，则降低空调器的内风机的转速。
具体而言，上述预设限制转速指代外风机的最高转速，容易理解地，当空调器的外风机转速不可以继续增大时，本实施例中还可以通过降低内风机转速来减少室内换热器的散热量，进而提高室内换热器的盘管温度。
此外，在一些实施例中，若检测当前上述两个外风机均不处于运行状态均不处于运行状态时，则控制上述两个外风机启动运行，需要说明的是，本实施例中控制上述两个外风机启动运行的步骤同上述第一实施例中的步骤S30一样，本实施例在此不再赘述。
进一步地，在一些实施例中，若检测当前上述两个外风机中其中一个外风机处于运行状态，例如第一外风机处于运行状态，或者第二外风机均处于运行状态，则在此种情况下，可以是在开启另一个处于关机状态的外风机启动运行，其中，在控制另一个外风机启动运行时可以是控制该外风机以阶梯式转速启动运行，还可以是基于当前处于运行状态的外风机的运行转速确定另一个外风机启动运行时的转速。
为了便于理解，本实施例对上述控制另一个外风机启动运行的步骤举例说明。
例如，当第一预设温度为48℃，第二预设温度为54℃，当前空调器的第一外风机处于停止运行状态，第二外风机以中档转速80rpm/min正在运行，则若检测到处于48℃至54℃之间时，对于第一外风机的控制，本实施例中可以是让第一外风机先以最低档转速40rpm/min启动运行，还可以是让第一外风机以与第二外风机相同的转速80rpm/min运行，本实施例对此不作限制。
第二种情况：若所述第一室内换热器温度大于第一预设温度，且所述第一室内换热器温度小于第二预设温度。
该步骤中，当检测到第一外风机处于运行状态，第二外风机处于停机状态时，则增大可空调器的第一外风机的转速，或者，当检测到第二外风机处于运行状态，第一外风机处于停机状态时，则增大第二外风机的转速。
此外，在另一种应用场景中，若检测到空调器的上述两个外风机均处于停止运行状态，则可以驱动其中一个外风机启动运行，例如驱动空调器的第一外风机启动运行，需要说明的是，本实施例中外风机启动运行的步骤同上述第一实施例中的步骤S30一样，本实施例在此不再赘述。
第三种情况：若所述第一室内换热器温度大于或等于第二预设温度。
该步骤中，当室内换热器的温度属于第三种情况时，表明当前室外换热器的换热量偏高，当前空调器换热强劲，空调器的运行压力高，因此为了避免空调器的运行压力继续升高从而导致压缩机停机，控制空调器的上述两个外风机均停止运行，从而减少室外换热器的换热量，进而降低空调器的运行压力。
进一步地，在一些实施例中，当前空调器的外风机可能已经处于停止运行状态，则为了减缓室外换热器的换热量，本实施例中可以增大空调器的内风机的转速，由此通过加大室内换热器的散热量来减缓室外换热器的换热量偏高带来的影响。
本实施例中，在空调器进入制热模式后再次循环执行对上述步骤，由此通过多次循环步骤使空调器在运行过程中能够稳定运行，避免压缩机频繁启停产生噪音。
此外，本实施例还提供一种空调器的控制装置。参照图5，图5为本申请
空调器的控制装置一实施例的功能模块示意图。
具体地，参照图5，所述空调器的控制装置包括：
获取模块10，在检测到空调器进入制热模式时，获取所述空调器所处室外环境的当前室外温度；
应当理解的是，室外温度可以是通过预先设置在空调器室外侧的温度传感器获取到的，其中，温度传感器的安装位置可位于空调器室外侧任意位置，例如空调器室外侧的机壳内部或外部，本实施例对此不作限制。
控制模块20，用于在所述当前室外温度大于预设室外温度时，控制压缩机启动运行，并获取压缩机运行第一预设时间后的第一室内换热器温度；
具体而言，上述预设室外温度指代用于区分当前空调器的制热状态的预先设定的特定温度值，其中，制热状态指代高温制热及非高温制热，即当室外温度大于该预设室外温度时，空调器处于高温制热，当室外温度小于或等于该预设室外温度时，空调器处于非高温制热。
值得注意的是，在空调器由待机模式、关机模式或制冷模式进入制热模式时，压缩机排出的高温高压气体冷媒流经四通阀，进入到室内换热器侧进行散热后，经过过滤器，之后经过制热节流阀节流，形成低温低压冷媒，冷媒再进入到室外侧的室外换热器进行吸热蒸发，再流入气液分离器中进行汽液分离后，气态冷媒回到压缩机中进行循环，液体冷媒储存在气液分离器中，容易理解地，在室外温度相对较高的情况下，由于空调器的内侧制热需求量小，则当空调器的外风机与压缩机同时启动时，由于定频的压缩机此时无法通过改变转速来减少热量的输出，则空调器容易出现运行压力过高，而进行保护停机的状态，因此本实施例中先通过环境温度传感器获取室外环境的室外温度，由此通过室外环境温度来执行相应的控制策略。
具体地，在实际应用中，若检测到空调器的室外温度大于预先设定的特定温度值，则表明当前处于高温制热，因此本实施例中为了避免空调器的运行压力过大，先使压缩机进入运行状态，待压缩机启动运行第一预设时间之间后再控制空调器的外风机启动。
进一步地，为了提高空调器运行的稳定性，本实施例中，在压缩机启动运行时长达到第一预设时间时，通过第一管路温度传感器获取室内换热器的温度值，接着再通过该温度值来确定空调器的外风机的调控策略。
应当理解的是，上述第一预设时间可以是预先设定的某一特定时间值，例如10s、15s等。
应当理解的是，上述第一预设时间还可以是空调器的冷媒管路中的冷媒流向切换至制热流向所消耗的时间，需要说明的是，在压缩机制热启动阶段，四通阀存在延时启动状况导致制热模式初始阶段四通阀实际处于制冷状态，从而使得室内换热器温度处于下降阶段，当四通阀切换到制热状态时，四通阀处的冷媒反向对撞，室内换热器温度上升缓慢，从而使得空调器的压力逐渐变大，进而导致压缩机停机，因此本实施例中在压缩机运行达到第一预设时间后，通过第一管路温度传感器获取室内换热器的温度值，从而根据该温度值来执行相应的控制策略。
调整模块30，用于根据所述第一室内换热器温度，对所述空调器的外风机运行状态进行调整。
具体而言，上述外风机指代空调器室外侧区域的风机，如图3所示的第一外风机，或者第二外风机，此外，本实施例中，上述外风机还可包括图3中所示之外的其他外风机，本实施例对此不作限制，其中，本实施例以如图3所示的外风机为代表进行说明。
该步骤中，由于室外换热器位于第一外风机的排风口与第二外风机的吸风口之间，因此可通过调整外风机的运行状态来调整流经室外换热器处的室外空气的风量，来调整室外换热器的换热量，进而达到调节空调器的运行压力的目的。
具体地，在实际的应用中，由于压缩机制热启动阶段，四通阀存在延时启动状况导致室内换热器温度先处于下降阶段，再处于缓慢上升阶段，因此本实施例中，在进行调整时，先判断第一室内换热器温度（即通过第一管路温度传感器获取到的温度值）是否达到外风机启动运行条件，例如第一预设温度为54℃，则当检测到室内换热器温度的温度值小于第一预设温度54℃时，则判定达到外风机启动运行条件，此外当检测到室内换热器温度的温度值等于第一预设温度54℃时，也判定达到外风机启动运行条件，则在室内换热器温度达到外风机启动运行条件时，控制空调器的上述两个外风机同时启动运行。
具体而言，上述第一预设温度用于衡量室外换热器的换热量是否偏低，当检测到第一室内换热器温度达到外风机启动运行条件时，表明当前室内换热器的盘管温度偏低，空调器的出风口处的出风温度低，因此室外换热器需要加强吸收热量传递到室内换热器，使空调器的出风口处的出风温度达到用户要求。
因此本实施例中，在第一室内换热器温度达到外风机启动运行条件时，第一外风机、第二外风机同时启动运行，由此通过同时运行的外风机带动大量室外空气流经室外换热器，进而加强室外换热器吸收的热量。
在一应用场景中，为了提高换热效率，上述第二外风机的吸风口与第一外风机的排风口相对，且室外换热器位于第一外风机的排风口与第二外风机的吸风口之间，从而在第二外风机的吸风口与第一外风机的排风口之间形成散热风道，而室外换热器位于该散热风道上，由此可通过第二外风机的抽吸力的作用下，使得第一外风机排出的风全部流过该散热风道，从而可以极大地提高室外换热器的换热效率。
进一步地，为了避免在同时启动上述两个外风机运行以加强室外换热器吸收的热量时，室外换热器吸收的热量过多从而导致空调器换热强劲，该步骤中可先控制均以阶梯式转速启动运行，比如基于预先设定好的外风机转速挡位进行阶梯式转速启动运行，例如以第一外风机举例说明，第一外风机转速挡位依次分为最低档、中档及最高档，则在初次启动运行第一外风机时，控制第一外风机先以最低档启动运行，当再次检测到需要加强室外换热器吸收的热量时，再控制第一外风机以中档启动运行，以此类推。
进一步地，为了提高空调器调控的精准性，在同时启动上述两个外风机运行时，上述两个外风机的转速均可随着第一室内换热器温度的增大而减少，例如以第一外风机举例说明，在检测到后，计算出第一室内换热器温度与第一预设温度之间的温度差值为5℃，则控制第一外风机以40rpm/min启动运行，当温度差值为10℃，则控制第一外风机以80rpm/min启动运行，当温度差值为15℃，则控制第一外风机以120rpm/min启动运行，以此类推。
在另一应用场景中，在执行上述步骤S30，还包括：若第一室内换热器温度大于或等于第二预设温度，则控制空调器的外风机停止运行。
具体而言，上述第二预设温度用于衡量室外换热器的换热量是否偏高，需要说明的是，当室外换热器的换热量偏高时，表明当前空调器换热强劲，空调器的运行压力高，因此为了避免空调器的运行压力继续升高从而导致压缩机停机，可以通过控制空调器的外风机停止运行，从而减少室外换热器的换热量，进而降低空调器的运行压力。
进一步地，为了在空调器稳定运行期间提高空调器的制热效果，可在第一室内换热器温度大于第一预设温度，且第一室内换热器温度小于第二预设温度时，开启一个外风机，即开启空调器的第一外风机启动运行，或者开启空调器的第二外风机，以带动少量室外空气流经换热器，与室外换热器进行部分换热。
本实施例中，在室外温度相对较高的情况下，控制压缩机与外风机非同时启动，并根据室内换热器温度对外风机进行调控，由此使得压缩机通过外风机的调控来减少热量的输出，进而降低空调器运行压力，从而避免空调器频繁出现保护停机。
