本申请的实施方式
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。
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。
参照图2,图2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:在检测到空调器处于制冷模式时,获取空调器所处室内环境的第一室内温度、空调器所处室外环境的第一室外温度及空调器的第一设定温度;
步骤S20:根据所述第一室内温度、所述第一室外温度及所述第一设定温度,对空调器的导风叶开度进行调整。
需要说明的是,本实施例中提出的上述空调器指代可拆卸安装于板房上的空调器,参考图3,图3为本实施例中所涉及的空调器结构简易示意图,如图3所示,该空调器包括室内机100和室外机200,其中,室内机100与室外机200之间为不可拆卸连接,即本实施例中,该空调器为整体式空调,室内机100与室外机200之间不可拆卸,由此使得在板房上安装与拆除上述空调器时,普通用户无需专业人员的协助就可完成。
此外,在另一实施例中,为了减小空调器在室内占用的空间,上述室内机100和室外机200之间为可拆卸安装,以便用户能够随时根据需求将室内机100和室外机200拆开,分散体积和重量,搬运方便,此外,本实施例中,当室内机100和室外机200连接时,空调器为一体式空调,用户可直接将空调器放置在室内进行使用,也可以将空调器安装在活动板房的墙壁上,使室内机100的风口通向室内,室外机200的风口通向室外。此外室内机100与室外机200还可以分开,以使空调器作为分体式空调使用,室内机100安装在室内,室外机100安装在室外,从而减小空调器在室内占用的空间,节省室内空间。
具体而言,本实施例中的上述空调器的室内机100与室外机200之间通过冷媒管连通,其中,室内机100包括内机机壳、室内风轮和室内换热器,本实施例中,室内侧进风口设于内机机壳的前侧壁,室内侧出风口设于内机机壳的顶壁,室内换热器位于室内风轮与室内侧进风口之间,如此,室内换热器能够正面迎风,从而有利于换热器与室内进风充分换热,进一步提升换热效率,本实施例中,室内风轮用以驱动空气通过室内侧进风口进入,流经室内换热器后进入进风风道,再通过出风风道从室内侧出风口吹出,以对室内环境进行降温或升温,由于解决了夏季高温时,室内温度极高,空调器难以对室内进行降温的技术问题,通过利用室内风轮驱动高温空气通过室内侧进风口进入,进而达到快速降温的目的,进一步地,内机机壳内设有蜗壳和蜗舌,蜗壳与蜗舌在室内侧风轮的进风侧围设成进风风道,以使空气集中从进风风道进入,增大进风风压,蜗壳与蜗舌在室内侧风轮的出风侧围设成出风风道,以使空气集中从出风风道吹出,增大出风风压。
进一步地,本实施例中,上述空调器还包括外机机壳,其中,内机机壳的底部与外机机壳的顶部可拆卸连接。具体的,外机机壳开设有室外侧进风口和室外侧出风口,外机机壳内还安装有室外换热器和室外风轮,其中,室外风轮还可以为轴流风轮、离心室风轮等,室内换热器为蒸发器,室外换热器则为冷凝器,室外风轮驱动空气从室外侧进风口进入外机机壳内,流经冷凝器以对冷凝器进行散热后,再从室外侧出风口吹出。
另外,在一实施例中,上述内机机壳的底部与外机机壳的顶部可拆卸连接,如此,在内机机壳与外机机壳连接时,该空调器作为一体式空调使用;而在内机机壳相对外机机壳拆卸后,该空调器则可作为分体式空调使用,从而提高空调器使用场景的灵活性。
值得注意的是,本实施例中上述空调器指代可拆卸安装于板房上的空调器,由于板房的特征结构,在夏季高温情况下,空调器所处室内环境温度可能高于空调器所处室外环境温度,甚至在极端情况下,空调器所处室内环境温度可能会比空调器所处室外环境高十几摄氏度,因此若仅仅为开启空调器进行制冷,室内温度较高的情况下,仅仅利用空调制冷系统降温,在压缩机完全启动之前,制冷系统冷量输出很少,这个时间段内,室内温度仍然很高,人体舒适度很差,因此本实施例中,为了解决上述技术问题,通过利用上述室外风轮的负压作用,将空调器所处室内的高温空气快速抽出室外,达到快速降温的目的。因此,在另一实施例中,为了实现利用上述室外风轮的负压作用,将空调器所处室内的高温空气快速抽出室外,达到快速降温的目的,本实施例对上述空调器进一步做出改进,具体而言,本实施例中,采用在空调器的室内侧机壳处设有多个通孔300,具体地,如图4所示,在内机机壳的室内侧开设有多个通孔300,由此基于上述多个通孔300使室内侧的空气进入空调器的内部,从而通过上述多个通孔300使空调器所处室内的高温空气快速抽出室外,达到快速降温的目的。
此外,为了便于理解,参考图5,图5为本实施例中空调器所处室内空气的风流向示意图,其中,箭头指代风流向,空调器的室外风轮为轴流风轮400,由此利用轴流风轮400驱动空调器所处室内的高温空气从上述多个通孔300进入空调器内部,再从室外侧出风口吹出,从而实现在室内空气温度较高的情况下,将室内高温空气抽出到室外的目的。此外,轴流风轮400还驱动空调器所处室内的低温空气从室外侧进风口进入外机机壳内,再通过通孔排出至室外。
在另一实施例中,在室内温度不高的情况下,在通过上述多个通孔300使空调器所处室内的空气快速抽出室外时,空调器的制冷量存在一定量的损失,因此为了达到维持空调器的制冷量的目的,本实施例中,在设有多个通孔300处的空调器的内部对应位置装置有导风叶及用于驱动导风叶开度的步进电机,由此通过步进电机驱动导风叶的开度,来调控从上述多个通孔300进入空调器的内部的室内侧空气的空气量,由此来维持空调器的制冷量,例如,在室内温度不高的情况下,则可利用步进电机驱动导风叶关闭,进而避免空调器的室内侧空气通过上述通孔300进入空调器的内部,在室内温度很高的情况下,则可利用步进电机驱动导风叶打开,进而通过上述多个通孔300使空调器所处室内的空气快速抽出室外,达到快速降温的目的。
由此,基于本实施例上述的空调器的构造,提出本申请空调器的电控冷却方法,进而达到利用上述室外风轮的负压作用,将空调器所处室内的高温空气快速抽出室外,达到快速降温的目的。
应当理解地,在一些极端情况下,室内环境温度可能会比室外高十几摄,例如对于一些密闭不透风的板房,其在炎炎夏日的照射下板房内的温度很可能高于板房外的温度,因此此种情况下,若仅仅利用空调 制冷系统降温,在压缩机完全启动之前,制冷系统冷量输出很少,这个时间段内,室内温度仍然很高,并高于室外温度,因此本实施例中,为了实现快速温降,在检测到空调器处于制冷模式时,实时监测空调器所处室内环境的第一室内温度、空调器所处室外环境的第一室外温度,,可选地,在上述室内侧机壳处设置至少一个第一温度传感器,用于实时监测空调器所处室内环境的室外温度,在上述室外侧机壳处设置至少一个第二温度传感器,用于实时监测空调器所处室内环境的室外温度,从而在空调器所处室外环境的第一室外温度小于空调器所处室内环境的第一室内温度时,利用上述空调器的室内侧机壳处设的多个通孔及导风叶对温度较高的室内空气与温度较低的室外空气进行换气,从而加快室内温度的降低。具体而言,上述空调器所处室内环境的第一室内温度可指代空调器在进入制冷模式时刻时所采集到的室内温度,上述空调器所处室外环境的第一室外温度可指代空调器在进入制冷模式时刻时所采集到的室外温度,此外,上述空调器所处室内环境的第一室内温度及上述空调器所处室外环境的第一室外温度还可指代接收到用户发送的换气指令时刻时所采集到的温度,例如在空调器所处的室内环境中的用户对当前空调器的制冷效果不满意时,可向空调器发送换气指令,以控制空调器执行换气操作,本实施例对此不作限制,此外,上述空调器的第一设定温度指代采集上述第一室内温度及第一室外温度时空调器所设定的温度。
应当理解地,由于本申请中空调器的室内侧机壳处设有多个通孔,在设有多个通孔处的机壳部位内侧对应装置有导风叶及步进电机,因此当空调器所处室外环境的第一室外温度小于空调器所处室内环境的第一室内温度时,可基于步进电机驱动导风叶开启某一特定开度,以将室外空气通过上述风道排出至室外,从而加快室内降温。
此外,值得注意的是,由于在将室内空气通过上述风道排出至室外时,室内冷量会损失,从而可能会造成室内温度小幅度升高,因此本实施例在基于第一室内温度及第一室外温度控制空调器进行换气逻辑程序之前,还需基于第一设定温度确定当前是否开始执行换气逻辑程序,例如当第一室内温度小于第一设定温度时,表明当前室内温度已达到用户所要求的制冷温度,则为了避免制冷量损失,无需再根据第一室内温度及第一室外温度控制空调器进行换气逻辑程序,而当第一室内温度大于第一设定温度时,表明当前室内温度还未达到用户所要求的制冷温度,则为了加快室内降温,可根据第一室内温度及第一室外温度控制空调器进行换气逻辑程序,以在空调器所处室外环境的第一室外温度小于空调器所处室内环境的第一室内温度时,对温度较高的室内空气与温度较低的室外空气进行换气,从而加快室内温度的降低。此外,在另一实施例中,还可增大室外风机的转速,例如图4所示的空调器所处室内高温空气的风流向示意图,通过增大轴流风轮的转速,进而增大上述轴流风轮的负压作用,从而实现将空调器所处室内的高温空气快速抽出室外,达到快速降温的目的。
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,通过在检测到空调器处于制冷模式时,获取空调器所处室内环境的第一室内温度、空调器所处室外环境的第一室外温度及空调器的第一设定温度;根据第一室内温度、第一室外温度及第一设定温度,对空调器的导风叶开度进行调整,由此相比于现有技术中仅仅利用空调制冷系统降温,本申请通过调控空调器的导风叶开度来调控室外空气与室内空气的换气,进而加速室内温度的温降速度,从而提高人体舒适度。
进一步地,基于本申请空调器的电控冷却方法的第一实施例,提出本申请空调器的电控冷却方法第二实施例。
参照图6,图6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,所述根据所述第一室内温度、所述第一室外温度及所述第一设定温度,对空调器的导风叶开度进行调整的步骤包括:
步骤S201:判断所述第一室内温度是否大于所述第一设定温度;
步骤S202:若所述第一室内温度大于所述第一设定温度,则根据所述第一室内温度及所述第一室外温度,对空调器的导风叶开度进行调整。
本实施例中,容易理解地,由于在利用轴流风轮驱动空调器所处室内的空气从上述多个通孔进入空调器 内部,再从室外侧出风口吹出时,室内冷量会损失,从而可能会造成室内温度小幅度升高,因此本实施例在基于第一室内温度及第一室外温度控制空调器进行换气逻辑程序之前,还需基于第一设定温度确定当前是否开始执行换气逻辑程序,例如当第一室内温度小于第一设定温度时,表明当前室内温度已达到用户所要求的制冷温度,则为了避免制冷量损失,无需再根据第一室内温度及第一室外温度控制空调器进行换气逻辑程序,而当第一室内温度大于第一设定温度时,表明当前室内温度还未达到用户所要求的制冷温度,则为了加快室内降温,可根据第一室内温度及第一室外温度控制空调器进行换气逻辑程序,以在空调器所处室外环境的第一室外温度小于空调器所处室内环境的第一室内温度时,对温度较高的室内空气与温度较低的室外空气进行换气,从而加快室内温度的降低。
具体地,该步骤中,在第一室内温度大于第一设定温度时,判断当前第一室内温度是否大于第一室外温度,若第一室内温度大于第一室外温度,则表明当前室外温度低于室内温度,则由于本申请中空调器的室内侧机壳处设有多个通孔,在设有多个通孔处的机壳部位内侧对应装置有导风叶及步进电机,具体地,上述通孔为与空调器内部的风道连通的进风口,导风叶靠近所述进风口设置在所述风道内,因此本申请中室内空气与室外空气可通过上述通孔、风道及导风叶等进行换气。
具体而言,在实际应用场景中,为了避免室内冷量的损失,一般情况下,上述空调器的导风叶开度为零,即呈闭合状态,从而避免室内空气从上述风管中流出,即本实施例中上述导风叶开度决定着室内空气的换气量,因此本实施例中,为了提高室内温度的温降控制的灵活性,可实时基于对空调器的导风叶开度进行调整,从而灵活调控室内空气与室外空气的换气量,进而灵活调控室内温度的温降速度。
此外,应当理解地,在实际应用中,在室内温度还未达到设定温度时,室内温度可能会低于室外温度,即无需再将室内温度与室外温度进行换气,因此为了避免此种情况下,空调器的导风叶开启时造成室内冷量损失或室内温度升高而影响用户舒适度,本实施例中给出上述若所述第一室内温度大于所述第一设定温度,则根据所述第一室内温度及所述第一室外温度,对空调器的导风叶开度进行调整的具体实施方案:
若所述第一室内温度大于所述第一设定温度,则判断所述第一室内温度是否小于所述第一室外温度;
若所述第一室内温度小于所述第一室外温度,则控制空调器的导风叶关闭;以及,
若所述第一室内温度大于所述第一室外温度,则根据所述第一室外温度及所述第一设定温度对空调器的导风叶开度进行调整。
即在室内温度还未达到设定温度时,判断室内空气温度与室外空气温度之间的高低,即在第一室内温度小于第一室外温度时,则表明当前无需对室内空气与室外空气进行换气,因此即可控制空调器的导风叶关闭,以避免室内空气从上述风管中流出,造成室内冷量损失,此外需要说明的是,本实施例中用户可根据实际情况开启换气功能,即控制空调器的导风叶开启,例如当空调器所处室内环境的空气中存在异味时,则可开启换气功能,以通过开启的导风叶进行换气,因此在根据第一室内温度及第一室外温度控制空调器进行换气逻辑程序之前,当前空调器的导风叶可能存在以某一特定开度开启状态,因此本实施例中,在第一室内温度小于第一室外温度时,即表明当前无需对室内空气与室外空气进行换气时,检测当前导风叶的状态,若导风叶的状态为关闭状态,则维持当前导风叶继续关闭,若导风叶的状态为开启状态,则控制空调器的导风叶关闭。
具体地,上述导风叶开度大小决定着室内空气的换气量大小,在一些应用场景中,室内温度与室外温差可能会相差较大,则可控制导风叶开启较大开度,以加快室内温度降低速度,而当室内温度与室外温差不大时,且基于室外温度与设定温度之间的温差,来确定导风叶开度大小,以保证在室内冷量损失最小的情况下,降低室内温度,具体地,本实施例中给出一种上述若所述第一室内温度大于所述第一室外温度,则根据所述第一室外温度及所述第一设定温度对空调器的导风叶开度进行调整的具体实施方案:若所述第一室内温度大于所述第一室外温度,则判断所述第一室外温度是否大于所述第一设定温度;若所述第一室外温度大于所述第一设定温度,则控制空调器的导风叶开度调整为第一预设开度。
该步骤中,上述第一预设开度为预先设定的某一特定开度,可选地,本实施例中上述第一预设开度为上述空调器的导风叶所允许开启的最大开度。
具体地,本实施例中,在第一室内温度大于第一室外温度时,比较第一室外温度与设定温度的大小,若第一室外温度大于第一设定温度,则表明当前制冷系统冷量输出很少,则可控制空调器的导风叶开度为 最大开度,加大室内空气与室外空气之间的换气量,从而加快室外空气对室内温度的降低。
应当理解地,在控制空调器的导风叶开度为最大开度时,室内空气与室外空气之间的换气量最大,则在室外低温空气的影响下,室内温度会极速降低,从而渐渐接近于室外空气温度,同时由于空调器在制冷模式时会不断输出冷量,因此若空调器的导风叶继续以最大开度开启,则会造成室内制冷量的损失,从而室内温度会逐渐回温升高,进而影响用户舒适度,因此本实施例中,为了避免后续制冷量损失而造成室内回温,上述若所述第一室外温度大于所述第一设定温度,则控制空调器的导风叶开度调整为第一预设开度的步骤之后,还包括:
获取空调器以所述第一预设开度运行时空调器所处室内环境的第二室内温度、空调器所处室外环境的第二室外温度;
若所述第二室内温度大于所述第二室外温度,则获取间隔预设时间后空调器所处室内环境的第三室内温度;
根据所述第二室内温度及所述第三室内温度,对空调器的导风叶开度进行调整。
该步骤中,在控制空调器的导风叶开度调整为第一预设开度后,先获取空调器以第一预设开度运行时空调器所处室内环境的第二室内温度、空调器所处室外环境的第二室外温度,以判断当前室外空气携带的冷量是否可对室内空气进行降温,具体地,判断第二室内温度是否小于第二室外温度,若第二室内温度小于第二室外温度,则表明当前室外空气携带的冷量不可对室内空气进行降温,则为了避免室内空调器的制冷量损失,则可控制空调器的导风叶关闭,此外,当第二室内温度大于第二室外温度时,则表明当前室外空气携带的冷量可对室内空气进行降温,此时由于空调器在制冷模式时会不断输出冷量,因此在室外空气对室内空气进行降温的同时,空调器也在对室内空气进行降温,室内空气会逐渐低于室外空气,此时若空调器的导风叶继续以最大开度开启,则会造成室内制冷量的损失,从而室内温度会逐渐回温升高,进而影响用户舒适度,因此本实施例中,在第二室内温度大于第二室外温度,则获取间隔预设时间后空调器所处室内环境的第三室内温度,以判断当前室外空气对室内空气的温降作用,可以理解地,在空调器的制冷量不变的情况下,当第三室内温度越小,则表明当前室外空气的室内空气的温降作用比较大,此时可继续维持当前开度,以利用室外空气对室内空气进行降温,而当第三室内温度与第二温度之间相差不大时,则表明当前室外空气对室内空气的温降作用不大,则若继续维持当前开度,则会造成室内冷量损失,从而造成室内温度回温,进而影响用户舒适度,因此本实施例中为了解决上述技术问题,给出上述根据所述第二室内温度及所述第三室内温度,对空调器的导风叶开度进行调整的具体实施方案:获取所述第二室内温度及所述第三室内温度之间的温度差;
若所述温度差小于预设温度差,则减小空调器的导风叶开度。
即计算出第二室内温度与第三室内温度之间的温度差,由于确定室外空气对室内空气的温降作用大小,即在温度差小于预设温度差时,表明室外空气的引入,对室内侧的温降作用较小,则为了避免由于空调器的导风叶开启而导致室内冷量损失,而导致室内侧温度的回温,本实施例可减小空调器的导风叶的开度,以减少空调器产生的冷量减少,通过主要利用空调器的冷量对室内空气进行冷却,来加快室内温度的温降速度。
此外,在另一实施例中,当温度差大于预设温度差时,表明室外空气的引入,对室内侧的温降作用较大,则此时可继续维持当前开度,以利用室外空气加快室内空气的温降。
此外,在另一应用场景中,设定温度高于室外温度,则表明当前室内温度的温降主要取决于室外环境,因此即使在空调器不制冷的情况下,室内温度也呈下降趋势,因此为了减少空调器的耗电量,可控制空调器的导风叶开启某一特定开度,以利用室外空气对室内进行降温,此外,还可对空调器进行限频,以减少空调器的耗电量,具体地,本实施例中,上述判断所述第一室外温度是否大于所述第一设定温度的步骤之后,还包括:
若所述第一室外温度小于或等于所述第一设定温度,则获取所述第一室外温度与所述第一设定温度之间的温度差;
根据所述温度差确定目标开度,并控制空调器的导风叶开度调整为所述目标开度。
该步骤中,可选地,上述温度差与目标开度之间存在一预设映射关系,即在获取第一室外温度与第一设定温度之间的温度差之后,根据该预设隐射关系获取目标开度,此外,本实施例中为了加快空调器的动 作执行速度,还可确定温度差处于的温度差区间,以通过该温度差区间预设匹配的开度来获取温度差对应的目标开度,本实施例对此不作限制。
应当理解地,在设定温度高于室外温度,则表明当前室内温度的温降主要取决于室外环境,因此本实施例中根据室外温度与设定温度之间的温差大小决定空调器的导风叶的开度,例如当室外温度与设定温度之间的温差大小为5度时,可控制空调器的导风叶的开度调整为第一开度,当室外温度与设定温度之间的温差大小为2度时,可控制空调器的导风叶的开度调整为第二开度,其中第二开度小于第一开度,即随着第一室外温度与第一设定温度之间的温度差的降低而减少空调器的导风叶的开度。
此外,应当理解地,在室外温度低于室内温度及设定温度时,此时室外空气可进入室内对室内进行降温,同时由于即使在空调器不制冷的情况下,室内温度也呈下降趋势,因此为了减少空调器的耗电量,在调控空调器的导风叶开度之后,降低空调器的压缩机频率,进减少空调器的耗电量。
所述根据所述温度差确定目标开度,并控制空调器的导风叶开度调整为所述目标开度的步骤之后,还包括:
获取空调器以所述目标开度运行时空调器所处室内环境的实时室内温度,并根据所述实时室内温度确定室内温度变化速度;
若检测到所述室内温度变化速度维持不变,则降低空调器的压缩机的运行频率。
具体而言,上述室内温度变化速度指代单位时间内室内温度的下降速度,该步骤中,容易理解地,在室内温度变化速度维持不变时,表明当前室外空气携带的制冷量以足够对室内空气进行降温,则本实施例中可对空调器进行限频,以在室内温度呈下降趋势时,减少空调器的耗电量。
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。
本实施例中,通过判断第一室内温度是否大于所述第一设定温度,若第一室内温度大于第一设定温度,则根据第一室内温度及第一室外温度,对空调器的导风叶开度进行调整,由此保证室内冷量损失不大的情况下加快室内降温。
进一步地,基于本申请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三实施例。参照图7,图7为本申请空调器的控制方法第三实施例的流程示意图;
所述空调器的控制方法第三实施例与所述空调器的控制方法第一实施例的区别在于,所述在检测到空调器处于制冷模式的步骤之后,还包括:
步骤S30:若接收到换气指令,则控制空调器的导风叶开度调整为第二预设开度。
具体而言,上述第二预设开度可为用户预先设定的某一特定开度,还可为换气指令中携带的某一特定开度,本实施例对此不作限制。

本实施例中,所述空调器的控制装置为虚拟装置,存储于图1所示的空调器的存储器1005中,以实现 空调器的控制程序的所有功能:用于在检测到空调器处于制冷模式时,获取空调器所处室内环境的第一室内温度、空调器所处室外环境的第一室外温度及空调器的第一设定温度;用于根据所述第一室内温度、所述第一室外温度及所述第一设定温度,对空调器的导风叶开度进行调整。
具体地,参照图8,所述空调器的控制装置包括:

在具体实现中,在室外机区域设置蓄水器,在蓄水器(蓄水器的水来源于室内蒸发器的冷凝水)布置过冷管,制冷剂在冷凝器换热后,再经过过冷管,温度进一步降低,从而提高制冷量。但是在室外温度较高,冷凝器热负荷较大的情况下,蓄水器水温很快会上升到一个比较高的值,此时,过冷管的效果将会大大减小,造成制冷量的不足。本方案将蓄水器的水通过水泵泵入室内的蓄冷模块,水在蓄冷模块温度降低后,再进入蓄水器,保持蓄水器温度保持在较低的值,保证过冷管的有效作用,从而提高高温制冷量。蓄水器设置有溢流孔,在蓄水器水位达到一定高度的情况下,冷凝水可以通过溢流孔排出室外,保证冷凝水不会进入机器内部,保证整机可靠性。

在具体实现中,图12为一实施例的开启水泵时的冷量循环示意图,制冷剂可在循环回路中按照图12中的实线循环路线进行循环,水可在循环回路中按照图12中的虚线循环路线进行循环。此时,制冷剂从压缩机1流出,流入冷凝器2,在冷凝器2中进行一次换热后,进入过冷管10,制冷剂在过冷管10中继续换热,在空调器开启水泵8后,室内储能换热器7释放的冷量可以通过水泵8进入蓄水器9,由蓄水器9根据室内储能换热器7释放的冷量对过冷管10进行冷却,进而对过冷管10中的制冷剂进一步换热,最后,换热后的制冷剂通过第一截止阀4以及第二截止阀5进入蒸发器6进行制冷,以达到提高高温下的制冷量的目的。
