Description

空调及其制冷控制方法 技术领域
本发明涉及空气调节技术领域，特别涉及一种空调及其制冷控制方法。
背景技术
随着生活水平的提高，空调已经成为家庭和商用场合必不可少的电器产品。空调通常具有丰富的调节选项，以供用户调节。例如，用户可以对空调的目标温度、风速、导风板的导风方向(也即上下导风角度)和摆叶的导风方向进行调节。
但是，很多用户在使用空调时仅仅设定目标温度，甚少关注或主动使用其他调节功能。还有些用户热衷于对空调的各种调节功能进行组合调节以及频繁地调节，但因缺少专业知识，反而难以获得最好的制冷效果。
发明内容
本发明的目的在于至少解决现有技术存在的上述缺陷之一，提供一种具有智慧节能控制模式的空调及其制冷控制方法。
本发明的进一步的目的是使空调既要加快制冷速度，又要满足用户的舒适性需求。
一方面，本发明提供了一种空调的制冷控制方法，所述空调包括多个用于引导出风口的上下出风角度的导风板，所述制冷控制方法包括如下步骤：
接收到智能控温模式的开启指令后，进入制冷初期阶段，以第一目标温度为制冷目标温度，且使各所述导风板进行最大范围往复摆风；
当满足第一切换条件时，使所述空调从所述制冷初期阶段切换至制冷中期阶段，使制冷目标温度高于所述第一目标温度，且使各所述导风板转动至上导风角度；
当满足第二切换条件时，使所述空调从所述制冷中期阶段切换至稳定运行阶段，使制冷目标温度高于所述第一目标温度并关闭部分导风板。
可选地，在所述稳定运行阶段，使未被关闭的导风板保持在所述上导风角度。
可选地，所述稳定运行阶段的制冷目标温度大于或等于所述制冷中期阶段的制冷目标温度。
可选地，所述空调的风机在所述制冷初期阶段时的转速大于在所述制冷中期阶段时的转速。
可选地，在所述稳定运行阶段，根据室内环境温度来调节所述空调的风机转速。
可选地，所述第一切换条件为：所述制冷初期阶段运行时长达到第一预设时长或室内环境温度小于等于第一温度阈值，所述第一温度阈值大于所述制冷中期阶段的制冷目标温度。
可选地，所述第二切换条件为：所述制冷中期阶段运行时长达到第二预设时长或室内环境温度与所述制冷中期阶段的制冷目标温度的差值小于或等于预设差值。
可选地，所述第一预设时长的取值范围为1min至5min；所述第二预设时长的取值范围为18min至22min。
另一方面，本发明还提供了一种空调，其包括：
壳体，其开设有出风口；
多个导风板，每个所述导风板可转动地安装于所述壳体，以用于引导所述出风口的上下出风角度；和
控制器，所述控制器包括处理器和存储器，所述存储器存储有计算机程序，所述计算机程序被所述处理器执行时用于实现根据以上任一项所述的制冷控制方法。
可选地，所述多个导风板沿所述壳体的横向方向分为多组，每组包括上下两个导风板。
本发明的空调的制冷控制方法中，空调具有智能控温模式，将智能控温模式分成多个运行阶段，不同的运行阶段发挥不同作用。在制冷初期阶段进行快速制冷，使导风板最大范围往复摆风，使室内环境温度快速下降。在制冷中期阶段，适当调高制冷目标温度，以减少压缩机功率，使导风板保持在上导风角度，以避免冷风直吹人体。在稳定运行阶段，关闭部分导风板，使得空调的风量进一步降低，使室内环境保持在低风状态，使人体感觉更加舒适。
本发明既实现了室内环境的快速降温，又能满足用户的舒适性需求，而且还节约了空调能耗，实现了节能减排的目标。此外，本发明的制冷控制方法实现了智能控温和自动调节，免去了用户反复调节各项参数的麻烦，增强 了用户的智能化体验。
进一步地，本发明的空调的制冷控制方法中，对不同的运行阶段设计了不同的风机转速档位，以便与各运行阶段的制冷目标相匹配，达到最优的制冷效果。

本发明实施例的空调包括多个用于引导出风口12的上下出风角度的导风板50。例如图3所示，可使多个导风板50沿所述壳体10的横向方向分为多组(图示为两组)，每组包括上下两个导风板50。每个导风板50可绕水平横向轴线转动地安装于壳体10。每个导风板50各自匹配有电机(未图示)，每个电机各自独立地接受控制器800的控制。如此，使得空调对于上下出风角度的调节更加细化。
图1是根据本发明一个实施例的空调的制冷控制方法的示意图；图2是本发明一个实施例的空调的示意性框图；图3是根据本发明一个实施例的空调的结构示意图；图4是图3所示空调在出风区域被剖开时的示意性侧视放大图；图5是图3所示空调在左侧导风板被关闭，右侧导风板处于上导风角度时的示意图；图6是图5所示空调在出风区域被剖开时的示意性侧视放大图。
如图1至图6所示，本发明实施例的空调的制冷控制方法包括：
步骤S102：接收到智能控温模式的开启指令。
具体地，用户希望空调运行智能控温模式时，可对遥控器、线控器、空调主机的控制面板或者其他与空调进行无线连接的智能终端设备进行相应操作，使其向空调的控制器800发出智能控温模式的开启指令。
步骤S104：运行制冷初期阶段。
即，当空调的控制器800接收到智能控温模式的开启指令后，控制空调进入制冷初期阶段，在制冷初期阶段，以预设的第一目标温度为制冷目标温 度。并且，使各导风板50进行最大范围往复摆风。
该步骤中，第一目标温度是低于一般用户习惯设定的制冷目标温度。例如，一般用户习惯将制冷目标温度设定在25℃至29℃之间，故可将第一目标温度设置在18℃至23℃之间，例如设置为22℃。制冷初期阶段将制冷目标温度设置地较低，以便促使压缩机以更高频率运行，使得空调的制冷量更大，使室内温度更快速地下降，以使室内环境尽快脱离炎热的状态。使各导风板50进行最大范围往复摆风，以便冷风更大范围地扩散，加快制冷速度。进一步地，还可使摆叶60进行最大范围往复摆风。
步骤S106：判断是否满足预设的第一切换条件。若是，执行步骤S108；若否，返回执行步骤S104。
步骤S108：运行制冷中期阶段。
也即，当满足预设的第一切换条件时，使空调从制冷初期阶段切换至制冷中期阶段。制冷中期阶段的制冷目标温度高于第一目标温度，且使各导风板50转动至上导风角度，以便将出风气流朝上引导，避免冷风吹人。
经历了制冷初期阶段，室内环境温度已经有了显著降低，如果继续使空调快速、大功率地制冷运行，压缩机功耗较大，空调耗电量太大。因此，当满足预设的第一切换条件时，便及时使空调切换运行制冷中期阶段，调高制冷目标温度，使压缩机降频。例如，在一种可选的方案中，可将第一目标温度设置为22℃，将制冷中期阶段的制冷目标温度设置为24℃。
在一些实施例中，整个制冷中期阶段的制冷目标温度为常数。在另一些实施例中，也可使制冷中期阶段的制冷目标温度为变量，使其以预设函数呈递减趋势。
步骤S110：判断是否满足预设的第二切换条件。若是，执行步骤S112；若否，返回执行步骤S108。
步骤S112：运行稳定运行阶段。
也即，当满足预设的第二切换条件时，判断室内环境已经达到或基本达到了一般用户所需要的舒适温度范围，便使空调从制冷中期阶段切换至预设的稳定运行阶段。在该稳定运行阶段，使制冷目标温度高于第一目标温度并关闭部分导风板50。此处的关闭某个导风板50，指的是将该导风板50转动至关闭出风口12的位置，参考图5左侧的导风板50。例如，可关闭一组导风板50。如此使得空调的风量进一步降低，使室内环境保持在低风状态，使 人体感觉更加舒适。稳定运行阶段的制冷目标温度大于或等于制冷中期阶段的制冷目标温度，以使压缩机保持在低频率运行。
此外，在稳定运行阶段，可使未被关闭的导风板50保持在上导风角度，如图5，以便保持在不吹人的角度。
总之，本发明实施例的空调的制冷控制方法中，空调具有智能控温模式，将智能控温模式分成多个运行阶段，不同的运行阶段发挥不同作用。在制冷初期阶段进行快速制冷，使导风板50以最大范围往复摆风，使室内环境温度快速下降。在制冷中期阶段，适当调高制冷目标温度，以减少压缩机功率，使导风板50保持在上导风角度，以避免冷风直吹人体。在稳定运行阶段，关闭部分导风板50，使得空调的风量进一步降低，使室内环境保持在低风状态，使人体感觉更加舒适。
本发明实施例既实现了室内环境的快速降温，又能满足用户的舒适性需求，而且还节约了空调的能耗，实现了节能减排的目标。此外，本发明实施例的制冷控制方法实现了智能控温和自动调节，免去了用户反复调节各项参数的麻烦，增强了用户的智能化体验。
进一步地，本发明的空调的制冷控制方法中，对不同的运行阶段设计了不同的风机转速档位，以便与各运行阶段各自的制冷目标相匹配，达到最优的制冷效果。风机30用于促使室内空气进入壳体10，使气流与换热器完成换热后形成冷风或热风，然后经出风口12向外吹出。
具体地，在一些实施例中，使空调的风机30在制冷初期阶段时的转速大于在制冷中期阶段时的转速。具体地，在制冷初期阶段，可使风机30以最大转速(或者称为最强风档)运行。在制冷中期阶段，可使风机30以中间转速(或者称为中间风档)运行。
在一些实施例中，在稳定运行阶段，根据室内环境温度来调节空调的风机转速。也即，室内环境温度处于较高档次时，采用较高的风机转速，以适当加快制冷速度。当室内环境温度处于较低档次时，采用较低的风机转速。空调可设置有温度检测模块40，以用于检测室内环境温度。温度检测模块40可为温度传感器。
在一些实施例中，前述的第一切换条件为：制冷初期阶段运行时长达到第一预设时长或室内环境温度小于等于第一温度阈值，第一温度阈值大于制冷中期阶段的制冷目标温度。也即，两种情况满足之一即可判定为满足了第 一切换条件。
第二切换条件为：制冷中期阶段运行时长达到第二预设时长或室内环境温度与制冷中期阶段的制冷目标温度的差值小于或等于预设差值。
例如，在一个优选实施例中，可使第一目标温度设置为22℃，使制冷中期阶段的制冷目标温度设置为24℃，使第一温度阈值设置为26℃。使预设差值为1℃。当室内环境温度小于等于23°时，其与制冷目标温度的差值即小于等于1℃，满足了第二切换条件。
第一预设时长的取值范围为1min至5min，例如3min。第二预设时长的取值范围为18min至22min，例如20min。使第一预设时长偏短，以避免压缩机长期高频运行，导致室内温度过冷、压缩机耗能过高。
本发明另一方面提供了一种空调。本发明对空调的形式不作任何限定，空调可为壁挂机、柜机、窗机、天井机或其他各种形式的空调。
如图3至图6所示，本发明实施例的空调一般性地可包括壳体10、多个导风板50以及控制器800。
壳体10开设有出风口12，以用于吹出冷风气流。每个导风板50可转动地安装于壳体10，以用于引导出风口12的上下出风角度。例如图3所示，可使多个导风板50沿壳体10的横向方向分为多组，每组包括上下两个导风板50。例如图3所示，分为两组，共四个导风板50。例如图4所示，可使上侧的导风板50和下侧的导风板50都进行摆风，以扩大摆风角度范围。也可如图5和图6所示，关闭左侧的一组导风板50，使右侧导风板50处于上导风角度。当然，还可通过对各个导风板50的导风角度进行组合，以获取更多的导风模式，在此不再一一赘述。
控制器800包括处理器810和存储器820，存储器820存储有计算机程序821，计算机程序821被处理器810执行时用于实现本发明任一实施例的空调的制冷控制方法。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
