本公开的一些实施例提供一种空调器，图1为本公开的一些实施例提供的一种空调器的结构图。如图1所示，空调器1包括室内机100和室外机200。
示例性地，如图1所示，室内机100包括第一控制器10，室外机200包括第二控制器20和压缩机30。其中，第二控制器20分别与第一控制器10和压缩机30耦接。
在一些示例中，室内机100还包括室内换热器101；室外机200还包括室外换热器201、膨胀阀202和四通阀203。其中，压缩机30、室外换热器201、膨胀阀202和室内换热器101之间通过管路连接，形成冷媒回路，冷媒在冷媒回路中循环流动，并通过室内换热器101和室外换热器201分别与空气进行交换，以实现空调器1的制冷和制热功能。
在一些实施例中，压缩机30被配置为压缩冷媒，以使得低压冷媒受压缩形成高压冷媒。膨胀阀202，例如可以为电子阀，连接于室内换热器101与室外换热器201之间，膨胀阀202的开度是可调节，用于控制流经膨胀阀202的冷媒的流量和压力，从而用于调节流通于室外换热器201和室内换热器101之间的冷媒流量。室内换热器101和室外换热器201之间流通的冷媒的流量和压力将影响其各自的换热性能。在一些示例中，膨胀阀202也可以设置在室内机100中。四通阀203连接于冷媒回路内，四通阀203被配置为切换冷媒在冷媒回路中的流向以使空调器1对室内机100所处环境(以下称为室内环境)执行制冷或制热。
示例性地，空调器1的工作模式可以包括制热模式和制冷模式。其中，当满足制热条件时，空调器1工作在制热模式。当空调器1工作在制热模式时，室内换热器101可以用作冷凝器，室外换热器201可以用作蒸发器，空调器1实现对室内环境进行制热。例如，制热条件可以空调器1的运行温度高于第一预设温度。当满足制冷条件时，空调器1工作在制冷模式。当空调器1工作在制冷模式时，室内换热器101可以用作蒸发器，室外换热器201可以用作冷凝器时，空调器1实现对室内环境进行制冷。例如，制冷条件可以包括空调器1的运行温度低于第二预设温度。在一些示例中，第一预设温度大于第二预设温度。
图2为本公开的一些实施例提供的一种室内机100的结构图。如图2所示，室内机100还包括机壳102、出风导风板103以及出风口104。其中，出风导风板103与机壳102连接，且出风导风板103设于出风口104处，以打开或关闭出风口104。
在室内环境的温度较高时，空调器1通常工作在制冷模式，以降低室内环境的温度。为了实现快速降温，压缩机30通常会以一个较高的运行频率运行，此时，室内环境中温度较高的空气进入机壳102的内部后，经过与室内换热器101中的冷媒进行换热后，得到温度较低的空气，该温度较低的空气流向出风口104，并从出风口104吹到室内，实现对室内环境的降温。
示例性地，当空调器1工作在制冷模式时，若室内环境的温度和相对湿度较高，室内环境的露点温度也会较高。这种情况下，若压缩机30以一个较高的运行频率运行时，在室内机100的出风口104所吹出空气的温度较低，即室内机100的出风温度较低。这样会导致室内环境的露点温度与室内机100的出风温度之间的温差较大，从而使室内环境中的水蒸气容易凝结在室内机100的出风口104或者出风导风板103上产生水珠，导致室内机100的出风口104存在吹出水珠的隐患，这种现象称为凝露现象。
也就是说，当空调器1工作在制冷模式，且室内环境的温度和相对湿度较高时，若压缩机30以一个较高的运行频率运行，室内机100的出风口104、外壳102以及出风导风板103等处可能会发生凝露现象。凝露现象会破坏室内环境，影响用户的使用体验。
在一些实施例中，可以通过限制(例如降低)压缩机30的运行频率来避免凝露现象的产生，但是，压缩机30的运行频率影响空调器1的制冷效果，如果将压缩机30的运行频率限制的过小可能会影响空调器1的制冷效果，而如果将压缩机30的运行频率限制的不够，可能不能完全避免凝露现象的产生。因此，如何控制压缩机30以一个较佳的目标运行频率运行，既可以保证空调器1达到快速降温的同时，又可以保证空调器1不会出现凝露现象成为亟待解决的问题。相关技术中，可以通过采集空调器1的盘管温度来计算压缩机的运行频率，而空调器1的盘管温度的变化范围一般较小(如8℃-20℃)，因此要计算得到压缩机30的目标运行频率较为困难，且获取到的目标运行频率也不够准确。
本公开的一些实施例提供的空调器1，能够以简单有效的方式来获取到压缩机30的目标运行频率，实现空调器1在保证制冷效果的同时，避免凝露现象的产生。
如图1所示，第二控制器20被配置为：控制压缩机30以第一运行频率运行，以使室内机100所处环境的温度降低。
当空调器1工作在制冷模式时，第二控制器20会控制压缩机30以第一运行频率运行，实现对室内环境的制冷。本公开一些实施例以空调器1工作在制冷模式为例进行示例性说明。
示例性地，压缩机30的第一运行频率可以为第二控制器20中预设的运行频率。第一运行频率与室内环境的温度情况有关，例如第一运行频率与室内环境的温度变化值和/或温度变化速率有关。也就是说，第一运行频率可以随着室内环境的温度变化而动态调整。空调器1工作在制冷过程中，第二控制器20可以根据室内环境的温度变化情况来控制压缩机30的运行频率。在一些示例中，压缩机30的第一运行频率越大，空调器1的制冷效果越好。
第一控制器10被配置为：获取室内机100所处环境的当前温度信息和当前相对湿度信息。
在一些实施例中，如图3所示，室内机100还包括检测装置40，检测装置40与第一控制器10耦接，且被配置为：检测室内机100所处环境的当前温度信息和当前相对湿度信息，并向第一控制器10发送当前温度信息和当前相对湿度信息。第一控制器10被配置为：接收检测装置40发送的当前温度信息和当前相对湿度信息。
由上述实施例可知，空调器1产生凝露现象与室内环境的露点温度相关，当压缩机30以第一运行频率运行时，室内机100的出风口104吹出的空气具有一个出风温度，此时，当室内环境的露点温度越高时，与出风口104的出风温度之间的温差越大，因而空调器1也就越容易产生凝露现象。而室内环境的露点温度与室内环境的温度及相对湿度相关，因此，本公开一些实施例对室内环境的当前温度和当前相对湿度进行监控，并根据当前温度和当前相对湿度来获取压缩机30的较佳的运行频率，以保证空调器1达到快速降温的同时，又能够保证空调器1不会出现凝露现象。
示例性地，参照图4，检测装置40可以包括温度检测装置41和湿度检测装置42。 温度检测装置41和湿度检测装置42分别与第一控制器10耦接。其中，温度检测装置41用于对室内环境的当前温度进行检测，获取当前温度信息，并将当前温度信息发送给第一控制器10。湿度检测装置42用于对室内环境的当前相对湿度进行检测，获取当前相对湿度信息，并将当前相对湿度信息发送给第一控制器10。
示例性地，第一控制器10与第二控制器20耦接，第一控制器10可以将获取到的当前温度信息和当前相对湿度信息发送给第二控制器20。
在一些实施例中，温度检测装置41可以为温度传感器，湿度检测装置42可以为湿度传感器。温度传感器和湿度传感器均处于室内环境，且分别对室内环境的温度变化和相对湿度的变化的反应较为灵敏，因此，可以确保所检测到的当前温度信息和当前相对湿度信息的准确性较高。或者，检测装置40也可以包括温湿度传感器，用于对室内环境的温度和相对湿度进行检测，本公开一些实施例对此不作限制。
第二控制器20还被配置为：接收当前温度信息和当前相对湿度信息，根据当前温度信息、当前相对湿度信息以及预设对应关系，确定当前温度信息和当前相对湿度信息在预设对应关系中对应的压缩机30的第二运行频率。其中，预设对应关系包括多个温度信息和多个相对湿度信息与压缩机30的多个运行频率的对应关系。
示例性地，预设对应关系中的压缩机30的多个运行频率中的一个运行频率可以为多个温度信息中的某一温度信息和多个相对湿度信息中的某一相对湿度信息下，压缩机30的最大允许运行频率。示例性地，压缩机30的最大允许运行频率可以为在某一温度和某一相对湿度下，空调器1产生凝露现象的一个临界运行频率。也就是说，在该温度和相对湿度下，若压缩机30的运行频率大于该最大允许运行频率，空调器1容易产生凝露现象，而当压缩机30的运行频率小于或等于该最大允许运行频率时，空调器1不容易会产生凝露现象。
但是，在该温度和相对湿度下，若压缩机30的运行频率小于该最大允许运行频率时，虽然空调器1不容易产生凝露现象，但是也不能达到较佳的制冷效果。而当压缩机30的运行频率为该最大允许运行频率时，空调器1既能达到佳的制冷效果，也不容易产生凝露现象。
因此，在预设对应关系中，压缩机30的最大允许运行频率即为实现空调器1的制冷效果和防凝露效果的一个折中的运行频率。
示例性地，预设对应关系可以通过在不同温度和不同湿度下，对空调器1产生凝露现象的临界点时，压缩机30的运行频率进行测试得到。例如，对于空调器1来说，可以某一温度范围和某一湿度范围内，对每个温度和每个相对湿度之间组合时，测试在空调器1产生凝露现象的临界点，压缩机30的各运行频率，该运行频率即为压缩机30的最大允许运行频率。
在一些实施例中，参照图3，室外机200还包括存储器50，存储器50与第二控制器20耦接。其中，预设对应关系可以存储在存储器50中，第二控制器20通过存储器50对预设对应关系进行查询。在一些示例中，可以在空调器1在出厂前，将预设对应关系存储在室外机200的存储器50中。或者，预设对应关系也可以预先存储在第二控制器20中。
在一些实施例中，在预设对应关系中，多个温度信息中每个温度信息对应的温度T满足关系：25℃≤T≤35℃；多个相对湿度信息中每个相对湿度信息对应的湿度Φ满 足关系：50％≤Φ≤100％。
通常，在室内环境的温度较高时，例如在室内环境的温度大于30℃时，空调器1会进入制冷模式以降低室内环境的温度，同时考虑到舒适性，会选择室内环境的温度大于或等于25℃。并且，在室内环境的相对湿度大于或等于50％的情况下，空调器1的室内机100，尤其是室内机100的出风口104处容易发生凝露现象。因此，可以将预设对应关系中多个温度信息中每个温度信息对应的温度T设置在25℃≤T≤35℃的范围，将多个相对湿度信息中每个相对湿度信息对应的湿度Φ设置在50％≤Φ≤100％的范围，在这个范围内，空调器1容易产生凝露现象。而当室内环境的温度较低，例如小于25℃，相对湿度较小，例如小于50％时，空调器1一般不会产生凝露现象，因此，无需将预设对应关系中对应的温度T和相对湿度Φ的范围设置过大，这样可以降低预设对应关系的复杂度，提高第二控制器20的查找效率。
示例性的，不同的空调器1对应的预设对应关系可能不同。预设对应关系与空调器1中的压缩机30相关。在一些示例中，预设对应关系与压缩机30的排量大小和制冷量相关。也就是说，压缩机30的最大允许频率与压缩机30的排量大小和制冷量有关，例如，在压缩机30的制冷量一定的情况下，压缩机30的排量越大，压缩机30的最大允许频率就越小。因此，可以根据不同的压缩机30，得到不同的预设对应关系，并将该预设对应关系存储在存储器50中。
在一些示例中，预设对应关系可以为预设对应关系表的形式，比如，该预设对应关系可以为一个数据查找表。下面以预设对应关系为数据查找表为例进行示例性说明。
表1为本公开一些实施例提供的一个数据查找表的示例。如表1所示，该数据查找表中包括了多个温度和多个相对湿度，以及多个温度中每个温度T与多个相对湿度中每个相对湿度Φ组合时，分别对应的压缩机30的各最大允许运行频率H。
表1
Figure PCTCN2022126253-appb-000001
如表1所示，压缩机30的最大允许频率H1至H54分别表示在不同的温度T和不同相对湿度Φ下，压缩机30的各最大允许运行频率。
在一些实施例中，第二控制器20还配置为：若当前温度信息对应的温度T和/或当前相对湿度信息对应的相对湿度Φ越大，根据当前温度信息和当前相对湿度信息在预设对应关系中确定的压缩机30的运行频率越小。
在一些示例中，参照表1，当温度T为31℃，相对湿度为60％时，所对应的压缩机30的最大允许运行频率为H25，例如，H25的大小可以为48Hz；当温度T为31℃，相对湿度Φ为70％时，所对应的压缩机30的最大允许运行频率为H26，例如，H26的大小可以为42Hz；当温度T为31℃，相对湿度Φ分别为80％时，所对应的压缩机30的最大允许运行频率为H27，例如，H27的大小为40Hz。由此可以看出，在预设对应关系中，温度T一定的情况下，相对湿度Φ越大，压缩机30的最大允许频率就越小。
在另一些示例中，参照表1，当相对湿度Φ为70％，温度T为28℃时，所对应的压缩机30的最大允许运行频率为H40，例如，H40的大小为44Hz；当相对湿度Φ为70％，温度T为31℃时，所对应的压缩机30的最大允许运行频率为H26，例如，H26的大小为42Hz；当相对湿度Φ为70％，温度T为35℃时，对应的压缩机30的最大允许运行频率为H3，例如，H3的大小为40Hz。由此可以看出，在预设对应关系中，相对湿度Φ一定的情况下，温度T越大，压缩机30的最大允许频率就越小。
在又一些示例中，参照表1，当温度T为26℃，相对湿度Φ为70％时，所对应的压缩机30的最大允许运行频率为H48，例如，H48的大小为48Hz；当温度T为31℃，相对湿度Φ为80％时，所对应的压缩机30的最大允许运行频率为H27，例如，H48的大小为40Hz。由此可以看出，在预设对应关系中，温度T越大，且相对湿度Φ越大，其对应的压缩机30的最大允许运行频率就越小。这是因为当温度T和相对湿度Φ较高时，空调器1更容易产生凝露现象，因此需要限制压缩机30的最大允许运行频率更低一些，才能够更好的避免凝露现象的产生。
因此，在表1所示的压缩机30的最大允许运行频率H1至H54中，由于H6为最大温度T(35℃)和最大相对湿度Φ(100％)所对应的最大允许频率，因此H6为H1至H54中最小的一个最大允许运行频率。
在第二控制器20接收到室内环境的当前温度信息和当前相对湿度信息后，可以在预先存储的预设对应关系中查找当前温度信息和当前相对湿度信息所对应的压缩机30的最大允许运行频率，该最大允许运行频率例如为第二运行频率，第二运行频率可以为预设对应关系中包括的多个运行频率中的一个运行频率。
第二控制器20被配置为：确定第一运行频率是否大于第二运行频率；若确定第一运行频率大于第二运行频率，控制压缩机30以第二运行频率运行。
当第二控制器20从预设对应关系中查找到压缩机30的第二运行频率(即最大允许运行频率)后，比较第二运行频率与压缩机30的第一运行频率(即当前运行频率)的大小。若第一运行频率大于第二运行频率，表明压缩机30的当前运行频率过高，且已超出压缩机30的最大允许运行频率，因而当压缩机30以第一运行频率运行时，会导致室内机100的出风口104处的出风温度过低，容易导致凝露现象的发生，因此，第二控制器20需要限制压缩机30的当前运行频率。
示例性地，第二控制器20可以将压缩机30的第一运行频率下降到第二运行频率，以使压缩机30以第二运行频率运行。由上述实施例可知，第二运行频率为预设对应关系中，当前温度信息和当前相对湿度信息下，压缩机30的最大允许运行频率，当压缩机30以第二运行频率运行时，空调器1既可以很好地发挥制冷降温作用，又可以很大程度上避免凝露现象的产生。
在一些实施例中，第二控制器20还被配置为：若确定第一运行频率小于或等于第二运行频率，控制压缩机30以第一运行频率运行。
若第一运行频率小于或等于第二运行频率，表明压缩机30的当前运行频率(即第一运行频率)没有超过预设对应关系中的压缩机30的最大允许运行频率(即第二运行频率)，因此，当压缩机30以第一运行频率运行时，不会引起空调器1产生凝露现象，此时，第二控制器20无需对压缩机30的当前运行频率进行干涉，压缩机30可以仍继续以当前运行频率运行。这样，可以使空调器1灵活地按照当前室内环境确定是否干涉压缩机30的运行频率。
因此，本公开一些实施例提供的空调器1，根据其工作在制冷模式下时，室内环境的当前温度信息和当前相对湿度信息，通过预设对应关系，确定在当前温度信息和当前相对湿度信息下，压缩机30的最大允许运行频率，并在压缩机30的当前运行频率(即第一运行频率)大于该最大允许运行频率(即第二运行频率)时，将当前运行频率降低至最大允许运行频率。因此，本公开一些实施例可以以简单且有效的方式实现对压缩机30的运行频率的控制，以确保空调器1既发挥快速降温作用，又避免凝露现象的产生。
在一些实施例中，第二控制器20还被配置为：若根据当前温度信息、当前相对湿度信息以及预设对应关系，确定当前温度信息和当前相对湿度信息在预设对应关系中对应的结果为空，控制压缩机30以第一运行频率运行。
示例性地，在第二控制器20接收到当前温度信息和当前相对湿度信息时，可以先判断根据当前温度信息和相对湿度信息查询预设对应关系的查询结果，若查询结果不为空，按照上述一些实施例对压缩机30的当前运行频率进行处理；若查询结果为空，第二控制器20不对压缩机30的当前运行频率(第一运行频率)进行干涉，压缩机30可以继续以当前运行频率运行。
第二控制器20根据当前温度信息、当前相对湿度信息以及预设对应关系(例如数据查找表)，确定当前温度信息和当前相对湿度信息在预设对应关系中对应的结果为空，指的是：第二控制器20在预设对应关系中，未查找到与当前温度和当前相对湿度相对应的压缩机30的最大允许运行频率。
在一些示例中，第二控制器20在预设对应关系中查找到当前温度信息，但未查找到当前相对湿度信息时，无法查找到与当前温度和当前相对湿度相对应的压缩机30的最大允许运行频率。例如，参照表1提供的数据查询表，若当前温度信息对应的温度T为28℃，当前相对湿度信息对应的相对湿度Φ为30％时，由于表1的数据查询表中不包括相对湿度Φ为30％的情况，因此，第二控制器20的查询结果为空。
在另一些示例中，第二控制器20在预设对应关系中查找到当前相对湿度信息，但未查找到当前温度信息时，无法查找到与当前温度和当前相对湿度相对应的压缩机30的最大允许运行频率。例如，参照表1提供的数据查询表，若当前温度信息对应的温度T为23℃，当前相对湿度信息对应的相对湿度Φ为60％时，由于表1的数据查询表中不包括温度T为23℃的情况，因此，第二控制器20的查询结果也为空。
在又一些示例中，第二控制器20在预设对应关系中查找到当前温度信息和当前相对湿度信息，但未查找到与当前温度和当前相对湿度相对应的压缩机30的最大允许运行频率。例如，参照表1提供的数据查询表，某些温度T和相对湿度Φ所对应的压缩 机30的最大允许运行频率处为空。比如，当温度T为25℃，相对湿度Φ为50％时，所对应的压缩机30的最大允许运行频率为空，即没有相关数据信息。此时，第二控制器20的查询结果也为空。
由于当空调器工作在制冷模式时，若室内环境的当前温度和/或相对湿度较低，室内环境的露点温度与室内机100的出风口104的出风温度的温差不会太大，因而即使压缩机30的当前运行频率很高(如大于最大允许运行频率)，空调器1发生凝露现象的可能性也较小，或者不会发生凝露现象。因此，在预设对应关系中可以无需记录室内环境的较低温度和较低相对湿度的情况；或者，即使预设对应关系中记录了室内环境的较低温度和较低相对湿度的组合，也可使其对应的压缩机30的最大允许运行频率的信息保持为空(即不记录最大允许运行频率的值)。这样可以降低预设对应关系的数据量，简化预设对应关系的设计复杂度，并提高空调器1的查表效率，降低查找工作量。
在一些实施例中，第一控制器10被配置为：经过预设时间，获取变化后的室内机100所处环境的当前温度信息和当前相对湿度信息，并向第二控制器20发送变化后的当前温度信息和变化后的当前相对湿度信息。
示例性地，若第二控制器20根据室内环境的当前温度信息和当前相对湿度信息，在预设对应关系中查找到了压缩机30的最大允许运行频率，将这种情况称为空调器1进入防凝露模式。在空调器1进入防凝露模式一段时间后，室内环境的当前温度信息和当前相对湿度信息会进行发生变化，例如，室内环境的当前温度和/或相对湿度会降低，变化后的当前温度信息和变化后的当前相对湿度信息可能在预设对应关系中无法查找到压缩机30的最大允许运行频率，此时，表明变化后的当前温度和当前湿度可能不会导致或者不容易导致空调器1发生凝露现象，因此，空调器1需要或可能需要退出防凝露模式。
在一些示例中，当空调器1运行一段时间后，室内环境的温度和相对湿度可以达到相对稳定，在短时间内不会发生明显的变化，因此，在空调器1的运行过程中，若空调器1退出防凝露模式，由于此时当前温度信息和当前相对湿度信息以保持基本稳定，因而空调器1通常无需再次进入防凝露模式。
为了保证空调器1能够实现根据室内环境决定是否进入或退出防凝露模式，需要检测装置40及时对室内环境的当前温度和当前相对湿度进行监控。
示例性地，检测装置40可以每隔预定时间检测室内环境的变化后的当前温度和变化后的当前相对湿度，并将检测结果发送给第一控制器10，再由第一控制器10将该检测结果发送给第二控制器20，以使第二控制器20根据该检测结果在数据查找表中查询压缩机30对应的最大允许运行频率。从而保证空调器1能够根据室内环境的实际情况决定是否进入或退出防凝露模式，从而提高空调器1的适应性，提高用户体验。
在一些实施例中，预设时间可以为10分钟。其中，预设时间不能设置的过短，预设时间设置过短，会导致检测装置40频繁获取室内环境的当前温度和当前相对湿度，以使第二控制器20频繁地进行查表操作，频繁查表操作会在一定程度上增大空调器1的功率消耗且增大查找工作量；或者，预设时间也不能设置过长，若将预设时间设置得过长，会导致在室内环境的当前温度和当前相对湿度发生明显变化后，尤其是在室内环境的当前温度和当前相对湿度导致空调器1发生或容易发生凝露现象时，第二控制器20无法及时获 取到，从而导致空调器1不能及时适应性地进入防凝露模式。将预设时间设为10分钟，既可避免增大空调器1的功率消耗且使查找工作量相对低，又可确保空调器1及时地根据室内环境的当前温度和当前相对湿度的变化而在需要时进入防凝露模式，从而降低空调器1的运行成本，提高用户使用体验。
示例性地，预设时间也可以根据实际需要进行设定，例如，预设时间可以大于或小于10分钟，如预设时间还可以设定为5分钟、8分钟、9分钟、11分钟、12分钟或15分钟等。
在一些实施例中，在经过预设时间，室内环境的当前温度信息和当前相对湿度信息会发生变化，第一控制器10从检测装置40获取到变化后的当前温度信息和变化后的当前相对湿度信息后，再发送给第二控制器20，第二控制器20按照如图5所示的步骤51到步骤59来实现对压缩机30的运行频率的控制。
步骤51，经过预设时间，第一控制器10获取变化后的室内机100所处环境的当前温度信息和当前相对湿度信息，向第二控制器20发送变化后的当前温度信息和变化后的当前相对湿度信息。
其中，第一控制器10首次获取的为室内环境当前温度信息和当前相对湿度信息，在经过预设时间后，第一控制器10获取的为变化后的当前温度信息和变化后的当前相对湿度信息。
步骤52，第二控制器20接收变化后的当前温度信息和变化后的当前相对湿度信息。
步骤53，第二控制器20根据变化后的当前温度信息和变化后的当前相对湿度信息，查询预设对应关系，得到查询结果。
步骤54，第二控制器20确定查询结果是否为空。
若查询结果不为空，空调器1进入防凝露模式，继续执行步骤55；若查询结果为空，空调器1不进入(或者退出)防凝露模式，执行步骤59。
步骤55，第二控制器20确定变化后的当前温度信息和变化后的当前相对湿度信息在预设对应关系中对应的压缩机30的第二运行频率。
步骤56，第二控制器20确定第一运行频率是否大于第二运行频率。
其中，第一运行频率为压缩机30的当前运行频率，若第一运行频率大于第二运行频率，执行步骤57，若第一运行频率小于或等于第二运行频率，执行步骤58。
步骤57，第二控制器20控制压缩机30以第二运行频率运行。
在执行完步骤57后，继续返回步骤51，等待下一次(预设时间后)获取室内环境的变化后的当前温度信息和变化后的当前相对湿度信息，直至执行到步骤59，空调器1退出防凝露模式。
步骤58，第二控制器20控制压缩机30以第一运行频率运行。
在执行完步骤519后，继续返回步骤51，等待下一次(预设时间后)获得室内环境的变化后的当前温度信息和变化后的当前相对湿度信息，直至执行到步骤59，空调器1退出防凝露模式。
步骤59，第二控制器20控制压缩机30以第一运行频率运行。
由于第二控制器20的查询结果为空，因而空调器1不进入(或者退出)防凝露模式，第二控制器20控制压缩机30以当前运行频率运行(即第一运行频率)。
按照图5所示的过程，可以通过周期性地检测空调器1是否需要进入或退出防凝露模 式，以提高空调器1的适应性，提高用户的使用体验。
图6为本公开一些实施例提供的一种空调器的控制方法，参照图1，该空调器可以为上述实施例中的空调器1，空调器1包括室内机100和室外机200，其中，室内机100包括第一控制器10，室外机200包括第二控制器20和压缩机30。空调器的控制方法包括步骤61到步骤68。
步骤61，第二控制器20控制压缩机30以第一运行频率运行。
其中，压缩机30以第一运行频率运行，可以使室内机100所处环境的温度降低。
步骤62，第一控制器10获取室内机100所处环境的当前温度信息和当前相对湿度信息。
步骤63，第一控制器10向第二控制器20发送当前温度信息和当前相对湿度信息。
步骤64，第二控制器20接收当前温度信息和当前相对湿度信息。
步骤65，第二控制器20根据当前温度信息、当前相对湿度信息以及预设对应关系，确定当前温度信息和当前相对湿度信息在预设对应关系中对应的压缩机30的第二运行频率。
其中，预设对应关系包括多个温度信息和多个相对湿度信息与压缩机30的多个运行频率的对应关系。
步骤66，第二控制器20确定第一运行频率是否大于第二运行频率。
若确定第一运行频率大于第二运行频率，执行步骤67，若确定第一运行频率小于或等于第二运行频率，执行步骤68。
步骤67，第二控制器20控制压缩机30以第二运行频率运行。
步骤68，第二控制器20控制压缩机30以第一运行频率运行。
在一些实施例中，若当前温度信息对应的温度和/或当前相对湿度信息对应的相对湿度越大，第二控制器20根据当前温度信息和当前相对湿度信息确定的压缩机30的运行频率越小。
