膨胀阀105连接于室外换热器103与室内换热器201之间，由膨胀阀105的开度大小调节流经室外换热器103和室内换热器201的冷媒压力，以调节流通于室外换热器103和室内换热器201之间的冷媒流量。流通于室外换热器103和室内换热器201之间的冷媒的流量和压力将影响室外换热器103和室内换热器201的换热性能。膨胀阀105可以是电子阀。膨胀阀105的开度是可调节的，以控制流经膨胀阀105冷媒的流量和压力。
四通阀102连接于所述冷媒回路内，四通阀102受控于控制器30以切换冷媒在冷媒回路中的流向以使空调器1000执行制冷模式或制热模式。
室内换热器201被配置为将室内空气与在室内换热器201中传输的冷媒进行热交换。例如，室内换热器201在空调器1000的制冷模式下作为蒸发器进行工作，使得经由室外换热器103散热后的冷媒通过室内换热器201吸收室内空气的热量而蒸发；室内换热器201在空调器1000的制热模式下作为冷凝器进行工作，使得经由室外换热器103吸热后的冷媒通过室内换热器201将热量散发至室内空气而冷凝。
在一些实施例中，室内换热器201还包括换热翅片，以扩大室内空气与室内换热器201中传输的冷媒之间的接触面积，从而提高室内空气与冷媒之间的热交换效率。
第二风机202被配置为将室内空气经室内机20的室内进风口吸入至室内机20内，并将与室内换热器201换热后的室内空气经由室内机20的室内出风口送出。第二风机202为室内空气的流动提供动力。
控制器30被配置为控制压缩机101的工作频率、膨胀阀105的开度、第一风机104的转速和第二风机202的转速。控制器30与压缩机101、膨胀阀105、第一风机104和第二风机202通过数据线相连以传输通信信息。
控制器30包括处理器。处理器可以包括中央处理器(central processing unit,CPU))、微处理器(microprocessor)、专用集成电路(application specific integrated circuit,ASIC)，并且可以被配置为当处理器执行存储在耦合到控制器30的非暂时性计算机可读介质中的程序时，执行控制器30中描述的相应操作。非暂时性计算机可读存储介质可以包括磁存储设备(例如，硬盘、软盘、或磁带)、智能卡、或闪存设备(例如，可擦除可编程只读存储器(erasable programmable read-only memory,EPROM)、卡、棒、或键盘驱动器)。空调 器1000运行于制冷模式下时，室外换热器103作为冷凝器、室内换热器201作为蒸发器。冷凝器将其内部的冷媒的热量散发至室外空气中，蒸发器内的冷媒则吸收室内空气的热量以使室内温度降低，故冷凝器的温度高、蒸发器的温度低。当蒸发器的温度低于室内温度时，室内空气中的水蒸气就在蒸发器的表面冷凝成液态的水。尤其是夏季空气湿度大含有的水分多的时候，蒸发器的表面更容易形成冷凝水。
空调器1000的除湿模式(尤其是降温除湿模式)也正是利用空气中的水蒸气遇冷会被冷凝成液态水的原理而工作的。
空调器1000运行于制热模式下时，室外换热器103作为蒸发器、室内换热器201作为冷凝器。冷凝器将其内部的冷媒的热量散发至室内空气中以使室内温度升高，蒸发器内的冷媒则吸收室外空气的热量，故冷凝器的温度高、蒸发器的温度低。当蒸发器的温度低于室外温度时，室外空气中的水蒸气就在蒸发器的表面冷凝成液态的水。但一般冬季空气湿度小，含有的水分少，因此当空调器1000运行于制热模式下时蒸发器的表面不容易形成冷凝水。
上面描述了空调器1000为分体式空调器的示例，但本公开并不限于此。在一些实施例中，空调器1000也可以为一体式空调器。
如图2所示，空调器1000包括箱体40、第一风机104、第二风机202以及显示装置1001，在空调器1000运行制冷或除湿模式时，第一风机104位于箱体40的下部(N侧)，并被配置为对冷凝器和压缩机101进行散热，以降低冷凝器和压缩机101的温度；第二风机202位于箱体40的上部(M侧)，并被配置为促进空调器1000内部空气与外部空气的流通与交换。显示装置1001可以位于箱体40的上部位置处，通过显示装置1001可以显示空调器1000运行时的模式以及温度等信息。
需要说明的是，当空调器1000为一体式空调器时，室外换热器103位于箱体40内。示例性地，室外换热器103可通过管路与室外的空气连通；或者，室外换热器103与空调器1000的外部空气连通。
由上述分析可知，空调器1000在长时间运行制冷模式或除湿模式后会产生大量的冷凝水。因此，如图3所示，空调器1000还包括水槽1002、打水轮1003以及打水电机1004。
水槽1002被配置为容纳空调器1000运行过程中产生的冷凝水。由于室内换热器201和室外换热器103均有可能作为蒸发器使用，因此室内换热器201和室外换热器103所产生的冷凝水均流入到该水槽1002中。当以空调器1000运行制冷模式或除湿模式为示例时，水槽1002可以设置在室外换热器103的附近。
打水电机1004被配置为驱动打水轮1003旋转以将水槽1002内的所述冷凝水喷淋至冷凝器，通过冷凝器产生的热量可以对喷淋至冷凝器的冷凝水进 行蒸发，从而达到降低水槽1002内冷凝水的水位的目的。并且，还可以对冷凝器进行降温。当以空调器1000运行制冷模式或除湿模式为示例时，冷凝器指的是室外换热器103。
在一些实施例中，如图1和图3所示，空调器1000还包括第一水位开关1005、第二水位开关1006、第一温度传感器1007和第二温度传感器1008。
第一水位开关1005和第二水位开关1006被配置为检测水槽1002内冷凝水的水位。
第一温度传感器1007被配置为检测冷凝器的温度，第二温度传感器1008被配置为检测空调器1000外部的环境温度。
第一风机104被配置为对冷凝器和压缩机101进行散热，以降低冷凝器和压缩机101的温度，第二风机202被配置为促进空调器1000内部空气与外部空气的流通与交换。
空调器1000在制冷模式或除湿模式运行一段时间后，当冷凝水的累积速度大于冷凝器对冷凝水的蒸发速度时，即使通过冷凝器对水槽1002内的冷凝水进行蒸发，冷凝水的水位仍然会不断升高。因此，需要及时对水槽1002内的冷凝水的水位进行控制。
如图4所示，本公开一些实施例提供了一种空调器的水位控制方法，所述水位控制方法可以应用于一体式空调器(如移动空调器等)或分体式空调。该空调器的水位控制方法包括步骤1至步骤4。
在步骤1中，控制器30判断冷凝水的水位是否达到第一预设水位A。
示例性地，参照图3，第一预设水位A可以为水槽1002最大容量的三分之二。可以通过第一水位开关1005检测水槽1002内冷凝水的水位是否达到第一预设水位A，并将检测结果发送至控制器30。第一水位开关1005可以采用电容式液位开关或浮球式液位开关。
在步骤2中，若冷凝水的水位达到第一预设水位A，则控制器30控制第一风机104以最低转速运行且控制打水电机1004以最高转速运行，并检测冷凝器温度T，根据冷凝器温度T控制压缩机101的运行频率。
示例性地，第一风机104的转速范围为650r/min～1000r/min(例如，650r/min、750r/min、850r/min、950r/min或1000r/min)。此时，第一风机104的最低转速为650r/min。
由于打水电机1004的实际转速受到水槽1002内冷凝水水量的影响，使得打水电机1004的实际转速与理想的转速存在偏差，因此，在一些实施例中，可以选取打水电机1004在空转情况下的最高转速(例如，3700r/min)为打水电机1004的最高转速。
示例性地，可以通过第一温度传感器1007检测冷凝器温度T。通过控制器30可以控制第一风机104和打水电机1004的转速以及压缩机101的运行 频率。
本公开一些实施例的空调器的水位控制方法的逻辑(软件)可以写入空调器1000的控制器30。
需要说明的是，在检测冷凝器温度T之前，空调器1000需要预先运行20分钟～30分钟。在运行20分钟～30分钟后，空调器1000运行较为稳定。此时，冷凝器温度T逐渐升高。在这样的情况下，控制器30通过第一温度传感器1007检测冷凝器温度T，并根据冷凝器温度T能够更准确地控制压缩机101的运行频率。
在一些实施例中，如图5所示，根据冷凝器温度T控制压缩机101的运行频率，包括步骤21至步骤25。
在步骤21中，控制器30判断冷凝器温度T是否小于或等于第一预设温度T 1。
在步骤22中，若冷凝器温度T小于或等于第一预设温度T 1，则控制器30提高压缩机101的运行频率。
在步骤23中，若冷凝器温度T大于第一预设温度T 1，则控制器30判断冷凝器温度T是否小于第二预设温度T 2。
在步骤24中，若冷凝器温度T大于第一预设温度T 1且小于第二预设温度T 2，则控制器30降低压缩机101的运行频率。
在步骤25中，若冷凝器温度T大于或等于第二预设温度T 2，则控制器30控制第一风机104以最高转速运行且控制打水电机1004以最高转速运行，并检测环境温度T 0，根据所述环境温度T 0控制压缩机101的运行频率。
所述环境温度T 0可以通过第二温度传感器1008进行检测。
在本公开的一些实施例中，当水槽1002中的冷凝水的水位达到第一预设水位A时，通过控制第一风机104以最低转速运行，降低第一风机104对冷凝器的散热效果，由于空调器1000仍处于运行状态，从而能够使冷凝器产生热量，利于加快冷凝水的蒸发速度。并且，通过控制打水电机1004以最高转速运行，从而能够加快打水电机1004将水槽1002中的冷凝水喷淋至冷凝器的速度，这样，使得水槽1002中的冷凝水能够快速地被冷凝器蒸发，达到降低冷凝水的水位的目的。
然而，在一些实施例中，在第一风机104以最低转速运行且打水电机1004以最高转速运行的情况下，水槽1002中的冷凝水的水位仍可能继续升高。当冷凝器温度T小于或等于第一预设温度T 1时,冷凝器温度T仍有提升空间，通过提高压缩机101的运行频率，可以提升冷凝器的换热效率，从而提升空调器1000的制冷能力并且加快冷凝水的蒸发。
当冷凝器温度T大于第一预设温度T 1且小于第二预设温度T 2时，冷凝器温度T较高，控制器30需要控制降低压缩机101的运行频率，防止因冷凝器 温度T过高而造成冷凝器损坏，从而提高空调器1000的整机安全性。并且，当压缩机101的运行频率被降低时，冷凝水的产生速度也会相应降低，从而可以达到降低水槽1002内的冷凝水的水位上升速度的目的。
当冷凝器温度T大于或等于第二预设温度T 2时，表明冷凝器温度T过高(例如，接近冷凝器所能承受的温度最大值47℃)，冷凝器容易损坏，因此，需要控制提高第一风机104的转速以提高第一风机104对冷凝器的散热效果，从而降低冷凝器温度T。
此外，控制器30还可以根据环境温度T 0判断空调器1000运行时是否负载较大，从而降低压缩机101的运行频率。
在一些实施例中，如图6所示，根据所述环境温度T 0控制压缩机101的运行频率，包括步骤251至步骤253。
在步骤251中，控制器30判断环境温度T 0是否大于第一预设环境温度T 01。
在步骤252中，若环境温度T 0大于第一预设环境温度T 01，则控制器30控制压缩机101停机。
在步骤253中，若环境温度T 0小于或等于第一预设环境温度T 01，则控制器30控制降低压缩机101的运行频率。
例如，当环境温度T 0大于第一预设环境温度T 01时，表明此时冷凝器温度T和环境温度T 0均较高，压缩机101的负载很大，冷凝器产生的热量无法将冷凝水及时蒸发。因此，控制器30需要控制压缩机101停机，避免因压缩机101继续运行使冷凝器温度T继续升高而造成冷凝器的损坏；并且，通过控制器30控制压缩机101停机，还可以避免因水槽1002内冷凝水的水位继续上升而使冷凝水溢出。
当环境温度T 0小于或等于第一预设环境温度T 01时，虽然冷凝器温度T很高(例如，冷凝器温度T大于45℃)，但环境温度T 0并不高。此时，通过控制器30降低压缩机101的运行频率即可避免冷凝器温度T过高(例如，冷凝器温度T大于47℃)，使得空调器1000仍能够继续运行。
在一些实施例中，第一预设温度T 1为36℃～40℃，第二预设温度T 2为43℃～47℃，第一预设环境温度T 01为30℃～34℃。
这里，第一预设温度T 1、第二预设温度T 2和第一预设环境温度T 01可以根据空调器的型号合理地进行选取。例如，第一预设温度T 1可以为36℃、38℃或40℃等，第二预设温度T 2可以为43℃、45℃或47℃等，第一预设环境温度T 01可以为30℃、32℃或34℃等。
冷凝器温度T和环境温度T 0分别具有不同的判断预设值(即，冷凝器温度T与第一预设温度T 1和第二预设温度T 2对应，环境温度T 0与第一预设环境温度T 01对应)。
参照图4至图6，在步骤3中，控制器30判断冷凝水的水位是否达到第二预设水位B。
示例性地，参照图3，第二预设水位B为水槽1002的最大容量，第二预设水位B高于第一预设水位A设置。可以通过第二水位开关1006检测水槽1002内的冷凝水的水位是否达到第二预设水位B。第二水位开关1006可以采用电容式液位开关或浮球式液位开关。
需要说明的是，上述对第一预设水位A以及第二预设水位B的描述只是示例性地，不能理解为对本公开的限制。第一预设水位A和第二预设水位B的具体位置可以根据实际情况而适应性设置。
需要说明的是，参照图3，水槽1002包括水槽本体10021以及与水槽本体10021相连的防溢槽10022。示例性地，防溢槽10022的容量大致为水槽本体10021的最大容量的三分之一。当冷凝水的水位达到第二预设水位B时，冷凝水如果不能够被冷凝器及时蒸发，则可以通过防溢槽10022进行承接，从而能够避免因冷凝器不能及时蒸发冷凝水而导致冷凝水从水槽1002中溢出的情况。
这里，上文描述的水槽1002的最大容量即是水槽本体10021的最大容量。
参照图4至图6，在步骤4中，若冷凝水的水位达到第二预设水位B，则控制器30检测冷凝器温度T和环境温度T 0，并根据冷凝器温度T和环境温度T 0控制压缩机101是否停机。
示例性地，可以通过第一温度传感器1007检测冷凝器温度T，通过第二温度传感器1008检测环境温度T 0。
当冷凝水的水位达到第二预设水位B时，控制器30根据检测到的冷凝器温度T和环境温度T 0控制压缩机101是否停机。例如，当冷凝器温度T和环境温度T 0过高(例如，冷凝器温度T大于47℃、环境温度T 0大于34℃)时，表明此时空调器1000的负载较大，冷凝器对冷凝水的蒸发能力不足，水槽1002中冷凝水的水位在冷凝器的蒸发作用下仍无法有效降低。为避免因冷凝水的水位过高(例如，达到第二预设水位B)，以及冷凝器温度T过高而造成安全隐患，控制器30需要及时控制压缩机101停机。
在一些实施例中，如图4至图6所示，步骤4：若冷凝水的水位达到第二预设水位B，则控制器30根据冷凝器温度T和环境温度T 0控制压缩机101是否停机，所述步骤4还包括步骤41至步骤43。
如图7所示，在步骤41中，控制器30判断冷凝器温度T是否小于第三预设温度T 3且环境温度T 0是否小于第二预设环境温度T 02。
在步骤42中，若冷凝器温度T大于或等于第三预设温度T 3，或者环境温度T 0大于或等于第二预设环境温度T 02，则控制器30控制压缩机101停机。
当冷凝水的水位达到第二预设水位B时，控制器30需要及时降低冷凝水 的水位。控制器30通过判断冷凝器温度T和环境温度T 0，控制压缩机101是否停机。
例如，当冷凝器温度T大于或等于第三预设温度T 3，或者环境温度T 0大于或等于第二预设环境温度T 02时，表明此时空调器1000的负载较大，控制器30需要及时控制压缩机101停机，以避免因压缩机101运行而继续产生冷凝水，从而能够防止冷凝水溢出；并且，通过控制器30控制压缩机101停机，还可以防止冷凝器温度T继续升高，进而保证空调器1000的安全性。
在步骤43中，若冷凝器温度T小于第三预设温度T 3且环境温度T 0小于第二预设环境温度T 02，则控制器30控制第一风机104以最低转速运行以及控制第二风机202以最高转速运行并且提高压缩机101的运行频率。
例如，当冷凝器温度T小于第三预设温度T 3且环境温度T 0小于第二预设环境温度T 02时，表明此时冷凝器温度T仍有提升空间，压缩机101仍可运行。通过提高压缩机101的运行频率，可以加快冷凝水的蒸发速度，从而降低冷凝水的水位。并且，通过控制第二风机202高速运行，可以加快冷凝水蒸发后的水汽向室外排出的速度，降低空调器1000内部的水汽含量，从而促进冷凝器蒸发冷凝水。
示例性地，第二风机202的转速为750r/min～1200r/min(例如，750r/min、850r/min、950r/min、1050r/min或1200r/min)。此时，第二风机202的最高转速为1200r/min。
在一些实施例中，如图8所示，在步骤43之后，所述步骤4还包括步骤44至步骤49。
在步骤44中，若冷凝器温度T小于第三预设温度T 3且环境温度T 0小于第二预设环境温度T 02，则开始计时。
示例性地，可以通过计时器对冷凝器温度T小于第三预设温度T 3且环境温度T 0小于第二预设环境温度T 02的持续时间t进行计时。
需要说明的是，在冷凝器温度T小于第三预设温度T 3且环境温度T 0小于第二预设环境温度T 02的条件未满足之前，所述计时器的初始值为零。
在步骤45中，控制器30获取冷凝器温度T从小于第三预设温度T 3且环境温度T 0小于第二预设环境温度T 02变为冷凝器温度T大于或等于第三预设温度T 3，或者环境温度T 0大于或等于第二预设环境温度T 02的持续时间t。
在步骤46中，控制器30判断持续时间t是否达到预定时间t 0。若否，则返回执行步骤41；若是，则执行步骤47。
示例性地，当持续时间t未达到预定时间t 0时，冷凝器温度T有可能升高至大于或等于第三预设温度T 3，或者环境温度T 0升高至大于或等于第二预设环境温度T 02。此时，空调器1000的运行工况较为恶劣，冷凝器无法及时将冷凝水蒸发。因此，需要及时控制压缩机101停机，避免冷凝器的温度过高， 并且避免冷凝水的水位继续上升。
在步骤47中，若持续时间t大于或等于预定时间t 0，则控制器30判断冷凝水的水位是否达到第二预设水位B。
在步骤48中，若冷凝水的水位达到第二预设水位B，则控制器30控制压缩机101停机。
示例性地，当持续时间t未达到预定时间t 0时，冷凝器持续蒸发冷凝水。当持续时间t达到预定时间t 0时，若冷凝水的水位达到第二预设水位B，即表明此时冷凝水的水位仍然很高。为避免冷凝水的水位继续上升，控制器30需要及时控制压缩机101停机，避免继续产生冷凝水，从而防止冷凝水溢出；并且，通过控制器30控制压缩机101停机，还可以防止冷凝器温度T继续升高，进而保证空调器1000的安全性。
示例性地，在压缩机101停机时，空调器1000的显示装置1001(例如，显示屏等)可以显示故障代码，使用户及时发现冷凝水的水位过高的问题，以及时采取应对措施。
若冷凝水的水位未达到第二预设水位B，则控制器30返回执行步骤1。
示例性地，当持续时间t达到预定时间t 0时，若冷凝水的水位低于第二预设水位B，即表明冷凝水的水位已经下降。此时，控制器30再次判断冷凝水的水位是否达到第一预设水位A(即上述的返回执行步骤1)。
在一些实施例中，预定时间t 0为28min～60min，例如，预定时间t 0可以为28min、30min、45min或60min等。
在预定时间t 0内，虽然冷凝器持续蒸发冷凝水，但冷凝水的水位仍可能升高或降低。当预定时间t 0为30min或60min时，若冷凝水的水位升高，冷凝水也不会溢出；并且，上述预定时间t 0也可满足蒸发冷凝水的需要。
此外，当持续时间t达到预定时间t 0后再判断冷凝水的水位是否仍达到第二预设水位B，利于保证空调器1000的安全运行。
在一些实施例中，第三预设温度T 3为43℃～47℃，第二预设环境温度T 02为30℃～34℃。
例如，第三预设温度T 3为43℃、45℃或47℃等，第二预设环境温度T 02为30℃、32℃或34℃等。从而达到及时准确的控制冷凝器温度T和环境温度T 0的目的。
示例性地，所述第三预设温度T 3与所述第二预设温度T 2可以相等或不相等，所述第二预设环境温度T 02与所述第一预设环境温度T 01可以相等或不相等。
以下结合图9和图10对本公开一些实施例的空调器的水位控制方法做示例性说明。
当空调器1000在制冷模式或除湿模式下运行时，空调器1000产生的冷 凝水流入至水槽1002。
如图9所示，当检测到冷凝水的水位达到第一预设水位A时，控制器30控制第一风机104以最低转速运行且控制打水电机1004以最高转速运行。控制器30获取第一温度传感器1007检测到的冷凝器温度T，并判断冷凝器温度T是否小于或等于第一预设温度T 1。当冷凝器温度T小于或等于第一预设温度T 1时，则控制器30控制提高压缩机101的运行频率。
当冷凝器温度T大于第一预设温度T 1时，则控制器30进一步判断冷凝器温度T是否小于第二预设温度T 2。若冷凝器温度T大于第一预设温度T 1且小于第二预设温度T 2，则控制器30降低压缩机101的运行频率。
若冷凝器温度T大于或等于第二预设温度T 2，则控制器30控制第一风机104以最高转速运行且控制打水电机1004以最高转速运行，并且通过第二温度传感器1008获取环境温度T 0，判断环境温度T 0是否大于第一预设环境温度T 01。若环境温度T 0大于第一预设环境温度T 01，则控制器30控制压缩机101停机。若环境温度T 0小于或等于第一预设环境温度T 01，则控制器30降低压缩机101的运行频率。
如图10所示，当检测到冷凝水的水位达到第二预设水位B时，控制器30判断冷凝器温度T是否小于第三预设温度T 3且环境温度T 0是否小于第二预设环境温度T 02。
若冷凝器温度T大于或等于第三预设温度T 3，或者环境温度T 0大于或等于第二预设环境温度T 02，则控制器30控制压缩机101停机，显示故障代码。
若冷凝器温度T小于第三预设温度T 3且环境温度T 0小于第二预设环境温度T 02，则控制器30控制第一风机104以最低转速运行，打水电机1004以最高转速运行以及控制第二风机202以最高转速运行并且提高压缩机101的运行频率。
当冷凝器温度T小于第三预设温度T 3且环境温度T 0小于第二预设环境温度T 02时，通过计时器对冷凝器温度T小于第三预设温度T 3且环境温度T 0小于第二预设环境温度T 02的持续时间t进行计时。所述计时器在开始对所述持续时间t进行计时之前的初始值为0。
判断持续时间t是否达到预定时间t 0，当持续时间t未达到预定时间t 0时，若在计时过程中冷凝器温度T大于或等于第三预设温度T 3，或者环境温度T 0大于或等于第二预设环境温度T 02，则控制器30控制压缩机101停机。
当持续时间t达到预定时间t 0时，控制器30进一步判断冷凝水的水位是否达到第二预设水位B。若冷凝水的水位达到第二预设水位B，则控制器30控制压缩机101停机，显示故障代码。若冷凝水的水位未达到第二预设水位B，则控制器30判断冷凝水的水位是否达到第一预设水位A。
