图1是根据一示例性实施例示出的一种空调器的结构示意图。如图1所示，本发明一种实施方式的空调器，包括：压缩机1、室内换热器15、室外换热器5和节流组件，所述室内换热器15包括两个不连通的分区；所述节流组件包括第一节流装置9和第二节流装置10，制冷剂分别经所述第一节流装置9和所述第二节流装置10进入所述室内换热器15的两个分区；还包括：控制装置，连接所述第一节流装置和所述第二节流装置，用于在所述空调器处于恒温除湿模式时，控制所述第一节流装置9和所述第二节流装置10的开度，以分别调节所述室内换热器15的两个分区的温度不同时高于环境温度或不同时低于环境温度。
上述方案中，高温高压的制冷剂从压缩机1排出，经过四通阀4、室外换热器5、和热力膨胀阀6或在制热时经单向阀7后，经过两个节流装置9和10传输到室内换热器15 的两个不连通的分区，调节两个节流装置的开度，使其中一个节流装置调节制冷剂的温度低于室内环境温度，例如第一节流装置9作为弱制冷用，以进行除湿，例如在使其阀开度较小的情况下，制冷剂从气液混合的状态经第一节流装置9转换为液态，进入室内换热器15的其中一个分区，使其处于弱制冷模式，室内环境中的水分在低温状态下凝结成液态水，达到除湿的效果；而另一个节流装置，第二节流装置10将压缩机1排出的高温高压的制冷剂传输至室内，调节第二节流装置10的开度，使制冷剂在不改变相态的情况下进入室内换热器15的另一个分区，达到弱制热模式，以进行温度补偿；室内换热器的两个分区呈现的效果为一个弱制冷除湿，另一个弱制热进行温度补偿，两个分区共同作用实现恒温除湿的功能。上述方案的空调器，在不增加附加的除湿装置的情况下进行除湿，简化空调器的结构，节省制造和购买成本，节约资源；且除湿是在恒温的条件下进行，不对室内温度进行改变，提高用户使用的舒适度，提高空调器产品力。
上述方案中，所述第一节流装置9和所述第二节流装置10为电子膨胀阀或热力膨胀阀。
图2是根据一示例性实施例示出的一种空调器的结构示意图。如图2所示，本发明一种实施方式的空调器，还包括：第一温度检测装置13，用于检测经所述第一节流装置9调节后的温度；第二温度检测装置14，用于检测经所述第二节流装置10调节后的温度；环境温度检测装置17，用于检测环境温度；所述控制装置还用于根据所述第一温度检测装置13检测的温度和所述第二温度检测装置14检测的温度确定平均温度，并根据所述平均温度与所述环境温度的差值调节所述第一节流装置9和所述第二节流装置10的开度。
上述方案中，所述控制装置还用于：当所述平均温度与所述环境温度的差值大于或等于所述温差设定值时，调节所述第一节流装置9或第二节流装置10中低于所述环境温度的节流装置的开度增加，此处第一节流装置9为作为弱制冷的节流装置，调节第一节流装置9的开度增加，以使得经该节流装置调节的制冷剂的温度降低。
上述方案中，还设置第一温度检测装置13和第二温度检测装置14以对两个节流装置调节的制冷剂温度进行检测，以实现温度的精确调节。当需要进行恒温调节时，通过第一温度检测装置13检测第一节流装置9调节后的制冷剂的温度，使用第二温度检测装置14检测第二节流装置10调节后的制冷剂的温度，确定二者的平均温度，以确定进行温度补偿后的温度值，根据该平均温度与使用环境温度检测装置17检测的室内环境温度的差值确定恒温除湿对室内环境温度的影响，当平均温度与室内环境温度的差值大于或等于温差设定值时，表明室内环境温度高于预期/设定，此时，调节处于弱制冷模式的节流装置的 开度增大，使通过的制冷剂增多，以降低室内环境温度；而当平均温度小于温差设定值时，表明两个节流装置调节后的温度低于室内环境温度，此时的调节方式与上述的高于温差设定值时相反，即减小弱制冷的节流装置的开度，降低制冷剂的通过量；或者，作为另外一种示例，增大弱制热状态的节流装置的开度，以提高室内环境温度。上述方案的方法，对弱制冷和弱制热的节流装置调节后的制冷剂的温度进行检测，与室内环境温度进行对比，确定调节的方式，以对室内环境温度进行监控和精确调节，保证恒温除湿的工作模式的精确度，提高空调器的智能化，提高用户使用舒适度。
上述方案中，环境温度检测装置17为第一环境温度检测装置，设置在室内换热器15的回风侧，作为另一示例，还包括第二环境温度检测装置18，设置在室内换热器15的出风侧。将第一环境温度检测装置17检测的环境温度和第二环境温度检测装置18检测的温度加权求平均，确定环境温度。
上述方案中，所述温差设定值为0℃。上述方案中，当空调器工作在恒温除湿工作模式下，温差设定值为0℃；而当空调器处于弱制冷除湿模式下时，温差设定值可以设置为低于0℃，例如-2℃；而当空调器处于弱制热除湿模式下时，温差设定值可以设置为高于0℃，例如2℃；实现除湿时的恒温、弱制冷、弱制热工作模式。
上述方案中，还包括：第三温度检测装置11和第四温度检测装置12，分别与第一温度检测装置13和第二温度检测装置14对应设置，分别设置在第一节流装置9和第二节流装置10的前端，以对第一节流装置9和第二节流装置10调节前的制冷剂温度进行检测。第三温度检测装置11和第四温度检测装置12分别与第一温度检测装置11和第二温度检测装置14配合，分别用于对第一节流装置9和第二节流装置10的过冷度进行调节。
上述方案中，第一节流装置9和第二节流装置10为电子膨胀阀。第三温度检测装置和第四温度检测装置用于对电子膨胀阀9和10的过冷度进行调节。
图3是根据一示例性实施例示出的一种用于空调器的控制方法的流程示意图。如图3所示，本发明一种实施方式的用于空调器的控制方法，所述空调器包括：压缩机、室内换热器、室外换热器和节流组件，所述室内换热器包括两个不连通的分区，所述节流组件包括第一节流装置和第二节流装置，制冷剂分别经所述第一节流装置和所述第二节流装置进入所述室内换热器的两个分区；以及，控制装置，用于调节所述第一节流装置和所述第二节流装置的开度，如图1或2所示；该方法包括：在步骤S110中，检测经所述第一节流装置的制冷剂的温度；在步骤S112中，检测经所述第二节流装置的制冷剂的温度；在步骤S114中，检测环境温度；在步骤S120中，确定所述第一节流装置的制冷剂的温度和经 所述第二节流装置的制冷剂的温度的平均温度与所述环境温度的差值；在步骤S130中，根据所述差值调节所述第一节流装置和所述第二节流装置的开度。
上述方案中，高温高压的制冷剂从压缩机排出，经过两个节流装置传输到室内换热器的两个不连通的分区，调节两个节流装置的开度，使其中一个节流装置调节制冷剂的温度低于室内环境温度，以进行除湿，例如在使其阀开度较小的情况下，制冷剂从气液混合的状态经节流装置转换为液态，进入室内换热器的其中一个分区，使其处于弱制冷模式，室内环境中的水分在低温状态下凝结成液态水，达到除湿的效果；而另一个节流装置将压缩机排出的高温高压的制冷剂传输至室内，调节该节流装置的开度，使制冷剂在不改变相态的情况下进入室内换热器的另一个分区，达到弱制热模式，以进行温度补偿；室内换热器的两个分区呈现的效果为一个弱制冷除湿，另一个弱制热进行温度补偿，两个分区共同作用实现恒温除湿的功能。上述方案的空调器，在不增加附加的除湿装置的情况下进行除湿，简化空调器的结构，节省制造和购买成本，节约资源；且除湿是在恒温的条件下进行，不对室内温度进行改变，提高用户使用的舒适度，提高空调器产品力。
上述方案中，当所述空调器处于低温除湿模式时，调节流经两个节流装置的制冷剂温度中的一者高于所述环境温度，另一者低于所述环境温度。
图4是根据一示例性实施例示出的一种用于空调器的控制方法的流程示意图。如图4所示，本发明一种实施方式的用于空调器的控制方法，在步骤S132中，判断平均温度与环境温度的差值是否大于或等于差值设定值，当所述差值大于或等于温差设定值时，在步骤S134中，调节制冷剂温度低于所述环境温度的节流装置的开度增大，即调节第一节流装置的开度增大，和/或调节第二节流装置的开度减小，使得流经该节流装置的制冷剂的温度降低。
上述方案中，当所述差值小于温差设定值时，在步骤S136中，调节制冷剂温度低于所述环境温度的节流装置的开度减小，即第一节流装置的开度减小，使得流经该节流装置的制冷剂的温度升高。或调节第二节流装置的开度增大，同样达到使平均温度升高的效果，继而提高室内环境温度。
当所述差值等于温差设定值时，保持第一节流装置和第二节流装置的阀的开度不便，以维持现有环境温度。
上述方案中，所述温差设定值为0℃。
上述方案中，对两个节流装置调节的制冷剂温度进行检测，以实现温度的精确调节。当需要进行恒温调节时，检测第一节流装置调节后的制冷剂的温度，检测第二节流装置调 节后的制冷剂的温度，确定二者的平均温度，以确定进行温度补偿后的温度值，根据该平均温度与室内环境温度的差值确定恒温除湿对室内环境温度的影响，当平均温度与室内环境温度的差值大于或等于温差设定值时，表明室内环境温度高于预期/设定，此时，调节处于弱制冷模式的节流装置的开度增大，使通过的制冷剂增多，以降低室内环境温度；而当平均温度小于温差设定值时，表明两个节流装置调节后的温度低于室内环境温度，此时的调节方式与上述的高于温差设定值时相反，即减小弱制冷的节流装置的开度，降低制冷剂的通过量；或者，作为另外一种示例，增大弱制热状态的节流装置的开度，以提高室内环境温度。上述方案的方法，对弱制冷和弱制热的节流装置调节后的制冷剂的温度进行检测，与室内环境温度进行对比，确定调节的方式，以对室内环境温度进行监控和精确调节，保证恒温除湿的工作模式的精确度，提高空调器的智能化，提高用户使用舒适度。
图5是根据另一示例性实施例示出的用于空调器的控制方法的流程示意图。如图5所示，本发明另一种实施方式的用于空调器的控制方法，还包括：在调整第一节流装置或第二节流装置的阀开度后，循环检测将第一节流装置和第二节流装置调节后的制冷剂的温度，以及环境温度，并根据图3或图4所示的方法对第一节流装置或第二节流装置的阀的开度进行调节。使得通过第一节流装置与第二节流装置综合作用后，环境温度不改变或按照设定值变化，实现恒温除湿的目的。
如下为一示例性实施例的用于空调器的控制方法的控制逻辑：
1.空调器在开启恒温除湿模式时，室内机风扇先开启运转20s时(或用a秒表示)，通过检测到的第一环境温度检测装置/传感器17和第二环境温度检测装置/传感器18的均值，来获取当前房间的室内环境温度；
2.室内机的控制装置/电脑板发出指令给室外机换热器，压缩机启动运转，启动运转时，室内换热器相关联的第一节流装置/电子膨胀阀和第二节流装置/电子膨胀阀均以阀门全开时的步数为基准的1/4开启直到启动过程结束，即室外换热器正常运转时；
此过程外机电子膨胀阀6始终保持全开状态，通过室内机的第一节流装置/电子膨胀阀9和第二节流装置/电子膨胀阀10节流；
3.室内机的第一节流装置/电子膨胀阀9和第二节流装置/电子膨胀阀10通过各自的阀前和阀后的温度传感器即第三温度检测装置11和第一温度检测装置13，以及第四温度检测装置12和第二温度检测装置14分别进行过冷度控制，例如过冷度设定值为2℃，依据这一目标进行阀的开度调节。
示例：
如果过冷度＞2℃(阀前的温度传感器温度减去阀后温度传感器的温度，例如，第四温度检测装置12和第二温度检测装置14的差值是第二节流装置/电子膨胀阀10的过冷度)。节流装置/电子膨胀阀在现有步数上进行开阀，以降低其过冷度。
如果过冷度＜2℃，节流装置/电子膨胀阀在现有的步数上关阀。
如果过冷度＝2℃，节流装置/电子膨胀阀维持现有的步数。
第一节流装置/电子膨胀阀9和第二节流装置/电子膨胀阀10不以同一过冷度设定值作为目标进行调节，如果同时调节，将跟普通空调器的在室内机设置一个电子膨胀阀进行调节的运行过程相同，本发明的具有恒温除湿功能的空调器以及控制方法在于控制第一节流装置/电子膨胀阀9和第二节流装置/电子膨胀阀10的两路冷媒温度不同才能实现恒温除湿的效果。
第一节流装置/电子膨胀阀9和第二节流装置/电子膨胀阀10的作用和功能相同。例如，恒温除湿模式下开机后，第一节流装置/电子膨胀阀9调节控制进入室内换热器的冷媒是凉的，即在弱制冷状态；第二节流装置/电子膨胀阀10调节控制进入室内换热器的冷媒是热的，两路冷媒控制的室内换热器就会有冷热之分，流经室内换热器的空气也会有冷热区别，从而实现低温除湿和高温补偿。下次开机或累计此状态运行一定时间后，第一节流装置/电子膨胀阀9和第二节流装置/电子膨胀阀10的工作模式进行互换；
4.通过检测节流装置/电子膨胀阀后的温度检测装置/温度传感器13/14的温度，通过计算，例如通过相加后取平均值(或可以结合风扇转速，套用不同的公式进行计算预计的温度值)，得出的数值与环境温度(温度传感器17/18检测得出，一般都是两者之和再除以2)进行比较，如果高于环境温度，那么对第一节流装置/电子膨胀阀9开大(如果电子膨胀阀9控制冷的冷媒，那么将其过冷度降低，例如从2℃变为1℃)，同时对第二节流装置/电子膨胀阀10维持现状，持续检测以上温差再决定是否对第二节流装置/电子膨胀阀10进行关阀调整；
如果温度检测装置/温度传感器13/14的温度的平均值(或套用公式得出的数值)，低于环境温度，那么控制方法相比以上是相反的；
5.闭环调节逐渐达到恒温除湿的目的；
6.如果用户设定除湿过程的温度并非当前机器运转时的温度，例如设定低于开机时的温度，那么，温度检测装置/温度传感器13/14通过公式套算出来的数值再与环境温度进行比较，逐渐调节两个室内换热器的第一节流装置/电子膨胀阀9和第二节流装置/电子膨胀阀10的开度以达到设定温度的目的。
本发明实施方式的空调器及用于空调器的控制方法，利用制冷对环境进行除湿，利用制热对温度进行补偿，在不降低环境温度的情况下进行除湿，实现恒温除湿，提高用户的使用舒适度。
