通常，室内加湿有湿膜加湿、蒸汽加湿等，此类加湿方式需要单独的加湿装置连接新风机并且供水才能实现。加湿装置、新风机以及供水组件之间需要管路进行连接，结构复杂，而且占用空间大。或者，将加湿装置设置于新风机内，这样缩短了管路连接所需要的 长度，但是加湿装置在新风机中占用空间较大，且管路连接仍较为复杂，使新风机整体占用空间较大。或者，夏季室外空气湿度大，室外新风携带的水分需先经过吸附材料的吸收，再经过室内排风将吸附材料中的水分带走，从而实现使室外新风中携带的水分无法进入室内的目的；过程中需要换热器不断从蒸发器变成冷凝器，再由冷凝器变成蒸发器，而新风气流流向和排风气流流向也需要不断的相互之间进行切换。切换新风气流流向和排风气流流向的切换阀的数量较多，结构较为复杂，不利于后期安装和检修，且占用空间大以及工作噪音高。

转换阀160上的开关件162转动到与限位隔挡170抵接时停止转动，在限位隔挡170的作用下，实现进风端口120与第一换热端口140或第二换热端口150的切换。
限位隔挡170可以减小开关件162相对于转换主体110的内壁的转动过程中产生的阻力和摩擦力，使得转动过程更加顺畅，减小开关件162转动过程中产生的噪音。限位隔挡170还可以将开关件162固定在预设位置，避免开关件162在两侧风压作用下被损坏。

第一驱动装置1831设置在第一连杆184与交叉部1814连接处，第一驱动装置1831能够驱动第一连杆184顺时针或逆时针转动，从而带动多个导杆1821同时运动。
如图15所示，当第一驱动装置1831带动第一连杆184沿第一方向(如逆时针方向)转动时，在第一连杆184的带动下，第一子导杆18211和第二子导杆18212、第三子导杆18213和第四子导杆18214分别带动第一子百叶18221、第二子百叶18222、第三子百叶18223和第四子百叶18224分别绕与凸起部1813的连接轴沿逆时针方向转动。
当第三子导杆18213和第四子导杆18214与第二固定部1812贴合时，第一连杆184沿逆时针转动至第一极限位置，此时位于第二固定部1812上的第三子百叶18223与第四子百叶18224盖合在开口1815上，即位于第二固定部1812上的第三子百叶18223与第四子百叶18224关闭。同时，位于第一固定部1811的第一子百叶18221和第二子百叶18222与第一固定部1811呈最大角度，即位于第一固定部1811上的第一子百叶18221和第二子百叶18222开启。
当第一驱动装置1831带动第一连杆184沿第二方向(如顺时针方向)转动时，在第一连杆184的带动下，第一子导杆18211、第二子导杆18212、第三子导杆18213和第四子导杆18214带动第一子百叶18221、第二子百叶18222、第三子百叶18223和第四子百叶18224分别绕与凸起部1813的连接轴沿顺时针方向转动。
当第一子导杆18211和第二子导杆18212与第一固定部1811贴合时。第一连杆184沿顺时针转动至第二极限位置，此时位于第一固定部1811上的第一子百叶18221和第二子百叶18222盖合在开口1815上，即位于第一固定部1811上的第一子百叶18221和第二子百叶18222闭合。同时，第三子百叶18223和第四子百叶18224与第二固定部1812呈最大角度，即位于第二固定部1812上的第三子百叶18223和第四子百叶18224开启。
本公开仅通过一个驱动装置即可实现多个子腔之间连通或者闭合的效果，有利于降低成本。
在一些实施例中，新风机1000的驱动装置有两个，如图16至图18所示，分别为第二驱动装置1832和第三驱动装置1833。第二驱动装置1832和第三驱动装置1833分别位于交叉部1814的两侧。
连杆有多个，例如连杆有两个，分别为第二连杆185和第三连杆186，第二连杆185包括A端和B端，第三连杆186包括C端和D端。第二连杆185与第二驱动装置1832可转动连接，第三连杆186与第三驱动装置1833可转动连接。
第二连杆185的A端与第一子导杆18211可转动连接，第二连杆185的B端与第二子导杆18212可转动连接。第一子导杆18211、第二子导杆18212与第二连杆185组成摇杆机构。第三连杆186的C端与第三子导杆18213可转动连接，第三连杆186的D端与第四子导杆18214可转动连接。第三子导杆18213和第四子导杆18214与第二子连杆组成摇杆机构。
此时，第二连杆185或第三连杆186不再带动第一子导杆18211、第二子导杆18212、第三子导杆18213以及第四子导杆18214同时运动。第二连杆185仅带动第一子导杆18211和第二子导杆18212同时运动，第三连杆186仅带动第三子导杆18213和第四子导杆18214同时运动。
如图13、图15和图17所示，当第二连杆185沿第一方向(如逆时针方向)转动时，在第二连杆185的带动下，第一子导杆18211和第二子导杆18212分别带动第一子百叶18221和第二子百叶18222逆时针运动。当第二连杆185转动至与第一固定部1811贴合的位置时，第一子百叶18221和第二子百叶18222与第一固定部1811上的开口1815盖合，此时位于第一固定部1811上的第一子百叶18221和第二子百叶18222同时闭合。
当第二连杆185沿第二方向(如顺时针方向)转动时，在第二连杆185的带动下，第一子导杆18211和第二子导杆18212分别带动第一子百叶18221和第二子百叶18222顺时针运动。当第二连杆185转动至与第二固定部1812贴合的位置时，第一子百叶18221和第二子百叶18222与第一固定部1811呈最大角度，此时位于第一固定部1811上的第一子百叶18221和第二子百叶18222同时开启。
同样，如图18所示，当第三连杆186沿第一方向(如逆时针方向)转动时，在第三连杆186的带动下，第三子导杆18213和第四子导杆18214带动第三子百叶18223和第四子百叶18224逆时针运动。当第三连杆186转动至与第二固定部1812贴合时，第三子百叶18223和第四子百叶18224盖合于第二固定部1812的开口1815上，此时位于第二固定部1812上的第三子百叶18223和第四子百叶18224同时闭合。
当第三连杆186沿第二方向(如顺时针方向)转动时，在第三连杆186的带动下，第三子导杆18213和第四子导杆18214带动第三子百叶18223和第四子百叶18224顺时针运动。当第三连杆186转动至与第一固定部1811贴合时，第三子百叶18223和第四子百叶18224与第二固定部1812呈最大角度，此时位于第二固定部1812上的第三子百叶18223和第四子百叶18224同时开启。
如图20、图21所示，当第一转换组件101和第二转换组件102的第一子百叶18221和第二子百叶18222关闭且第三子百叶18223和第四子百叶18224开启时，室外风从室外进风口201经过第二换热腔232和室内送风口202到达室内，室内风从室内回风口203经过第一换热腔231和室外排风口204到达室外。当第一转换组件101和第二转换组件102的第一子百叶18221和第二子百叶18222开启且第三子百叶18223和第四子百叶18224关闭时，室外风从室外进风口201经过第一换热腔231和室内送风口202到达室内，室内风从室内回风口203经过第二换热腔232和室外排风口204到达室外。
采用双驱动装置结构设计，第二驱动装置1832和第三驱动装置1833分别控制第一固定部1811和第二固定部1812上的百叶1822非同步动作，也即，第二驱动装置1832(或第三驱动装置1833)将对应的百叶1822闭合后，第三驱动装置1833(或第二驱动装置1832)再运行控制百叶1822开启，可以保证第一转换组件101或第二转换组件102在切换状态的时候不会出现四个通道同时连通的情况，提高了新风机1000的密封性。
如图22所示，在一些实施例中，室内送风口202和室内回风口203位于第一转换组件101所在的一侧，室外进风口和室外排风口位于第二转换组件102所在的一侧。第一转换组件101的第一换热端口140与第二换热腔232连通，第一转换组件101的第二换热端口150与第一换热腔231连通。
在一些实施例中，新风机1000具有风量调节功能。如图23所示，第一转换组件101的转换主体110为圆筒状结构。第一转换组件101的进风端口120和出风端口130相对开设在圆筒状结构的圆柱面上，第一换热端口140和第二换热端口150开设在圆筒状结构的底面上。第一固定部1811或第二固定部1812可绕第一固定部1811和第二固定部1812交叉部1814所在的轴线转动，例如，第一固定部1811可绕第一固定部1811和第二固定部1812交叉部1814所在的轴线转动。
如图23、图24所示，隔挡部180还包括多个第一挡板18111和多个第二挡板18112，例如，隔挡部180包括两个第一挡板18111和两个第二挡板18112。两个第一挡板18111 相对设置，两个第二挡板18112相对设置。第一挡板18111和第二挡板18112位于第一转换组件101的底面上。
第一挡板18111与第一固定部1811相连接，第一挡板18111可以在第一固定部1811的带动下绕底面的圆心顺时针或逆时针转动。第二挡板18112与第二固定部1812相连接，第二挡板18112固定在底面上。两个第一挡板18111的面积大小可以与第二挡板18112在所述第一转换组件101的底面的正投影的面积大小相等。此时，所述第一转换组件101的底面上不再安装盖板，第一换热端口和第二换热端口的开度可变大或变小。
如图23所示，第一挡板18111与第一固定部1811连接的侧边为F，第二挡板18112与第二固定部1812连接的侧边为N，第二挡板18112的与侧边N相对的另一边为M。当第一固定部1811带动第一挡板18111按第一方向(如逆时针方向)转动第四预设角度时，第二换热端口150和第一换热端口140开度变小。当第一挡板18111转动至侧边F与第二挡板18112的侧边N抵接时或者第一挡板18111的与侧边F相对的另一边转动至与第一挡板18111的侧边M抵接时，开度最小。
当第一固定部1811带动第一挡板18111按第二方向(如顺时针方向)转动第五预设角度时，第一换热端口140和第二换热端口150的开度变大。当第一固定部1811转动至第二挡板18112的侧边M时，开度最大。
也即，当第一挡板18111在第一转换组件101或第二转换组件102底面的正投影与第二挡板18112重叠最多时，第一换热端口140和第二换热端口150的开度最大，当第一挡板18111在第一转换组件101或第二转换组件102底面的正投影与第二挡板18112重叠最少时，第二换热端口150和第一换热端口140的开度最小。
在一些实施例中，新风机1000具有控制室内微正压的功能。为了使室内保持微正压，需要新风量稍大于排风量，在排风电机转速不变的情况下，可通过减小排风气流所流经的端口的开度，以减小排风量。
如图25所示，新风机1000包括相互独立设置的两个档片，分别为第一档片18111A和第二档片18111B。第一档片18111A和第二档片18111B位于转换主体110的底面。第一档片18111A的侧边F1与第一固定部1811的上半部分(位于第三子腔1113的部分)连接，第二档片18111B的另一侧边F2与第一固定部1811的下半部分(位于第二子腔1112的部分)连接。驱动装置可以驱动第一档片18111A和第二档片18111B分别单独绕第一固定部1811和第二固定部1812交叉部1814所在的轴线转动。通过控制第一固定部1811的第一档片18111A和第二档片18111B分别独立转动，可以实现对新风气流和排风气流所流经的端口的开度分别进行独立调节。
本公开中新风机要实现微正压，可通过保持新风量不变，也就是保持进风气流所流经的端口的开度不变，减小排风气流所流经的端口的开度的方式实现。例如，根据所设风量，第一档片18111A和第二档片18111B先转动至预定位置，第二档片18111B再继续逆时针转动第六预设角度，使进入室风的风量稍大于排出室风的风量，实现室内微正压的效果。
如图26所示，新风机1000还包括压缩机330、四通阀340、第一换热器310、第二换热器320和电子膨胀阀350。依序连接的压缩机330、四通阀340、第一换热器310、电子膨胀阀350和第二换热器320组成冷媒回路，冷媒在所述冷媒回路中循环流动，通过第一换热器310与第二换热器320分别与空气进行换热，以实现新风机1000的制冷模式或制热模式。
压缩机330被配置为压缩冷媒以使得低压冷媒受压缩形成高压冷媒。
第一换热器310和第二换热器320被配置为将第一换热腔231中的空气与在第一换热器310中传输的冷媒进行热交换，或将第二换热腔232中的空气与在第二换热器320中传输的冷媒进行热交换。例如，第一换热器310在新风机1000的制冷模式下作为冷凝器进行工作，使得由压缩机330压缩的冷媒通过第一换热器310将热量散发至第一换热腔231中的空气而冷凝。第一换热器310在新风机1000的制热模式下作为蒸发器进行工作，使得减压后的冷媒通过第一换热器310吸收第一换热腔231中的空气的热量而蒸发。
在一些实施例中，第一换热器310和第二换热器320还包括换热翅片，以扩大空气与 第一换热器310中传输的冷媒之间的接触面积，从而提高第一换热腔231中的空气与冷媒之间的热交换效率。
电子膨胀阀350连接于第一换热器310与第二换热器320之间，由电子膨胀阀350的开度大小调节流经第一换热器310和第二换热器320的冷媒压力，以调节流通于第一换热器310和第二换热器320之间的冷媒流量。流通于室外换热器和室内换热器400之间的冷媒的流量和压力将影响室外换热器和室内换热器400的换热性能。膨胀阀205可以是电子阀。膨胀阀205的开度是可调节的，以控制流经膨胀阀205的冷媒的流量和压力。
四通阀340连接于所述冷媒回路内，四通阀340被配置为切换冷媒在冷媒回路中的流向以使新风机1000执行制冷模式或制热模式。
在一些实施例中，新风机1000还包括控制器190。控制器190与驱动装置和四通阀340耦接，控制器190被配置为：控制驱动装置来切换子腔之间的连通状态，和/或，控制四通阀340来切换第一换热器310和第二换热器320中冷媒流向，使得第一换热器310和第二换热器320的制热模式或制冷模式与新风机1000的运行模式相匹配。
控制器190通过控制第一转换组件101的四个子腔两两连通，进而能够将室外排风口204与第一换热腔231和第二换热腔232中的一个连通，室内送风口202与第一换热腔231和第二换热腔232中的另一个连通。
控制器190通过控制第二转换组件102的四个子腔两两连通，进而能够将室外进风口201与第一换热腔231和第二换热腔232中的一个连通，室内回风口203与第一换热腔231和第二换热腔232中的另一个连通。
新风机1000在开机、运行过程中用户手动控制切换，控制器190被动接收信号确定第一转换组件101和/或第二转换组件102需要换向时，或者控制器190通过接收检测信号确定第一转换组件101和/或第二转换组件102需要换向时，控制第一转换组件101和/或第二转换组件102换向。
以百叶式转换组件为例，控制器190控制第一转换组件101和/或第二转换组件102的控制方法可以为：确定新风机1000的运行模式以及当前各活动部182的多个百叶1822的开启状态，并判断当前各活动部182的多个百叶1822的开启状态与新风机1000的运行模式的匹配状态。
当匹配状态为不匹配时，控制器190控制相应的多个百叶1822转动，第一转换组件101或第二转换组件102进行换向。
控制器190控制第一转换组件101或第二转换组件102换向步骤可以包括步骤S11至步骤S13。
步骤S11，获取多个百叶1822的当前开度及百叶1822的目标开度。
步骤S12，根据多个百叶1822的当前开度及百叶1822的目标开度，确定相应的驱动装置的转动方向和转动角度。
步骤S13，根据确定的转动方向和转动角度控制驱动装置转动。
确定当前各活动部182的多个百叶1822的开度的方式可以为查询存储器中记录的各活动部182的多个百叶1822的开度。
在接收到停机信号之后，控制器190的控制方法还包括控制所有百叶1822复位的步骤，控制器190控制驱动装置将所有百叶1822转动至复位位置。例如，复位位置可以设置为第一子百叶18221和第二子百叶18222开启，第三子百叶18223和第四子百叶18224关闭，或第一子百叶18221和第二子百叶18222关闭，第三子百叶18223和第四子百叶18224开启。又或者第一子百叶18221、第二子百叶18222、第三子百叶18223和第四子百叶18224同时开启，或第一子百叶18221、第二子百叶18222、第三子百叶18223和第四子百叶18224同时关闭。
当再次开机时以复位位置作为当前各活动部182的百叶1822的当前位置。
所述步骤中驱动装置可以为第一驱动装置1831、第二驱动装置1832或第三驱动装置1833，第一驱动装置1831同时驱动第一固定部1811和第二固定部1812中的百叶1822，第二驱动装置1832和第三驱动装置1833分别对应驱动第一固定部1811和第二固定部1812 中的百叶1822。
控制器190调节进风气流所流经的端口的开度的控制方法包括步骤S21至步骤S23。步骤S21，获取目标风量和当前风量；
在步骤S21中，目标风量和当前风量可以通过风档变化以及风档变化量判断。风档变化量可能是由用户调节触发，也可以是控制器190自动调节。风档变化量可以是变大，也可以是变小。风档变化量是指由当前档位调大几档或者调小几档。
步骤S22，根据目标风量和当前风量确定驱动装置的转动方向和转动角度。
在步骤S22中，可以理解的是，当风量需要调大时，进风气流所流经的端口的开度需要进行调大。反之，当风量需要调小时，进风气流所流经的端口的开度需要进行调小。
确定驱动装置的转动方向和转动角度可以通过第一固定部1811的转动方向和转动角度确定。当各转换组件及各转换组件的内部结构已经确定时，第一固定部1811的转动方向、转动角度所对应的对端口的开度调节状态已经确定，因此，可通过风档变化量确定第一固定部1811的转动方向和转动角度。
步骤S23，根据确定的转动方向和转动角度控制驱动装置的转动方向和转动角度。
控制器190调节端口的开度的控制方法可以包括步骤S24至步骤S26。
步骤S24，获取多个第一挡板18111的目标位置以及多个第一挡板18111的当前位置。
步骤S25，根据多个第一挡板18111的目标位置以及多个第一挡板18111的当前位置，确定驱动装置的转动方向和转动角度。
步骤S26，根据确定的转动方向和转动角度，控制驱动装置转动。
例如，风量由最大档(如N4档)调到较小档(如N2档)，第一固定部1811及第一固定部1811的第一挡板18111沿第一方向(如逆时针方向)旋转设定角度，第一固定部1811达到预定位置，为了防止第一固定部1811在风压的作用下发生变化，限位功能启动。限位功能可通过限位隔挡170来实现，限位隔挡170可开启或关闭。例如，在第一固定部1811到达指定位置时，开启限位隔挡170，当第一固定部1811需要旋转时，关闭限位隔挡170。
当再次接到换向指令时，第一固定部1811限位解除，然后沿第二方向(如顺时针方向)转动到复位状态。接着与第一固定部1811对应的活动部182的百叶1822开启，与第二固定部1812对应的的百叶1822关闭，实现进风气流和排风气流所流经的换热腔的互换。
在一些实施例中，微正压模式下控制器190控制端口的开度的控制方法可以为确定与排风气流所流经的子腔，为待调节子腔。控制器190控制与位于待调节子腔中的第一固定部1811连接的第一档片18111A或第二档片18112B转动，转动方向为待调节子腔的第一档片18111A或第二档片18112B在盖板103上的正投影面积增大的方向，也即将排风气流所流经的端口的开度往调小的方向转动。
除此之外，还可以保持排风气流所流经的端口的开度不变，增加进风气流所流经的端口的开度实现微正压。
如下，以第一转换组件101的第一换热端口140与第一换热腔231连接，第一转换组件101的第二换热端口150与第二换热腔232连接，第二转换组件102的第一换热端口140与第一换热腔231连接，第二转换组件102的第二换热端口150与第二换热腔232连接为初始状态来说明新风机1000的一些运行模式，例如制冷模式，制热模式，除湿模式和加湿模式。
制冷模式时，进风气流流经蒸发器所在的换热腔，并且排风气流流经冷凝器所在的换热腔。
制热模式时，进风气流流经冷凝器所在的换热腔，并且排风气流流经蒸发器所在的换热腔。
除湿模式时，进风气流和排风气流流向与制冷模式相同，当吸附件吸收水分达到饱和后，冷媒流向、进风气流和排风气流流向同时切换。
加湿模式时，进风气流和排风气流流向与制热模式相同，当吸附件释放水分充分干燥后，冷媒流向、进风气流和排风气流流向同时切换。
<制冷模式>
如图27所示，控制器190控制四通阀340中冷媒流向，第一换热器310作为蒸发器，第二换热器320作为冷凝器。控制器190控制驱动装置将第二转换组件102的进风端口120与第一换热端口140连通，将第二转换组件102的第二换热端口150与出风端口130连通。
将第一转换组件101的进风端口120与第二换热端口150连通、将第一转换组件101的第一换热端口140与出风端口130连通。
进风气流的流通路径为：室外进风口201、进风端口120(室外)、第一换热端口140(室外)、第一换热腔231(蒸发器)、第一换热端口140(室内)、出风端口130(室内)、室内送风口202。室外进入室内的空气在该路径中向冷媒释放热量降温。
排风气流的流通路径为：室内回风口203、进风端口120(室内)、第二换热端口150(室内)、第二换热腔232(冷凝器)、第二换热端口150(室外)、出风端口130(室外)、室外排风口204。室内排放至室外的回风在该路径中吸收冷媒释放的热量升温。
<制热模式>
新风机1000的运行模式由制冷模式切换至制热模式具有两种实现方式，可单独改变冷媒流向，进风气流所经过的通道不变。或者单独切换进风气流流向，冷媒流向不变。本公开以冷媒流向不变为例进行说明。如图28所示，第一换热器310仍然作为蒸发器，第二换热器320作为冷凝器。控制器190控制将第二转换组件102的进风端口120与第二换热端口150连通、将第二转换组件102的第一换热端口140与出风端口130连通。
将第一转换组件101的进风端口120与第一换热端口140连通、将第一转换组件101的第二换热端口150与出风端口130连通。
进风气流的流通路径为：室外进风口201、进风端口120(室外)、第二换热端口150(室外)、第二换热腔232(冷凝器)、第二换热端口150(室内)、出风端口130(室内)、室内送风口202。室外进入室内的空气在该路径中吸收冷媒释放的热量升温。
排风气流的流通路径为：室内回风口203、进风端口120(室内)、第一换热端口140(室内)、第一换热腔231(蒸发器)、第一换热端口140(室外)、出风端口130(室外)、室外排风口204。室内排放至室外的回风在该路径中向冷媒释放热量降温。
吸附件500以块状、片状、网状包裹的颗粒等形式设置在第一换热器310和第二换热器320的表面。
吸附件500可以是分层放置方式或者以涂层的形式附在第一换热器310或第二换热器320的表面。
<除湿模式>
除湿模式时，进风气流流经蒸发器所在的换热腔，并且排风气流流经冷凝器所在的换热腔。也即，本模式下进风气流流向与制冷模式相同。本公开中仍以图1中所示的第一转换组件101的第一换热端口140与第一换热器310所在的第一换热腔231连通，第一转换组件101的第二换热端口150与第二换热器320所在的第二换热腔232连通，第一换热器310作为蒸发器，第二换热器320作为冷凝器为例进行说明。
第一换热器310(蒸发器)中的冷媒吸收空气中的热量，空气中的水分凝结成水珠，被蒸发器设置的吸附件500吸收，室外进入的风被干燥后输送到室内。第二换热器320(冷凝器)中的冷媒向周围空气中释放热量，冷凝器的吸附件500中的水分被蒸发，释放至空气中，并被排出至室外方向的气流带出至室外。
当第一换热器310(蒸发器)设置的吸附件500达到饱和时，同时第二换热器320(冷凝器)设置的吸附件500被烘干，如图29所示，控制器190通过控制第一转换组件101或第二转换组件102换向，使得进风气流经过第二换热腔232，排风气流经过第一换热腔231，同时控制器190控制冷媒换向，使得第二换热器320为蒸发器，第一换热器310为冷凝器。室外进入的风继续被第二换热器320的吸附件500除湿干燥后输送到室内。
<加湿模式>
加湿模式时，进风气流流经冷凝器所在的换热腔，并且排风气流流经蒸发器所在的换热腔。也即，本模式下进风气流流向与制热模式相同。本公开中仍以图28中所示的第一 换热器310作为蒸发器，第二换热器320作为冷凝器为例。控制器190控制将第二转换组件102的进风端口120与第二换热端口150连通、将第二转换组件102的第一换热端口140与出风端口130连通。
将第一转换组件101的进风端口120与第一换热端口140连通、将第一转换组件101的第二换热端口150与出风端口130连通。
当第二换热器320(冷凝器)的吸附件500被烘干时，丧失释放水分能力，此时控制器190控制第一转换组件101或第二转换组件102换向，使得进风气流流经第一换热腔231，同时第一换热器310切换作为冷凝器，由第一换热器310的吸附件500继续向新风中释放水分。
控制器190还被配置为获取吸附件500的吸附能力或者获取输入到室内的新风湿度，除湿模式中，当蒸发器的吸附件500的吸附能力下降或者输入到室内的新风湿度大于第一预设湿度时；或者，加湿模式中，当冷凝器的吸附件500的释放能力下降或者输入到室内的新风湿度小于第二预设湿度时，控制器190控制四通阀转换冷媒的流向，同时，控制器190控制第一转换组件101和第二转换组件102换向。第一预设湿度小于第二预设湿度。
获取吸附件500的吸附能力或者释放能力可通过进风气流连续经过同一换热腔的时长确定。进风气流连续经过同一换热腔的时间越长，该吸附件500的吸附能力或者释放能力越低。
本公开的新风机1000结构简单，制造成本低。同时控制器190的控制逻辑简单，实现方便。
在上述实施方式的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
本领域的技术人员将会理解，本发明的公开范围不限于上述具体实施例，并且可以在不脱离本公开的精神的情况下对实施例的某些要素进行修改和替换。本申请的范围收所附权力要求的限制。
