如图1所示，为本发明提供的一种无水加湿空调，包括制冷剂回路，所述制冷剂回路包括通过管路连接的压缩机3、室内换热器13、节流装置7和室外换热器2，其中，所述压缩机3通过换向阀4分别与室内换热器13及室外换热器2连接，用于切换制冷剂流向，所述室内换热器13设于室内机5中，所述室外换热器2设于室外机1中，其还包括加湿模块22和为所述加湿模块22供风的加湿风机10，所述加湿模块22设有依次连通的进风口、吸湿材料室23和出风口，所述吸湿材料室23设有风道20，所述风道20的侧壁设有吸湿材料12，可以利用吸湿材料12吸收空气中的水分为加湿模块22蓄水，所述出风口通 过加湿管路8连接到所述室内机5中；所述压缩机3的出口管路与入口管路之间并联有加热管11，所述加热管11插入所述吸湿材料12中，用于可选择性地加热所述吸湿材料12，此处可选择性地加热表示，在加湿模块22吸湿过程中，加热管19不加热，在加湿模块22加湿过程中，加热管19加热；当需要加湿时，加热管11开启加热吸湿材料12，使吸湿材料12中的水分解吸，室外空气进入吸湿材料室23吸收吸湿材料12解吸的水分，使室外空气的湿度增加，加湿管路8与室内机5中的贯流风扇6处相接，贯流风扇6连接处设置了加湿口，加湿后的空气通过加湿口后在贯流风扇6作用下送入房间实现加湿功能。
下面通过三个具体实施例说明本发明的内容：
实施例1
为了使得加湿模块22具有更优的吸湿效果，如图2和图4所示，优选地，所述室外换热器2与所述节流装置7之间的管路可以串联有冷凝器24；在空调制热过程中，经过节流装置7的低温低压制冷剂液体流入冷凝器24中，所述冷凝器24插入所述吸湿材料室23中，且所述冷凝器24至少有部分外露于所述风道20中，优选地，冷凝器24沿径向一半埋在吸湿材料12中，一半裸露在风道20中，由于冷凝器24的表面温度很低，当有空气吹过冷凝器24表面时，会产生凝露现象，凝结为冷凝水，并排入吸湿材料12中，吸湿材料12吸收水分。
为了方便在吸湿模式下将经过吸湿材料室23的多余空气排出，还可以包括排气管路21，所述排气管路21与所述加湿管路8连接，并在连接处设有切换阀16，用于择一导通所述加湿管路8和排气管路21；即在加湿模块22吸湿过程中，切换阀16导通排气管路21，多余空气从排气管路21排出室外，在加湿模块22加湿过程中，切换阀16导通加湿管路8，加湿后的空气从加湿管路8进入室内机5。此处切换阀16优选采用电机切换阀，通过小型电机驱动挡板来实现模式切换，与电子风阀相比成本大大减小。
为了使得进入加湿模块22中的室外空气有一个过渡的流动空间， 所述进风口与所述吸湿材料室23之间设有引风室19，所述加湿风机10设于所述进风口与所述引风室19之间，所述加湿风机10可以设于进风口外、进风口内或出风口处，当设于出风口处时，加湿风机10为负压风机，用于将室外空气抽吸进吸湿材料室23，优选地，所述加湿风机10设于所述进风口与所述加热室19之间，设置方便，可操作性强；所述加湿风机10优选具有2个调速档位，能实现高风档与低风档切换，在加湿过程中，风机开低风档，低风档风量可以取30～50m3/h；在吸湿过程中，风机开高风档，高风档风量可以取300～350m3/h。
为了防止杂质进入加湿模块22，所述进风口处可以设有过滤网18。
为了增大加热管11与吸湿材料12的接触面积，使得在加热时能够充分加热吸湿材料12，优选地，所述加热管11呈蛇形迂回设置于所述吸湿材料12中。
为了方便调节流量以及管路的开闭，所述加热管11的入口管和出口管上可以分别设有调节阀，表示为25、26，所述调节阀25、26优选为电磁膨胀阀，性能优良，可靠性高。
为了避免外界空气遇到低温的冷凝器而产生冷凝水滴落到室外机1，所述冷凝器24外露出所述加湿模块22的部分套设有保温管17，以对该冷凝器外露部分14起到保温作用。
有利地，所述加湿模块22可以通过固定器15固定在所述室外机1上，安装固定方便，另外，通常室外机1内设有室外机风机9。
为了方便形成所述风道20，如图2所示，所述吸湿材料室23内位于所述吸湿材料12的上方留有空间，可以采用所述吸湿材料12不填满吸湿材料室23，该空间形成所述风道20。
实施例2
本实施例与实施例1的区别在于：如图3和图4所示，所述室外换热器2与所述节流装置7之间的管路可以并联冷凝器24，通过调节阀27调节流入冷凝器24的制冷剂液体流量，或用于开闭所述冷凝器24。
实施例3
本发明还提供了一种利用上述所述的无水加湿空调的加湿方法，其包括吸湿控制模式和加湿控制模式；
所述吸湿控制模式包括：
可以先将加湿风机10设置为高风档，切换阀16切换至导通排气管路21，调节阀25、26均关闭，保持加热管11关闭(即不加热)，室外空气从进风口进入吸湿材料室23，吸湿材料12吸收空气中的水分，进一步地，可以利用冷凝器24与室外空气进行热交换，对室外空气进行冷凝，冷凝水由吸湿材料12吸收；吸湿过程持续一段时间后，加湿风机10停止，切换阀16切换至导通加湿管路8；
所述加湿控制模式包括：
获取房间湿度；
当房间湿度低于设定湿度值时，加湿风机10开启并设置为低风档，调节阀25、26均打开，加热管11开启加热吸湿材料12，使吸湿材料12中的水分解吸，室外空气由风道20进入吸湿材料室23吸收吸湿材料12解吸的水分，使室外空气的湿度增加；
由加湿风机10将加湿后的室外空气送入室内机5；加湿后的空气在贯流风扇6低压区与回风混合，送入房间以提高空气湿度。
由以上实施例可以看出，本发明结构简单，可靠性高，能在空调制热中对房间湿度进行有效控制，可以在冬季房间空气干燥时对房间加湿，且能实现恒温加湿，保证房间空气处于合理的湿度范围。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
工业实用性
