具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如图1所示，本发明提出了一种风道系统1，用以向一制冷间室提供冷气。所述风道系统1包括相互配合设置的干燥系统11和冷却系统12。
其中，所述冷却系统12具有蒸发器121、设置于所述蒸发器121两侧的回风口122和送风口123，所述干燥系统11设置于所述回风口122和所述蒸发器121之间，使得流向所述蒸发器121的空气干燥，从而避免结霜现象。
具体地，所述冷却系统12设有一冷却室15，所述蒸发器121设置于所述冷却室15内。 为避免漏冷，所述冷却室15通常由保温材料围成；本实施方式中，将所述干燥系统11设置于所述冷却室15外侧，并向冷却室15提供干燥后的空气，由此来减少冷却室15的占用空间，使得干燥系统11可以利用外部其他无需进行保温的空间。当然，作为本发明的另一较佳实施方式，也可将所述干燥系统11也设置于所述冷却室15内。
在本实施方式中，所述冷却室15具有用以连接干燥系统11的第一开口151和连通所述送风口123的第二开口152，所述第一开口151和第二开口152分别位于蒸发器121的两侧，使所述干燥系统11排出的干燥空气经所述第一开口151进入所述冷却室15，再流向所述蒸发器121后经所述第二开口152排出所述送风口123。
优选地，在本实施例中，所述风道系统1还包括设于所述第一开口151处的第一单向阀16、设于所述第二开口152或送风口123处的第二单向阀17；其中，所述第一单向阀16能够防止由所述干燥系统11排出的空气逆向流动，所述第二单向阀17能够防止由所述送风口123排出的空气逆向流动。
如图1和图2所示，所述干燥系统11包括相互连接设置的空压机111和储气罐112，使得经所述回风口122排出的空气依次经过所述空压机111、储气罐112后再流向所述蒸发器121。
具体地，所述空压机111从所述回风口122处抽气并压缩，降低水蒸气的饱和度，使得所述储气罐112中大部分水蒸气凝结成水，以使经过所述蒸发器121的空气干燥，避免了结霜现象，省去除霜过程，避免了负荷增大，效率低的问题。
其中，所述储气罐112的底部设有排水口1121和连接于所述排水口1121的排水阀1122，使得凝结的水经由所述排水阀1122排出外部。
为进一步保证干燥效果，本发明所述风道系统1还进一步设置有至少一个干燥模块13，所述干燥模块13设置于所述储气罐112与所述蒸发器121之间，以进一步对空气进行进一步干燥，更加保证排向蒸发器121的空气为干燥气体，避免蒸发器121结霜。
在本发明具体实施例中，如图1所示，所述干燥模块13设置有两个，其中一个靠近所述储气罐112设置，另一个靠近所述蒸发器121设置，使得空气自所述储气罐112排出后经过所述干燥模块13再流向所述蒸发器121，能够对空气进行进一步干燥。

此外，作为本发明的一较佳实施例，为方便安装等操作，所述干燥系统11设有一干燥间室18，将所述空压机111和所述储气罐112均设置于所述干燥间室18内，但是，所述干燥系统11依然通过管路或风道连接回风口122和空压机111、通过管路或风道连通干燥系统11和冷却室15。
当然，所述空压机111和所述储气罐112也可设置为开放式，这样便于所述空压机111散热。
如图2所示，本发明还提出一种具有如上述所述的任一风道系统1的制冷设备2，所述制冷设备2包括具有制冷间室22的箱体21，所述风道系统1设于箱体21上并用以向所述制冷间室22供冷，所述回风口122和送风口123设置于所述制冷间室22的内壁上，使得所述制冷间室22的空气由所述回风口122排出后，依次经过所述空压机111、储气罐112干燥后流向所述蒸发器121进行冷却，再由所述送风口123排出至所述制冷间室22中，从而使经过所述蒸发器121的空气干燥，从而避免了结霜现象，省去了除霜过程，提高制冷设备2的冷却效率。
所述制冷设备2还包括设于所述箱体21内的集水盒23，所述储气罐112的排水口1121与所述集水盒23相连接，能够避免水流至外部引起安全隐患，同时能够提高制冷设备2的散热效率。
综上所述，本发明中的风道系统1及具有其的制冷设备2，通过相互配合设置的干燥系统11和冷却系统12，使得经所述回风口122排出的空气依次经过所述空压机111、储气罐112后再流向所述蒸发器121，以使经过所述蒸发器121的空气干燥，避免了结霜现象，省去了除霜过程，避免了负荷增大，效率低的问题。
以上所述的仅是本发明的优选实施方式，应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
