Description

具有加湿功能的高效节能中央空调风拒
技术领域
本发明涉及一种空调风拒， 更具体地涉及一种具有加湿功能的节能高效节能中 央空调风拒。 背景技术 现在的中央空调风拒分为两类， 一类是带有电热加湿器的可控湿度空调风拒， 另一类是不带加湿器的普通空调风拒。 近几年出现的湿帘型环保空调也有广泛的应 用， 在一些对温度和湿度要求不高的场合部分代替了中央空调风拒。 普通空调风拒主要包括以下几大部分： 风拒主体； 在风拒主体外部配备的主要 风口： a) 配备在风拒主体前端的送风口； b)后端的回风口； 以及 c)后上端的新风口； 在回风管上一般会接旁路抽风管带排风机； 在风拒主体内部从前向后依此配备着风 机、 水冷盘管和多级空气过滤网。 普通中央空调风拒可满足各种对温度控制比较精 确的场合，适应性强，使温度不随天气的变化而变化，通过水冷盘管可除湿，但耗能 较高不能加湿， 且湿度会随着天气的变化而变化。 可控湿度空调风拒和普通空调风拒的区别主要在于： 1 , 在风机前段加装一个电 加热加湿器； 2, 在回风管上加装湿度探测仪； 3 , 在送风管加装电加热器。 可控湿 度空调风拒可满足各种对温度和湿度控制要求都比较精确的场合，适应性强， 即可 通过水冷盘管除湿，也可用电加湿器加湿； 温度、 湿度都不随天气的变化而变化，但 耗能很高而且耗水， 尤其在干燥天气，耗能更高。
湿帘型环保空调是一种新型的简单廉价的空气降温技术： 湿帘型环保空调由湿 帘、 风机和供水系统组成。 其降温原理是： 供水系统提供湿帘需要的水分， 当风机 运行时在湿帘两边产生压差， 使空气流过多孔湿润的湿帘。 内控表面上的水在绝热 状态下蒸发， 又被流经湿帘的空气带走， 同时带走了大量的热量， 从而降低了空气 自身的温度。 湿帘型环保空调节能效果有非常显著的降温效果， 理想，但是受天气的 影响很大，适应性差， 不能保持相对稳定的温度和湿度；其只能连续加湿，不能除湿， 湿度不可控， 耗水量大， 在阴雨高湿度天气不起作用； 且降温后的空气湿度太大， 并不适合直接用于人类的生活可活动空间的温度调节。 因此， 有必要提供一种改进的具有加湿功能的高效节能中央空调风拒来克服上 述缺陷。
发明内容
本发明的目的是提供一种具有加湿功能的高效节能中央空调风拒，结构简单、耗 能低耗水量少、 节约能源且可控温、 可加湿和除湿， 适合直接用于人类的生活可活 动空间的温度调节。

较佳地， 所述新风口、 送风口和回风口均设有风阀， 所述风拒主体靠近回风口设 有与所述温湿度控制装置电连接的温湿度传感器， 所述温湿度控制装置接收所述温 湿度传感器的传递的信息并控制所述供水系统的供水水量和风阀的开口度， 进而控 制风量和空气温湿度。
较佳地， 还包括紫外线杀菌模块， 所述紫外线杀菌模块设置于所述送风机和送 风口之间。
较佳地， 还包括多个水雾化喷头， 所述多个水雾化喷头设置于所述冷凝盘管的 后端且与所述水泵连通， 所述多个水雾化喷头与所述水泵之间设有电磁阀， 所述电 磁阀与所述温湿度控制装置电连接。

图 1〜图 3显示了本发明具有加湿功能的高效节能中央空调风拒的一优选实施例。 首先， 请参考图 1和图 2, 本发明具有加湿功能的高效节能中央空调风拒包括风拒主 体 10, 所述风拒主体 10呈中空结构。 所述风拒主体 10的前端 101设有送风口 11 , 所述风拒主体 10的后端 102设有回风口 12。 位于所述风拒主体 10内部并从所述风 拒主体 10的前端 101到后端 102依次设有送风机 20、 冷凝盘管 30、 初级空气过滤 网 41及次级空气过滤网 42,所述送风机 20和冷凝盘管 30还与一温湿度控制装置电 (图未示)连接， 所述温湿度控制装置控制所述送风机 20和冷凝盘管 30工作。 所述风 拒主体 10上位于所述冷凝盘管 30前方还设有新风口 13 ,所述风拒主体 10的外部正 对所述新风口 13设有湿帘预冷装置 50,所述湿帘预冷装置 50通过所述新风口 13与 所述风拒主体 10的内部导通。 在所述送风机 20的作用下， 所述风拒主体 10外的新 风先通过所述湿帘预冷装置 50预冷后才进入所述风拒主体 10内部。 而同时， 从所 述回风口 12进入的回风空气先通过所述初级空气过滤网 41及次级空气过滤网 42过 滤后， 再经过所述冷凝盘管 30冷却后进入所述风拒主体 10 内部。 进入所述风拒主 体 10内部的新风和回风空气进行混合后从所述送风口 11送出。
请参考图 2及图 3 , 所述湿帘预冷装置 50具体包括设有开口的壳体 51、 连接于 壳体 51内部四周的多个湿帘 52、正对所述湿帘 52的蒸发控制系统 53及与所述湿帘 52连通的供水系统 54, 所述供水系统 54与所述控制装置 (图未示） 电连接， 所述 控制装置用于控制所述供水系统 54的启闭。 所述多个湿帘 52正对所述壳体 51的开 口， 且每一所述湿帘 52外形呈板状、 由蜂窝状的亲水疏松物质构成， 所述湿帘 52 上设有多个小孔， 工作时， 所述供水系统 54在控制装置的作用下向所述湿帘 52提 供的水沿所述小孔渗透使整个湿帘 52湿润， 湿帘 52上的水在所述蒸发控制系统 53 的作用下被蒸发成水蒸气。 在送风机 20的作用下， 高温的空气从所述湿帘预冷装置 50的开口一端进入湿帘 52并穿过所述小孔时， 带走所述湿帘 52内的水蒸气， 使所 述湿帘 52内的水分不断蒸发补充， 由于水分蒸发需要从空气中吸收大量的热量， 因 此经过湿帘 52的空气会被加湿降温。 被加湿降温后的空气通过所述新风口 13进入 所述风拒主体 10内部。
所述供水系统 54包括水箱 541和置于所述水箱 541内的水泵 542,所述水泵 542 与所述湿帘预冷装置 50的湿帘 52连通且用于将所述水箱 541 内的水提到所述湿帘 52的上侧淋下以湿润所述湿帘 52。 所述风拒主体 10上正对所述冷凝盘管 30的冷凝 水出水口设有排放口 （图未示）， 所述湿帘预冷装置 50的水箱 541与所述排放口连 通， 经过所述冷凝盘管 30产生的冷凝水通过所述排放口回收到所述水箱 541中供所 述湿帘预冷装置 50作为水源使用以实现循环使用。 另外， 所述水箱 541还外接自来 水管 543以作为水源的补充。
另外， 所述风拒主体 10上设置的新风口 13设有新风阀， 所述送风口 11设有送 风阀及所述回风口 12设有回风阀， 所述风拒主体 10靠近回风口 12设有与所述温湿 度控制装置电连接的温湿度传感器（图未示）， 所述温湿度控制装置接收所述温湿度 传感器的传递的信息并控制所述供水系统 54的供水水量和新风阀、 送风阀及回风阀 的开口度， 进而控制风量和空气温湿度。
请参考图 1〜图 3 , 下面具体描述本发明具有加湿功能的中央空调风拒的具体工 作过程。 所述控制装置控制所述送风机 20启动时， 风拒主体 10内外 （尤其湿帘预 冷装置 50两边）产生压差， 使风拒主体 10外的高温空气流过多孔湿润的湿帘 52, 经过所述湿帘 52加湿降温后的空气通过所述新风口 13进入所述风拒主体 10内部， 而同时， 从所述回风口 12进入的回风空气先通过所述初级空气过滤网 41及次级空 气过滤网 42过滤后， 再经过所述冷凝盘管 30冷却后进入所述风拒主体 10内部； 进 入所述风拒主体 10 内部的新风和回风空气进行混合后从所述送风口 11送出。 而经 过所述冷凝盘管 30冷却后产生的冷凝水回收到所述水箱 541中供所述湿帘预冷装置 使用以实现循环使用。 参考图 4,为本发明具有加湿功能的高效节能中央空调风拒的另一实施例的结构 示意图。 本实施例的高效节能中央空调风拒与第一实施例不同的是： （1 )还包括紫 外线杀菌模块 60, 所述紫外线杀菌模块 60设置于所述送风机 20和送风口 11之间， 用于杀菌； （2 )还包括多个水雾化喷头 70, 所述多个水雾化喷头 70设置于所述冷凝
一支通向湿帘预冷装置 50的湿帘 52 , 另一支通向所述水雾化喷头 70 ), 所述水雾 化喷头 70与所述水泵 542之间设有电磁阀 （图未示）， 所述电磁阀与所述温湿度控 制装置电连接， 本实施例的高效节能中央空调风拒进行冬季模式时候水雾化喷头 70 工作控制湿度， 湿帘预冷装置 50停止工作； 其它模式湿帘预冷装置 50工作控制湿 度， 水雾化喷头 70停止工作。
参考图 5 ,为本发明具有加湿功能的高效节能中央空调风拒的第三实施例的结构 示意图。 本实施例的高效节能中央空调风拒与第一实施例不同的是： 本实施例还包 括抽风口 14和排风机 80, 所述抽风口 14设置于所述多级空气过滤网 （41、 42 ) 的 后端， 而所述抽风机 80置于所述抽风口 14及所述回风口 12之间， 且所述抽风机 14 与所述温湿度控制装置电连接， 且所述抽风口 14设有抽风阀 （图未示）， 所述温湿 度控制装置控制所述抽风阀的开口度。 本实施例的高效节能中央空调风拒的温湿度 控制装置根据使用环境不同， 可设定夏季制冷模式， 春秋季制冷模式和冬季制热模 式等多种运行模式。
参考图 6,为本发明具有加湿功能的高效节能中央空调风拒的第四实施例的结构 示意图。 本实施例的高效节能中央空调风拒与第二实施例不同的是： 本实施例还包 括与所述回风口 12连接的回风管 120及与所述回风管 120连通的抽风管 150, 所述 抽风管 150设有抽风口 15和正对所述抽风口 15的抽风机 90,且所述抽风机 90与所 述温湿度控制装置电连接， 且所述抽风口 15设有抽风阀 151 , 所述温湿度控制装置 控制所述抽风阀 151 的开口度。 可见， 本实施例与第三实施例的不同之处仅在于抽 风口和排风机设置的位置不同， 但也能实现同样的抽风目的。 本实施例的高效节能 中央空调风拒的温湿度控制装置根据使用环境不同， 可设定夏季制冷模式， 春秋季 制冷模式和冬季制热模式等多种运行模式。
下面，结合四个实施例，具体描述本发明具有加湿功能的高效节能中央空调风拒 的优点： 本发明具有加湿功能的高效节能中央空调风拒结合了普通中央空调风拒温 度控精确、 可除湿、 适应性强、 不受天气影响的优点和湿帘环保空调节能高效、 可 加湿的优点， 可实现可控湿度空调风拒的所有功能， 但又避免了其高耗能耗水的不 足； 且风拒产生的大量冷凝水可直接作为湿帘的水源实现循环使用， 高效环保， 温 度湿度控制准确。 这样， 在夏季新风经过湿帘预冷装置降温后进入风拒， 比直接由 新风阀进入风拒节能。 春秋季釆用春秋季模式全部换新风， 新风由停水湿帘预冷装 置机进入风拒后进入车间由抽风管经抽风机直接外排保持原节能状态， 新风通过正 常运新的湿帘预冷装置降温后再进入车间通过抽风系统外排； 冬季釆用冬季模式， 水管中的冷冻水转换成由锅炉或蒸汽加热后的热水， 水帘机构供水电磁阀关闭， 水 帘停止运行， 新风风门开度保持固定设定位置， 以保证满足新风要求， 加湿由高压 水泵加压自来水经水雾化喷头喷雾控制湿度。
根据南方和北方气候不同， 夏季、 春秋冬季的模式也不相同， 准确来说： 1 ) 当 气温超过 25摄氏度时， 使用夏季模式， 新风阀小部分打开， 回风阀全开， 抽风阀全 关， 湿帘预冷装置 50只冷却进入风拒的新风， 即主要由冷凝盘管 30中的冷却水冷 却空气降温； 2)当气温在 10〜25摄氏度时， 使用春秋季模式， 新风阀全开， 回风阀全 关， 抽风阀打开， 抽风机运行， 冷却管盘 30中没有冷却水， 完全由湿帘预冷装置 50 制冷； 3 ) 当温度低于 10摄氏度时， 使用冬季模式， 湿帘预冷装置 50停水， 新风阀 小部分打开， 回风阀全开， 抽风阀全关， 冷却管盘 30中的冷却水换成了热水， 水雾 化喷头 70根据湿度大小喷雾加湿。
以上结合最佳实施例对本发明进行了描述， 但本发明并不局限于以上揭示的实 施例， 而应当涵盖各种根据本发明的本质进行的修改、 等效组合。
