Description
技术领域
本发明涉及一种全新风除湿机组,具体涉及一种带热回收全新风低温除湿机。
背景技术
目前,全新风除湿机组在低温环境下容易结霜,影响机组的除湿能力;为防止结霜严重影响机组运行,还需要另外配置除霜装置。且室内排风的热量直接排向室外环境,造成能量浪费。该发明就提供了一种带热回收全新风低温除湿机,利用室内排风中热量对室外新风进行预热,提高进入除湿机空气的温度,使湿空气在蒸发器被冷却时不至于结霜,使机组满足低温环境下的使用要求。
发明内容
本发明的目的在于提供了一种带热回收全新风低温除湿机,可满足低温环境下的使用要求,解决了以往全新风除湿机组在低温环境下结霜以及室内排风热量浪费等问题。
本发明是这样来实现的,一种带热回收全新风低温除湿机,主要包括室外新风温湿度传感器、排风风机、热回收换热器、室内排风温湿度传感器、翅片蒸发器、分液头、膨胀阀、干燥过滤器、贮液器、翅片冷凝器、压缩机、新风风机和控制器;其特征在于:所述压缩机连接翅片冷凝器,翅片冷凝器连接贮液器,贮液器连接干燥过滤器,干燥过滤器连接膨胀阀,膨胀阀连接分液头,分液头连接翅片蒸发器,翅片蒸发器连接压缩机;所述室外新风温湿度传感器和室内排风温湿度传感器分别设置在室外进风口和室内排风口位置,室外进风口和室内排风口位置旁边设有热回收换热器,热回收换热器设置在排风风机和翅片蒸发器一侧,所述新风风机设置在翅片冷凝器一侧;所述室外新风温湿度传感器、排风风机、室内排风温湿度传感器、压缩机、新风风机分别和控制器连接。
本发明的工作原理为:由压缩机排出的高温高压蒸汽经翅片冷凝器冷凝,翅片冷凝器依次连接贮液器、干燥过滤器、膨胀阀、分液头、翅片蒸发器,经翅片蒸发器蒸发后回到压缩机;室内排风和室外新风在热回收换热器里分别呈正交叉方式流经换热器芯体,由于气流分隔板两侧气流存在着温差,两股气流通过分隔板时呈现传热现象,引起热交换过程。当室外温度较低时,室外新风从室内排风中获得热量,使温度升高,室外新风从室内排风中回收能量。室外新风经热回收换热器升温后,通过蒸发器被冷却后,温度降低至露点温度以下,析出凝结水,使空气的含湿量降低,然后通过风冷冷凝器,湿空气被等湿加热后通过风机排出,排出的空气温度升高,相对湿度降低。
机组运行时,压缩机排出的高压制冷剂气体经风冷冷凝器冷凝后依次经过贮液器、干燥过滤器,再经过热力膨胀阀节流后进入蒸发器,在蒸发器中,吸收外部空气热量蒸发变成低压的制冷剂蒸汽,制冷剂蒸汽通过气液分离器后,再被压缩机吸入进行压缩,从而完成了一个制冷循环。
室内排风和室外新风在热回收换热器里分别呈正交叉方式流经换热器芯体,由于气流分隔板两侧气流存在着温差,两股气流通过分隔板时呈现传热现象,引起热交换过程。当室外温度较低时,室外新风从室内排风中获得热量,使温度升高,室外新风从室内排风中回收能量。室外新空气经热回收交换器预热后,通过蒸发器被冷却后,温度降低至露点温度以下,析出凝结水,使空气的含湿量降低,然后通过风冷冷凝器,湿空气被等湿加热后通过风机排出,排出的空气温度升高,相对湿度降低,从而达到除湿效果。
本发明的技术效果在于,提供了一种带热回收全新风低温除湿机,可满足低温环境下的使用要求,解决了以往全新风除湿机组在低温环境下结霜以及室内排风热量浪费等问题。
