Description
技术领域
本发明涉及空调与制冷技术领域,具体涉及一种恒温恒湿节能空气处理机组及其控制方法。
背景技术
在温度较高、湿度较大的南方地区,都对能够调节室内温度和湿度的恒温恒湿空调需求较大。
传统空调通常设置有表冷盘管,但没有设置再加热管,因此,在炎热的夏季不能有效调节室内湿度,且降温除湿后的空气温度过低容易造成风口结露、舒适度不佳的问题。因此,一般需要对降温除湿后的空气需要再加热处理,以达到设定的送风温度,而现有恒温恒湿空调通常用电加热或锅炉电器等作为加热热源,造成额外的能耗。
发明内容
本发明针对现有技术中的上述不足,提供了一种能够解决现有技术中恒温恒湿空调在对降温除湿后空气再加热的能耗较高的问题的恒温恒湿节能空气处理机组及其控制方法。
为解决上述技术问题,本发明采用了下列技术方案:
提供了一种恒温恒湿节能空气处理机组,其包括外壳,外壳上分别设置有回风口、新风口和送风口,外壳内设置有换热管,换热管内包括蒸发管段和冷凝管段,蒸发管段的一端与新风管连接,新风管的一端与外壳上的新风口连接,蒸发管段的另一端与混合管连接,混合管的侧壁与外壳上的回风口连接,混合管的另一端与表冷管连接,混合管与表冷管的连接部设置有表冷器,表冷管的端部与冷凝管段连接,冷凝管段的另一端与送风管连接,送风管与外壳上的送风口连接。
上述技术方案中,优选的,送风管内设置有电辅热器。
上述技术方案中,优选的,新风管与混合管间通过调节管相互连接。
上述技术方案中,优选的,调节管上设置有调节阀。
上述技术方案中,优选的,送风管和混合管内均设置有温度传感器。
上述技术方案中,优选的,外壳内设置有控制器,温度传感器、调节阀分别与控制器电连接。
本发明提供的上述恒温恒湿节能空气处理机组的主要有益效果在于:
本发明通过设置混合管和新风口,从而将新风通过换热管的蒸发管段换热,使换热管升温,而使换热后的新风温度下降,然后与温度较低的回风混合,从而实现对回风进行再加热,然后将混合气体经过表冷器降温处理,并再次经过冷凝管段换热再次升温,从而能将满足送风温度需求的空气从送风口排出。
通过室外新风经过换热管换热后,与回风混合,从而利用室外新风作为再热热源,省去一般的再热热源,同时室外新风换热后的温度降低,从而降低新风处理能耗,新风和回风混合后在通过表冷器进行降温除湿,再经过换热管的冷凝管段进行再热后,能达到设定的送风温度,相对于现有技术中通过热源加热,换热器换热能有效节省能源,不必再进一步调节温度,提高了能源利用效率,并能提高人体舒适度。
在室外温度较低时,通过设置电辅热器,通过电辅热器对降温除湿后的回风与新风混合空气进行再加热,从而有效保证送风温度,同时由于电辅热器不需要直接将回风加热到送风温度,而是通过与新风混合换热,当进入送风管的温度未达到设定温度时,再补充加热,因此其能耗相对于现有结构也更小,能源利用效率也更高。
通过设置调节阀和调节管,当室外温度较高,进入送风管的混合气体温度仍高于设定温度时,可通过打开调节阀,使调节管将新风绕过换热管,直接通入混合管中,与回风直接混合,跳过换热管对混合气体再次加热的步骤,以降低送风温度,从而最大限度利用气体自身热量,最大限度提高能源利用效率。
附图说明
图1是本发明的结构示意图。
其中,1、外壳,11、回风口,12、新风口,13、送风口,2、新风管,3、换热管,31、蒸发管段,32、冷凝管段,4、混合管,41、调节管,42、调节阀,43、温度传感器,44、控制器,5、表冷管,51、表冷器,6、送风管,61、电辅热器。
具体实施方式
下面结合附图对本发明作进一步说明:
如图1所示,其为恒温恒湿节能空气处理机组的结构示意图。
本发明的恒温恒湿节能空气处理机组包括外壳1,外壳1上分别设置有回风口11、新风口12和送风口13,三个开口分别位于外壳1上的不同方向,以避免相互干扰。
外壳1内设置有换热管3,通过换热管3以实现对新风和混合空气换热除湿。换热管3内包括蒸发管段31和冷凝管段32,蒸发管段31的一端与新风管2连接,回风口11与外壳1上的新风管2连接,蒸发管段31的另一端与混合管4连接,从而与新风换热,对新风降温,并将换热管3的温度升高,并将换热后的新风送入混合管4;混合管4的侧壁与外壳1上的回风口11连接,从而将回风与新风混合。通过对新风换热,实现对换热管3的加热,再与回风混合,能有效实现预升温作用,避免额外设置加热源,消耗额外能量。
混合管4的另一端与表冷管5连接,混合管4与表冷管5的连接部设置有表冷器51,表冷管5的端部与冷凝管段32连接,冷凝管段32的另一端与送风管6连接,通过表冷器51以对混合空气进行降温除湿,再通过冷凝管段32对混合空气加热升温,送风管6与外壳1上的送风口13连接,以将处理后的空气送出。
优选的,送风口13内设置有电辅热器61。当室外温度较低时,通过电辅热器61对混合气体进行加热处理,以保证送出的空气到达设定温度。
新风管2与混合管4间设置有相互连接的调节管41。调节管41上设置有调节阀42。当室外温度较高时,通过调节管41将新风绕过换热管3直接送入混合管4中,并与回风混合,避免对换热管3过度加热,从而减弱冷凝管段32对混合气体的再加热作用,以降低送风温度,从而最大限度利用气体自身热量,最大限度提高能源利用效率。
送风口13和混合管4内均设置有温度传感器43,以监测混合空气和送风管6中空气的温度,当混合空气温度较高时,即打开调节阀42,将新风管2与混合管4直接连通。
外壳1内设置有控制器44,温度传感器43、调节阀42、电辅热器61分别与控制器44电连接。控制器44为单片机。通过控制器44,调节各部件工作,以适应不同工况。
下面是本方案的工作过程说明:
新风从新风口12进入新风管2,并通过换热管3的蒸发管段31换热,使新风温度下降,换热器的换热管3温度上升,再进入混合管4,并与回风口11进入的回风混合,将混合气体经过表冷器51降温除湿处理后,并再次经过冷凝管段32换热升温,从而能将满足送风温度需求的空气从送风口13排出。
上面对本发明的具体实施方式进行描述,以便于本技术领域的技术人员理解本发明,但应该清楚,本发明不限于具体实施方式的范围,对本技术领域的普通技术人员来讲,只要各种变化在所附的权利要求限定和确定的本发明的精神和范围内,这些变化是显而易见的,一切利用本发明构思的发明创造均在保护之列。
