Description
技术领域
本发明涉及一种低温除湿机,具体为一种可调节除霜量的低温除湿机。
背景技术
目前,除湿机组的低温除霜往往是通过停止压缩机的运行,利用风机通风除霜,这样易造成压缩机的频繁启动、机组除湿能力下降的情况产生,且由于受环境温度的影响,容易造成除霜不彻底,影响机组运行。该发明就提供了一种可调节除霜量的低温除湿机,可在不同环境温度的情况下,根据翅片蒸发器的实际温度,利用流量调节阀调节旁通路的流量大小,使机组满足不同环境温度下的除霜要求。
发明内容
本发明的目的在于提供了一种可调节除霜量的低温除湿机,可在不同环境温度的情况下,根据翅片蒸发器的实际温度,利用流量调节阀调节旁通路的流量大小,使机组满足不同环境温度下的除霜要求。解决了以往除湿机组除霜需停压缩机以及环境温度变化时除霜不彻底、除霜时间长等问题。
本发明是这样来实现的,一种可调节除霜量的低温除湿机,包括温湿度传感器、翅片蒸发器、翅片冷凝器、流量调节阀、分液头、膨胀阀、贮液器、压缩机、干燥过滤器、离心风机、控制器,其特征是:由压缩机排出的高温高压蒸汽,一路连接翅片冷凝器,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;另一旁通路经流量调节阀,再进入翅片蒸发器;经翅片蒸发器蒸发后回到压缩机;所述除霜温度传感器安装在翅片蒸发器上,湿空气通过翅片蒸发器被冷却后,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,然后通过翅片冷凝器,湿空气被等湿加热后通过离心风机排出,排出的空气温度升高,相对湿度降低;温湿度传感器、除霜温度传感器、压缩机、离心风机、流量调节阀都连接到控制器。
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。
湿空气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。
当达到除霜条件时,旁通路流量调节阀开启,压缩机排气端高温制冷剂气体通过旁通路进入蒸发器与蒸发器内两相制冷剂混合,在压缩机的连续抽吸过程中,混合后的制冷剂分散到蒸发器盘管内部通道,将热量排放至霜层,起到除霜作用,流量调节阀还可根据翅片结霜程度自动调节旁通路流量的大小,满足除霜的要求。
本发明的技术效果在于,提供了一种可调节除霜量的低温除湿机,可在不同环境温度的情况下,根据翅片蒸发器的实际温度,利用流量调节阀调节旁通路的流量大小,使机组满足不同环境温度下的除霜要求。
