Description
技术领域
本发明涉及能源设备领域,特别涉及一种转轮除湿用热泵再生系统。
背景技术
近年来,我国加强了对能耗强度和碳排放指标的考核,从而引发地方政府对“双高”企业的限电和限产。而国家借此优化了电价机制,完善了能源供应结构,并且有助于达成“双碳”目标。而在此背景下,保证充足能源利用效率成为高能耗企业发展中必不可少的部分。
而现如今,很多设备和系统,比如电加热除湿系统,其能源利用效率因为各种原因往往难以满足需求,因此对其进行能源优化方面的改造势在必行。
发明内容
为解决上述问题,本发明提供了一种转轮除湿用热泵再生系统。
根据本发明的一个方面,提供了一种转轮除湿用热泵再生系统,包括压缩机、冷凝器、膨胀阀、蒸发器和电加热器,其中,所述压缩机、所述冷凝器、所述膨胀阀和所述蒸发器依次串联形成一个冷媒系统,所述电加热器位于所述冷凝器和所述蒸发器之间并共同形成一个再生风系统。
本发明中的一种转轮除湿用热泵再生系统通过采用热泵技术,提高生成再生风的效率,从而提高能源利用效率,同时使用电加热,提高控制精度,并解决热泵供热温度不高的问题,另外将再生出风用作蒸发器的热源,进一步提高效率。
在一些实施方式中,所述压缩机用于产生高温高压制冷剂蒸气。由此,描述了压缩机的具体用途,其能够从蒸发器中通入低压制冷剂蒸气,并对其进行压缩,形成高温高压制冷剂蒸气。
在一些实施方式中,所述冷凝器用于产生高压制冷剂液体。由此,描述了冷凝器的具体用途,其能够从压缩机中通入压缩成高温高压制冷剂蒸气,并对其进行冷凝,形成高压制冷剂液体。
在一些实施方式中,所述膨胀阀为电子膨胀阀。由此,设置了膨胀阀的具体种类。
在一些实施方式中,所述膨胀阀用于产生低压气液两相制冷剂。由此,描述了膨胀阀的具体用途,其能够从冷凝器中通入高压制冷剂液体,并对其进行节流,形成低压气液两相制冷剂。
在一些实施方式中,所述蒸发器用于产生低压制冷剂蒸气。由此,描述了蒸发器的具体用途,其能够从膨胀阀中通入低压气液两相制冷剂,并对其蒸发吸热,形成低压制冷剂蒸气。

在一些实施方式中,所述电加热器位于所述冷凝器和所述转轮的再生区域之间。由此,电加热器可以将经过冷凝器被加热的风进行再加热,精确控制其温度后再作用于转轮。
在一些实施方式中,所述转轮的除湿区域周围设置有除湿风系统。由此,设置除湿风系统能够对经过转轮除湿的风进行除湿。
附图说明
图1为本发明一实施方式的转轮除湿用热泵再生系统的结构示意图;
图2为图1所示转轮除湿用热泵再生系统中的冷媒系统的结构示意图;
图3为图1所示转轮除湿用热泵再生系统的风向示意图。
图中:压缩机1、冷凝器2、膨胀阀3、蒸发器4、电加热器5,转轮6。
具体实施方式
下面结合附图对本发明作进一步详细的说明。
图1示意性地显示了根据本发明的一种实施方式的转轮除湿用热泵再生系统的结构,图2显示了图1中的转轮除湿用热泵再生系统中的冷媒系统的结构,图3显示了图1中的转轮除湿用热泵再生系统的风向。如图1-3所示,该系统主要包括压缩机1、冷凝器2、膨胀阀3、蒸发器4和电加热器5等设备,压缩机1、冷凝器2、膨胀阀3和蒸发器4通过管道依次串联,共同构成一个制冷剂管路,能够用于循环利用制冷剂,也称为冷媒系统。其中,冷凝器2和蒸发器4相对设置,而电加热器5则设置在冷凝器2和蒸发器4之间,三者可用于形成再生风,从而可以共同构成一个再生风系统。
该系统主要作用于除湿系统的转轮6上,而转轮6包括再生区域(图示中为其上部)和除湿区域(图示中为其下部)。其中,再生区域伸入到冷凝器2和蒸发器4之间,与冷媒系统中的设备有所交互,电加热器5位于冷凝器2和转轮6的上部的再生区域之间。
压缩机1用于产生高温高压制冷剂蒸气。具体来说,在冷媒系统中,从蒸发器4处通入压缩机1的低压制冷剂蒸气,会经过压缩机1压缩形成高温高压制冷剂蒸气。
冷凝器2用于产生高压制冷剂液体。具体来说,在冷媒系统中,制冷剂在经过压缩机1压缩成为高温高压制冷剂蒸气后,会通入到冷凝器2中,冷凝器2可以对其进行冷凝,形成高压制冷剂液体。其中,冷凝器2在冷凝时会向周围释放热量。
膨胀阀3用于产生低压气液两相制冷剂。具体来说,在冷媒系统中,制冷剂在经过冷凝器2冷凝形成高压制冷剂液体后,会通入到膨胀阀3中,经过膨胀阀3节流并形成低压气液两相制冷剂。
优选的,膨胀阀3为电子膨胀阀,也可以根据使其情况选择其他合适的膨胀阀。
蒸发器4用于产生低压制冷剂蒸气。具体来说,在冷媒系统中,制冷剂在经过膨胀阀3节流并形成低压气液两相制冷剂后,会通入到蒸发器4中,经由蒸发器4对其进行蒸发,形成低压制冷剂蒸气。其中,蒸发器4在蒸发时会向周围吸收热量。
而蒸发器4所形成的低压制冷剂蒸气会通入到压缩机1中,再次经由压缩机1压缩形成高温高压制冷剂蒸气,由此则通过该冷媒系统实现了制冷剂的循环利用。
在使用该系统时,转轮6的再生区域的风向为从冷凝器2流向蒸发器4。具体来说,将冷空气通入并先经过冷凝器2,并吸收冷凝器2在冷凝时所释放的热量而加热达到一定的温度,再经过电加热器5的再加热,可以对其温度进行进一步提升,并且精确控制到适当的程度;然后,温度较高的新风通过转轮6吸湿并降温,此时再生风的温度依然较高,则可以在随后的运行中通过蒸发器4,可以用于给蒸发器4供热。
此外,在转轮6的除湿区域周围设置有除湿风系统,而设置除湿风系统能够对经过转轮除湿的风进行除湿。
由此可见,本发明中的一种转轮除湿用热泵再生系统通过采用热泵技术,提高生成再生风的效率,从而提高能源利用效率,同时使用电加热,提高控制精度,并解决热泵供热温度不高的问题,并可通过电加热精确控制出风温度,将再生出风用作蒸发器的热源,从而进一步提高了生成再生风的效率。
以上所述的仅是本发明的一些实施方式。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。
