Description

一种加湿***及空调器
本申请要求于2018年11月5日提交中国专利局、申请号为201811308541.5、发明名称为“一种加湿***及空调器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及空调技术领域，更具体地说是涉及一种加湿***及空调器。
背景技术
目前恒温恒湿空调器向室内进行加湿的方式具有多种,其中喷雾加湿是最常用的一种加湿方式。传统的喷雾加湿***都是在空调室内的送风风道内喷冷水水雾，然后冷空气和冷水水雾一同通过风机送到室内，但会存在一下两个缺点：一是冷水水雾蒸发慢，导致加湿效率低，效果差；二是由于向送风风道内喷冷水水雾，冷风从送风风道吹出的过程中会吹出水珠。
发明内容
本发明要解决的技术问题是提供一种加湿***及空调器，以提高加湿效率。
本发明的技术方案为：提供一种加湿***，包括制冷回路、加湿水路以及送风风道，所述制冷回路包括压缩机、蒸发器和第一冷凝器，所述加湿水路包括依次连接的供水部、增压泵和喷雾器，还包括第二冷凝器，所述第二冷凝器连接在供水部与增压泵之间，且所述第二冷凝器还连接在压缩机与第一冷凝器之间或第一冷凝器的冷媒出端，通过增压泵使供水部的水在所述第二冷凝器中与冷媒进行换热后经喷雾器喷入送风风道中。
所述第二冷凝器采用水\冷媒换热器。
所述送风风道中设有风机，所述送风风道由分隔开的风道主体和加湿风道构成，所述喷雾器将水喷入所述加湿风道中，所述加湿风道中的空气和风道主体中的空气均通过所述风机送出。
所述蒸发器设于所述风道主体中。
所述第一冷凝器设于所述风道主体中。
所述加湿风道设置在所述风道主体的***。
所述蒸发器与第一冷凝器之间连接有节流阀。
所述第二冷凝器与所述蒸发器之间连接有节流阀。
所述压缩机与蒸发器之间连接有气液分离器。
本发明还提供一种空调器，包括上述所述的加湿***。
所述空调器为恒温恒湿空调器。
本发明的有益效果为：
1、由于从压缩机出来的高温冷媒会先通过第二冷凝器，冷媒在通过第二冷凝器时，水会与高温冷媒进行换热，或者由于从第一冷凝器出来的中温冷媒会通过第二冷凝器，冷媒在通过第二冷凝器时，水会与高温冷媒进行换热，使得水的温度升高，升温后的水再通过喷雾器喷入送风风道中形成水雾，水雾在送风风道中与空气混合,由于升温后的水的温度比空气温度高很多,这样水雾中的水珠会很快的蒸发到空气中提高空气湿度，从而提高加湿效率以及效果。
2、升温后的水通过喷雾器喷入加湿风道中形成水雾，水雾中的水珠会很快的蒸发到空气中提高空气湿度，由于水雾中的水珠会很快的蒸发到空气中提高空气湿度，这样加湿风道中加湿后的空气与风道主体中的空气混合后通过风机吹出时，不会吹出水珠。
附图说明
图1为本发明实施例中空调器的结构示意图。
具体实施方式
如图1所示，本发明实施例中提出的加湿***，应用于空调器中，加湿室内空气。加湿***包括制冷回路、加湿水路以及送风风道，制冷回路为常规的空调制冷回路，制冷回路包括压缩机1、蒸发器3和第一冷凝器2。加湿水路包括依次连接的供水部6、增压泵8和喷雾器9。
为了提高空调器的加湿效率，该加湿***还包括第二冷凝器7，第二冷凝器7连接在供水部6与增压泵8之间，且第二冷凝器7还连接在压缩机1与冷凝器2之间，通过增压泵8使供水部6的水在第二冷凝器7中与冷媒进行换热后经喷雾器9喷入送风风道5中。由于从压缩机出来的高温冷媒会先通过第二冷凝器，冷媒在通过第二冷凝器时，由于冷媒的温度比水的温度高很多，水会与高温冷媒进行换热，使得水的温度升高(常温水变成高温水)，升温后的水再通过喷雾器喷入送风风道中形成水雾，水雾在送风风道中与空气混合,由于升温后的水的温度比空气温度高很多,这样水雾中的水珠会很快的蒸发到空气中提高空气湿度，从而提高加湿效率以及效果。而且本***是直接利用从压缩机出来的冷媒的热量来加热水，充分利用能量，无需额外能量，实现热量回收。冷媒通过第二冷凝器后，进入第一冷凝器，进行常规的制冷循环。
本实施例中，第二冷凝器7采用水\冷媒换热器。
蒸发器3与第一冷凝器2之间连接有节流阀11，压缩机1与蒸发器3之间连接有气液分离器10。
为了避免风从送风风道吹出的过程中会吹出水珠，送风风道5由分隔开的风道主体52和加湿风道51构成，喷雾器9将水喷入加湿风道51中，送风风道5中设有风机4，加湿风道51中的空气和风道主体52的空气均通过风机4送出。升温后的水通过喷雾器喷入加湿风道中形成水雾，水雾中的水珠会很快的蒸发到空气中提高空气湿度，由于水雾中的水珠会很快的蒸发到空气中提高空气湿度，这样加湿风道中加湿后的空气与风道主体中的空气混合后通过风机吹出时，不会吹出水珠。
本实施例中，风机4设置在送风风道的送风末端，风机4采用离心风机，风机4数量为两个，加湿风道51设置在风道主体52的***。
本实施例中，蒸发器3设于风道主体52中，这样室内制冷时，避免冷风吹出水珠。当然，也可以将第一冷凝器设于风道主体中，这样室内制热时，避免热风吹出水珠。
本实施例中，蒸发器3、风机4、送风风道5、增压泵8和喷雾器9都属于空调器的室内机12，压缩机1、第一冷凝器2、第二冷凝器7、气液分离器10和节流阀11都属于空调器的室外机13。
在另一实施例中，第二冷凝器连接在供水部与增压泵之间，且第二冷凝器还连接在第一冷凝器的冷媒出端(即冷媒从第一冷凝器中出来的一端)。由于从第一冷凝器出来的中温冷媒会通过第二冷凝器，冷媒在通过第二冷凝器时，由于冷媒的温度比水的温度高很多(中温冷媒的温度比高温冷媒的温度低，但还是比常温水高很多)，水会与中温冷媒进行换热，使得水的温度升高(常温水变成中温水)，升温后的水再通过喷雾器喷入送风风道中形成水雾，水雾在送风风道内中与空气混合,由于升温后的水的温度比空气温度高很多,这样水雾中水珠会很快的蒸发到空气中提高空气湿度，从而提高加湿效率以及效果。
本实施例中，节流阀连接在第二冷凝器与蒸发器之间。
本发明还提供一种空调器，包括上述的加湿***，空调器为恒温恒湿空调器。
以上的具体实施例仅用以举例说明本发明的构思，本领域的普通技术人员在本发明的构思下可以做出多种变形和变化，这些变形和变化均包括在本发明的保护范围之内。
