精密空调是指能够充分满足机房环境条件要求的机房专用精密空调机，是在近30年中逐渐发展起来的一个新机种。计算机机房中摆放计算机设备及程控交换机产品等，由大量密集电子元件组成。要提高这些设备使用的稳定及可靠性，需将环境的温度湿度严格控制在特定范围。早期的机房使用舒适性空调机时，常常出现由于环境温湿度参数控制不当而造成机房设备运行不稳定，数据传输受干扰，出现静电等问题。机房精密空调则是针对现代电子设备机房设计的专用空调，它的工作精度和可靠性都要比普通空调高得多。

如图1所示，本发明实施例提供的一种轻载除湿制冷装置的内部实现原理图；
精密空调机广泛适用于计算机机房、程控交换机机房、卫星移动通讯站、数据集装箱等高精密环境，这样的环境对空气的温度、湿度、气流分布等各项指标有很高的要求，必须由每年365天、每天24小时安全可靠运行的专用机房精密空调设备来保障。
本发明的一种恒温除湿装置由压缩机、位于室外的压缩机下游的冷凝器、及位于室内的压缩机上游的蒸发器、及电子膨胀阀、及蒸发器中间的节流机构连接构成。本发明广泛适用于计算机机房、程控交换机机房、卫星移动通讯站、数据集装箱等高精密环境，当然，也适用于家用领域。本实施例所提供的所述一种轻载除湿制冷装置，包括压缩机(1)、冷凝器(2)及蒸发器(3)、及电子膨胀阀(8)，所述压缩机(1)输入端与所述蒸发器(3)输出端相连，所述压缩机(1)输出端与所述冷凝器(2)输入端相连，所述冷凝器(2)输出端与所述蒸发器(3)输入端相连，所述电子膨胀阀A(8)串联于所述冷凝器(2)及所述蒸发器(3)之间，所述各端之间均使用制冷剂管道(4)相连，其特征在于：
所述压缩机(1)，用于将进入所述压缩机(1)的气态制冷剂进行压缩,以使所述气态制冷剂的压强和温度升高，且将升高了温度和压强后的气态制冷剂输出给冷凝器(2)；
所述冷凝器(2)，用于将所述升高了温度和压强后的气态制冷剂进行降温，以使所述气态制冷剂凝结为液态制冷剂后输出给蒸发器(3)；
所述蒸发器(3)，分为蒸发器1部(5)和蒸发器2部(7)，所述蒸发器1部(5)与所述蒸发器2部(7)之间串联有节流装置(6)；
在制冷并除湿的情况下，所述电子膨胀阀A(8)关闭一部分，对从所述冷凝器(2)输入的所述液态制冷剂进行节流，以降低所述液态制冷剂的压强 和温度并形成气液两相的制冷剂后，输出给所述蒸发器(3)；
所述蒸发器1部(5)和蒸发器2部(7)将所述电子膨胀阀A(8)输出的所述气液两相的制冷剂与环境进行热量交换，所述节流装置(6)不进行节流，使所述气液两相的制冷剂的温度升高以变为气态制冷剂，用于降低环境温度以对所述环境进行除湿后，输出给压缩机(1)；
在恒温除湿的情况下，所述电子膨胀阀A(8)全开以不进行节流，所述蒸发器1部(5)，用于将所述液态制冷剂与环境进行热量交换，以降低所述液态制冷剂的温度并使环境温度升高后，并将降低温度后的液态制冷剂输出给节流装置(6)；具体地，此时输出的所述降低温度后的液态这冷机任然是高压的液体；

有益效果：当需要恒温除湿时，对于制冷剂，从冷凝器里流进蒸发器1之后高于环境温度，进行放热，降低了温度，此时制冷剂仍为高压液态；然后液态制冷剂流过蒸发器中间的节流机构后，变成了低压低温的制冷剂液体，流进蒸发器2，温度低于环境温度，进行吸热，温度升高，变为气体后流回压缩机进行循环。因此，对于制冷剂，在通过蒸发器1和蒸发器2时，温度先降低后升高；
而对于室内空气，空气先经过蒸发器2温度降低，再经过蒸发器1温度升高，室内空气经过空调整体温度基本上保持不变。此时，蒸发器2可以持续进行除湿，不断降低室内湿度，就实现了恒温除湿的功能。
当需要制冷时，所述电子膨胀阀A不完全打开，以进行节流。
