控制器还可以对图1所示的蒸发制冷模块105、机械制冷模块106、风墙风机阵列107进行开启或者关闭控制，以实现工况下的不同的制冷模式。
下面通过应用实施例1至4对本实用新型实施例的不同的制冷模式分别介绍。
应用实施例1
如图2所示，为本实施例的新风制冷模式工作原理图。该实施例的整个 制冷过程中，机械制冷模块106、蒸发制冷模块105均不需要开启，为完全的自然冷却。
当室外环境温度为某个设定值(推荐为10℃～25℃)的时候，本实施例可以开启新风制冷模式，此时新风送风模块的新风进风风阀101开启，热风回风模块的热风回风风阀109开启，风墙制冷模块工作，热风排风模块的热风排风风阀111和热风排风风机112开启，循环回风风阀113关闭。整个工作流程如下：自然空气301从新风送风模块中经过多级过滤以后形成洁净空气流入到送风腔114中，由于送风腔114中的机械制冷模块106、蒸发制冷模块105关闭，洁净空气通过风墙风机阵列107的风机抽送到服务器设备间的冷通道201供服务器设备203使用；冷空气被服务器设备吸入并加热以后排入到热通道202的回风天花板中，热风回风风阀109打开，热通道202的热空气抽送到回风腔110中，热风排风风阀111此时打开，通过热风排风风机112将热空气排放到室外空气中。
应用实施例2
如图3所示，为本实施例的新风+蒸发冷却制冷模式工作原理图。该实施例的整个制冷过程中，蒸发制冷模块105打开进行绝热加湿降温，机械制冷模块106不需要开启，为完全的自然蒸发冷却，增加了服务器设备全年自然冷却的运行时间，达到了节能冷却的目标。
当室外环境温度为某个设定值(推荐为25℃～35℃)同时空气湿度比较低的时候，本实施例可以开启新风+蒸发冷却制冷模式，此时新风送风模块的新风进风风阀101开启，热风回风模块的热风回风风阀109开启，蒸发制冷模块105和风墙制冷模块工作，热风排风模块的热风排风风阀111开启，循环回风风阀113关闭。整个工作流程如下：自然空气301从新风送风模块中经过多级过滤以后形成洁净空气流入到送风腔114中，送风腔114中的蒸发制冷模块105打开，通过对洁净空气进行加湿绝热降温降低气流的温度，由于机械制冷模块106关闭，绝热加湿降温后的洁净空气通过风墙风机阵列107的风机抽送到服务器设备间的冷通道201供服务器设备203使用；冷空气被服务器设备吸入并加热以后排入到热通道202的回风天花板中，热风回风风阀109打开，热通道202的热空气抽送到回风腔110中，热风排风风阀111 此时打开，通过热风排风风机112将热空气排放到室外空气中。
应用实施例3
如图4所示，为本实施例的新风+热通道回风混合制冷模式工作原理图。该实施例的整个制冷过程中，机械制冷的冷源主机不需要开启，机械制冷模块106不工作，蒸发制冷模块105不工作，为完全的自然冷却。
当室外环境温度为某个设定值(推荐为0℃～10℃)的时候，本实施例可以开启新风+热通道回风混合制冷模式，此时新风送风模块的新风进风风阀101部分开启，风墙制冷模块工作，热风回风模块的热风回风风阀109开启，热风排风模块的热风排风风阀111和热风排风风机112部分开启，循环回风模块的循环回风风阀113部分开启。整个工作流程如下：自然空气301从新风送风模块中经过多级过滤以后形成洁净空气，洁净空气通过风墙风机阵列107的风机抽送到服务器设备间的冷通道201供服务器设备203使用；冷空气被服务器设备吸入并加热以后排入到热通道202的回风天花板中，热风回风风阀109打开，热通道202的热空气抽送到回风腔110中，此时热风排风模块的热风排风风阀111和热风排风风机112部分开启，将回风腔中部分热空气抽送到外界环境中；同时，回风腔中的部分热空气通过部分开启的循环回风风阀113送入到送风腔114；送入送风腔的热空气与引入的自然空气301通过风墙的风机作用进行合理的比例均匀混合，最后形成合适温度的冷气流重新送入到冷通道201供服务器设备203使用。
应用实施例4
如图5所示，为本实施例的机械制冷模式工作原理图。该实施例的整个制冷过程中，蒸发制冷模块105不工作，机械制冷的冷源主机需要开启，机械制冷模块106根据负荷工作，蒸发制冷模块105不工作，热风排风模块的热风排风风阀111和热风排风风机112关闭，为完全的机械制冷。
当室外环境温度高于某个设定值(推荐为35℃)的时候，此时新风温度过高，蒸发冷却无法将气流温度降低到可用温度；或者低于设定值(推荐为0℃)的时候，此时新风温度过低，会导致服务器设备不能正常工作；或者当室外环境的相对湿度大于设定值的时候，为了避免带入过多的水汽进入到服务器设备间，此时不能引入新风。此时本实施例可以开启完全机械制冷模式， 此时新风送风模块的新风进风风阀101关闭，热风回风模块的热风回风风阀109开启，机械制冷模块106工作，机械制冷的冷源主机开启，热风排风模块的热风排风风阀111和热风排风风机112关闭，循环回风模块的循环回风风阀113开启，在本实施例和服务器设备间内部形成空气内循环。整个工作流程如下：新风进风风阀101关闭，送风腔内的空气401通过风墙风机阵列107的风机抽送到服务器设备间的冷通道201供服务器设备203使用；冷空气被服务器设备吸入并加热以后排入到热通道202的回风天花板中，控制器控制热风回风风阀109自身的风阀开度将热通道的热空气抽送到回风腔110中，此时循环回风风阀113开启，将热空气送入到送风腔中，通过机械制冷模块106中的冷媒介质对热空气进行降温处理，最后送出冷气流重新进行下一次的制冷气流循环。
尽管上述对本实用新型实施例做了详细说明，但本实用新型实施例不限于此，本技术领域的技术人员可以根据本实用新型实施例的原理进行修改。
工业实用性
本实用新型实施例通过模块化的拼装方式可实现机房和数据中心制冷系统的灵活组合和快速搭建及安装，且运输方便，高效节能。另外，且本实用新型实施例的内部结构高度集成，使得内部气流形成固定流道，从而降低了对建筑结构的苛刻要求，降低了现场施工工程量，减少了土建复杂程度。
