冷凝器22可以设置在送风房1的外侧或者顶部,如附图3所示,所述送风房1的顶部设置有与冷凝器22对应的集气罩24,所述冷凝器22设置在集气罩24上,减少整体长度的增加,所述集气罩24上设置有散热风机23,散热风机23利用控制模块进行控制,开启后向集气罩24送入气流,增加集气罩24内部气压,然后气流通过冷凝器22逸出,带走冷凝器22上的热量。
实施例3:
如图9~10所示,在实施例1的基础进行的改造,所述热通道27平行设置 在冷通道26两侧,此时,热通道27的数量为两个,冷通道26的数量为一个,加湿器的数量也为两个而将送风房的内部空间分为两组混气室29和送气室30,两个混气室29与热通道27一一对应,两个送气室30合二为一,共同为一个冷通道服务,降低组件的数量和成本,可以安装两排服务器,扩大服务器容量。
实施例4:
如图11~12所示,在实施例3的基础上,增加了辅助降温设备,如图8所示的工作原理图,控制模块通过对阀门的控制,实现外界新风与热风的混合,经过加湿器后送入冷通道,实现对负载安装机架所在区域的温湿度控制。
实施例5:
如图6~7所示,所述机房17和送风房1的数量也可以为两个,两个机房17端部的送风房相对设置,相对设置的两个送风房之间设置有间隙或者封闭式维护通道25,所述封闭式维护通道25、冷通道26和热通道27的端部分别设置有安全门板15,方便工作人员进行维护。
综上所述,本发明指出的一种数据中心新风温湿度控制***,特别设计了送风房1,运输与组装灵活,可以配合多种结构的数据中心,实现数据中心的改造、新建及组合,充分利用自然新风进行数据中心的温湿度控制,降低能耗。
以上所述仅为本发明的实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书内容所作的等效结构或等效流程变换,或直接或间接运用在其它相关的技术领域,均同理包括在本发明的专利保护范围内。
