将描述采用热通道或冷通道封闭的数据中心的独特功能和设计要求，重点介绍它们对系统设计的影响。其中包括确定进入机组的适当温度和湿度水平、加湿和除湿、计算机组气流以及独特的控制方案。在传统建筑中，进入冷却设备的空气的温度和湿度通常假定与空间中的空气的温度和湿度相等。对于安全壳，必须单独考虑离开冷却设备的空气、进入服务器的空气和返回冷却设备的空气的温度和湿度。 由于进入冷却设备的空气温度很高，冷却盘管通常又热又干，因此无法对空间进行除湿。在这些情况下，除主冷却装置外，还必须使用其他设备进行除湿。仍然可以使用冷却装置进行加湿，但必须注意湿度测量。确定单位气流也是一项挑战。由于大多数气流通过服务器，因此单位气流必须与累积服务器气流紧密匹配。机组控制器必须确定服务器气流，或使用代理，并相应地改变机组气流。还必须特别考虑冷却源的控制和DX设备的使用。 引文:伊利诺伊州芝加哥ASHRAE会议论文

The unique features and design requirements of Data Centers utilizing hot or cold aisle containment will be described with a focus on their impact on system design. These include determining the proper temperature and humidity levels entering the unit, humidification and dehumidification, calculating unit airflow, and unique control schemes. With traditional architectures, the temperature and humidity of the air entering the cooling equipment is typically assumed to be equal to that of the air in the space. With containment the temperature and humidity of the air leaving the cooling equipment, the air entering the servers, and the air returning to the cooling equipment must be considered separately. Due to the high temperature of the air entering the cooling equipment the cooling coil is often hot and dry prohibiting the unit from dehumidifying the space. In these cases dehumidification must be done by equipment other than the primary cooling units. Humidification can still be done with the cooling units but care must be taken in the humidity measurement. Determining the unit airflow is also a challenge. Since most of the airflow passes through the servers, unit airflow must be closely matched to the cumulative server airflow. The unit controller must determine the server airflow, or use a proxy, and vary the unit airflow accordingly. Special consideration must also be given to control of the cooling source and in the use of DX equipment.
