There are a variety of ways that the refrigeration units for computer room can be situated. One setup that has been successful is the process of cooling air and having it dispensed through an elevated floor. The air rises through the perforated sections, forming cold aisles. The cold air flows through the racks where it picks up heat before exiting from the rear of the racks. The warm exit air forms hot aisles behind the racks, and the hot air returns to the refrigeration unit intakes, which are positioned above the floor.

对计算机机房的制冷有各种不同的方法。其中的一个设置已成功的通过冷却空气的过程，它是一种高架地板分配。空气通过上升的孔段，形成冷通道。冷空气流经空调将热由机架的后方带出。带出的暖空气在机架的后面形成热通道，和热空气位于地板上方返回到制冷机组的摄入量。
