InRow RC Application Note

This application note describes the control process for the APC InRow RC cooling unit, which cools air from the hot aisle and delivers it to the cold aisle at a set temperature. It details the unit's operation in three environmental models (open aisle, Hot Aisle Containment System, and Rack Air Containment System) and explains how it modulates fan speed and fluid valve position to maintain rack inlet temperatures between 68-77°F.
