Abstract: A datacenter room can be associated with multiple computer room air handling units (CRAHUS) capable of transitioning between cooling modes. A management component of the datacenter can separate transitions of different CRAHUS by time intervals. Durations of the time intervals may be determined based on ambient air temperature.

Abstract: A data center includes a computer room with one or more regions, where each region includes air handling components which can be independently controlled, relative to components in other regions. A purge control system in each region can bypass a control system which adjusts the components based on environmental sensor data to command the components to purge the region. Upon the components in a region entering a purge mode, a purge notification signal can be sent to a master control system, which can instruct other control systems in other non-purging regions to limit controller output ranges to last-known values prior to the purge, so that the components in other regions are operated at last-known states while one or more regions are purging. When regions have ceased purging, the regional control systems can re-establish the control loop output ranges. Such re-establishment can include incrementally expanding the output range over time.
