Claim 0:
1. An air handling unit, comprising:
a housing that defines an air flow path therethrough;
a heat exchanger disposed within the air flow path and configured to flow a working fluid therethrough;
a fan system disposed within the housing and configured to increase a speed of an air flow directed along the air flow path;
a nozzle configured to deliver a fire suppression agent into the air flow path; and
a controller comprising a processor and a memory, wherein the memory comprises instructions that, when executed by the processor, are configured to cause the processor to:
operate the fan system to increase the speed of the air flow to a first speed based on a detection of a first amount of the fire suppression agent directed into the air flow path via the nozzle; and
operate the fan system to increase the speed of the air flow to a second speed based on a detection of a second amount of the fire suppression agent directed into the air flow path via the nozzle, wherein the second amount is greater than the first amount, and the second speed is greater than the first speed.
