Claim 8:
9. A control system for a heating, ventilation, and/or air conditioning (HVAC) system, comprising:
a non-transitory, computer-readable medium comprising instructions that, when executed by a processor, are configured to cause the processor to:
operate a fan system of the HVAC system to direct an air flow along an air flow path within a housing of the HVAC system at a first speed based on operation of a fire suppression system of the HVAC system to deliver a fire suppression agent into the air flow path, wherein the housing comprises a heat exchanger disposed within the air flow path and configured to place a working fluid directed through the heat exchanger in thermal communication with the air flow directed along the air flow path via the fan system; and
operate the fan system to direct the air flow along the air flow path within the housing at a second speed based on suspended delivery of the fire suppression agent into the air flow path via the fire suppression system, wherein the second speed is less than the first speed.
