Heat removal systems and methods with automated fire suppression for data centers

In an open-loop heat removal system for a building such as a data center or a home, cool air is supplied to the building by a chilling unit and hot air is expelled from the building without recycling, recirculating, or re-cooling the hot air. For fire suppression, the system receives temperature reading(s) from temperature sensor(s) and determines whether any temperature reading reaches or exceeds a temperature that indicates presence of a fire. If so, a louver positioned over an inlet module is automatically or programmatically closed, shutting off air supply to the building. The system determines whether the building is under a negative pressure internally. If not, an exhaust fan at the outlet of the building is turned on to create a negative pressure internally. The system determines whether an oxygen level of the building indicates that the fire has been contained. If not, a sprinkler system is activated.
