AIRFLOW CONTROL SYSTEM WITH EXTERNAL AIR CONTROL

摘要

A cooling system includes one or more air channeling sub-systems that provide cooling air to electronic equipment, at least one heat removal sub-system that removes heat from the cooling air in at least one of the air channeling sub-systems, at least one temperature sensor measures a wet bulb temperature of outside air, and at least one controller. At least one of the air channeling sub-systems includes an outside air damper operable allow outside air into the air channeling sub-system. The at least one controller at least partially opens the outside air damper if a wet bulb temperature measured at the at least one temperature sensor drops to or below a predetermined temperature.

1. A cooling system, comprising:
one or more air channeling sub-systems configured to provide cooling air to electronic equipment, at least one of the air channeling sub-systems comprising an outside air damper operable to selectively allow outside air into the air channeling sub-system;at least one heat removal sub-system configured to remove heat from cooling air in at least one of the air channeling sub-systems;
at least one temperature sensor configured to measure a wet bulb temperature of outside air; and at least one controller coupled in electronic data communication with the at least one temperature sensor and the outside air damper, the at least one controller being configured to at least partially open the outside air damper if a wet bulb temperature measured at the at least one temperature sensor drops to or below a predetermined temperature.
