Abstract:

A device stores control settings for an air conditioning unit for a space that houses power-consuming equipment. The air conditioning unit includes an economizer configured to supply outside cooling air when the economizer is in an active state. The device receives an inside temperature value associated with the space, and receives a real-time or near-real-time operating load value for the power-consuming equipment. The device determines, based on the inside temperature value, the operating load value, and the control settings, an outside temperature threshold for starting the economizer. The device determines if an outside temperature reading associated with the space is below the outside temperature threshold, and activates the economizer when the outside air temperature reading is below the outside temperature threshold.
