DYNAMIC HVAC AIRSIDE ECONOMIZER HIGH LIMIT START CONTROL
First Claim
1. A method, comprising:
- receiving, by a control device, control settings for an air conditioning unit for a space that houses information and communication technology equipment (ICTE), the air conditioning unit including an economizer configured to supply outside cooling air when in an active state;
receiving, by the control device, an inside temperature value associated with the space;
receiving, by the control device, an electrical current reading associated with one or more of the ICTE and a power supply for the ICTE;
converting, by the control device and based on the control settings, the electrical current reading to a sensible cooling load value; and
determining, by the control device, an outside temperature threshold for starting the economizer, wherein the outside temperature threshold is based on the inside temperature value and the sensible cooling load value.

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.
