Patent ID: 8406929

Claim:
An air conditioning control system for a facility, the air conditioning control system comprising: a plurality of local field controllers distributed about the facility, at least one of the plurality of local field controllers gathering air conditioning data of a cooling system from an associated local region of the facility; and a main processor connected with each of the plurality of local field controllers, the main processor receiving the air conditioning data from the at least one of the plurality of local field controllers, executing an optimization routine with the air conditioning data, and controlling the cooling system according to the optimization routine, the controlling comprising generating one or more control signals to manage an operation of the cooling system, at least one of the one or more control signals representing one or more operational setpoints of the cooling system, the one or more operational setpoints being determined based on the optimization routine, and being are selected from the group of operational setpoints that consists of: a chilled water system differential pressure setpoint, a chilled water supply temperature setpoint, a condenser water temperature setpoint, a condenser water flowrate setpoint, a condenser water temperature differential setpoint, a supply air static pressure setpoint, and a supply air temperature setpoint.
