HVAC SYSTEM USING MODEL PREDICTIVE CONTROL WITH DISTRIBUTED LOW-LEVEL AIRSIDE OPTIMIZATION AND AIRSIDE POWER CONSUMPTION MODEL

摘要

A building HVAC system includes an airside system having a plurality of airside subsystems, a waterside system, a high-level model predictive controller (MPC), and a plurality of low-level airside MPCs. Each airside subsystem includes airside HVAC equipment configured to provide heating or cooling to the airside subsystem. The waterside system includes waterside HVAC equipment configured to produce thermal energy used by the airside system to provide the heating or cooling. The high-level MPC is configured to perform a high-level optimization to generate an optimal airside subsystem load profile for each of the plurality of airside subsystems. The optimal airside subsystem load profiles optimize a total cost of energy consumed by the airside system and the waterside system Each of the low-level airside MPCs is configured to operate the airside HVAC equipment of an airside subsystem according to the load profile for the airside subsystem.
