HVAC CONTROLLER WITH PREDICTIVE COST OPTIMIZATION

摘要

A building (10) HVAC system (100) includes a waterside system (120; 200) and an airside system (130; 300). The waterside system (120; 200) consumes one or more resources from utility providers to generate a heated and/or chilled fluid. The airside system (130; 300) uses the heated and/or chilled fluid to heat and/or cool a supply airflow provided to the building (10). A HVAC controller (402) performs an integrated airside/waterside optimization process to simultaneously determine control outputs for both the waterside system (120; 200) and the airside system (130; 300). The optimization process includes optimizing a predictive cost model that predicts the cost of the resources consumed by the HVAC system (100), subject to a set of optimization constraints including temperature constraints for the building (10). The HVAC controller (402) uses the determined control outputs to control the HVAC equipment of the waterside system (120; 200) and the airside system (130; 300).
