HVAC CONTROLLER WITH PREDICTIVE COST OPTIMIZATION

摘要

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

1. A heating, ventilating, or air conditioning (HVAC) system for a building, the HVAC system comprising:
a waterside system comprising a set of waterside HVAC equipment that consumes one or more resources from utility providers to generate a heated and/or chilled fluid; an airside system comprising a set of airside HVAC equipment that receives the heated and/or chilled fluid from the waterside system and uses the heated and/or chilled fluid to heat and/or cool a supply airflow provided to the building; and a HVAC controller that receives inputs from both the waterside system and the airside system and performs an integrated airside/waterside optimization process to determine control outputs for both the waterside HVAC equipment and the airside HVAC equipment simultaneously, wherein performing the integrated airside/waterside optimization process comprises optimizing a predictive cost model that predicts a cost of the one or more resources consumed by the waterside system subject to a set of optimization constraints comprising temperature constraints for the building; wherein the HVAC controller provides the control outputs determined according to the integrated airside/waterside optimization process to the waterside system and the airside system for use in controlling the waterside HVAC equipment and the airside HVAC equipment.
