Title: MULTI-ZONE VAPOR COMPRESSION SYSTEM AND METHOD FOR CONTROLLING MULTI-ZONE VAPOR COMPRESSION SYSTEM
Abstract:
A multi-zone vapor compression system (MZ-VCS) includes a compressor connected to a set of heat exchangers controlling environments in a set of zones, a supervisory controller determining a set of control inputs for controlling a vapor compression cycle of the MZ-VCS, and a set of capacity controllers. The supervisory controller is a model predictive controller (MPC) determining the set of control inputs using a model of the MZ-VCS including a linear relationship between thermal capacities of each heat exchanger and temperatures in a corresponding zone controlled by the heat exchanger. Each capacity controller enforces the linear relationship between the thermal capacity and the temperature in the corresponding zone.
