Summary

This article provides an overview of a predictive refrigeration control technology being developed by the CSIRO, including preliminary results from a real-world case study to be presented in a subsequent part. The technology is designed to intelligently alter the operation of a refrigeration system by dynamically determining optimal operating temperature set-points and run-time schedules to reduce energy consumption and operating costs, whilst maintaining local constraints such as capacity control, defrost cycles, product quality and safety. Utilising “self-learning” model predictive control (MPC) techniques from control theory and computer science domains, the technology makes use of forecasting to move away from a reactionary control philosophy. By taking into account anticipated external conditions, electricity tariffs and adaptively learning the thermal response of the system, more optimal control and pre-cooling strategies can be employed tailored to operating objectives, including minimising operating cost and reducing energy consumption, while ensuring internal temperature conditions are satisfied.
