This documentis a step-by-step guide to improving energy efficiency in medium to large-scale industrial refrigeration systems for industry. It provides best practice information on system operation and outlines opportunities for improving system performance and efficiency, which will lead to benefits for your business. By following this guide, you will be able to determine what changes can be made in order to improve the performance of equipment, reduce operating costs and improve environmental outcomes. Using refrigeration loads to minimise peak demand energy costs is not covered in this document. The guide has been developed to lead decision makers and service providers through system changes; it is not intended to be a thorough technical guide. References for more detailed technical information are provided.
