Energy Savings Potential for Commercial Refrigeration Equipment is a study by Arthur D. Little Inc. that gives a detailed description of energy efficiency measures and the energy-saving potential of refrigeration systems for various applications, including walk-in refrigerators and freezers. This study also has cost and payback period estimates for many energy efficiency measures.

The Industrial Refrigeration Best Practices Guide is a 108-page booklet that discusses best practices for making industrial refrigeration systems both energy-efficient and productive. The guide was developed with the support of the Northwest Energy Efficiency Alliance, and covers refrigeration system basics, best practices for equipment, systems and controls, operation, maintenance, commissioning, tools, and case studies. The web link above provides excerpts from the Guide, and the guide can be purchased from the Industrial Efficiency Alliance.

BC Hydro's Power Smart Tips and Practices web site provides very useful tips on measures that improve the energy efficiency of walk-in refrigerators and freezers:

APS (Arizona Public Service) offers tips on refrigeration energy efficiency measures.

Evaporator Fan Controller for Medium-Temperature Walk-In Refrigerators
This brochure, put out by the U.S. Department of Energy's Office of Industrial Technologies, describes an evaporator fan controller for medium-temperature, walk-in refrigerators. This controller provides energy savings of up to 50 percent.

Energy Savings in Refrigerated Walk-in Boxes
This Technology Installation Review prepared by the U.S. Department of Energy gives an assessment of a new type of control system for evaporator fans in refrigerated walk-in coolers. Energy savings of 10 to 60 percent are reported, depending on the fan motor type and usage pattern.
