Refrigerator Policy and Test Procedures: Rationale and Benefits for a Move Towards IEC
In 2019, the Northwest Energy Efficiency Alliance (NEEA) began testing residential refrigerator-freezers to better understand the potential energy efficiency benefits of inverter-driven, multi-speed compressors and quantify if the existing U.S. Department of Energy (U.S. DOE) testing methodology adequately captures those potential benefits. Currently, the U.S. DOE test methodology does not entirely align with the test…
