Summary

On May 5, 2016, the U.S. Department of Energy (DOE) published a notice of proposed rulemaking (NOPR) to establish new test procedures for certain varieties of compressors. That proposed rulemaking serves as the basis for the final rule. This final rule establishes definitions, materials incorporated by reference, sampling plans, representations requirements, enforcement provisions, and test procedures for certain varieties of compressors. Specifically, this final rule establishes full-load package isentropic efficiency as the applicable energy metric for certain fixed-speed compressors and part- load package isentropic efficiency as the applicable energy metric for certain variable-speed compressors. Finally, this final rule incorporates by reference certain sections of the ISO Standard 1217:2009(E), (ISO 1217:2009(E)), "Displacement compressors-- Acceptance tests," as amended through Amendment 1:2016, as the basis for a test method for determining compressor efficiency. ISO 1217:2009(E) includes a test method for measuring compressor inlet and discharge pressures, actual volume flow rate, electrical input power, package isentropic efficiency, and other compressor performance metrics. This final rule also adopts certain modifications and additions to ISO 1217:2009(E) to increase the specificity of certain testing methods established in ISO 1217:2009(E) and improve the repeatability of tested and measured values.
