DOE Concludes Negotiations on VRF Equipment
December 27, 2019

The U.S. Department of Energy (DOE) has announced the conclusion of negotiations with manufacturers, utilities, and energy efficiency advocates following the acceptance of an agreement by all parties on the energy conservation standard term sheet regarding variable refrigerant flow multi-split air conditioners and heat pumps (VRF). The term sheet recommends transition from the EER to IEER metric, ASHRAE 90.1-2016 efficiency levels as the federal minimum, and an implementation date of January 1, 2024. The test procedure term sheet agreed upon in October 2019 approves AHRI 1230-2019 as modified during negotiations and as the test procedure. The controls verification procedure, added as Appendix C of AHRI 1230-2019, is intended to confirm steady state testing is performed within “as-shipped” configuration. The test procedure now also accounts for sensible cooling.
