Summary

In this document, the U.S. Department of Energy ("DOE" or the "Department") is proposing amended energy conservation standards for variable refrigerant flow (VRF) multi-split air conditioners and VRF multi-split system heat pumps (collectively referred to as "VRF multi-split systems") that rely on a new cooling efficiency metric and are equivalent to those levels specified in the industry standard. DOE has preliminarily determined that it lacks the clear and convincing evidence required by the statute to adopt standards more stringent than the levels specified in the industry standard. This document also announces a public meeting webinar to receive comment on these proposed standards and associated analyses and results.

The agency’s own summary, as published.
