February 4th 2015

On February 4, 2015 the U.S. Department of Energy (DOE) issued a supplemental notice of proposed rulemaking to amend the test procedure proposals presented in a notice of proposed rulemaking (NOPR), published on May 21, 2014. The proposed revisions include modifications to the whole-home dehumidifier test setup and conduct, and revisions to the measurement of energy use in fan-only operation first proposed in the May 2014 NOPR. DOE also introduces a methodology to determine whole-home dehumidifier case volume, clarifies the equations used to calculate corrected relative humidity and capacity for portable and whole-home dehumidifiers, and provides additional technical corrections and clarifications. The additional proposals are to be combined with the initial proposals from May 2014.
