More Time to Comment on Proposed Changes to Testing of Air Conditioners, Heat Pumps
The Department of Energy has extended through Jan. 20, 2012, the period for comments, data and information regarding a supplemental notice of proposed rulemaking concerning the test procedure for residential central air conditioners and heat pumps. The amendments proposed in this SNPRM would change the off-mode laboratory test steps and calculation algorithm to determine off-mode power consumption for these products to shorten the duration and burden of this testing. Specifically, DOE proposes that the applicable test and calculation combination will depend on whether the tested unit is equipped with a crankcase heater and whether or not the crankcase heater operation is controlled by the unit during the test.
DOE has proposed to make these changes effective 180 days after publication of a final rule and to require that the compliance date for these amendments correspond to the Jan. 1, 2015, compliance date for the amended energy conservation standards for residential central air conditioners and heat pumps.
