Mexico Proposes New Energy Efficiency Standards for Certain Split Air Conditioners

Mexico's Ministry of Energy is seeking input from interested parties by 26 September on a proposal to establish minimum energy efficiency standards for ductless mini-split air conditioners with variable refrigerant flow and free discharge, with a nominal cooling capacity of 1 Wt to 19,050 Wt. Excluded from this proposal are water heat pumps, units designed to be used with additional ducts, portable units (other than window units) having an exhaust duct condenser, multi-split units with a frequency condenser and/or variable refrigerant flow, and products covered by other mandatory Mexican energy efficiency standards.

The new standard (NOM-026-ENER-2015) would establish a minimum seasonal energy efficiency ratio ranging from 4.10 Wt/We (14 BTU/h/W) for air conditioners with a cooling capacity from 10,600 to 19,050 BTU/hr to 4.68 Wt/We (16 BTU/h/W) for air conditioners with a cooling capacity up to 5,859 BTU/h. The proposal also would also set definitions, sampling, acceptance, test methods, labelling and conformity evaluation requirements for these products. The standard would enter into force 180 days from the date of publication of a final regulation in Mexico's official journal.
