Mexico - Draft Mexican Official Standard PROY-NOM-011-ENER-2024: Energy efficiency of central, package and split-type air-conditioners. Limits, test methods and labelling

National Commission for the Efficient Use of Energy -National  Advisory  Committee  on  Standardization  for  the  Conservation  and Rational Use of Energy Resources (CCNNPURRE)​ announces d​​raft Mexican Official Standard PROY-NOM-011-ENER-2024: Energy efficiency of central, package and split-type air-conditioners. Limits, test methods and labelling.  

• The notified draft Mexican Official Standard establishes the minimum seasonal energy efficiency ratio (SEER) for central air-conditioners with variable refrigerant flow. It also specifies the testing methods which must be used to verify compliance and defines the public information labelling requirements.

• It applies to ducted central, package and split-type air-conditioners, powered by electricity, with nominal cooling capacities of 5,275W to 19,050W, which operate by mechanical compression and include an air-cooling evaporator coil, an air-cooled condensing coil and a single-speed (fixed capacity) compressor, an G/TBT/N/MEX/539 - 2 -   inverter (variable refrigerant flow or frequency) compressor or a multi-stage (staged capacity) compressor, with or without reverse cycle, which are manufactured, imported or marketed in Mexico.

• The following are excluded from the scope of this draft Mexican Official Standard: o Split-type, free air discharge, non-ducted air-conditioners (known as mini-split and multi-split), which operate with a single-speed (fixed capacity) compressor or a variable frequency (inverter) compressor.

- Precision equipment.

- Equipment covered by other Mexican Official Standards on energy efficiency.
