The Mandatory Minimum Energy Performance Standards for Air conditioners, liquid chilling packages and heat pumps with electrically driven compressors for space heating and cooling must meet the ASANS 941 SANS/EN 54511-3 standards while in Energy Consumption cooling mode only.
The standard specifies test methods for the rating and performance of air conditioners, liquid chilling packages and heat pumps using either air, water or brine as heat transfer media, with electrically driven compressors when used for space heating and cooling.
This standard was adopted by law on the 28th of November 2014 through the notice "Compulsory specification for energy efficiency and labelling of electrical and electronic apparatus (VC 9008)" and it enter into force in different phases according to the electrical equipment. Concerning air conditioners and heat pumps, the date of entry into force is Eighteen (18) months after the publication of the notice.
The mandatory MEPS level is 3.2<=EER>3.0, and it was developed in alignment with the EU directive of 2011.
