Regulations 7(2), 8(2) and 12

SCHEDULE 3 Energy Efficiency Classification

1.  The energy efficiency class of a regulated appliance shall be determined in accordance with the following tables. The energy efficiency ratio (EER) shall be determined in accordance with the test procedures of the harmonised standard at conditions T1 “moderate”.

Table 1 Air-cooled air conditioners

Table 1.1

Energy Efficiency class	Split and multi-split appliances
A	3.20<EER
B	3.20≥EER>3.00

D	2.80≥EER>2.60
E	2.60≥EER>2.40
F	2.40≥EER>2.20
G	2.20≥EER
