The Singapore National Environment Agency (NEA) hosted an industry consultation to announce the plan of including variable refrigerant flow air conditioners (VRF A/C) into the Minimum Energy Performance Standards (MEPS)/Mandatory Energy Labeling (MELS) requirement. 

Details to note:

Products: 3-phase VRF A/C with size up to 270 kW

Proposed MEPS: Integrated Energy Efficiency Ratio (IEER) 4.35

where IEER = (0.020*EER100%)+ (0.617*EER75%)+ (0.238*EER50%)+ (0.125*EER25%and  EER = Total Cooling Capacity (kW)/ Effective Power Input (kW)

Test standard and condition: ISO 15042 based on T1 (standard cooling capacity rating conditions for moderate climates). Two cassette type indoor units to be tested.

Proposed tick rating for VRF A/C:

Tick rating

5

6.15 and above​

4

5.70 to <6.15

3

5.25 to <5.70

2

4.80 to <5.25

1

4.35 to <4.80

Energy label is to be displayed on product and all publicity materials.
