MELS for Three-Phase VRF Air-Conditioners

Integrated Energy Efficiency Ratio (IEER)

• Any base module/unit of three-phase VRF air-conditioners

  • 1 tick: 4.35 ≤ IEER < 4.80

  • 2 tick: 4.80 ≤ IEER < 5.25 

  • 3 tick: 5.25 ≤ IEER < 5.70

  • 4 tick: 5.70 ≤ IEER < 6.15

  • 5 tick: IEER ≥ 6.15  

Integrated Energy Efficiency Ratio (IEER) = 0.125*COP at 25% + 0.238*COP at 50% + 0.617*COP at 75% + 0.020*COP at 100%. where:

• Coefficient of Performance (COP) is ratio of cooling capacity to effective power consumption at T1 test conditions under ISO 15042(2017).
• Effective Power input is the average power input to the equipment obtained from operation of compressor(s), electric heating devices used only for defrosting, all control and safety devices and operations of all fans, whether provided with equipment or not.
