  2. 01/User Benefit 02/Installer Benefit

  3. User Benefit • Line Up • Outstanding Energy Efficiency • Precision Control • GREE Subcooling • Better Efficiency & Noise & Anti-Corrosion • Advanced Soft Control • Reliable Oil Control

  4. Line up – Basic Models 8HP 10HP 16HP 14HP 12HP Max 4 ODU to 64HP

  5. Outstanding Energy Efficiency 21.4%UP GMV5 GMV4 5.7 5.72 5.55 5.5 5.2 5.0 4.62 4.55 4.56 4.56 4.55 4.0 3.0 2.5 2.0 1.5 1.0 0.5 0 8HP 12HP 10HP 14HP 16HP

  6. How to Achieve ? High Efficiency Comp DC Fan Motor & Dual EXV

  7. 180 Sine Wave Modulation & Step less Control ●Digital stepless Control 20HZ~120HZ ●180o sine wave Modulation

  8. Precision Control Dual 960 Pulse ODU EXV 2000 Pulse IDU EXV DC Fan Motor EXV A EXV B

  9. GREE SubcoolingTechnology Conventional Cycle GS Cycle • Two stage compression with mid-range pressure of the refrigerant • GREE Subcooling Technology ensures a stronger, more comprehensive flow rate of the refrigerant. GS Diagram GS Cycle Turbo Inter-Cooler Subcooling PHE Intercooler Inverter Compressor

  10. Better Efficiency & Noise & Anti-Corrosion New Fan Blade New Guiding Structure Golden Fin with Louver Exchange Efficiency Air Flow Noise Anti-Corrosion 3~5dB(A) Down 180% UP 300% UP 22% UP Efficiency&Noise&Anti-Corrosion GMV 5 GMV 5 GMV 4 GMV 4 Tube pipe Inner Groove Turbo-B PHE Intercooler GMV 4 GMV 5 GMV 5 GMV 4

  11. Advanced Soft Control-Energy saving & Quiet Operation Automatic energy-saving Night Silence Mode Save 15% The system can memorize ambient Temp and shift to Night Mode auto regarding low loading at night. Compulsory energy-saving Compulsory Silence Mode Save 20% 3 modes can be choosen and minimum for complete inverter AC can be lower than 45dB(A).

  12. Reliable Oil Control Total efficiency 99.9% Outdoor heat exchanger Class 1 oil separator Pressure control Class 2 oil separator No Accumulator Design Oil Return Simulation Two Stage Oil Separate compressor EXV 98% 95% Indoor heat exchanger Accumulator Pressure control GMV4 Cancel GMV5

  13. Wider operation range Outdoor operation range: -20℃~52 ℃ Power supply voltage range:

  14. Installer Benefit • Flexible Piping Installation • Flexible ODU Installation • Space Saving • Compact and Lighter • Sequential Compressor Operation • Emergency Operation • Easier Access for Status Check and Option Settings

  15. Flexible Piping Installation ●Max total piping length—1000m（3280ft） ●Max actual piping length—165m （540ft） ●Max height difference between ODU and IDU—90m（300ft） ●Maxpiping length from firstbranch to the farthest IDU—40m（130ft）

  16. Flexible ODU Installation Four grades ESP available: 0Pa、30Pa、50Pa、80Pa Max 80Pa

  17. Space Saving 50m 90m Space Saving 40m

  18. Compact and Lighter vs GMV 4 (12HP) GMV 5 (12 HP) GMV 5 Space 25% Net Weight Foot print 0.95 m2 0.71 m2 25% 20% 350 kg 280 kg • GMV5(12HP) saves 25% more space than GMV 4(12HP) • GMV5(12HP) 20% lighter than GMV 4(12HP)

  19. Sequential Compressor Operation Variable Variable Variable Fixed Fixed Fixed Fixed Fixed Fixed • Compressor priority is changed sequentially Compressor Operation Priority 1st Cycle 1 4 7 2 5 8 3 6 9 2nd Cycle 3 6 9 1 4 7 2 5 8 3rd Cycle 2 5 8 3 6 9 1 4 7

  20. Emergency Operation Fan (Dual Fan system)） Compressor(8HP~16HP) Modular（18HP~64HP）

  21. Easier Access for Status Check and Option Settings • Checking the outdoor unit’s status and setting is now easy. There is no need to remove the entire front cover to access the control panel thanks to a convenient opening on the front of the outdoor unit. GMV 5 Conventional Auto Commissioning 1 Option Settings Auto Error Check 2 3 Running Data Check Auto Gas Charge Vacuumize Mode 4 5 6

  22. Decreased CO2 Emission • GMV 5 is a highly efficient product with advanced eco-friendly technology which has decreased carbon dioxide (CO2) emission.
