5. Current Methods ㈜ 옴니벤트 5/24
Traditional Air Conditioning
Method

6. Current Methods 6/24
1) Single Zone Air Conditioning System
(One Zone Control)
Air Return types:
• Duct Return
• Room Space + Duct Return
• Ceiling Space + Duct Return
No Independent Zone Control
→ Constant Energy Consumption

7. Current Methods ㈜ 옴니벤트 7/24
2) Multi Split System (Multi Zone Control)
Independent Zone Control
↔ High Installation Cost

8. Current Methods ㈜ 옴니벤트 8/24
3) Individual Multi Duct System
(Multi Zone Control)
Variation A
Independent Zone Control
↔ Unrealistic Ceiling Space Management

9. Current Methods 9/24
3) Individual Multi Duct System
(Multi Zone Control)
Variation B
Utilizing Ceiling space as return path
Independent Zone Control, Low Install Cost
↔ Inefficient Air Flow Management

Variation B
Air Flow & Cooling Efficiency
 Air supply ducts block ceiling space
(return path)
 resulting in inefficient energy control
Pressure Difference between Rooms
 Makes door operation difficult
Air Volume Control
 Large Control Variation of the
conventional dampers makes Air
volume control inefficient
Diffuser Balancing
 Not possible when independent
