DAIKIN VRF INDOOR UNITS

Unit	DXF Block	Location	Status
U380	*U380	Inside zone, near SE corner ~6.88m E, ~0.50m N from SW	APPROXIMATE
U370 / U371	U370 / U371	~2.7m EAST of zone (adjacent area)	Outside zone
U328	*U328	~10m+ east (different B3 area)	Outside zone

Coordinate mapping is approximate. The furniture DXF (meters) and HVAC DXF (millimeters) use different origins. Positions derived from offset calculation: HVAC_X = Furniture_X x 1000 + 203,000. HVAC contractor must confirm exact unit positions on the updated floor plan.

AIR DEVICES (DIFFUSERS/GRILLES)

#	DXF Coords (mm)	Mapped Position	Inside Zone?
1	X: 252,428 \| Y: 274,072	~1.73m E, ~0.04m N from SW	Near south wall
2	X: 249,780 \| Y: 274,421	~0.9m west of zone	No — outside
3	X: 249,780 \| Y: 273,376	~0.9m west of zone	No — outside
4	X: 248,776 \| Y: 274,421	~1.9m west of zone	No — outside
5	X: 248,776 \| Y: 273,376	~1.9m west of zone	No — outside
6	X: 246,104 \| Y: 274,073	~4.6m west of zone	No — outside

CRITICAL FINDING: Only 1 indoor unit (U380) and 1 diffuser appear to be inside/near the yellow zone. The remaining equipment (U370/U371 + 5 diffusers) serve adjacent areas WEST and EAST of the zone. This confirms the "last mile" approach — existing ductwork reaches the area but delivery points need to be redesigned for acoustic rooms.

ACOUSTIC HVAC STRATEGY

Action	Detail
Indoor unit (U380)	Relocate to corridor/editing zone (non-critical area). Must NOT be in VO Live Room or Control Room.
Oversize final drops	Increase duct diameter by 1-2 sizes to reduce velocity. Target: flow velocity < 3 m/s in duct.
Acoustic plenum boxes	Expanded boxes with 50mm rockwool lining (60 kg/m3). Face area: 44x44 cm minimum for 600 CFM at 1.5 m/s.
Inline silencers	Rectangular baffle silencers. Max duct size 250mm to fit in 60cm ceiling space.
Flexible S-curve	Inside VO room: hard pipe transitions to flexible acoustic duct in S-curve. Breaks line-of-sight sound path.
Diffuser sizing	~2.5x standard face area needed. Target: terminal velocity ≤ 1.5 m/s at diffuser face.
NC budget	HVAC alone must achieve NC-10 to NC-12 per duct run (margin for NC-15 total in VO room).
