Delhi offices demand discreet, powerful cooling for open-plan layouts, conference rooms, and high-occupancy spaces amid extreme heat (45°C+) and pollution. Cassette AC – ceiling-mounted 4-way units—deliver 360° uniform airflow from suspended ceilings, blending seamlessly without wall clutter. These systems excel in offices with their zoning capabilities, energy efficiency, and quiet operation, making them superior to wall splits for commercial use.
Key Benefits of Cassette AC for Delhi Offices
Cassette units mount flush in ceilings, distributing cool air evenly via 4-directional louvers:
- 360° Airflow Coverage: Ideal for 400-800 sq ft open offices; reaches corners without hot spots.
- Aesthetic Integration: Invisible indoors; only grilles visible, preserving premium office aesthetics.
- Zoning Flexibility: Multiple cassettes link to VRF/VRV outdoor units for independent room control.
- Delhi-Specific Advantages: High ambient operation (up to 54°C); PM2.5 filters combat AQI 400+ pollution.
- Energy Savings: Inverter tech + EC fans yield ISEER 4.0+; 25-35% lower bills vs splits.
- Quiet Performance: Indoor noise <30 dB; perfect for calls/meetings.
Compared to ducted systems, cassettes offer easier retrofits in existing offices.
Step-by-Step Cassette AC Installation Guide
Pre-Installation Planning (1-2 Days):
- Load Calculation: 1 TR per 120-150 sq ft for Delhi offices (add 20% for heat gain/windows).
- Ceiling Assessment: Requires 250-400mm void above suspended ceilings; avoid solid slabs.
- Site Survey: Central placement for airflow; 1m+ clearance from beams/walls.
Installation Process (2-4 Days per Unit):
- Ceiling Opening: Cut precise hole (per unit specs, e.g., 860x860mm for 2TR); reinforce with hangers.
- Indoor Unit Mounting: Secure cassette on 4 suspension rods; level perfectly for drainage.
- Refrigerant Piping: Copper lines (1/2″ liquid, 5/8″ gas) to outdoor unit (up to 50m); insulate fully.
- Drainage: PVC pipe with 1:100 slope; trap prevents odors.
- Electrical Wiring: 3-core control + power cables; voltage stabilizer for Delhi fluctuations.
- Outdoor Unit: Wall/rooftop mount with vibration pads; 1m side clearance.
- Commissioning: Vacuum piping, gas charge (R410A/R32), test 360° swing, BMS link.
Tools Needed: Core cutter, leveler, vacuum pump, manifold gauge.
