Formule
## BTU Calculation **Base BTU = Square Footage × 20** Adjustments: - High ceilings: +5% per foot above 8ft - Sun exposure: ±10% - Extra occupants: +600 BTU each beyond 2 - Kitchen: add 4,000 BTU **1 ton of AC = 12,000 BTU**
Exemple Résolu
300 sq ft room, 8ft ceiling, average sun, 2 occupants.
- 01Base BTU = 300 × 20 = 6,000
- 02Ceiling factor = 1.0 (standard height)
- 03Sun factor = 1.0 (average)
- 04Occupant BTU = 0 (2 is baseline)
- 05Total = 6,000 BTU
- 06Tonnage = 6,000 / 12,000 = 0.5 ton
