How to use it
- Calculate volume: 25m² × 2.6m = 65m³
- Factor orientación sur + insulation bueno: 50 BTU/m³
- Calculate BTU: 65m³ × 50 = 3250 BTU/h
- To m² method fast: 25m² × 600 BTU/m² = 15000 BTU/h
- Convert a toneladas: 15000 ÷ 12000 = 1.25 toneladas
Common mistakes
- ⚠️ Dimensionar solo per m² without Consider height and orientación
- ⚠️ Not prever capacity additional to techos with mucho sol
- ⚠️ Instalar equipo sobredimensionado (cicla mucho, not deshumidifica bien)
Worked example
Calculate BTU for 30m2 room.
Habitación of {area_m2}m² with {height_m}m of height requires equipo of {btu} BTU/h ({toneladas} toneladas). power electrical: {power_kw} kW.
