Cómo funciona Calculadora BTU de Aire
Sizing an air conditioner correctly is vital for climate control. A unit that is too small cannot keep up, while one that is too large will cycle off too quickly, leaving the room damp.
This calculator uses standard US Department of Energy rules: 20 BTU of cooling power per square foot of room area, adjusted for thermal variables like occupant heat load, direct solar heating, and ovens.
Base BTU/hr = Room Area (sq ft) × 20Adjusted BTU = Base BTU ± Solar Offset (+10% Sunny / -10% Shaded) + Occupant Load (+600 BTU per person > 2) + Kitchen Offset (+4,000 BTU)1 ton of refrigeration = 12,000 BTU/hr.

Preguntas frecuentes: Calculadora BTU de Aire
How do you determine what size AC I need?
Calculate the square footage of the room (Length × Width). Multiply that by 20 to get the base BTU load. Add 600 BTUs per person if more than two people occupy the room, and add 4,000 BTUs if the room is a kitchen.
What happens if an AC is too big for a room?
It cools the room too fast, which sounds good but is highly inefficient. The unit will satisfy the thermostat before it has had time to remove humidity from the air, resulting in a clammy, cold, and humid room.
