Step 2: Calculate Cooling Wants, Tabla para calcular btu aire acondicionado
Decide the specified temperature distinction between the room and the skin surroundings. A basic rule of thumb is to subtract 20°F from the skin temperature for a cushty indoor temperature. If you wish to cool the room to 72°F (22°C) in an space with a 90°F (32°C) outdoors temperature, the temperature distinction is eighteen°F (10°C).
- Subtract 20°F from outdoors temperature to find out desired indoor temperature.
- Calculate temperature distinction between indoor and outside temperatures.
Step 3: Calculate BTU Necessities
Use the next system to calculate the BTU necessities:
BTU (British Thermal Items) = (Room Sq. Footage x Temperature Distinction) / 400
This system assumes a 72°F (22°C) indoor temperature and a 12°F (6.7°C) temperature distinction for correct consolation.
| Room Sq. Footage (ft2) | Temperature Distinction (°F) | BTU Necessities (BTU) |
|---|---|---|
| 100 ft2 | 15°F | 375 BTU/hour |
| 200 ft2 | 18°F | 720 BTU/hour |
Step 4: Take into account Insulation, Home windows, and Doorways Components
