AC Tonnage Formula:
| From: | To: |
AC tonnage calculation determines the appropriate air conditioner size needed for a space based on its square footage. Proper sizing is crucial for energy efficiency and optimal cooling performance in Indian climate conditions.
The calculator uses the standard formula for Indian conditions:
Where:
Explanation: This formula calculates the required AC capacity in tons based on the area to be cooled, considering typical Indian weather conditions and building standards.
Details: Correct AC sizing ensures energy efficiency, proper humidity control, longer equipment life, and better temperature regulation. An undersized AC will struggle to cool, while an oversized unit will short-cycle, reducing efficiency.
Tips: Measure your room's length and width to calculate square footage. For irregular shapes, divide into rectangles and sum the areas. Consider factors like ceiling height, sun exposure, and insulation which may affect the calculation.
Q1: Why is 25 BTU per square foot used for India?
A: This value accounts for typical Indian climate conditions with high temperatures and humidity levels, providing adequate cooling capacity.
Q2: What if my room has high ceilings?
A: For ceilings higher than 8 feet, increase the square footage by 10-15% to account for the additional volume.
Q3: How does sun exposure affect AC tonnage?
A: Rooms with direct sunlight may require 10% more capacity, while shaded rooms might need 10% less.
Q4: Should I consider the number of occupants?
A: For rooms with more than 2 people regularly, add approximately 600 BTU per additional person.
Q5: What about kitchen areas?
A: Kitchens generate additional heat, so add 4000 BTU to the calculated requirement for kitchen spaces.
