AC Tonnage Formula:
| From: | To: |
AC tonnage calculation helps determine 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:
Where:
Explanation: This formula calculates the required cooling capacity in tons based on the area to be cooled, considering typical Indian climate conditions.
Details: Correct AC sizing is essential for energy efficiency, proper humidity control, and equipment longevity. An undersized AC will struggle to cool the space, while an oversized unit will short cycle, reducing efficiency and comfort.
Tips: Measure your room's length and width to calculate square footage. For irregularly shaped rooms, divide into rectangular sections and add them together. Consider factors like ceiling height, insulation, and sun exposure 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 a safety margin for optimal cooling.
Q2: What if my room has high ceilings?
A: For rooms with 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 significant sun exposure may require 10% more cooling capacity. North-facing rooms may need slightly less.
Q4: Should I consider the number of occupants?
A: For spaces with more than 2 people regularly, add approximately 600 BTU per additional person.
Q5: What about kitchen areas?
AKitchens generate additional heat, so add 4000 BTU to the calculated requirement if including kitchen space.
