1. What is AC Tonnage Calculation?

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.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• \( Square Footage \) — Area of the space in square feet
• \( 25 \) — Standard BTU per square foot for Indian conditions
• \( 12000 \) — Conversion factor (1 ton = 12,000 BTU)

Explanation: This formula calculates the required cooling capacity in tons based on the area to be cooled, considering typical Indian climate conditions and building standards.

3. Importance of Proper AC Sizing

Details: Correct AC sizing is essential for energy efficiency, proper humidity control, and optimal comfort. An undersized AC will struggle to cool the space, while an oversized AC will short cycle, leading to poor humidity removal and higher energy consumption.

4. Using the Calculator

Tips: Measure your room's length and width in feet, multiply them to get square footage, and enter this value. The calculator will determine the appropriate AC tonnage for Indian conditions.

5. Frequently Asked Questions (FAQ)

Q1: Why is 25 BTU per square foot used for India?
A: This value accounts for typical Indian climate conditions, including high temperatures and humidity levels common in most regions.

Q2: What if my room has high ceilings or large windows?
A: For rooms with high ceilings (above 10 feet), large windows, or significant sun exposure, you may need to add 10-20% to the calculated tonnage.

Q3: How does insulation affect AC tonnage requirements?
A: Well-insulated rooms may require slightly less tonnage, while poorly insulated spaces may need additional cooling capacity.

Q4: What are standard AC tonnage sizes available in India?
A: Common split AC sizes in India are 0.75 ton, 1 ton, 1.5 ton, and 2 ton units, with some manufacturers offering intermediate sizes.

Q5: Should I round up or down when choosing AC capacity?
A: It's generally recommended to round up to the nearest available size if your calculation falls between standard capacities, especially for rooms with high heat loads.
