1. What is AC Tonnage Calculation?

AC tonnage calculation determines the appropriate air conditioning capacity needed for a room based on its area. Proper sizing ensures efficient cooling, energy savings, and optimal performance.

2. How Does the Calculator Work?

The calculator uses the AC tonnage formula:

Where:

• \( T \) — AC tonnage (tons)
• \( A \) — Room area (square feet)
• 25 — BTU per square foot factor
• 12000 — Conversion factor (BTU to tons)

Explanation: The formula calculates the required cooling capacity by multiplying room area by 25 BTU per square foot, then converts the result from BTU to tons (1 ton = 12,000 BTU).

3. Importance of Proper AC Sizing

Details: Correct AC sizing is crucial for energy efficiency, comfort, and system longevity. Oversized units cycle frequently, while undersized units struggle to maintain temperature.

4. Using the Calculator

Tips: Enter room area in square feet. The calculator will determine the appropriate AC tonnage needed for efficient cooling.

5. Frequently Asked Questions (FAQ)

Q1: Why is 25 BTU per square foot used?
A: This is a standard factor for average residential rooms with normal ceiling height and insulation.

Q2: What if my room has special conditions?
A: For rooms with high ceilings, poor insulation, or large windows, you may need to adjust the BTU factor accordingly.

Q3: What are common AC tonnage sizes?
A: Common residential sizes are 1 ton, 1.5 ton, 2 ton, 2.5 ton, 3 ton, 3.5 ton, 4 ton, and 5 ton units.

Q4: How accurate is this calculation?
A: This provides a good estimate for standard conditions. For precise sizing, consider factors like insulation, windows, climate, and room usage.

Q5: Can I use this for commercial spaces?
A: This formula is primarily for residential use. Commercial spaces require more complex calculations considering occupancy, equipment, and ventilation.
