1. What is AC Tonnage Calculation?

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

2. How Does the Calculator Work?

The calculator uses the AC tonnage formula:

\[ T = \frac{A \times 25}{12000} \]

Where:

\( T \) — AC tonnage (tons)
\( A \) — Room area (square feet)
25 — BTU per square foot factor
12000 — BTU per ton conversion factor

Explanation: The formula calculates the required cooling capacity in tons based on room area, using a standard 25 BTU per square foot requirement and converting BTUs to tons (1 ton = 12,000 BTU).

3. Importance of Proper AC Sizing

Details: Correct AC sizing is crucial for energy efficiency, comfort, and equipment longevity. An oversized unit cycles frequently, wasting energy, while an undersized unit runs continuously without achieving desired temperature.

4. Using the Calculator

Tips: Enter the room area in square feet. The calculator will determine the recommended AC tonnage. Consider additional factors like ceiling height, insulation, and sun exposure for more precise sizing.

5. Frequently Asked Questions (FAQ)

Q1: What is a "ton" in AC terminology?
A: One ton of cooling equals 12,000 BTU per hour, representing the amount of heat needed to melt one ton of ice in 24 hours.

Q2: Is 25 BTU per square foot sufficient for all rooms?
A: This is a general guideline. Rooms with high ceilings, poor insulation, or significant sun exposure may require 30-35 BTU per square foot.

Q3: What size AC for a 500 sq ft room?
A: Approximately 1.04 tons (500 × 25 ÷ 12000 = 1.04), so a 1-ton unit would be appropriate.

Q4: Can I use this for central AC systems?
A: This calculator provides a basic estimate. For central AC, professional load calculation considering entire home factors is recommended.

Q5: What if my room has unusual features?
A: For rooms with high ceilings, large windows, or special requirements, consult with an HVAC professional for accurate sizing.
