1. What is AC Tonnage Calculation?

AC tonnage calculation determines the appropriate air conditioning capacity needed for a room based on its square footage. 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 — BTU per ton conversion factor

Explanation: The formula calculates the required cooling capacity in tons based on room area, using a standard of 25 BTU per square foot and converting 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. Undersized units struggle to cool, while oversized units short-cycle, reducing efficiency and humidity control.

4. Using the Calculator

Tips: Enter the room area in square feet. Measure the length and width of the room and multiply to get the area. Ensure accurate measurements for proper AC 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, which represents 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. Factors like ceiling height, insulation, window area, climate, and room usage may require adjustments.

Q3: What if my room has high ceilings?
A: For rooms with ceilings higher than 8 feet, multiply the area by (ceiling height ÷ 8) before using the calculator.

Q4: Should I round up or down when selecting AC capacity?
A: It's generally better to round up to the nearest half-ton for adequate cooling capacity, especially in warmer climates.

Q5: What other factors affect AC sizing?
A: Consider insulation quality, number of windows, sun exposure, number of occupants, and heat-generating appliances in the room.
