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 — BTU conversion factor (1 ton = 12000 BTU)

Explanation: The formula calculates the required cooling capacity by converting room area to BTU requirements and then to tons of cooling capacity.

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: 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: Are there other factors besides area that affect AC sizing?
A: Yes, factors like ceiling height, insulation, window size, sunlight exposure, and room usage also impact cooling requirements.

Q3: What happens if I install an oversized AC unit?
A: Oversized units cool too quickly without proper dehumidification, leading to poor comfort and increased energy costs from frequent cycling.

Q4: Can I use this calculator for commercial spaces?
A: This calculator is designed for residential rooms. Commercial spaces have different requirements and should be assessed by HVAC professionals.

Q5: What's the typical tonnage for different room sizes?
A: Generally, 1-1.5 tons for 100-150 sq ft, 1.5-2 tons for 150-250 sq ft, and 2-2.5 tons for 250-350 sq ft rooms.
