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.

2. How Does the Calculator Work?

The calculator uses the standard AC tonnage formula:

Where:

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

Explanation: The formula calculates the cooling capacity needed based on room area, using 25 BTU per square foot as a standard requirement and converting the result 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. An undersized AC will struggle to cool the space, while an oversized unit will cycle frequently, wasting energy and not properly dehumidifying.

4. Using the Calculator

Tips: Enter the room area in square feet. Make sure to measure the length and width accurately and multiply them to get the total area. The calculator will determine the appropriate AC tonnage for your space.

5. Frequently Asked Questions (FAQ)

Q1: What is a "ton" in AC terminology?
A: In air conditioning, one ton 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 room size?
A: Yes, factors like ceiling height, insulation, window size, sunlight exposure, and number of occupants also affect AC sizing requirements.

Q3: What's the typical tonnage for different room sizes?
A: Generally, 1 ton cools 400-600 sq ft, 1.5 tons cools 600-900 sq ft, and 2 tons cools 900-1200 sq ft, but this varies based on other factors.

Q4: What happens if I install the wrong size AC?
A: An undersized AC will run continuously and not cool properly, while an oversized AC will short-cycle, leading to poor humidity control and higher energy costs.

Q5: Should I consult a professional?
A: While this calculator provides a good estimate, it's always recommended to consult with an HVAC professional for precise sizing, especially for complex spaces or commercial applications.
