1. What is AC Tonnage Calculation?

AC tonnage calculation determines the cooling capacity needed for a space based on its area and specific cooling factor. It helps in selecting the appropriate air conditioning unit size for optimal efficiency and comfort.

2. How Does the Calculator Work?

The calculator uses the AC tonnage formula:

Where:

• \( Area \) — Area in square meters (m²)
• \( Factor \) — Cooling factor in BTU per square meter (BTU/m²)
• 12000 — Conversion factor from BTU to tons (1 ton = 12000 BTU/hour)

Explanation: The formula calculates the required cooling capacity in tons by multiplying the area by the cooling factor and dividing by the conversion factor.

3. Importance of AC Tonnage Calculation

Details: Proper AC tonnage calculation ensures energy efficiency, optimal cooling performance, and prevents overloading or under-sizing of air conditioning systems.

4. Using the Calculator

Tips: Enter area in square meters and cooling factor in BTU/m². The default factor is 269 BTU/m², which is a common standard value.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard cooling factor value?
A: The standard cooling factor is approximately 269 BTU/m², but this may vary based on climate, insulation, and other factors.

Q2: Why is 12000 used in the formula?
A: 12000 BTU/hour equals 1 ton of cooling capacity, which is the standard measurement for air conditioning systems.

Q3: How does area affect AC tonnage?
A: Larger areas require higher cooling capacity. The calculation directly multiplies area by the cooling factor to determine the total BTU requirement.

Q4: When should I adjust the cooling factor?
A: Adjust the factor for spaces with high ceilings, poor insulation, large windows, or extreme climate conditions.

Q5: Can this calculator be used for commercial spaces?
A: Yes, but commercial spaces often require more detailed calculations considering occupancy, equipment heat load, and ventilation requirements.
