1. What is AC Tonnage Calculation?

AC tonnage calculation determines the cooling capacity needed for a space by converting British Thermal Units per hour (BTU/h) to tons of air conditioning capacity. One ton of cooling equals 12,000 BTU/h.

2. How Does the Calculator Work?

The calculator uses the AC tonnage formula:

Where:

• \( Tons \) — Air conditioning capacity in tons
• \( BTU/h \) — British Thermal Units per hour
• \( 12000 \) — Conversion factor (1 ton = 12,000 BTU/h)

Explanation: This formula converts cooling capacity from BTU/h to the standard ton measurement used in HVAC industry.

3. Importance of AC Tonnage Calculation

Details: Proper AC tonnage calculation is crucial for selecting the right-sized air conditioning unit for optimal efficiency, comfort, and energy savings. Oversized or undersized units can lead to poor performance and higher costs.

4. Using the Calculator

Tips: Enter the BTU/h value from your air conditioner specifications or cooling load calculation. The value must be greater than zero for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What is a ton in air conditioning?
A: One ton of cooling equals the amount of heat needed to melt one ton of ice in 24 hours, which is equivalent to 12,000 BTU/h.

Q2: How do I determine the BTU/h needed for my space?
A: BTU/h requirements depend on room size, insulation, windows, climate, and number of occupants. Professional load calculations are recommended.

Q3: What are common residential AC tonnage sizes?
A: Common sizes range from 1.5 tons (18,000 BTU/h) for small apartments to 5 tons (60,000 BTU/h) for larger homes.

Q4: Why is proper tonnage important?
A: Proper sizing ensures efficient operation, adequate dehumidification, and prevents short cycling (oversized) or inadequate cooling (undersized).

Q5: Can I use this for commercial AC systems?
A: Yes, the formula applies to both residential and commercial systems, though commercial systems often use larger tonnage units.
