1. What is AC Tonnage Calculation?

AC tonnage calculation determines the cooling capacity required for a space. One ton of cooling equals 12,000 BTU/h, which represents the amount of heat needed to melt one ton of ice in 24 hours.

2. How Does the Calculator Work?

The calculator uses the AC tonnage formula:

Where:

• \( Ton \) — Cooling capacity in tons
• \( BTU \) — British Thermal Units per hour (BTU/h)

Explanation: This formula converts BTU/h cooling capacity to equivalent tons, which is the standard unit for air conditioning system sizing.

3. Importance of AC Tonnage Calculation

Details: Proper AC tonnage calculation is crucial for selecting the right-sized air conditioning unit. Oversized units short cycle, reducing efficiency and humidity control, while undersized units struggle to cool the space effectively.

4. Using the Calculator

Tips: Enter the BTU/h rating of your air conditioning system. The value must be greater than zero. The calculator will convert it to equivalent tons of cooling capacity.

5. Frequently Asked Questions (FAQ)

Q1: What does "ton" mean in air conditioning?
A: In air conditioning, a "ton" refers to the cooling capacity equivalent to 12,000 BTU per hour, which is the amount of heat needed to melt one ton of ice in 24 hours.

Q2: How many square feet does one ton of cooling cover?
A: Generally, one ton of cooling covers approximately 400-600 square feet, but this varies based on climate, insulation, ceiling height, and other factors.

Q3: What's the difference between BTU and tons?
A: BTU (British Thermal Unit) measures energy, while tons measure cooling capacity. One ton equals 12,000 BTU per hour.

Q4: Can I use this calculation for heat pumps?
A: Yes, the same calculation applies to heat pumps as they use the same cooling capacity measurements.

Q5: Why is proper AC sizing important?
A: Proper sizing ensures energy efficiency, adequate cooling, proper humidity control, and longer system lifespan.
