1. What is AC Tonnage Calculation?

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

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

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

Explanation: This conversion allows you to determine the appropriate air conditioning unit size based on the cooling capacity required for your space.

3. Importance of AC Tonnage Calculation

Details: Proper AC tonnage calculation is crucial for energy efficiency, comfort, and system longevity. An undersized unit will struggle to cool the space, while an oversized unit will short-cycle, leading to humidity problems and higher energy costs.

4. Using the Calculator

Tips: Enter the BTU value (cooling capacity) of your air conditioning unit. The value must be greater than zero. The calculator will convert BTU/h to tons of cooling capacity.

5. Frequently Asked Questions (FAQ)

Q1: What does "ton" mean in AC terminology?
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 do I determine the right tonnage for my room?
A: Generally, you need about 20 BTU per square foot of living space. For accurate sizing, consider factors like ceiling height, insulation, window size, and climate.

Q3: What's the difference between BTU and tonnage?
A: BTU measures cooling capacity per hour, while tonnage is a standardized unit where 1 ton = 12,000 BTU/h. Tonnage is often used to describe larger AC unit capacities.

Q4: Can I use this for both residential and commercial AC units?
A: Yes, the conversion formula applies to all air conditioning systems, from small residential units to large commercial systems.

Q5: Why is proper AC sizing important?
A: Proper sizing ensures optimal energy efficiency, better humidity control, longer equipment life, and improved comfort. Incorrect sizing can lead to higher energy bills and premature system failure.
