1. What is AC Tonnage Calculation?

AC tonnage calculation determines the cooling capacity needed for a space. One ton of refrigeration 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 standard conversion formula:

Where:

• \( Ton \) — Tons of refrigeration
• \( BTU \) — British Thermal Units per hour (BTU/h)

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

3. Importance of Proper AC Sizing

Details: Proper AC sizing 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, reducing efficiency and increasing humidity.

4. Using the Calculator

Tips: Enter the BTU rating of your AC unit or the calculated BTU requirement for your space. The calculator will convert it to tons of refrigeration.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between BTU and tons?
A: One ton of refrigeration equals 12,000 BTU per hour. This standard measurement originated from the amount of heat needed to melt one ton of ice in 24 hours.

Q2: How do I determine the BTU requirement for my space?
A: BTU requirements depend on room size, insulation, windows, climate, and other factors. Professional load calculations are recommended for accurate sizing.

Q3: Are LG AC units different in tonnage calculation?
A: No, LG AC units use the same standard calculation (1 ton = 12,000 BTU/h) as other manufacturers. The calculation is industry-standard.

Q4: What's the typical tonnage for residential AC units?
A: Residential units typically range from 1.5 to 5 tons, with 2-3 tons being common for average-sized homes.

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