1. What is AC Ton Calculation?

AC Ton Calculation is a method to determine the appropriate air conditioning capacity needed for a room based on its size and BTU requirements. It helps in selecting the right AC unit for efficient cooling.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Square Feet \) — Area of the room in square feet
• \( BTU per sq ft \) — British Thermal Units per square foot required for cooling
• \( 12000 \) — Conversion factor (1 ton of cooling = 12000 BTU/hour)

Explanation: The formula calculates the required AC tonnage by multiplying the room area by the BTU per square foot and dividing by 12000 to convert to refrigeration tons.

3. Importance of AC Ton Calculation

Details: Proper AC ton calculation ensures energy efficiency, optimal cooling performance, and prevents overloading or underutilization of the air conditioning system.

4. Using the Calculator

Tips: Enter the room area in square feet and the required BTU per square foot. Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is 12000 used in the formula?
A: 12000 BTU/hour equals 1 ton of refrigeration, which is the standard measurement for cooling capacity.

Q2: What is a typical BTU per sq ft value?
A: Typical values range from 20-30 BTU/sq ft for normal conditions, but may vary based on insulation, sunlight exposure, and climate.

Q3: What happens if I choose the wrong AC tonnage?
A: Undersized AC will struggle to cool, while oversized AC will short cycle, reducing efficiency and humidity control.

Q4: Does room height affect the calculation?
A: Yes, rooms with higher ceilings may require additional cooling capacity not accounted for in simple square footage calculations.

Q5: Should other factors be considered?
A: Yes, factors like number of windows, insulation quality, number of occupants, and heat-generating appliances should also be considered for accurate sizing.
