1. What is the Split AC Tonnage Calculator?

The Split AC Tonnage Calculator helps determine the appropriate air conditioning capacity needed for a space based on its area and BTU requirements per square meter. It converts square meters to square feet and calculates the required tonnage for efficient cooling.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ Ton = \frac{(Square Meters \times BTU per sq m \times 10.7639)}{12000} \]

Where:

\( Square Meters \) — Area of the space in square meters
\( BTU per sq m \) — British Thermal Units required per square meter
\( 10.7639 \) — Conversion factor from square meters to square feet
\( 12000 \) — Conversion factor from BTU to refrigeration tons

Explanation: The formula converts the area from square meters to square feet, calculates total BTU requirement, and then converts BTU to refrigeration tons.

3. Importance of AC Tonnage Calculation

Details: Proper AC tonnage calculation is crucial for energy efficiency, optimal cooling performance, and preventing system overload. An undersized unit will struggle to cool the space, while an oversized unit will cycle too frequently, reducing efficiency and comfort.

4. Using the Calculator

Tips: Enter the area in square meters and the BTU requirement per square meter. Typical BTU values range from 300-500 BTU/sq m depending on insulation, sunlight exposure, and climate conditions.

5. Frequently Asked Questions (FAQ)

Q1: Why convert square meters to square feet in the calculation?
A: BTU requirements are traditionally calculated per square foot, so conversion is necessary when starting with metric measurements.

Q2: What is a typical BTU per square meter value?
A: For well-insulated spaces, 300-350 BTU/sq m is typical. For spaces with poor insulation or high sun exposure, 400-500 BTU/sq m may be needed.

Q3: How many square meters can 1 ton AC cool?
A: Approximately 15-20 square meters with standard insulation, depending on climate conditions and BTU requirements.

Q4: Should I round up the calculated tonnage?
A: It's generally recommended to round up to the nearest standard AC size (0.5, 1, 1.5, 2 tons etc.) for optimal performance.

Q5: Are there other factors to consider beyond area?
A: Yes, ceiling height, number of windows, insulation quality, number of occupants, and heat-generating appliances all affect cooling requirements.
