1. What Is AC Tonnage Calculation?

AC tonnage calculation determines the appropriate air conditioning capacity needed for a room based on its area. Proper sizing ensures efficient cooling, energy savings, and optimal performance.

2. How Does The Calculator Work?

The calculator uses the AC tonnage formula:

\[ T = \frac{A_{m²} \times 25 \times 0.0929}{12000} \]

Where:

Explanation: This formula converts room area from square meters to square feet, applies standard cooling load requirements, and converts the result to AC tonnage.

3. Importance Of Proper AC Sizing

Details: Correct AC sizing is crucial for energy efficiency, comfort, and equipment longevity. Undersized units struggle to cool, while oversized units short-cycle, wasting energy and reducing dehumidification.

4. Using The Calculator

Tips: Enter the room area in square meters. Ensure accurate measurements for best results. Consider additional factors like ceiling height, insulation, and sun exposure for precise sizing.

5. Frequently Asked Questions (FAQ)

Q1: Why is AC tonnage important?
A: Proper tonnage ensures efficient cooling, lower energy bills, and prevents equipment strain from over or under-sizing.

Q2: What is a standard cooling load factor?
A: 25 BTU per square foot is a common estimate, but this may vary based on climate, insulation, and room usage.

Q3: How accurate is this calculation?
A: This provides a basic estimate. Professional HVAC calculations consider additional factors like windows, insulation, and occupancy.

Q4: What if my room has high ceilings?
A: For rooms with ceilings higher than 8 feet, increase the calculated tonnage by 10-20% to account for additional volume.

Q5: Can I use this for multiple rooms?
A: This calculator is designed for single rooms. For whole-house calculations, sum individual room areas or consult an HVAC professional.
