1. What is the AC Tonnage Calculator?

The Air Conditioner Room Size Calculator estimates the required AC tonnage based on room area in square meters. Proper sizing ensures optimal cooling efficiency and energy consumption.

2. How Does the Calculator Work?

The calculator uses the AC tonnage formula:

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

Where:

\( T \) — Required AC tonnage (tons)
\( A_{m²} \) — Room area in square meters
25 — Standard cooling load factor (BTU per square foot)
0.0929 — Conversion factor from m² to square feet
12000 — BTU to tons conversion factor

Explanation: The formula converts room area from square meters to square feet, applies standard cooling load calculations, and converts BTU requirements to tons.

3. Importance of Proper AC Sizing

Details: Correct AC sizing is crucial for energy efficiency, proper humidity control, and preventing short cycling. Oversized units cool quickly but don't remove humidity effectively, while undersized units struggle to maintain temperature.

4. Using the Calculator

Tips: Enter the room area in square meters. Measure the length and width of the room and multiply them to get the area. For irregular rooms, divide into rectangles and sum the areas.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect AC tonnage requirements?
A: Room insulation, ceiling height, window size/direction, number of occupants, heat-generating appliances, and climate zone all impact cooling requirements.

Q2: How accurate is this calculation?
A: This provides a basic estimate. For precise sizing, consult HVAC professionals who consider additional factors like insulation quality and local climate.

Q3: What if my room has high ceilings?
A: For ceilings higher than 2.7 meters, increase the calculated tonnage by 10-15% per additional 0.3 meters of height.

Q4: Can I use this for multiple rooms?
A: Calculate each room separately, or calculate total area for open-plan spaces. For whole-house systems, sum all room areas.

Q5: What's the difference between tons and BTU?
A: 1 ton of cooling equals 12,000 BTU per hour. Tons are commonly used for residential AC sizing in many countries.
