1. What is the Aircon Size Calculation?

The aircon size calculation determines the cooling capacity (in tons) needed for a room based on its area. Proper sizing ensures efficient cooling and energy use.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Area \) — Room area in square feet
• 20 — BTU per square foot (standard cooling requirement)
• 12000 — Conversion factor (1 ton = 12,000 BTU/hour)

Explanation: The formula calculates the required cooling capacity in tons based on room area and standard cooling requirements.

3. Importance of Proper Aircon Sizing

Details: Correct aircon sizing is crucial for energy efficiency, proper cooling, and system longevity. Oversized units cycle too frequently, while undersized units run continuously without adequate cooling.

4. Using the Calculator

Tips: Measure your room's length and width to calculate area (length × width). Enter the area in square feet for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What if my room has high ceilings?
A: For ceilings over 8 feet, multiply the result by 1.25 to account for additional volume.

Q2: What about rooms with lots of windows?
A: For sun-facing rooms or those with large windows, consider increasing capacity by 10-20%.

Q3: What are standard aircon sizes?
A: Common residential sizes are 1, 1.5, 2, 2.5, 3, 3.5, 4, and 5 tons.

Q4: Does insulation affect sizing?
A: Yes, well-insulated rooms may need less capacity, while poorly insulated rooms may need more.

Q5: Should I round up or down?
A: Generally round up to the nearest standard size, but consult with an HVAC professional for your specific needs.
