1. What is AC Room Size Calculation?

AC room size calculation helps determine the appropriate air conditioner capacity (in tons) needed for a given room area. Proper sizing ensures optimal cooling efficiency, energy savings, and comfort.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Tonnage \) — AC capacity in tons
• \( Factor \) — Cooling factor (typically 120-180 sq ft/ton in India)
• \( Area \) — Room area in square feet

Explanation: The calculation accounts for typical Indian climate conditions, room insulation, and cooling requirements.

3. Importance of Proper AC Sizing

Details: Correct AC sizing prevents energy waste, ensures efficient cooling, extends equipment life, and maintains comfortable humidity levels.

4. Using the Calculator

Tips: Enter AC tonnage (typically 0.75-2 tons for residential use) and cooling factor (150 sq ft/ton is standard for India). Adjust factor based on room conditions.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard factor for Indian conditions?
A: 150 sq ft per ton is standard, but this can vary from 120-180 sq ft/ton based on room insulation, sunlight exposure, and local climate.

Q2: How many tons AC do I need for a 200 sq ft room?
A: Using the standard factor of 150 sq ft/ton: 200 ÷ 150 ≈ 1.33 tons. A 1.5-ton AC would be appropriate.

Q3: What factors affect the cooling factor?
A: Room insulation, number of windows, sunlight exposure, ceiling height, number of occupants, and heat-generating appliances.

Q4: Is a bigger AC always better?
A: No, oversized ACs cycle on/off frequently, reducing efficiency, increasing humidity, and shortening equipment life.

Q5: How does O General AC performance differ?
A: O General ACs are known for high performance in Indian conditions, with better cooling efficiency and durability.
