1. What is AC Capacity Calculation?

AC capacity calculation helps determine the appropriate air conditioner size for a given space. Proper sizing is crucial for energy efficiency, comfort, and equipment longevity in Indian climate conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Area \) — Room area in square feet
• \( Factor \) — BTU per square foot (typically 20-30 for Indian conditions)

Explanation: The factor accounts for various conditions including insulation, sunlight exposure, number of occupants, and heat-generating appliances.

3. Importance of Proper AC Sizing

Details: Correct AC sizing ensures optimal cooling, energy efficiency, proper humidity control, and prevents short cycling. Oversized units cool quickly but don't remove humidity effectively, while undersized units struggle to maintain temperature.

4. Using the Calculator

Tips: Measure your room area accurately. For Indian conditions, use a factor between 20-30 BTU/sq ft depending on room conditions (higher for sun-facing rooms, kitchens, or rooms with many occupants).

5. Frequently Asked Questions (FAQ)

Q1: What factors affect the BTU requirement?
A: Room orientation, insulation, number of windows, ceiling height, number of occupants, and heat-generating appliances all affect the cooling requirement.

Q2: How do I convert BTU to tons?
A: 1 ton of cooling equals 12,000 BTU/h. Divide your BTU result by 12,000 to get the tonnage.

Q3: What's the typical factor for Indian homes?
A: For well-insulated rooms with standard ceiling height, 20-25 BTU/sq ft is typical. For sun-facing rooms or poorly insulated spaces, use 25-30 BTU/sq ft.

Q4: Should I consider room height?
A: Yes, for rooms with higher than standard ceilings (above 9 feet), you may need to increase the capacity calculation.

Q5: What about inverter ACs?
A: While inverter ACs can adjust their capacity, proper sizing is still important for optimal performance and efficiency.
