1. What is BTU Calculation?

BTU (British Thermal Unit) calculation helps determine the appropriate air conditioner size needed for a space. In Sri Lanka's tropical climate, proper BTU calculation is essential for efficient cooling and energy savings.

2. How Does the Calculator Work?

The calculator uses the standard BTU calculation formula:

Where:

• \( Square Footage \) — Area of the room in square feet
• \( 25 \) — Standard multiplier for Sri Lanka's climate conditions

Explanation: This formula provides a basic estimate of the BTU requirements for a room, which may need adjustment based on specific conditions.

3. Importance of Proper BTU Calculation

Details: Correct BTU calculation ensures your air conditioner is neither undersized (leading to inadequate cooling) nor oversized (resulting in energy waste and poor humidity control).

4. Using the Calculator

Tips: Measure your room's length and width in feet, multiply to get square footage, and enter the value. Consider additional factors like sun exposure, insulation, and room occupancy for more precise results.

5. Frequently Asked Questions (FAQ)

Q1: Why is the multiplier 25 for Sri Lanka?
A: The multiplier 25 accounts for Sri Lanka's tropical climate with high temperatures and humidity levels throughout the year.

Q2: What if my room has high ceilings?
A: For rooms with ceilings higher than 8 feet, consider increasing the BTU calculation by 10-20% to account for the additional volume.

Q3: How does sun exposure affect BTU requirements?
A: Rooms with significant sun exposure may need 10-20% more BTU capacity, while shaded rooms may require 10% less.

Q4: Should I consider the number of occupants?
A: Yes, add approximately 600 BTU for each additional person beyond two in the room.

Q5: What about kitchen areas?
A: Kitchens typically require an additional 4,000 BTU due to heat generated from appliances.
