1. What is BTU Calculation?

BTU (British Thermal Unit) calculation helps determine the cooling capacity needed for a space based on its size and other factors. This calculator provides a basic estimate using square footage.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Square Feet \) — Area to be cooled in square feet
• \( BTU per Square Foot \) — Cooling requirement per square foot (typically 20 BTU/ft² for moderate climates)

Explanation: The equation provides a basic estimate of cooling needs. Actual requirements may vary based on insulation, climate, and other factors.

3. Importance of Proper Cooling Calculation

Details: Proper cooling capacity ensures energy efficiency, comfort, and prevents overworking your cooling system.

4. Using the Calculator

Tips: Enter the square footage of the area to be cooled and the BTU requirement per square foot (default is 20 for moderate climates).

5. Frequently Asked Questions (FAQ)

Q1: What's the typical BTU per square foot?
A: In moderate climates, 20 BTU/ft² is common. Hot climates may need 25-30, while cooler areas may need 15-18.

Q2: What other factors affect cooling needs?
A: Ceiling height, insulation, windows, sunlight exposure, and heat-generating appliances all impact cooling requirements.

Q3: Is this calculator suitable for whole-house cooling?
A: This provides a basic estimate. Professional HVAC calculations should consider all factors for whole-house systems.

Q4: How accurate is this calculation?
A: It's a rule-of-thumb estimate. For precise needs, consult an HVAC professional who can perform a Manual J calculation.

Q5: Can I use this for room air conditioners?
A: Yes, this works well for estimating cooling needs for individual rooms or spaces.
