1. What is A/C BTU per Sq Ft Calculator?

Definition: This calculator estimates the cooling load in BTU/h based on the area in square feet and the cooling requirement per square foot.

Purpose: It helps determine the appropriate air conditioning capacity needed for a space.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q = A \times \text{BTU/ft}^2 \]

Where:

\( Q \) — Cooling load (BTU/h)
\( A \) — Area (square feet)
\( \text{BTU/ft}^2 \) — Cooling requirement per square foot (BTU/h·ft²)

Explanation: The area is multiplied by the cooling requirement per square foot to get the total cooling load.

3. Importance of Cooling Load Calculation

Details: Proper cooling load estimation ensures efficient AC sizing, energy savings, and optimal comfort.

4. Using the Calculator

Tips: Enter the area in square feet and BTU per square foot (default 20 BTU/h·ft² for typical rooms). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical BTU per square foot value?
A: For standard rooms, 20 BTU/h·ft² is common. Sunrooms may need 30-40 BTU/h·ft².

Q2: How does ceiling height affect the calculation?
A: Higher ceilings may require increasing the BTU per square foot value.

Q3: When would I use a different BTU per square foot value?
A: Adjust for factors like insulation quality, window area, sunlight exposure, and room usage.

Q4: Does this include heat from occupants or appliances?
A: No, additional BTU may be needed for kitchens, server rooms, or crowded spaces.

Q5: How do I convert this to tons of cooling?
A: Divide BTU/h by 12,000 (1 ton = 12,000 BTU/h).
