1. What is a BTU per Cubic Foot Cooling Calculator?

Definition: This calculator estimates the cooling load in BTU/h based on the volume of space and the cooling requirement per cubic foot.

Purpose: It helps HVAC professionals and homeowners determine the cooling capacity needed for a given space.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Cooling load (BTU/h)
• \( V \) — Volume of space (cubic feet)
• \( \text{BTU/ft}^3 \) — Cooling requirement per cubic foot (BTU/h·ft³)

Explanation: The volume is multiplied by the cooling requirement per cubic foot to determine the total cooling load needed.

3. Importance of Cooling Load Calculation

Details: Proper cooling load estimation ensures efficient HVAC system sizing, energy efficiency, and comfortable indoor environments.

4. Using the Calculator

Tips: Enter the volume in cubic feet and BTU per cubic foot (default 5 BTU/h·ft³ for general spaces). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical BTU/ft³ value?
A: For general spaces, 5 BTU/h·ft³ is common, but this varies (e.g., 4 for shaded rooms, 6 for sunny rooms, higher for kitchens).

Q2: How do I calculate volume?
A: Multiply length × width × height of the space in feet. For irregular spaces, divide into regular shapes.

Q3: Does this include other heat sources?
A: This is a basic calculation. For precise results, consider occupants, appliances, and insulation factors.

Q4: How does this relate to AC tonnage?
A: 12,000 BTU/h = 1 ton of cooling. Divide your result by 12,000 to estimate required AC tonnage.

Q5: Should I add a safety factor?
A: Yes, consider adding 10-20% to the calculated load for safety margin and future needs.
