1. What is an AC BTU per Cubic Foot Calculator?

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

Purpose: It helps HVAC professionals and homeowners determine the appropriate air conditioning capacity needed for a space.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Cooling load (BTU per hour)
• \( V \) — Room volume (cubic feet)
• \( \text{BTU/ft}^3 \) — Cooling factor (BTU per hour per cubic foot)

Explanation: The room volume is multiplied by the cooling factor to determine the total cooling capacity needed.

3. Importance of Cooling Load Calculation

Details: Proper cooling load estimation ensures efficient AC operation, proper temperature control, and energy savings.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's a typical BTU per cubic foot value?
A: For residential spaces, 5 BTU/h per cubic foot is common, but this can vary based on insulation, climate, and room usage.

Q2: How do I calculate room volume?
A: Multiply length × width × height of the room in feet.

Q3: When would I use a higher BTU/ft³ value?
A: Use higher values (6-10) for rooms with high heat loads (kitchens, server rooms) or poor insulation.

Q4: Does this include other heat sources?
A: This is a basic calculation. For precise results, consider adding heat from occupants, appliances, and sunlight.

Q5: How does this relate to AC tonnage?
A: 12,000 BTU/h equals 1 ton of cooling. Divide your result by 12,000 to get required AC tonnage.
