1. What is HVAC Load Calculation?

HVAC load calculation determines the heating and cooling capacity needed for a space. In Florida's climate, cooling load is particularly important for proper air conditioning system sizing.

2. How Does the Calculator Work?

The calculator uses the Florida state standard formula:

Where:

• \( BTU/h \) — British Thermal Units per hour (cooling capacity)
• \( Area \) — Square footage of the space
• 25 — Standard multiplier for Florida climate

Explanation: This simplified calculation provides a quick estimate based on Florida's warm climate and typical building characteristics.

3. Importance of Proper HVAC Sizing

Details: Correct HVAC sizing ensures energy efficiency, proper humidity control, and system longevity. Oversized units short-cycle while undersized units can't maintain comfort.

4. Using the Calculator

Tips: Enter the total square footage of the conditioned space. For more accurate results, consider a Manual J calculation for your specific building.

5. Frequently Asked Questions (FAQ)

Q1: Why is the multiplier 25 for Florida?
A: This accounts for Florida's hot, humid climate which requires more cooling capacity per square foot than cooler regions.

Q2: Is this calculation sufficient for all buildings?
A: While useful for quick estimates, complex buildings may require Manual J calculations considering insulation, windows, and other factors.

Q3: How does this differ from calculations for northern states?
A: Northern states often use lower multipliers (20-22) since cooling demands are less extreme.

Q4: Should I round up the calculated BTU/h?
A: HVAC systems come in standard sizes. Choose the next available size if your calculation falls between standard capacities.

Q5: Does this account for humidity control?
A: The Florida multiplier indirectly accounts for humidity, but proper system selection is also important for humidity removal.
