How to Use the HVAC Calculator
This professional tool helps solve essential HVAC calculations:
- Select Calculation Type: Choose between BTU requirements, duct sizing, or load calculations
- Enter Room Details: Input dimensions, windows, and insulation quality
- Calculate: Get accurate HVAC system specifications
HVAC Formulas Used
- BTU Calculation: (Length × Width × Height × 4) + (Windows × 1000) + Insulation Factor
- Duct Sizing: CFM × 144 ÷ (Velocity × 60) (for rectangular ducts)
- Cooling Load: Based on ASHRAE fundamentals
- Air Flow: CFM = Room Volume × ACH ÷ 60
Why Calculate HVAC Parameters?
- ✅ Proper Sizing: Avoid undersized or oversized systems
- ✅ Energy Efficiency: Optimize performance and reduce costs
- ✅ Comfort Control: Maintain ideal temperature and humidity
- ✅ Code Compliance: Meet building regulations
