Psychrometric Reference Guide
Common Conditions:
  • Summer Design: 78°F WB (~38 BTU/lb)
  • Comfort Zone: 62-67°F WB
  • Data Center: 59-64°F WB
  • Winter Return: 55-60°F WB
Key Relationships:
  • Total Load: CFM × 4.5 × Δh
  • Sensible: CFM × 1.08 × ΔT
  • Latent: CFM × 0.68 × Δgr
  • SHR: Sensible ÷ Total
Critical Values:
  • 55°F WB: Dehumidification limit
  • 67°F WB: Comfort upper limit
  • 78°F WB: Typical OA design
  • 80°F WB: Extreme conditions
Best Practices:
  • Use sling psychrometer for accuracy
  • Allow sensor stabilization time
  • Account for altitude effects
  • Verify with multiple readings
