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
