Psychrometric Formulations:
• Leaving DB: Tdb2 = ADP + BF · (Tdb1 − ADP)
• Total Capacity: Qtotal = ṁa · (h₁ − h₂) [kW]
• Sensible Ratio: SHR = Qsens / Qtotal
• Condensate Rate: ṁw = ṁa · (w₁ − w₂) × 3600 [L/h]
• Leaving DB: Tdb2 = ADP + BF · (Tdb1 − ADP)
• Total Capacity: Qtotal = ṁa · (h₁ − h₂) [kW]
• Sensible Ratio: SHR = Qsens / Qtotal
• Condensate Rate: ṁw = ṁa · (w₁ − w₂) × 3600 [L/h]

Apparatus Dew Point & Bypass Factor
The portion of air that passes untouched through fin spaces is represented by the Bypass Factor $BF$. The condition curve connects state 1 directly toward $ADP$:
Tdb2 = ADP + BF · (Tdb1 − ADP)
Sensible Heat Ratio & Dehumidification
When the coil surface temperature $ADP < T_{dew1}$, simultaneous cooling and moisture condensation occur. Deeper 6–8 row coils achieve $BF \le 0.08$ for deep moisture removal.
Key Engineering Assumptions
- Standard atmospheric pressure $P = 101.325\,\text{kPa}$.
- Ideal gas mixture thermodynamics for dry air and water vapor.
- Chilled water specific heat $c_p = 4.186\,\text{kJ/(kg·K)}$.
