PCM Thermal Energy Storage Formulation:
• Total Stored Energy: Etot = Mpcm [ cps(Tm−Ti) + Lf + cpl(Tin−Tm) ] / 3600 [kWh]
• Charging Effectiveness: ε = 1 − e−NTU, where NTU = UA / (ṁ · cp,htf)
• Average Charging Power: Q̇avg = ṁ · cp,htf · (Tin − Tm) · ε [kW]
• Total Charging Time: tcharge = Etot / Q̇avg [hours]
• Total Stored Energy: Etot = Mpcm [ cps(Tm−Ti) + Lf + cpl(Tin−Tm) ] / 3600 [kWh]
• Charging Effectiveness: ε = 1 − e−NTU, where NTU = UA / (ṁ · cp,htf)
• Average Charging Power: Q̇avg = ṁ · cp,htf · (Tin − Tm) · ε [kW]
• Total Charging Time: tcharge = Etot / Q̇avg [hours]

📘 Calculation Methodology & Latent Storage Standards
High Energy Density at Constant Temperature
Latent storage absorbs or releases large amounts of thermal energy ($L_f \approx 150 - 350\,\text{kJ/kg}$) at nearly isothermal conditions, offering $3 - 5\times$ higher volumetric energy density than water tanks.
NTU-Effectiveness Charging Model
Computes the transient temperature evolution of the heat transfer fluid as it circulates through embedded finned tubes inside the solidifying or melting PCM core.
Key Engineering Assumptions
- Enthalpy-based phase change model with well-defined melting point $T_m$.
- Uniform PCM encapsulation without thermal degradation.
- Applicable to solar domestic hot water, HVAC peak load shifting, and industrial heat recovery.
