Thermal Energy Storage - Nouman090/ThermoSim GitHub Wiki

The TES component models a thermal energy storage system using phase-change material (PCM).

Syntax

TES(Model, ID, PPT, Charge, T_melt,
    Hot_In_state, Hot_Out_state,
    Cold_In_state, Cold_Out_state,
    Charging_time, Discharging_time,
    per_loss, Capacity=None, Calculate=False)

Parameter	Type	Description
Charge	str	'Charging' or 'Discharging'
T_melt	float	PCM melting temperature [K]
Charging_time	float	Duration of charging [hours]
Discharging_time	float	Duration of discharging [hours]
per_loss	float	Fractional loss (0–1)
Capacity	float/None	Storage capacity [J]

Charging Example

from ThermoSim import ThermodynamicModel
from ThermoSim.heat_exchangers import TES

Model = ThermodynamicModel()
Model.set_dead_state()

Model.add_point('Therminol66', 'h_in', P=1e5, T=573.15, Mass_flowrate=5)
Model.add_point('Therminol66', 'h_out', P=1e5)

TES(Model, 'PCM_Store', PPT=5, Charge='Charging',
    T_melt=500, 
    Hot_In_state='h_in', Hot_Out_state='h_out',
    Cold_In_state=None, Cold_Out_state=None,
    Charging_time=8, Discharging_time=4,
    per_loss=0.05, Calculate=True)

Discharging Example

Model.add_point('water', 'c_in', P=1e6, T=350, Mass_flowrate=2)
Model.add_point('water', 'c_out', P=1e6)

TES(Model, 'PCM_Discharge', PPT=5, Charge='Discharging',
    T_melt=500,
    Hot_In_state=None, Hot_Out_state=None,
    Cold_In_state='c_in', Cold_Out_state='c_out',
    Charging_time=8, Discharging_time=4,
    per_loss=0.05, Capacity=stored_capacity,
    Calculate=True)
