[TRNSYS-users] Problem with alkaline water electrolyzer, Type 160

[Moritz Gramiller <ee19m003@technikum-wien.at>]

Hello,

I am using the alkaline water electrolyzer, Type 160, with the following
specifications:

- electrolyzer current (calculated from the difference of production and
demand of my PV-System, if positive):
abs(Power_W)/abs((gt(V_EL,0.5)*(V_EL))+((1-gt(V_EL,0.5))*1))
- cooling water inlet temperature (temperature of my heat grid, range from
-7°C to 48 °C)
- cooling water inlet flow rate (from pump, Type 110, 50 kg/h)

The problem is that the electrolyzer generates too much heat (output heat
generated + heat of cooling water outlet temperature), the thermal flosses
are not in balance.
Please see the attached flowchart (Energy in MWh)

Thanks in advance for any help.
