Moritz,

 If you are using Trnsys18 then please send your project to your distributor so that they can have a look in detail at what is going on.

kind regards,

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.
Regards
Moritz, MSc. Student in renewable energy systems.
