i have two problems with TRNSYS 17.
1. I´m trying to make the maximum heating rate of an element (of Type 60c)
depending on the power produced by PV in three steps. Shold look like that:
If 1.5kW < PV-Power < 3kW then heating rate = 1.5 kW
else if 3kW < PV-Power < 4.5kW then heating rate = 3kW
else if PV-Power > 4.5kW then heating rate = 4.5kW
I´ve set the heating rate as a String variable which shold get the value
from a equation. but i don´t know how to update the equation in every time
step of the simulation.
2. Does anybody know what the external files of type 20 (dual source heat
pump) are? Unfortunatly ther is no example in the TRNSYS-Examples folder.
