Hi all,

I'm simulating a solar thermal system with EnergyPlus.

The water temperature results which I obtain when simulating are above 100C in some nodes and some hours of the day, probably because I'm using a large number of collectors.

About this I would like to know if someone could help me:

1) Is E+ considering water vapor in these nodes (above 100C) or simply water liquid at a greater pressure?

2) Is there a possibility to avoid that the water reachs 100C in the collector loop? (I've tried to set "AvailabilityManager:HighTemperatureTurnOff" in order to turn off the loop if temperature reaches 100C but I have nodes with temperatures above 100C so far).

Thanks in advance,

Paulo Ara.
