Freeze Protection

Hi I modeling a process heat parabolic trough and a chose Therminol VP-1 as a HTF, I chose a 40 C for freeze protection temp, 90 and 350 as a loop inlet and outlet HTF tem. In the summary I get the annual thermal freeze protection equal zero. Is that possible?

Thank you.

Dear Mahdi,

You can look at the field temperature data in the results to see whether the temperatures fall below the freeze protection temperature to confirm those results.

Best regards,
Paul.
