[TRNSYS-users] Forcing Function Type 14h problem

[Shofolahan, Idris Adewale]

Hi there,


I'm working on solar water heating system.I wanted to test the performance of the weather file before using it, by replacing it with the generic forcing function type 14h to keep the beam radiation on the tilted surface of component type 538 . I compared the outlet temperature with and without the forcing functions type 14h.

[cid:9d5acee5-8ec9-4e58-8fe3-e212968a31db]


I plotted the ?output temperature on the online printer,but the model without the forcing function gave an output temperature of 20.8 degrees while output temp. of the model with the forcing function was 15.8 degrees. Find screenshot of the two above.  What is the reason for the difference in the output temperature of the models?


Regards

Idris
