[TRNSYS-users] SDHW example TRNSYS

[Rm Chemilo via TRNSYS-users]

In this attachment file, I tried to calculate hourly thermal efficiency of
solar collector by using this two equation [image: Inline image 3] and [image:
Inline image 4]. But after comparing the result, why the hourly efficiency
different?

And also please check "Comparison Energy balance" sheet. I don't understand
why q gain from solar collector has different value with qin storage. even
though in the example there is no heat exchanger between solar collector
and storage.


Thank you.
