[TRNSYS-users] SDHW example TRNSYS

[Rm Chemilo via TRNSYS-users <trnsys-users@lists.onebuilding.org>]

Dear all,

I want to ask several questions about TRNSYS example solar domestic hot water (SDHW).

- Why the outlet temperature of solar collector (type 1b) same as temperature ambient when there is no mass flow rate and irradiance. As you can see in the table below, ToColl = Tambient.

- How TRNSYS calculate the outlet temperature of the solar collector if there is no mass flow rate, but only the irradiance available?

Thanks.
