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.
