[TRNSYS-users] No output from Type 74, CPC collector
Title: Message
Hi
everyone,
I am experiencing a
problem using type 74, the CPC collector. I have it connected to the type 109
(TMY2) weather reader with the following inputs:
-ambient
temperature,
-incident
radiation,
-incidence angle,
-zenith
angle,
-solar azimuth
angle,
-collector
slope
I am using axis
orientation mode 2. I also use a constant input fluid temperature and mass flow.
The problem I am
experiencing is a fluid outlet temperature that is slightly lower than the input
temperature (i.e. affected only by the thermal loss due to the temperature
difference to ambient). There is no heat transfer to the absorber tube although
there is radiation going into it.
If I use the same
weather data and input setup on any other collector model it works
fine.
Has anyone
experienced this before and maybe a solution to this?
Thanks!
Paul
