Dear Mr. Bradley,
I made my project of a
house with two floors and an attic which has a PCM layer
installed on the ceiling between second floor and attic in
TRNSYS 17. I used a type1270 that we bought a few years ago.
I have a number of problems I can`t solve.
- When I use Type1270b
(built-in component) it reports "fatal error in Trnsys" even
though the example from the HighRiseWithPCM folder works in
Trnsys17 that I have installed on my computer.
- When I use Type1270a
(custom component), the project can be run in Simulation
studio, but there seems to be no interaction between the
building and the PCM layer. The results indicate that the
temperature of the PCM layer is equal to zero during
simulation period of one year.
I connected all
components as it given in the example HighRiseWithPCM.
- Also, if I put that
the PCM melting temperature is lower than the solidification
temperature, simulation in SIMULATION STUDIO can be started.
But, if these temperatures are equal or the melting
temperature is slightly higher than the solidification
temperature (such as for example for coconut oil), then it
does not work.
Please help me find what
is causing this. I don't know what I did wrong.
I point up that we also
have a license for TRNSYS 18 and that I can install it if
the version of the program is the cause for some of these
problems.
Kind regards,
