I imagine that you have already checked this but does the simulation
result file give you any indication as to why it stopped running (too
many warnings, an error, etc.) or does the simulation just get hung up
at some point?<br>
Kind regards,<br>

style="font-size: 10pt; font-family: Arial;" lang="EN-US">I am working
on the simulation of a refrigeration
system on the refrigerated transport. I used Type88 to model the
refrigerated
space and Type508a to model the cooling coil inside the refrigerated
space. The
temperature of the refrigerated space is at -18<sup>o</sup>C. The model
can
work. However, sometimes when I change some parameters, such as the
flow rate
of the pump and the fan, the simulation will stop after running for a
while. I
guess it is maybe because of the low temperature. In real application,
there
will be water condensed on the wall of the refrigerated space and also
the
cooling coil. And at the low temperature (-18<sup>o</sup>C), there will
be ice
formed. <o:p></o:p></span></font></p>

any other idea on that? Do you think
Type88 and Type508 can work at low temperature such as around -20~-30<sup>o</sup>C?
Can these two components solve the condensing problem? Is there any
other
people working on the low temperature simulation? Have you ever come
across any
problems?<o:p></o:p></span></font></p>
