Dear Trnsys users, 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 -18oC. 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 (-18oC), there will be ice
formed. Do you have any other idea on that? Do you think
Type88 and Type508 can work at low temperature such as around -20~-30oC?
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? Thanks in advance! Cheers, Ming |
