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
