I am about six months into transport refrigeration and I wondered about a few minor things.
I have not yet went to uni but was wondering if all refrigeration cycles were the same.

E.G. walk in refrigeration, domestic refrigeration and factory refrigeration work similar to transport refrigeration?

Ofcorse the travle distance for the refrigerant will vary and the size of the coils. Most of the systems we work with have 42c/260psi (R404A) in the condeser. Does the pressure change (and so the temp.) to reach the distances?

Im guessing the refrigerant will also change?

How much varies when it comes to differant styles of systems?
