I have a simple query related to TEMA class selection for shell & Tube heat echanger handling R134a refrigerant.

exchanger is a flooded type, where shell fluid is refrigerant R134a and tube side fluid is water.
actually we are referring TEMA "C" class for design flooded cooler, but we have a query to design the same for TEMA "R" class.
as R belongs to petroleum related process and C for general appication.

Are we following the correct class or we can consider the R class for design also ( results increase cost)
