Dear Michael, 
Thank you very much for your advice, I will let you know what I've done and how it works out.

Apparently nobody has proposed a component to simulate your heat 
exchanger. Depending on the level of detail you need and what you are 
interested in (i.e. a complex system using the heat exchanger or the 
heat exchanger itself), you can either use some tricks to use existing 
components (e.g. Type 5 with a very high Cp for one fluid), use simple 
equations in your TRNSYS file, or develop a new component. If you want 
to develop a new component and you have the physical equations 
describing the heat exchanger, you could consider using Type 66 and 
implementing your equations in EES at first, so you can concentrate your 
effort on modeling and not coding. If you are satisfied with the 
behavior but need faster simulations, you can then rewrite the EES 
equations in Fortran.

I hope this helps,
