Re: heat exchanger

Humberto,

I am looking for a detailed heat exchanger numerical
model for my thesis project. The first fluid
(typically hot water) flows through the tubes side,
and the second fluid (typically refrigerant) flows by
the shell side, during which it changes its phase.

I would like a model that takes the sensible and
latent heat exchange into account, considering a
negligible pressure drop.

The Type 5 and Type 91 heat exchangers are very
simplified for my purpose.


Just a comment: if you don't find what you are looking for in the components that are available (standard / Add-ons / TRNLIB / Users), you could consider using EES to develop your own model and test it in TRNSYS using Type 66 (if you don't know EES: http://www.fchart.com/ees/ees.shtml)

Using EES to develop a model offers the advantage that you just have to write the equations "the way you think of them" without having to pay attention to programming. It slows down the simulation compared to "pure TRNSYS" but it is usually not a problem when developing a model, and you can still create a new Type afterwards if you find out it is necessary.

Kind regards,

Michaël Kummert
