[TRNSYS-users] Suction line heat exchanger component

[David BRADLEY via TRNSYS-users]

Ravindra,

   Models for the expansion valve and heat exchangers for vapor 
compression cycles don't exist in TRNSYS as far as I am aware. In order 
to write such a model you would need to know what refrigerant is being 
used in the cycle and you'd need a routine to give you refrigerant 
properties.

   I am not sure if TRNSYS is the right tool to use to model a vapor 
compression cycle. Typically we work with systems in TRNSYS that have 
transient behavior on the order of a minute or longer. The transients in 
the individual components of a vapor compression cycle are much shorter 
than that. At one minute intervals such a refrigeration cycle looks 
quite steady state and so we typically use performance maps to model 
them. When I need to look inside the cycle, I typically use a program 
called EES (Engineering Equation Solver).

kind regards,

  David
