<p>Ravindra,</p>
<p> 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.</p>
<p> 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).</p>
<p>kind regards,</p>
<p> David</p>
