<p>Virk,</p>
<p> The absorption chiller models in Trnsys are based on performance
maps. If you know the machine's cooling capacity and COP as a
function of the inlet chilled water, hot water/steam etc., and
cooling water inlet temperatures then the working refrigerant
doesn't specifically matter (it's impact is built into the
performance maps). If you do not have performance data then you'll
need to write a model. Connecting to EES via Type66 is certainly
an option if EES has the refrigerant properties that your model
will need. Another alternative is that there is a Trnsys kernel
function that allows Types to call a set of routines called
CoolProp. That may also be an option. My advice would be to work
out how you'd like to model the absorption chiller (ie determine
what your algorithms are going to be). Once you have a good sense
for how your model functions and what resources it needs (Matlab
routine, EES properties, python resources, Excel etc.) then it
would be a relatively easy decision as to how to go about
implementing the model in Trnsys.</p>
<p>kind regards,</p>

I want to model absorption chiller with different refrigerant
pairs? Could you please guys guide me how to do this in TRNSYS?
Initially i am thinking to link EES with TRNSYS (not sure if it
is right approach). If someone could guide in detail, it will be
much appreciated. </div>
