Virk, 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. kind regards, David
