Re: [TRNSYS-users] produce chiller

[David BRADLEY <d.bradley@tess-inc.com>]

Wahiba,
  Components that model the internal workings of a chiller were not available for Trnsys16 (or for Trnsys17). All of the Trnsys chiller components of which I am aware use a performance map approach (reading performance data from an external file) and are not first-principals models of the changes in refrigerant state within the chiller. In fact I am not sure that TRNSYS is an appropriate tool for modeling the internal workings of a chiller. I would develop such a model in a tool called EES (Engineering Equation Solver) (perhaps coupled with another tool called REFPROP) instead as they contain the equations of state that you will need for the various phases of your refrigerant in the chiller cycle.

  If you are looking for a model of how a chiller performs within a system instead of a model of the inner workings of the chiller then one of the performance map chiller models that were available in Trnsys16 may work for you.
kind regards,
 David

Hello,

what is the compenent (type) in trnsys16 that represent the  boiler(with inlet (for the NH3-H2O Solution) and tow outlet (one for NH3 vapor and the second one for H2O)? 

which componet (type) in trnsys 16 represent heat exchanger with two inlet (one for NH3 vapor, and the second one for H2O liquid) and one outlet (for the solution NH3-H2O)

?

we need this in order to produce chiller.

kind regards
