Ravindra, The answer to your question depends somewhat on which models you are talking about. Most TRNSYS models assume that the fluid properties (usually density and specific heat) are constant over the temperature range that they will experience during the simulation. The assumption goes all the way in to the derivation of the equations used in the model. If you need a piece of equipment whose working fluid's properties must change with temperature then you have to rederive the basic equations and rewrite or revise the model. There are some models in the TESS High Temperature Solar library that allow you to enter coefficients that describe how the properties of the working fluid vary with temperature. kind regards, David On 03/15/2016 07:36, v ravindra wrote:
