Re: [TRNSYS-users] Suction line heat exchanger component



Ravindra,

  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.

  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).

kind regards,

 David
