Is it possible to predict the outlet temperature of a vertical ground heat exchanger with knowing analytical equations like finite line source ?

We only know the entering temperature to the heat exchanger (T_in=0), it doesn't change with time, and also we have an analytical relation (see attached schematic).

Type 917 in TRNSYS TESS Libraries includes an Air-to-Water heat pump, but I've never used it in a model. I only use the water-to-water heat pump for my projects.

Reza Ghezelbash

thanks Dear Fred, i need the mathmatical model , i don't have TRNSYS TESS LIBRARIES

Reza,

Sorry for not getting back to you sooner. Please see the attached file for a mathematical model for a air-to-water heat pump.

Hope that helps.

Fred

thanks Fred for your good attached file.
