[TRNSYS-users] Parameters for Type557a

[a8304506 at graduate.hku.hk]

Hello, everyone.

I try to use Type557a to simulate the performance of borehole ground heat
exchangers in a multi-layer ground.  However, I don't know what values I should
use for the store thermal conductivity and volumetric heat capacity (Parameters
9 & 10).  Should I input the average values of all the ground layers?  It seems
that these two parameters influence the outlet fluid temperature substantially.
 Please advise.  Thank you!
