[TRNSYS-users] Type 557 number of radial regions, and number of vertical regions?

[metkell yebiyo]

Dear Trnsys Users,

I am looking at the effect of heat extraction and dissipation to the performance of heat pump and 
also to the ground temperature distribution over time. 

I am using the ground heat exchanger type 557 to simulate the ground temperature variation.

I have 176 energy piles, 26m deep.
10 piles connected in series.

so my question is:

What is the number of radial regions, and number of vertical regions?
how do I find out how many radial and vertical regions I need?


Regards,
Metkel
