[TRNSYS-users] Type 557: Initial surface temperature

[knut.erik.enerstvedt@niva.no]

Dear TRNSYS users,

I have a question about the Type 557
Vertical U-Tube Ground Heat Exchanger, the parameter called "Initial
surface temperature": I believe that the ground surface temperature
is usually close to the average air temperature for a particular time of
year. If I start my simulation in January, should I set the "initial
surface temperature" parameter to the average air temperature (with
a minor adjustment for ground vs. air) in January for my location?

Best regards,
Knut Erik------------------------------------------------------------------------------------------------------------
