earth with a thermal conductivity of 2.0 W/(m•K) has a U-value of just 0.02 W/(m 2•K), so the relevant... t is averaged out because the number of charging phases are the same as the discharging phases. Steady-state consideration of the heat flows is therefore qu... ne with increasing soil depth. Simultaneously, a phase shift takes place so that external air temperatu
