[esp-r] Re: Underground temperature?

[Bob Irving]

Underground temperatures below 10m are usually reckoned to be the same  
as the average yearly air temperature.

There is a formula in Labs, K "Underground Building Climate". Solar  
Age, Vol 4 Part 10, 1979 reproduced in Harris, D J "Ground  
Temperatures in Britain". International Journal of Ambient Energy, Vol  
27, No 3, which relates underground temperature to Mean annual  
Temperature, depth, time of year in days, amplitude of surface  
temperature, thermal diffusivity, which gives a sort of sine wave.   
Also in Jenkins, D. P., Tucker, R., & Rawlings, R. (2009). Modelling  
the carbon-saving performance of domestic ground-source heat pumps,  
Energy and Buildings.
