HEAT PUMP USING SUBSOIL WATERS AS LOW TEMPERATURE HEAT SOURCE
Problems of the Regional Energetics, 2015 One of the basic directions of perfection of heat supply systems is the tendency of transition to the low-temperature heating systems based on application of heat pump installations. We consider heat supply system with heat pump installations using subsoil waters.

Estimating the Soil Temperature Profile from a single Depth Observation: A simple Empirical Heatflow Solution [PDF]
, 2008 Two field data sets are used to model near-surface soil temperature profiles in a bare soil. It is shown that the commonly used solutions to the heat flow equations by Van Wijk perform well when applied at deeper soil layers, but result in large errors ...
