Hello. Does anyone have experience with modelling horisontal soil heat systems where solar heat is gathered. Typically a long hose/tube laid out horisontally approx 1 m below the ground surface through which a heat transporting fluid is pumped. The heat is retrieved fro the fluid using a heat pump. The temperature will increase along the length of the hose.
I Suppose the critical modelling parts will be heat exchange through the soil surface, incoming solar radiation etc. and the horisontal layout of the system, but would like to hear about any experience in this field.
Best regards Christian.
