Streszczenie
This paper describes a process for the non-stationary heat transfer that occurs between the vertical ground heat exchanger, surrounded by grout and the surrounding ground. Mathematical model of this phenomenon and its exemplary solution using the method of elementary balances were presented. Numerical calculations were performed using Mathcad. As a result, the set temperature field is formed in the wall of the heat exchanger, in the grout and also in the ground surrounding the U-tube and the amount of heat extracted from ground in the case of not including the occurrence of filling and using a variety of commonly used grouts.
