Heat Loss Calculation of Underground Central Heating Pipelines
Original language description
The article subject is the experimental temperatures measurements on the thermal areas surrounding the preinsulated district heating pipes, located below the ground surface. The heating pipes are located in to the sand filling. The results of the mentioned experiment are applied for supplementation and modification proposals of the equations used for determination of the heat losses from the heat pipelines. The article copes with the thermal conductivity of the pipe insulation material in dependence on the temperature, the thermal conductivity of the non-homogeneous surrounding filling material in the space around the pipe and the periodic function of the temperature at the specific depth of the semi-infinite space. The result is the design modifications of the conventional computational procedures and codes.
