The current article uses a two-dimensional numerical model to represent the results of theoretical studies of the heat exchange in the soil massif during the operation of a shallow horizontal soil heat exchanger. The analysis of literature sources showed that one of the important conditions for the effective operation of a shallow-soil heat exchange is its rational design parameters, such as the total length of the pipeline, the diameter of the pipe, the distance between the axis of the adjacent pipes, the depth of the heat exchanger placement, etc. A two-dimensional heat exchange model in the soil mass was developed, which made it possible to investigate the operation of a shallow horizontal soil heat exchanger. It was found that the step between the axis of the adjacent pipes of the multi-loop heat exchanger, which is 0.95 m, is optimal when creating a shallow horizontal soil heat exchanger in the soil conditions of Kyiv.

Experimental research of heat transfer through heat-insulated wall enclosure structures

The article provides an experimental analysis of the behavior and changes in thermophysical properties of the thermal insulation systems most commonly used in construction during the entire life of the buildings. Experimental data on temperature fluctuations and distribution of heat flow density of a thermally modernized section of a wall-enclosing structure insulated by various methods for 6 years were obtained and the values of the actual coefficients of thermal conductivity of various heat-insulating materials were compared in the first approximation. The need to assess the influence of the service life on the thermophysical properties of heat-insulating materials used in the thermal modernization of buildings of various purposes is experimentally substantiated.
