Heat transfer processes that occur when working the ground-air heat exchanger
of geothermal ventilation system are considered in this article. The heat balance in
the elementary volume of ground-air heat exchanger is proposed on the basis of
thermophysical processes. The main factors that affect the process of heat transfer
between the outside air and soil was been determined. Initial conditions, which
can be used in mathematical and physical modelling of horizontal ground-air
heat exchangers for geothermal ventilation systems were selected article presents
the experimental study for determining the intensity of radiant energy in the zone
irradiated by infrared heaters with their parallel arrangement in relation to the
distance between them.
