The mathematical model of dynamic mode thermoexchange in a flat solar air heater
(SAH) is given. The reliability of the mathematical model is confirmed by the experience data. A
mathematical model of the dynamic mode of heat exchange in a solar air heater is obtained. A
comparison of experimental and calculated data shows their good convergence. The average
statistical deviations of the calculated and experimental data do not exceed ±11%. The reliability of
the mathematical model is confirmed by experimental data on the temperature regimes of SAH.
