Mathematical model of automatic control of the temperature and humidity regime of a solar cell with a subsurface heat accumulator

Based on the analytical method, a mathematical model of the heat and mass transfer process in solar heat dryers in the greenhouse mode has been developed. The possibility of approximating complex transfer functions by simpler, convenient for practical purposes is shown. The resulting system of differential equations fully describes the heat exchange processes in the solar cell and heat accumulators. The delay time of the adjustable value in heat accumulators is not taken into account due to its insignificance compared to the time of transients.
