Abstract

The article developed a mathematical model of the non-stationary mode of the solar greenhouse heating system based on biogas energy obtained from animal waste and solar energy, which makes it possible to calculate the heat recovery of livestock buildings. It has been established that the heat recovered from the livestock building can cover 16-34% of the heat load of a solar greenhouse with a working area of 180 m². A block diagram in static and dynamic mode was developed to calculate the mathematical model of heat balance "Livestock solar greenhouse complex" in the package MATLAB / Simulink. The results of the block diagram show that in the static state, the outside air temperature is 0 °C, the average solar radiation is 150 W/m², the indoor temperature of the livestock building is 18.8 °C, the internal temperature of the solar greenhouse rises to in 50 minutes 15,6 °C. As a result of the construction of the block diagram in a dynamic state according to the weather data of August 11, 2021, the temperature of the livestock building during the day is 7 °C, solar radiation - 388 W/m², livestock the temperature of the building rises to 30 °C and the temperature of the solar greenhouse to 34 °C.
