Sudden changes in air temperature and humidity have a negative impact on crop production. Modern methods of regulating the microclimate of greenhouse facilities are reduced to the simplest one - controlling the flow and temperature of air masses. The aim of this work is to create and test (verify the plausibility) a simplified model of the microclimate of a medium-sized greenhouse. The simplified greenhouse model takes into account the main processes that occur under the influence of external factors (air exchange, mass transfer, moisture transfer, heat transfer), and also takes into account the geometric and spatial characteristics of the object. Each test experiment involves determining the effect of only one parameter at fixed values of all other parameters. A simplified reference model of changes in microclimate parameters (temperature, air velocity and pressure) was developed using Ansys software. Using computer modelling of temperature fields and velocities, an analysis was carried out to determine the possibility of using the model in the control system. The microclimate characteristics were analysed when air pressure, velocity and temperature were stabilised. The results of the study and the developed model are suitable for use in control algorithms for the greenhouse mechatronic system to take into account cyclic daily changes in parameters.
