Abstract: The article analyzes modern technologies for keeping pigs, in particular the prospects for using mechatronic systems to ensure microclimate in pig houses. It was determined that deviations in microclimate parameters negatively affect the health, reproductive functions and growth of pigs, which leads to a decrease in the profitability of farms. An algorithm for the operation of a mechatronic system with adaptive air ventilation and energy-saving technical means has been developed, the parameters of which have been optimized using software modeling. Based on the adopted design and technological scheme of the mechatronic system for ensuring the microclimate of pig houses and the theoretical and experimental studies of its elements, an algorithm for its operation has been developed. The developed algorithm is implemented in the created simulation of the microclimate of a pig house in the Simcenter Star-CCM+ software package. According to the modeling, the temperature dynamics at each stage of the passage of the air flow through the developed microclimate system in the pig house throughout the year were obtained. The temperature of the air flow after passing through the ground heat exchanger and the indirect evaporation type heat exchanger approaches the values of zootechnical requirements. The process of cooling the air to a given temperature (22 °C) occurs without the use of additional air conditioning systems, and heating the air to a temperature of 18 °C requires additional switching on of heating elements. The dynamics of power consumption of the developed and classical microclimate systems in a pigsty for 16 machines was obtained. The obtained annual energy consumption for the developed microclimate system is 17528 kWh, which is 28.6 % less than the classical system (ventilation with a ground channel and a heating and air conditioning heat exchanger).
