The factors that determine the conditions for creating a thermodynamic model when designing an air conditioning system for growing insects are analysed. The stages of building a thermodynamic model for the design of a subsystem for providing hygrothermal conditions for insect rearing are formed. The structure of the initial data for the construction of air treatment processes in thermodynamic systems with the provision of optimal technological parameters of the technocenosis. Using a thermodynamic model of the microclimate creation system in the d-h diagram of humid air, studies of heat and mass-humidity treatment processes provide information on the required load and volume of systems for providing abiotic factors. Using the method of graphical analysis, it is possible to determine the optimal methods of controlling the polytropic processes of preparing the air of the abiotic environment until it reaches certain temperature and humidity characteristics.
