Introduction The aim of the study is to find out, based on the project’s approach, the main components of the project on the research of the microclimate of industrial premises, and to substantiate, develop and apply a means of geometric analysis of the graphic dependencies of its parameters. A comparative analysis of the graphic dependencies indicates the significant effect of local exhaust ventilation on the character of the temperature field in the room. The comparative analysis of results makes it possible to analyze the insulation of isotherms, that is, the effect of local exhaust ventilation on the nature of their location in a cutting plane. The practical significance of the scientific results obtained in the work is to develop a new methodical approach based on the combination of physical and geometric modeling using a constructive device of applied multidimensional geometry, which can be an instrumental basis for the purposeful study of similar technological processes in the production premises.
