The article presents the results of the study of the ventilation device. A system of automatic control of the process of regulating air exchange in a residential area has been developed, which allows you to control an element of the actuator, which increases the productivity and efficiency of the ventilation device. An automated module of the process of regulating air exchange in residential buildings has been developed, designed to control the regulation of air exchange and its determination in residential buildings in different periods of the year. The software module implements recalculation of the main heat and humidity parameters of the air.
