Abstract

The article describes a hardware and software complex for automatic control of the drying agent preparation process with specified temperature and humidity parameters. The hardware includes a single-board computer, temperature and humidity sensor, control boards for the refrigerator and flaps, communication boards. The software component of the complex includes modules for polling sensors, controlling the refrigeration machine, calculating the degree of flap opening, and managing data exchange. A mathematical description of the processes of heating, cooling, dehumidification, humidification and mixing of air flows is presented, which served as the basis for the visualization module in the form of an interactive I-d diagram that allows calculating the parameters of the processes of humidification, heating, cooling and mixing of the drying agent. The results of experiments on adiabatic humidification and heating of one section of a small-sized drying unit UPOR-M are presented.
