Abstract. The role of air layers in ensuring rational heat exchange of a person is shown. A promising solution for ensuring a rational thermal state in industrial conditions at elevated temperatures is revealed — the use of ventilated clothing. It is shown that the effectiveness of such sets is ensured by air movement in organized and stabilized air layers, which provides additional heat removal from the human body when air moves under the clothes. The design of a set of ventilated clothing for vegetable growers working in industrial greenhouses at elevated temperatures is revealed. A comparative study of heat and mass transfer processes in packages of traditional and ventilated vegetable grower clothing was conducted, in which the influence of the type of air layer and the material of the underwear on the intensity of these processes was assessed. As a result, it was found that for short-term work in an industrial greenhouse, it is preferable to use underwear made of knitted fabrics based on natural raw materials. For long-term work, underwear made of knitted materials based on synthetic fibers is preferable to use. It is shown that such products, despite some reduction in ergonomics, contribute to more intensive heat removal from the worker’s body.

The differences in heat and mass transfer processes in traditional clothing packages with unorganized isolated air layers and ventilated clothing sets with stabilized air layers that communicate with the environment are shown. It is established that in all experiments ventilated clothing contributes to better heat and moisture removal from the human body in comparison with traditional clothing. The obtained data experimentally confirm the theoretical concepts of higher efficiency of ventilated clothing in conditions of elevated temperatures.
