Abstract. The article presents a new solution for a protective heat-resistant men’s jacket with an increased level of air exchange, in order to maintain the physiological comfort of a person in conditions in a high-temperature environment. The work provides a systematization and analysis of constructive and technological solutions for models of anti-thermal clothing based on the principle of providing ventilated clothing space. An analysis of the design features of special-purpose suits for protection against high temperatures showed that the most common structural element for ventilation is a slit-like opening. The results of patent studies showed that the structural elements of ventilation are recommended to be located in places of the least likelihood of damage to the surface of clothes, but providing free air exchange. Based on the systematization of these physiological characteristics of a person, the most rational areas of ventilation in clothes were determined: coquette back + back surface of the sleeves. The effect of ventilation of the clothing underwear space is achieved by opening the ventilation hole during the dynamic movement of the upper extremities: bending the arm in the elbow joint. Based on the obtained data, a functional dependence of the horizontal cross-sectional area of the air inlet between the parts of the sleeve on the slope of the projected division line of the rear lower part of the sleeve is established. The largest cross-sectional area of the ventilation hole was determined when bending the arm in the elbow joint, taking into account the established ergonomically acceptable angle of inclination of the rear lower part of the sleeve. The established data are the basis for the development of the sleeve design of the new ventilation design of the thermal jacket. It was experimentally established that the proposed engineering solution of the jacket allows to reduce the temperature of human skin in the region of the front angle of the armpit by an average of 4.8 %, which confirms the effectiveness of the presented development and additional opportunities to increase the efficiency of the use of special heat-resistant clothing in the labor protection system at high temperatures.
