The invention relates to tools of industrial protection used in the metallurgical industry when operating under conditions of exposure to variable elevated temperatures and contaminated with substances harmful to human respiration and activity.

The purpose of the invention is to improve working conditions by automatically controlling the temperature and the amount of air supplied to the area during sudden changes in the ambient temperature and the functional stress of the body during labor.

The drawing shows a protective suit, a general view.

The protective suit contains a jacket with a helmet 1, trousers 2, a collector 3, thermoelectric converters 4, electrodes 5, electrical wiring consisting of propod 6, plug connections 7 and 8, cables 9 and 10, individual air conditioning 11, an actuator 12, air supply hose 13, two-channel automatic regulator 14.

Thermoelectric transducers 4 are installed on the inside of the suit in the chest area — the place where air enters the sub-space, in the wrist and ankle joints — the most distant places from, collector 3, and in the neck — the most abundant sweat. The installation of electrodes 5 on the hands of two hands makes it possible to obtain an electrical signal corresponding to the lead of the electrocardiogram.

Before starting work on the hands, electrodes 5 are installed, the collector body 3 is connected to a fixed clamp on the jacket 1, cables 9 and 10 are connected via plug connectors 7 and 8 to the internal system of wires 6 and to the actuator 12 of the individual air conditioner 11. The manual shutter valves of the collector 3 are installed in a position that ensures that no fresh air can be supplied for breathing in a quiescent state of air to a specific worker. The automatic regulator 14 through the IC: 11nolnyr1 mechanism 12 sets the set air temperature, which is applied to the individual air source II, into a number of choices 3.

15, the air from the external air line enters the individual air conditioner 11 and then into the collector 3. From the collector 3, the air enters the perforated tubes located inside the suit between the external heat-resistant and internal breathable fabrics, and then through the breathable fabric - into the underwear one. space. From the suit air enters the environment through the sleeves of the jacket, from under its lower part and through the bottom of the trousers. When the pressure in the external air line changes, the amount of air supplied to the subdomain space is kept constant by changing the gap between the self-regulating flap and the inner collar of the nozzle at the entrance to the individual air conditioner 12.

The temperature change in the suit's suitcase space due to an increase (decrease) in ambient temperature and body heat generation during operation is perceived by thermoelectric converters 4 and through internal wires 6, plug connection 7 and cable 9 electrical signals are fed to automatic controller 14 summed in the measuring unit, the resulting total electrical signal is compared with the basic signal output by the setpoint device, the difference signal through the feedback feedback device It connects via cable 10 and through plug-in connection 8 to an expe- rience (a pincer mechanism 12, which operated, regulates the operation of the individual air conditioner 11 and, as a result, the temperature of the air supplied to the space.

The change in the functional voltage of the body during labor changes the potential difference on the surface of the hands, is recorded by electrodes 5, information about which is integrally reflecting muscular, braking, neuro-emotional state and the associated heat release of the organism and the minute volume breathing, steps into the automatic controller 14 through the wires 6, the rod connection 7 and the cable 9, where, and Tgch with the base signal, ps luchenshyyyy n |) and this is the difference signal ninnyuaei UP
