Description

The invention relates to methods for manufacturing personal protective equipment for people against temperature effects under high or low temperature conditions.

The purpose of the invention is to improve the quality of a suit by providing a uniform temperature effect on the surface of the body.

The proposed method for manufacturing a suit for protection against temperature effects is implemented as follows.

The overalls are made of parts made of a multilayer package comprising an outer layer 1, a middle layer 2 and an inner layer 3. The inner layer 3 is formed as a corrugation through the length of the part. The corrugation step L is chosen, for example, 0.04 m, height 0.03 m, g 0.01 m. The consumption of material for the formation of a system of channels in the form of corrugations is determined by the equations:

S Si + 0.04 m;

The layers are joined in the protrusion zones of the corrugation of the middle layer by gluing or piercing. Thus, temperature regulation is carried out evenly over the entire contact surface of the human body with the inner layer of the suit, and relatively large sections of the channels formed by the middle layer significantly improve the performance of the cooling (heating) system.

At the same time, the outer layer of a three-layer bag is made of a hermetic heat insulating material, and the middle wavy and inner flat layer is made of hermetic heat-conducting materials.

When the number of corrugations equal to 10 Si 0,324 m, S 0,364 m.

The layers of the package obtained are pairwise interconnected in the zones of projections of the corrugations of the middle layer 2 by gluing or thread seams 4. The corrugations of the middle layer 2 thus form, together with the outer 1 and inner 3 layers, the through channels 5 for supplying the heated or cooled agent , and the inner layer 3 is in direct contact with the surface 6 of the human body. The outer layer 1 is made of a hermetic heat-insulating material, and the inner layer 3 is made of a hermetic heat-conducting material.

Sections of the multilayer package in the places of the armhole, neck, bottom of the sleeves, waist and bottom of the product are closed with an airtight flexible channel 7, which forms the inlet 8 or outlet for the refrigerant that is common to all the pipelines of this part.

The upper part of the overalls is equipped with input 9 and output 10 circuits, and the lower part with input circuit 11 and output circuits 12. The output circuits of the upper and lower parts of the overalls are interconnected by pipelines 13. Supply and discharge of the heated (cooled) refrigerant are carried out through pipelines 14 and 15 and the pipeline 16 with an injection-suction compressor device 17, simultaneously performing heating (cooling) of the spent refrigerant to a predetermined temperature.

Heated (or cooled) refrigerant from compressor device 17 through pipelines 14 and 15 under pressure is fed into the inlet circuits 9 and 11 of the upper and 5 lower parts of the overalls, then it flows from the circuits into the channels formed by the middle layer, and through the inner layer 3 heats uniformly (cools) the entire surface of the human body covered

0 overalls. After heat exchange, the spent refrigerant enters the output circuit 10 either directly from the channels or (for the lower part of the overalls) through circuits 12 and pipelines V3. From the weekend

5 circuit 10 through line 16, the spent refrigerant is sucked off by the device 17 to restore the temperature.

The use of the invention allows uniform thermoregulation of the entire surface of the human body, covered with a suit, and the use of relatively large circulation channels of the refrigerant allows to increase the system performance and thereby increase

5 temperature limits for the operation of the protective suit, which increases usability.
