The environment and ergonomics of clothing in the design of a human comfort system

Abstract

During the time of stay in the city outside the closed premises during the periods of seasonal cooling, for a human thermal protection is provided by clothing. Clothing for protection from the cooling environment in the city is considered comfortable if its weight and dimensions do not limit a person in a given route and specificity of movement and does not draw attention to their own thermal sensations (i.e., the thermal balance of a person does not go out of the biophysical norm). Effective smart thermal protective clothing requires the inclusion in the thermoregulation system of consideration of individual human activity, which to some extent depends on the weight of the garment. Paper shows the proposed schematic diagram of the concept of operation of the functional system of smart thermal protective clothing. On the basis of the developed models and established functional relations for the proposed structure of smart thermal protective clothing, studies of its thermal effect depending on the properties of the clothing have been carried out. The developed functional models of connections of input and output parameters of biotechnical system “man-clothing-environment” allowed to reveal regularities of influence of clothing parameters and its weight on thermal comfort of a person in it.
