Sweating Thermal Manikin

Sweating Thermal Manikin can reflect the factors that affect the heat exchange between the human body and the environment, these factors include:

① The surface area of the human body covered by fabric and the surface area of exposed skin;

②The distribution of the clothing layer and the air layer on the surface of the human body (that is, non-uniformity);

③ Tightness;

④ Due to the increase of the heat dissipation area after the human body is dressed (that is, the clothing area coefficient);

⑤ Influence of product design;

⑥Changes in clothing characteristics (zippers are opened, headscarves are worn, etc.);

⑦ Differences in temperature (and heat dissipation) of different parts of the human body;

⑧The impact of human body posture (such as standing, sitting, lying down);

⑨The impact of human activities (such as walking, cycling);

⑩The Sweating Thermal Manikin test can reflect the real situation, because such a test can quantitatively describe the impact of the clothing system on the heat exchange between the entire human body and the environment.

Sweating Thermal Manikin will continue to be used to measure the thermal resistance and evaporative impedance of protective clothing systems. A useful tool in the development of protective clothing systems, Sweating Thermal Manikin can be used to evaluate protective clothing under steady state and transient conditions, as well as to predict wearer comfort (or thermal stress). Although the Sweating Thermal Manikin is easy to use, dummies, artificial climate chambers, computer control and data acquisition systems are expensive and complex to maintain, the Sweating Thermal Manikin is an important piece of equipment for protective clothing evaluation research and its research, development and application are of great practical importance. It is believed that with the cooperation of all relevant research institutions, the Sweating Thermal Manikin testing technology will be further developed in the near future.

It is of great significance to evaluate the comfort and performance of protective clothing systems. More and more standard test methods use a life-sized Sweating Thermal Manikin to test the performance of protective clothing systems. Walter Sweating Fabric Manikin was used to evaluate the fire resistance and airtightness of different types of protective clothing.
