Sweating Thermal Manikin
Walter sweating manikins accurately replicate human responses to environmental conditions, crucial for optimizing thermal comfort. Other manikins have limited sweat glands, far fewer than humans (nearly 6 million), can't maintain consistent sweating, and are costly due to complex controls. Walter is the first affordable, accurate manikin using water and breathable fabric.
Application
Sweating mannequins are widely used in research on the moisture transfer properties of clothing and the microclimate conditions beneath garments. They are used to study the evaporative heat dissipation efficiency of clothing and to simulate sweating mechanisms. Sweating mannequins can be used to test the thermal resistance and moisture resistance of clothing, as well as to evaluate the non-evaporative heat dissipation performance of clothing.
The development of sweating mannequins has gone through several stages, from the first-generation static mannequins to the third-generation sweating simulation mannequins. The first-generation mannequins were used for static clothing thermal resistance testing, the second-generation mannequins expanded the evaluation of thermal and moisture performance, and the third-generation mannequins integrate computer technology to achieve precise temperature control and multi-environment simulation.
The applications of sweating mannequins also include studying the moisture transfer properties of clothing and the microclimate conditions beneath garments, as well as simulating sweating mechanisms. These mannequins can be used to test the thermal resistance and moisture resistance of clothing, as well as to evaluate the non-evaporative heat dissipation performance of clothing.
