Thermal manikin analyses environmental and heat comfort

20. February 2012

Thanks to NETME Centre project, Division of Power Processes and Environmental Engineering acquired unique product, the so called Thermal Manikin (Newton Thermal Manikin System). Thermal manikin with average human body size and various optional positions of limbs (jointed shoulders, elbows, knees and ankles) evaluates thermal body comfort in indoor and outdoor environments (buildings, vehicles) along with evaluation of thermal insulation properties of garment for sports and working activities. Thermal manikin helps measuring heat loss from convection, radiation and conduction in total of 34 heated zones (cheeks, head, chest, abdomen, upper back area, lower back area, upper arm, forearm, hand – all left and right, hips, thighs, calf and feet – left, right, front, backside). Heat loss of the whole body is determined using acquired data from the manikin. Thermal sensation and thermal comfort of a simulated person are subsequently determined by weighted average of the zones. Manikin is only the fifth product of a kind in European laboratories; it will be widely used in collaboration with Škoda Auto automobile company and Volkswagen in Germany for development of control systems of automobile air conditioning. Manikin is equipped with adjustable respiration device (mouth and/or nose inhalation and/or exhalation) with filters for aerosol capture. Filters monitor transport of dust particles in the cabin area, which helps to design technologies to reduce their negative impact. Manikin is also supplied with an in-built virtual model of human thermal comfort which simulates blood circulation, perspiration, respiration, muscle contraction, vasodilatation and vasoconstriction in hot and cold environments.

NETME Centre was built with the financial support from the Operational Programme Research and Development for Innovations within the project NETME Centre
