Specification

The thermal manikin of an average human body shape capable of limbs positioning (motion of shoulders, elbows, knees and ankles) is employed for assessment of thermal comfort of individuals both indoors and outdoors (e.g. buildings, vehicle cabins). It can also be used to assess thermal insulation properties of clothing and equipment for sport or work activities. The manikin can be used to measure heat losses due to convection, radiation and conduction over 34 heated zones (face, head, chest, abdomen, back, arms, forearms, hands, hips, thighs, calves and feet); based on these values the total heat loss of the entire body can be obtained. The manikin is also provided with an adjustable breathing system (various inhalation and exhalation flow rates through either mouth or nose or both) and with filters, which allow to monitor a composition of the inhaled particles.

Technical parameters

• Average human body shape
• Operating temperature range from -20 to +50 °C
• 34 independently controlled zones
• 34 independently measured zones - surface temperature, heat flux
• Two air temperature sensors
• Relative humidity sensor
• Air speed sensor
• Breathing system
• Filter for monitoring of inhaled particles

Device applications

• Thermal comfort measurement - Inside vehicle cabins and building interiors a precise control of environmental parameters. The aim of measurements is to reveal the areas where draught or other causes can lead to thermal discomfort.
• Assessment of thermal resistance - It is necessary to verify thermal insulation capability of clothing or equipment for sport or working activities. The measurement values obtained can be further used for optimisation and CFD modelling of ventilation or air-conditioning systems in vehicle cabins and building interiors.

• in agriculture, where it is used in the optimization of breeding and growing conditions, e.g. checking the state of ripeness of cereal fields or subsequent control of the state of grain stored in granaries
• in healthcare, even a small temperature difference in the human body (for example 0.5 K) may indicate disease or other serious disorders of the body. It is most often used in oncology in the pathological process, in rheumatology in the detection of ligament and tendon diseases, in the field of neurology and gynecological tumors
