Automotive air conditioning thermal comfort dummy

Product description.

For a long time, the comfort evaluation of automotive air conditioning has mainly drawn on the evaluation method of building air conditioning comfort, and there is not yet a recognized comfort evaluation system for automotive air conditioning. In addition, when evaluating the comfort of automobile air conditioning (HVAC) at home and abroad, most of them use the human thermal comfort evaluation index applied to CFD simulation and calculation. However, the method involves a large number of numerical calculations, the accuracy of the results is not high, and the method cannot accurately assess the physical state of the person being measured and cannot achieve stable controllability.

Technical realization elements.
The automotive air conditioning thermal comfort test dummy can simultaneously determine the thermal conditions of various parts of the human body in the external environment, thereby providing an accurate assessment of the environmental factors inside the vehicle, and also effectively avoiding errors due to individual differences in the human body.

Product features.
Wind speed, temperature, humidity, thermal radiation detection at the same time
Intelligent software online system for real-time monitoring, supporting WiFi and wired transmission.
The interior of the human body model is hollow, all joint parts are connected with metal parts, and the angle can be set arbitrarily. Simple and easy installation and disassembly of sensors.

Product application.
Applicable to the comfort test of the interior and indoor air conditioning system of a car. The system makes a comprehensive evaluation of the comfort of the interior of a car and a specific space through the simultaneous measurement of wind speed, temperature, humidity and thermal radiation.

Advantage.
Overcomes the drawbacks of existing automotive air conditioning (HVAC) comfort evaluation methods, and can simultaneously measure the thermal conditions of various parts of the human body in the external environment, so as to make an accurate assessment of the environmental factors in the interior of the vehicle, while also effectively avoiding errors arising from individual differences in the human body.

Characteristics.
A complete set of equipment for measuring the effect of heat and air conditioning design on passenger comfort in the interior of a car/truck.
Sensors arranged in a matrix outside the body measure air velocity, temperature, radiant heat flow and relative humidity.
Average Western or Asian male body size.
The mannequin has shoulder, hip, knee, elbow and ankle joints.
The closed not shape of the linked fingers is curved, gripping the car side steering wheel posture.
The flattened thigh surfaces (back and bottom) approximate the shape of a human thigh squeezed after sitting.
Radio-electron controlled transmission.
