Product Description:

For a long time, the comfort evaluation of automobile air-conditioning mainly draws on the evaluation method of building air-conditioning comfort, and there is no recognized comfort evaluation system of automobile air-conditioning. In addition, when evaluating the comfort of automotive air conditioners (HVAC) at home and abroad, most of the evaluation indicators of human thermal comfort are applied to CFD simulation calculations. However, this method involves a large number of numerical calculations, and the accuracy of the result is not high, and the method cannot accurately assess the physical state of the tested person, and cannot achieve stable controllability.
 
Technical realization elements:

The thermal comfort test dummy for automobile air-conditioning can simultaneously measure the thermal conditions of various parts of the human body in the external environment, thereby accurately assessing the environmental factors in the car interior, and effectively avoiding errors caused by individual differences in the human body.
 
Features:

Simultaneous detection of wind speed, temperature, humidity, and thermal radiation
Intelligent software online system real-time monitoring, support WiFi and wired transmission;
The interior of the human body model is hollow, and all joints are connected by metal parts, and the angle can be set arbitrarily. The installation and disassembly of the sensor is simple and convenient.
 
Applications:

It is suitable for the comfort test of the car interior and indoor air conditioning system. The system makes a comprehensive evaluation of the comfort of the car interior and specific space by measuring wind speed, temperature, humidity and heat radiation at the same time.
 
Advantage:

Overcome the shortcomings of the 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, thereby accurately assessing the car interior environmental factors, and effectively avoiding individual differences due to the human body The resulting error.
 
characteristic:

A complete set of equipment used to measure the influence of heat inside the car/truck and the air conditioning design on passenger comfort.
Sensors arranged in a matrix outside the human body can measure air speed, temperature, radiant heat flow and relative humidity.
The average body size of Western or Asian men.
The human body model has shoulder joints, hip joints, knee joints, elbow joints, and ankle joints.
The retractable shape of the connecting fingers is curved, and it grasps the posture of the side steering wheel of the car.
The flattened surface of the thighs (back and bottom) is almost the shape of a human thigh after sitting down.
Wireless electronic control transmission.
 
The main parameters:

Communication method: wireless wifi/wired
Dummy material: FRP
Air temperature measurement range: -20°C to +70°C
Calibration accuracy: +/- 1.0°C
Display accuracy: +/- 0.1°C
Air velocity measurement range: 0.1-5.0 m/s
Temperature compensation range: -20°C to +70°C
Radiation sensor (standard) Measuring range: close to zero to >2,000 W/m2
Radiation sensor (bispectrum) Wavelength: 1-20 ?m total response, plus 0.2-3 ?m solar response
Relative humidity 0 to 95% RH, non-condensing 

Configuration:

Lightweight epoxy carbon fiber shell.
It includes a dummy body, a sensor element, a data collector, a data processing unit, and a data storage unit. The dummy body is provided with joints on the shoulders, hips, knees, elbows and ankles.
The arm of the shoulder joint can be moved out of the torso and can reflect various driver's postures in a wide range.
The body can be divided into two parts at the waist, making it easy to fit into the vehicle for testing.
The sensor of the surface device can measure air temperature, flow velocity, radiant heat flow and relative humidity.
The sensor protection cap can damage the temperature and pore flow sensor during transportation and fixing.
Even the finger-shaped thighs that cannot be retracted and flattened are designed to be conducive to airflow.
The control element includes wireless transmission through the IEEE802.11 network.
The power and data cables are connected to the side of the mannequin.
The vehicle simulation program can display CAD model drawings.
Multiple mannequins can be connected to a data system.
Contains computer and control software.
