Automobile Air Conditioning Thermal Comfort Dummy
Background Technology
For a long time, the evaluation of the comfort of automotive air
conditioning has mainly relied on the evaluation methods of
building air conditioning comfort. There is still no universally
recognized evaluation system for the comfort of automotive air
conditioning. Additionally, when conducting comfort evaluations of
automotive HVAC (Heating, Ventilation, and Air Conditioning) at
home and abroad, most of them apply the human thermal comfort
evaluation indicators to CFD simulation and calculation. However,
this method involves a large amount of numerical calculations,
resulting in low accuracy of the results, and this method cannot
accurately assess the physical condition of the tested individuals,
nor can it achieve stable controllability.
Technical Implementation Details
The automotive air conditioning thermal comfort test dummy can
simultaneously measure the thermal conditions of various parts of
the human body in the external environment. This enables the
assessment of the indoor environmental factors in the vehicle, and
at the same time effectively avoids errors caused by individual
differences among humans.
Product Features
Wind speed, temperature, humidity and heat radiation are all
detected simultaneously.
The intelligent software online system conducts real-time
monitoring and supports WiFi and wired transmission.
The interior of the human model is hollow, and each joint part is
connected by metal parts. The angle can be set arbitrarily. The
installation and removal of the sensors are simple and convenient.
Product Application
Suitable for testing the comfort level of air conditioning systems
in vehicles and indoor spaces. The system measures wind speed,
temperature, humidity, and heat radiation simultaneously to provide
a comprehensive evaluation of the comfort of the vehicle interior
and specific spaces.
Advantages
It overcomes the drawbacks of the existing comfort evaluation
methods for automotive air conditioning (HVAC), enabling the
simultaneous measurement of the thermal conditions of various body
parts in the external environment. This allows for an accurate
assessment of the indoor environmental factors in the vehicle,
while also effectively avoiding errors caused by individual
differences among human beings.
Features
A complete set of equipment used to measure the heat inside
cars/trucks and the impact of air conditioning design on passenger
comfort.
The sensors arranged in a matrix on the human body can measure air
velocity, temperature, radiant heat flow and relative humidity.
Average body types for Western or Asian men.
The human model has shoulder joints, hip joints, knee joints, elbow
joints and ankle joints.
The interlocked fingers have a curved shape, resembling the posture
of grasping the side steering wheel of a car.
The flattened thigh surface (back and bottom) is nearly the shape
that the human thigh assumes after sitting down and being
compressed.
Wireless electronic control transmission.
