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.
