Automotive air conditioning thermal comfort dummy

Automotive air conditioning thermal comfort dummy

Background technology:

For a long time, the comfort evaluation of automotive air conditioning has mainly relied on the evaluation methods of building air conditioning comfort, and there is no recognized evaluation system for automotive air conditioning comfort. In addition, when evaluating the comfort of automotive air conditioning (HVAC) both domestically and internationally, most of them use the human thermal comfort evaluation index to be applied to CFD simulation calculations. However, this method involves a large amount of numerical calculations, and the accuracy of the results is not high. Moreover, this method cannot accurately evaluate the physical condition of the tested person and cannot achieve stable controllability.

Technical implementation elements:

The car air conditioning thermal comfort test dummy can simultaneously measure the thermal conditions of various parts of the human body in the external environment, thereby evaluating indoor environmental factors and effectively avoiding errors caused by individual differences in the human body.

Product features:

Simultaneous detection of wind speed, temperature, humidity, and thermal radiation

Intelligent software online system for real-time monitoring, supporting WiFi and wired transmission;

The interior of the human body model is hollow, and all joint parts are connected by metal parts, and the angle can be set arbitrarily. The installation and disassembly of sensors are simple and convenient.

Product application:

Suitable for testing the comfort of car interior and indoor air conditioning systems, the system comprehensively evaluates the comfort of car interior and specific spaces by simultaneously measuring wind speed, temperature, humidity, and thermal radiation.

Advantages:

Overcoming the drawbacks of existing comfort evaluation methods for automotive air conditioning (HVAC), it can simultaneously measure the thermal conditions of various parts of the human body in the external environment, accurately evaluate indoor environmental factors, and effectively avoid errors caused by individual differences in the human body.

Features:

A complete set of equipment used to measure the heat inside cars/trucks and the impact of air conditioning design on passenger comfort.

Sensors arranged in a matrix outside the human body can measure air velocity, temperature, radiant heat flow rate, 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 fingers is curved, grasping the steering wheel on the side of the car.

The flattened surface of the thighs (back and bottom) is similar to the shape of the human thighs being squeezed when sitting down.

Wireless electronic control transmission.

Main parameters:

Communication method: wireless wifi/wired

Dummy material: fiberglass

Air temperature measurement range: -20 ° C to+70 ° C

Calibration accuracy:+/-1.0 ° C

Configuration:

Lightweight epoxy carbon fiber shell.

Including a dummy body, sensor components, data collector, data processing unit, and data storage unit, the dummy body is equipped with joints in the shoulders, hips, knees, elbows, and ankles.

The arms of the shoulder joint can be moved in and out of the trunk, reflecting a wide range of driver postures.

The body can be divided into two parts on the waist, making it easy to fit into the testing vehicle.

Surface mounted sensors can measure air temperature, flow rate, radiant heat flow rate, and relative humidity.

The sensor protective cap can prevent damage to temperature and Confucius flow rate sensors during transportation and fixation.

The inability to retract and flatten the thighs in a finger like shape is designed to facilitate airflow movement.

The control components include wireless transmission through the IEEE802.11 network.

Connect the power and data cables to the side of the human model.

The transportation simulation program can display CAD model drawings.

Multiple human models can be connected to a data system.

Includes computer and control software.
