Comfortable Thermal Manikin

The thermal manikin simulates real physiological heat exchange with the environment. By combining monitoring results with software analysis, it evaluates thermal comfort through protective clothing. It measures heat balance, analyzes environmental impact on comfort, and guides fabric/clothing development for special conditions. Using data-driven perception conclusions, it reduces errors from personal differences.

Application

Comfort-oriented thermal human body models have wide applications in various fields, including but not limited to:

Architectural Design: Used to assess the thermal comfort of building interiors and optimize the design of ventilation and air conditioning systems.

Automotive Engineering: Used to assess the thermal comfort of passenger compartments and optimize the design of vehicle air conditioning and ventilation systems.

HVAC System Design: Used to assess and optimize the thermal comfort of buildings and indoor environments, improving energy efficiency.

Environmental Control: Used to predict and control thermal comfort under asymmetric thermal environments, providing personalized thermal demand regulation solutions.

These applications demonstrate the importance of comfort-oriented thermal human body models in improving human comfort and optimizing environmental control.

Test Procedures

The operation method for comfort-type thermodynamic human models (such as dummies used for thermal comfort testing) covers experimental preparation, equipment connection, software settings, experimental execution, and post-experiment procedures. The following is a detailed description:

Experimental Preparation

Environmental Settings: Run the artificial climate chamber, set the required temperature and humidity conditions, and wait for the environment to stabilize. This is fundamental to ensuring the accuracy of the experimental results.

Dummy Preparation: Dress the dummy in the experimental sample (e.g., clothing) according to the experimental requirements. Ensure the dummy's joints are securely connected, especially if the experiment involves a walking system; check that the connecting rods for the walking system at the hands and feet are securely connected.

Water Bucket Preparation (if wet resistance or comfort testing is involved): Carry the white bucket to the deionized water room and fill it with water, ensuring the deionized water level is sufficient (more than 1/4 full).

Equipment Connection and Startup

Power Connection: Turn on the power strip and then start the DELL computer.

Data Cable Connection: Plug the gray data cable into the USB port of the DELL computer, ensuring smooth data transmission.

Equipment Switch: Turn on the power switch (usually located on the right side of the power supply box; I indicates the on position). If the experiment involves a water tank (such as for moisture resistance or comfort testing), the water tank switch must be turned on (usually located on the left side of the tank; "I" indicates the on state).

Software Setup and Startup

Software Startup: Open the ThermDac software (or other relevant software) on your computer desktop. Wait for the green COMM light on the software to illuminate, indicating normal operation.

Experiment Type Selection: Select the appropriate experiment type on the software toolbar according to the experimental requirements, such as thermal resistance test (SUDA-DRY TEST), moisture resistance test (SUDA-WET TEST), or comfort test.

Parameter Settings:

For moisture resistance and comfort tests, you may need to input the amount of sweat produced by various parts of the dummy or other relevant parameters.

For comfort tests, you may need to create a new tool, Model Control, and set the dummy's metabolic rate (ActLvl/MET) or walking speed (ActType), etc.

Experiment Execution

Start the Test: Click the "Start test" button in the lower right corner of the screen to begin the experiment. Save the file (it is recommended to create your own folder on the desktop so that you can copy the data after the experiment), and then click "Save". Data Recording: Wait for the experiment to end automatically (the message "Test completed" will appear), or collect data 30 minutes after the experimental conditions have stabilized according to standards. Manually end the experiment and save the data.

End Procedures:

Software Shutdown: First, close the ThermDac software (or other relevant software).

Equipment Shutdown: Turn off the computer, power supply box, and water tank switches (if applicable).

Power Shutdown: Finally, turn off the power strip and store the computer in a cabinet, locking it securely.

Follow-up Processing (e.g., for moisture resistance or comfort testing): After the experiment, a thermal resistance test may be necessary to dry the water inside the dummy to prevent damage to the equipment. Simultaneously, export and analyze the experimental data.
