The composition and working principle of Thermal Manikin

The Thermal Manikin is a device that can be used to test the thermal comfort of garments. It consists of a manikin, a heat exchange system, a temperature, humidity and air velocity measurement system and a control system. The following section describes in detail the composition and working principle of the Thermal Manikin.

I. Composition

Human body model: The human body model is the main component of Thermal Manikin. It is a model that simulates the human form and can simulate the various thermal comfort states of the human body in an indoor environment.

Heat exchange system: The heat exchange system is used to simulate the heat exchange process of the human body in different indoor environments by controlling the flow of air through the manikin. The heat exchange system includes the skin of the manikin, internal temperature sensors, external insulation, air flow meters etc.

Temperature, humidity and air velocity measurement system: The temperature, humidity and air velocity measurement system is mainly used to measure the temperature, humidity and air velocity parameters in the thermal comfort test environment to determine whether the test conditions meet the standard requirements.

Control system: The control system is the core component of the Thermal Manikin and is used to control the heat exchange system, temperature, humidity and wind speed measurement systems to meet the test requirements.

II. Working principle

The Thermal Manikin works by controlling the heat exchange system of the manikin to simulate the heat exchange process of the human body in different indoor environments. Specifically, as the temperature and relative humidity of the gas flowing through the heat exchange system changes, so does the internal temperature and epidermal temperature of the manikin. The temperature, humidity and wind speed parameters are then measured by a temperature, humidity and wind speed measurement system to determine if the test conditions meet the standard requirements. Finally, the heat exchange system is controlled by the control system to meet the test requirements.

In summary, the Thermal Manikin is a special test device that can be used to simulate the thermal comfort of the human body in different indoor environments and is one of the most important devices for the scientific testing of the thermal comfort performance of clothing.
