New warm body dummy tester
Product Description
In addition to heat dissipation to the surrounding environment through conduction, convection and radiation, the human body also loses heat through the evaporation of sweat on the surface of the human skin. If the water vapor can spread to the surrounding environment through the clothing system in time, the person will feel comfortable. If the clothing blocks the passage of the water vapor, the humidity in the microclimate between the human skin and the clothing will increase, the water vapor will accumulate to a certain extent and condense into water, making people feel uncomfortable. When the human body carries out strenuous activities or is in a hot environment, the evaporation of sweat becomes an important way for the human body to lose heat, and at this time, it is more necessary for clothes to have sufficient water vapor transmission capacity. Therefore, it is necessary to measure the evaporation resistance of clothing accurately in order to make a comprehensive evaluation of the heat and humidity transfer performance of clothing.
Meet the standard
ISO15831.GB/T 39605-2020
Scope of application
Building heat ventilation and air conditioning, aircraft, car comfort, all kinds of clothing thermal resistance test, wet clothing, sportswear research, cold and warm room on the human body impact analysis, high and low temperature environment, such as special fire experiment environment.
1. Building heat, ventilation and air conditioning.
2. Evaluation of aircraft and cars.
3. Thermal resistance test of all kinds of clothing.
4. Research on wet clothing and sportswear.
5. Analysis of the influence of heating and cooling rooms on the human body.
6. In high and low temperature environment, such as special fire test environment.
Main features
1. The whole body of the warm body dummy is divided into 35 anatomical sections such as head, trunk and limbs. Each section has adiabatic and fine tuning heater in each section.
2. In the control software part, the internal heat of the human body model, the temperature insulation performance of the clothing, the surface temperature evaluation of the human body model, the calculation of heat dissipation value, etc., can process various measurement data and record and statistical processing.
3. When making the human model of the warm body dummy, polymer functional materials with small heat capacity are used, which can quickly handle the heat reaction and heat exchange process of the human model.
4. Thermal nickel wire sensor, connected to the whole system, can measure the average temperature in each segment with good sensitivity.
5. Joints, shoulders and knees can be bent and changed into standing or sitting position, easy to disassemble clothes.
6. The warm body dummy system is equipped with the lifting frame of the human model, which can easily move the human model.
Product features
Thermal body model system (warm body sweating dummy) is used to evaluate the overall thermal and wet comfort of clothing, and provides accurate and effective test data for the study of mine thermal damage protection technology and the analysis and identification of metal and non-metal mine thermal damage accidents.
