The invention also discloses the method of heat dissipation dehumidification of the dummy device, featured by precise simulation, simple structure, convenient operation, wide application and low cost.

Description

Technical field [0001] The invention belongs to the research field of simulated human body devices, and specifically relates to a dummy device, a heat dissipation method and a moisture dissipation method for integrated simulation of human body heat dissipation and moisture dissipation. Background technique [0002] With the development of society and the advancement of science and technology, people have a new understanding and understanding of the relationship between people and the environment, and the foundation of the new understanding and understanding is the continuous breakthrough in people's research on the relationship between people and the environment. The relationship between people and the environment can cover all walks of life in society: the thermal comfort of clothing is the most direct factor that affects people’s perception of the surrounding environment, which is also an urgent problem in the textile industry; the interaction between people and the space capsul...

Problems solved by technology

The earliest dummy at home and abroad was successfully developed by Professor Goldman in the United States in the late 1960s. The dummy was coated with high moisture-absorbing cotton fabric to simulate sweating skin, and the sweat was sprayed onto the dummy through a sprayer. Coat cotton fabric, the operation process is quite cumbersome

In 1992, the VTT Research Center of Finland used rigid foam as the skeleton to develop the dummy model "Coppelius". The dummy has 187 sweat glands in the body, and the amount of sweating is controlled by a microcomputer and switching valves to simulate the sweating of the human body. Because the thermal resistance and moisture resistance of the clothing are determined according to the loss of water inside the dummy, the natural evaporation of water is ignored, the error is large, and the internal structure of the dummy is quite complicated.

In 2011, the dummy model "Newton" developed by the Northwest Testing Company of the United States uses an epoxy carbon fiber shell with a copper heating layer, a built-in heating device, a temperature sensor and an overall flow supply system, which can accurately simulate the heat dissipation of the human body. The test accuracy can reach ±0.1°C, but the cost of the dummy model is quite high, the price is about 800,000 US dollars per person, and the purchase cost of general scientific research centers or enterprises is too high
