As shown in fig. 1 to 3, the apparatus for testing the comfort level of clothing according to the first embodiment of the present invention includes a controller 10, a dummy temperature control unit 20, a dummy temperature detection unit 30, and a dummy model 40, wherein the dummy temperature control unit 20 and the dummy temperature detection unit 30 are electrically connected to the controller 10, the dummy model 40 includes a liner 41, a constant temperature area 411 is formed in the liner 41, a fluid medium such as a gas medium or a liquid medium is filled in the constant temperature area 411, the dummy temperature detection unit 30 detects the temperature of the fluid medium, and the temperature information is transmitted to the controller 10, and the controller 10 controls the temperature of the constant temperature area 411 through the dummy temperature control unit 20.
The controller 10 may be a circuit module including a single-chip microcomputer or other processor, etc. for acquiring and analyzing data collected by the peripheral device. The inner liner 41 is typically a material with good thermal stability, such as metal, plastic, rubber, and supports the dummy.
In the present embodiment, the outer surface of the liner 41 may simulate the epidermis of a human body by filling the constant temperature area 411 with the fluid medium and controlling the temperature of the fluid medium by the dummy temperature detecting unit 30 and the dummy temperature controlling unit 20. When the comfort level of the clothing is evaluated, as the temperature of the outer surface of the lining is kept stable, after the dummy model 40 is sleeved with the clothing to be tested, the heat dissipation capacity of the dummy model 40 after the clothing to be tested is sleeved is calculated, and the thermal resistance of the clothing can be accurately obtained according to the area of the clothing to be tested, so that the heat preservation performance of the clothing is evaluated.
Preferably, the fluid medium may be a liquid medium to better maintain the temperature within liner 41 stable.
Further, the dummy 40 further includes an artificial skin 42 fitted over the inner liner 41, a gap 43 is formed between the artificial skin 42 and the inner liner 41, and the simulated sweat is stored in the gap 43.
Since the artificial skin 42 is sleeved outside the inner liner 41, and the gap 43 filled with the simulated sweat is formed between the artificial skin 42 and the inner liner 41. Thus, the artificial skin 42 may perform a sweat simulation, typically simulating natural evaporation of sweat, with the constant temperature area in motion increasing in temperature, simulating the evaporation of sweat by heating. After the garment to be tested is sleeved on the dummy model 40, the wet resistance and the thermal resistance of the garment to be tested and the surface layer (the air between the garment and the dummy) thereof can be calculated so as to evaluate the comfort of the garment.
In the evaluation, since the wet resistance and the thermal resistance of the artificial skin 42 are known at a constant temperature, the wet resistance and the thermal resistance of the test garment and the boundary layer thereof (formula 1) can be obtained by measuring the wet resistance and the thermal resistance which are expressed by fitting the test garment over the dummy model 40 and then subtracting the wet resistance and the thermal resistance of the artificial skin 42, respectively, to quantify the comfort of the garment. The calculation formula of the wet resistance and the thermal resistance is as follows:
wherein R e is the moisture resistance (Pa.m 2/W) of the garment and its attachment to the air;

E is the heat of vaporization (W.h/g) of water;
G e is the amount of evaporated perspiration (G/h) of the dummy;
H is the total heat dissipation capacity (W) of the dummy, and is usually calculated from the heating power of the heating device;
