DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the configuration of a clothing insulation analysis system according to the present invention will be described in detail with reference to the accompanying drawings.

First, the terminology used in the present invention will be explained. Clo (clo) is used to relax a person resting (radiating heat at 58 W / m ² ) at a temperature of 21 ° C and a wind velocity of 0.1 m / s 1 clo (claw) is 0.155 Km ² / W, as a unit of heat resistance (heat resistance value) required to make a sensation, or a unit of thermal resistance, which is roughly defined as the heat resistance value of a heavy menswear.

A clothing ensemble (referred to as 'apparel' for convenience) is a group of clothing that is worn together at the same time. Thermal insulation refers to the resistance to dry heat transfer through conduction, convection and radiation, or thermal resistance.

The following adiabatic values can be determined in the manner in which the present invention employs SI units.

R _a = thermal resistance of the air layer on the surface of the nude mannequin (heat insulation)

R _t = total heat resistance of the garment surrounding the mannequin and the surface air layer (heat insulation)

R _cl = average intrinsic heat resistance of clothing (heat insulation)

When measured values are expressed in claw units, the symbol I is used instead of R.

I _a = thermal resistance of the air layer on the surface of the nude mannequin (heat insulation)

I _t = total heat resistance of the garment surrounding the mannequin and the surface air layer (heat insulation)

I _cl = average intrinsic heat resistance of clothing (heat insulation)

All adiabatic values are measured directly on the manikin, and these values can be used to compare different dress suits, while each test is performed in the same experimental procedure and test conditions. The inherent garment insulation values are determined by subtracting the air layer resistance around the mannequin from the total insulation value of the corresponding garment suit.

This test method is applied to ascertain and compare the adequacy of the adiabatic appearances of different dressings, for example, the various designs and fabric structures used in the constructed clothes can be evaluated. The effect of clothes that are layered, surrounded, and properly entrapped can be measured as relating to apparel suits. Adiabatic values for apparel suits can be used in models that predict the physiological response of humans in different environmental conditions.

Prior to testing using the garment thermal insulation analysis system of the present invention, in the environmental test conditions, the air temperature is kept below the average temperature of the mannequins during the test (23 ° C). In particular, when a suit with high insulation values is tested (for example, in winter clothes), the air temperature should be low enough to maintain a minimum heat flux of 20 W / m ² from the parts of the mannequin.

The wind speed is maintained at 0.4 ± 0.1 m / s during the test and the relative humidity is selected between 30% and 70%, relative humidity ± 5%, preferably 50%. The average skin temperature of the mannequin is maintained at 35 ± 0.2 ° C during a 30 minute test.

(I.e., the average skin temperature and power input of the mannequin is maintained at plus or minus 3%) to the skinned mannequin with the selected skin temperature.

After the garment suit has reached equilibrium, the skin temperature and air temperature of the mannequin are recorded every minute and measured over 30 minutes.

The power of a heater (not shown) built into the mannequin to maintain a constant temperature is measured every minute, and this measurement continues during the test period.

Next, the calculation process in the clothing test and calculation processing unit 200 will be described in the present invention.

The clothing test is repeated three times independently.

Perform nudity test of the mannequin in order to compare it with the test result of the manikin that is caught. In this case, the test is performed under the same environmental conditions set in the clothing test to measure the thermal resistance (adiabatic value) ( R _a ) expressed by the air layer of the naked mannequin.

In calculating the total heat resistance (adiabatic value) in the calculation processing unit 200 in the present invention, the area weighted temperatures at all body parts are averaged by summing, before the total heat resistance of the clothes is calculated, And the sum of the areas are concurrently performed. That is, an average of the mannequin surface temperatures of all the body parts of the mannequin is averaged to determine the manikin surface temperature (T _s ), and the electric power (H) required to heat the mannequin by summing the electric power for heating each body part is obtained, Combine all areas of the mannequin to obtain the mannequin surface area (A). The temperature T _a of the air flowing over the garment may be the temperature in the chamber 107.

(Total heat resistance of clothes) ( R _t (total heat resistance)) of the clothing surrounding the mannequin and the surface air layer ) Is calculated using Equation (1).

Here, R _t = total heat resistance (adiabatic value) [° C · m ² / W]

A = manikin surface area [m ² ]

T _s = Manikin surface temperature [캜]

T _a = temperature of air flowing over clothing [° C]

H = power required to heat the mannequin [W].

The average total heat resistance (insulation value) ( R _t ) of the clothing (sample) is determined by averaging the values obtained from the three repeated tests.

If any of the total thermal resistance values of the three garments from the three replicate tests fluctuates by more than 10% from the average, the test is repeated if the result is out of the 10% limit. If a value is obtained from the test, the value is used instead, and if the retest is still outside the 10% limit, add 3 samples (apparel) and test.

R _t is multiplied by 6.45 to convert the average value R _t converted in SI units to I _t in clo.

The average intrinsic heat resistance (adiabatic value) R _cl of the garment is determined using the average value R _t (i.e., R _M ) and the equation (2).

R _M = average total heat resistance of the suit and the surface air layer (heat insulation value) [° C · m ² / W]

R _a = Thermal resistance of the air layer on the nude manikin surface [° C · m ² / W]

f _cl = Clothing area factor (no size).

The clothing area factor f _cl can be measured using the values in Table 1 or the standard ISO 9920. Clothing area factor f _cl may be a value stored in the setter according to the types of clothing in the storage section 240.

The average intrinsic heat resistance (R _cl ) of the garment is converted into SI units, and the average intrinsic thermal resistance (R _cl ) of the garment thus obtained is multiplied by 6.45 to convert it into _cl of clo.

Table 1 gives the area factors (f _cl ) of a typical protective garment.

When the series of calculations is completed, the calculation processing unit 200 determines the number and arrangement of the temperature sensors through the output unit 220 and the clothes used in the clothes suits input before the test through the key input unit 260 (Insulation value) (R _t or I _t ), the total inherent heat resistance (insulation value) of the garment suit, ( R _cl or I _cl ) , the thermal resistance (adiabatic value) ( R _a or I _a ) of the air bag around the nude mannequin, and the test environmental conditions are stored and stored in the storage unit 240.

At this time, you can test each of three garments one time and three times, or you can test three times with one garment suit. The signal detection also measures the skin temperature and air temperature of the mannequin every minute and measures over 30 minutes after the suit has reached equilibrium. The power of a heater (not shown) built into the mannequin to maintain a constant temperature is measured every minute, and this measurement continues during the test period.

In the manikin nudity test guidance step, the manikin nudity test is guided through the broadcast or display unit. In accordance with the nudity test guide, the user prepares the test using the manikin unit 105 (S150).

The mannequin nude body test is performed in accordance with the mannequin nude body test guide, and the test is performed under the same environmental conditions as in the third garment test.

That is, to compare with the test results of the manikin that has been subjected to the nakedness test of the manikin, the test is carried out under the same environmental conditions set in the clothing test.

(Thermal insulation value) R _a at the surface of the nude mannequin is obtained from the temperature signal of the nude mannequin received in the temperature signal reception step of the manikin nude body test in the air layer heat resistance calculation step of the nude mannequin (S170) .

The total thermal resistance ( R _t ) of the garment is obtained from each of the temperature signals of the three times of the clothes test received in the temperature signal receiving step of the clothes test No. 3, The clothing total heat resistance ( R _t ) is averaged to obtain the average clothing total thermal resistance (S 180).

In the counter increasing step, the counter is incremented by one (S190).

If the counter value is 1 (i.e., it is the first test) at the step of determining whether or not the test is the first test, the user is guided through three times of the clothing retest through the broadcasting or display unit. The user prepares a test such as wearing a piece of clothing on the part 105 (S220).

After three clothes re-examination guiding steps, three clothing re-tests are performed according to the clothing test guide. At this time, when the clothes are re-inspected three times, the temperature detected by the mannequin skin temperature measuring unit 110 The operation processing unit 200 receives the temperature signal (S230), and then returns to step S801 of calculating the average total heat resistance of the clothes (clothes). At this time, a retest is performed with the same clothing performed in the temperature signal receiving step (S140) of the third garment test.

If the counter value is not 1 (that is, if it is not the first test), it is determined whether the test is a retest or not (S240).

If the counter value is 2 (that is, if it is a retest) in the step of determining whether or not the re-test is to be performed, the additional apparel test by three additional apparel is guided through the broadcast or display unit, In accordance with the clothing test guide, the user prepares a test such as wearing a suit on the mannequin portion 105 (S250).

Three additional apparel test temperature signal receiving steps and three additional apparel test guiding steps followed by three additional apparel tests according to the apparel apparel test guideline, The arithmetic processing unit 200 receives the temperature signal detected by the temperature sensor 110 in step S260 and then returns to step S180 of calculating the average total thermal resistance of the clothes. At this time, the three additional apparel may be separate apparel not used in the first test or retest.

The average intrinsic heat resistance R _cl of the garment is obtained by calculating the intrinsic heat resistance of the garment, and the average intrinsic heat resistance R _cl of the garment is converted into the SI unit. by multiplying 6.45 to the mean specific thermal resistance (R _cl) and converts it into an average specific heat resistance (I _cl) of clo unit (S270).

In the output step, the average clothing thermal resistance and the specific heat resistance of the clothes are output to the output unit 220 (S280). Here, the output unit 220 outputs the number and arrangement of the temperature sensors, and the clothes (for example, a fiber material, a design shape, a weaving structure) used for the clothes suits inputted before the test through the key input unit 260 (R _t or I _t ), the total intrinsic thermal resistance (insulation value) of the garment suit ( R _cl or I _cl ) , the air around the naked mannequin The thermal resistance (adiabatic value) ( R _a or I _a ) of the _strand , and the test environmental conditions are output.
