(1) The cooling efficiency is low, and it is impossible to reach the comfortable temperature of the human body in a short time.

(2) The air-conditioning suit must have a good cooling effect in the case of a lot of sweating in the human body.

(3) If the temperature of the outdoor air is high, hot air blows over the surface of the human skin, and a good cooling effect cannot be achieved.

(4) The applicable object of the air-conditioning suit has limitations. The air-conditioning suit should be in direct contact with the human skin, otherwise it will not produce a good cooling effect. Therefore, the existing air-conditioning suits are mostly work clothes, however, this is not for the general public. Be applicable.

Between the two layers, in the present embodiment, the refrigerating passage is a passage formed by stitching a separate layer of the cloth body to the non-cotton layer of the inner layer cloth.

Example 3

As shown in FIGS. 3 and 4, the present embodiment is different from the first embodiment in that the refrigerating passage 7 is mainly composed of a main passage 22 and a plurality of branch passages 23 connected thereto, and is provided in the main passage 22 and the branch passage 23. The refrigeration line 9 is a hose, and in this embodiment, the refrigeration line 9 is fixed by the cooling passage 7. A through hole 10 is formed in the refrigeration line 9, and the through hole 10 can be opened according to the uniform distribution of the refrigerant. The diameter of the through hole 10 is the distance between each through hole 10 and the refrigerant container 3 from near to far. The direction is gradually increased.

The aperture of the through hole 10 is a small aperture, and at the distal end, since the flow velocity of the refrigerant is slowed down, the aperture of the through hole 10 is gradually increased for control implementation. Uniform delivery of refrigerant. The refrigerant flows out from the through hole 10 and penetrates through the inner layer cloth body to achieve the purpose of cooling the human body, so that the cooling amount is uniform and the human body feels comfortable.

The cold part of the human body refers to the special acupoints of the human body, the navel and the like which are susceptible to cold parts. An electromagnetic control valve is arranged on each branch line to accurately control the temperature of various parts of the body according to personal preference.

Example 4

As shown in FIGS. 5-7, the present embodiment differs from the third embodiment in that the refrigeration passage is a refrigeration circuit 14 of a hose, and a through hole 10 is formed in the refrigeration conduit 14, see FIG. The road 14 is fixed to the outer layer body 5 by means of a strip 27 or a buckle. Referring to Fig. 5, the aperture of the through hole 10 is gradually increased in a direction from the near to far by the distance between each of the through holes 10 and the refrigerant container 3. Referring to Fig. 7, the refrigerant container 3 is specifically fixed to the garment body 2 by means of a strap 28 attached thereto. The refrigeration line 14 is mainly composed of a main line 12 and a plurality of branch lines 13 connected thereto, and the main line 12 is connected to the refrigerant container 3, and the branch line 13 is distributed in a region corresponding to each part of the human body, in the branch line 13 is provided with a branch control valve, and the refrigerant is controlled to flow from the main line 12 into each branch line 13 through the total control valve 8 and the branch control valve, and the refrigerant absorbs heat and vaporizes, and passes through during the gasification process. The holes are volatilized to achieve rapid and even cooling of the human body.

The actual application of this embodiment is described as follows:

(1) Liquid nitrogen refrigeration duration:

According to the existing data, 1 cubic meter of liquid nitrogen is ‐196 degrees, gasified into 21.1 degrees of nitrogen, the volume is about 696.1 m ³ ; the density of liquid nitrogen is 0.81 g/cm ³ ; the volume of 1 kg of liquid nitrogen is ^{: 1000g / 0.81g / cm 3 =} 1234.5cm 3 is: 0.001234cm ^3; liquefied gas into a volume of 21.1 degrees ^{^{Celsius: 0.0012345 × 696.1m 3 = 0.86m 3}} . The inner diameter of the hose is approximately 2 to 2.5 mm (increasing or decreasing depending on the situation). Calculated according to the inner diameter of the hose of 2.5 mm, the cross-sectional area of the hose is 4.91 mm ² .

Since the specific gravity of nitrogen is almost the same as the specific gravity of air, the laying method of the hose of the present embodiment is advantageous for the diffusion of the refrigerant in the hose according to the characteristic that the cold air is easy to sink.

The calculation process is as follows:

Length of hose: 0.7×4+1×2=4.8m

The volume of the hose is: S × L = 4.91 mm ² × 4.8 m = 4.91 × 10 ^-4 × 4.8 m ³ = 2.36 × 10 ^-3 m ³

The number of times the liquid nitrogen after gasification can fill the hose is: 0.86m ³ /2.36×10 ^-3 m ³ =364 times

If the gas of 21.1 degrees in the hose can maintain the comfortable temperature of the human body (23-28 degrees) for about 5 minutes; then the duration of 1 kg of liquid nitrogen can maintain the comfortable temperature of the human body: 364 × 5 minutes = 1820 minutes, that is, 30.3 hours.

Conclusion: Considering that the gas in liquid nitrogen cannot be completely released in actual use, there will be some heat loss. Even with less than 50% efficiency, 1kg of liquid nitrogen can continue to maintain a comfortable body temperature of about 15 hours, which is about half a day.

If used for 5 hours per day, one can of 1 kg of liquid nitrogen can be used for at least three days. The recommended liquid nitrogen configuration is: 0.5kg to 5kg.

(2) Refrigeration area of air-conditioning suit:

The cooling area of the air-conditioning suit is about 2×0.4×0.7+2×1×0.1=0.76 square meters.

The total surface area of the human body: S = 0.0061 × height + 0.0124 × weight - 0.0099

Taking the height of the human body 170 cm and the weight of 70 kg as an example, the body surface area = 0.0061 × 170 + 0.124 × 70 = 1.905 square meters (including the body surface area of the head and neck, the hands and feet).

The 0.76 square meter refrigeration service area has covered 40% of the total human body area (including the head and neck and the palm of the hand). Therefore, the present invention can greatly improve the comfort of the human body.
