What refrigeration does the air-conditioned vest rely on?

Air-conditioned vest, air-conditioned vest and refrigeration suit are two small fans installed at the left and right waist of a person's coat, which suck outdoor air into the clothes and absorb heat on the surface of the human body through vaporization heat that can evaporate sweat, thus cooling the human body. It is a cool and comfortable product. Product properties The human body has an ideal cooling system-physiological air conditioning. Due to the evaporation of sweat, the body surface temperature drops. After strenuous exercise, the human body can sweat more than 1000cc per hour. If all the sweat of 1000cc is evaporated, steaming can take away 580 kilocalories. This figure shows that the physiological air conditioning system has a strong refrigeration capacity, which is equivalent to taking away 480 kilocalories generated by continuous 1 hour heavy physical labor. At the same time, the amount of sweating is controlled by the brain, and the human body will sweat when necessary. However, there is a problem with human physiological air conditioning. The problem is that the human body itself can't make sweat evaporate, but the sweat stays on the body surface, so the body surface temperature of the human body can't drop sufficiently! What can solve this problem is air-conditioned clothes! Air-conditioned clothes can make a lot of external air flow parallel to the body surface, thus making sweat evaporate instantly. In this way, the human body can become a real physiological air conditioner. Under the normal operation of physiological air conditioner, sweat is in a state of continuous evaporation, no matter how much sweat, it can be guaranteed to be consistent with the amount needed by human body. The reason is that if the amount of perspiration is less than the amount needed by the human body, the body temperature will rise, and under the control of the brain, the amount of perspiration will increase, so that the insufficient part can be supplemented. On the contrary, if it exceeds the needs of the human body, the body temperature will drop and the amount of sweating will decrease. Therefore, if air-conditioned clothes are used, users can be in the most comfortable state. It is best to use high-grade polyester cloth and unique micro fan to make air-conditioning clothes. The principle is that through the air supply of the fan, sweat will evaporate immediately, absorb the heat on the surface of the human body, cool the human body and make people cool and comfortable. Air-conditioning clothing is a new type of high-temperature protective clothing product, which was authorized by the national invention patent in 2004. The use and maintenance of air-conditioned clothes are convenient, comfortable and cool with the special rechargeable lithium battery pack or adapter for power supply. Unique design, environmental protection and energy saving, comfortable and cool to wear. DC 3.2V-7.2V ultra-low voltage design, safe and reliable, will not cause any harm to human body. Humanized and considerate design, power supply, fan components, etc. Easy disassembly and cleaning, simple and safe operation. Other descriptions of outdoor workers (traffic police, forest protection police, border police, oilfield workers, railway workers, warehouse handling operations, places where air conditioning cannot be installed, high-temperature workplaces, etc.). ) It can not only quickly evaporate sweat, avoid the embarrassment of sweating and stinking, but also reduce skin problems caused by sweating, such as sweat rash, and more importantly.
