A safety vest with coolant is attached to a cylindrical refrigerator by a tube. Switches on it, after 3 to 5 minutes, the vest begins to cool and the temperature is between 18 and 25 degrees. It is expected that it will be able to buy "air conditioning vest” on Taobao, micro shops and other platforms in September.
This "air conditioning vest” is based on space technology developed by China Aerospace Science and Engineering Institute, it can be used in protective equipment for individual cooling. The utility model is composed of a reflective hi vis vest with a cooling liquid, a cylindrical refrigerating unit and a power supply.
The refrigerating unit in the vest is a small refrigerator, when a person wearing a safety vest, the coolant in the vest absorbs heat from the body and then flows into the cooling unit to cool it, then enter into the vest, thus bringing cool feeling to the human body.
This "air conditioning vest" refrigeration unit weighs 4.6 kg equal to the weight of 4 bottles of mineral water, the vest with reflective tapes weighs 1 kg, the power weighs 1 kg. So It's easier to wear.
