According to the Chongqing Business Daily, as long as it is plugged in, even in the desert, it can extract water from the air to make water. Recently, Jin Guoyong, a junior at the University of Technology, invented such an "air water machine". 20 kg of water. Interestingly, the invention of the "air water machine" was inspired by the drought in Chongqing last year.
Drinkable after purifying air
On September 25, the reporter saw this “home multi-function refrigeration water storage and preservation device†in Jin Guoyong’s home. The outer casing of the machine is made of discarded cardboard boxes, less than half a meter high. At the bottom of the machine, a plastic pipe nearly one meter long is dragged. In less than half an hour, the water flowing out of the plastic pipe was filled with a small half basin. "I can use the water made by this machine to purify it, then I can drink it directly," said Jin Guoyong.
Said, Jin Guoyong opened the outer packaging of the machine made of paper shell, inside is a refrigeration compressor. In the refrigeration compressor, a copper tube with a diameter of only 1 cm, the air is sucked into the copper tube by the compressor, and then cooled to cool air. After the hot air outside the copper tube meets the cold air in the tube, it condenses into water droplets on the outer wall, and the water droplets are led out by the water guiding device. In addition, the cold air in the pipeline can also enter a specially designed fresh-keeping box through the pipeline, so that the food can be stored in the fresh-keeping box and function as a "refrigerator". The remaining cold air will not be wasted, it will be discharged directly into the room, so that one machine can achieve the three-in-one function of the water dispenser, refrigerator and even air conditioner.
The invention was inspired by the drought last year.
Jin Guoyong revealed that in the summer of Chongqing, the drought was short of water, and he was inspired. He thought of using the principle of "cold and hot air meet and condense into water" to make water. The manufacturing cost of the machine is only 600 yuan. As long as it is plugged in, it can produce 20 kilograms of water a day, and the power consumption is about 8 degrees. Even in the desert, as long as there is sufficient power, you can also effluent. At present, Jin Guoyong has applied to the Municipal Intellectual Property Office for a “new technology patentâ€, which is expected to be completed in December.
Amoy waste produces "air water machine"
In January of this year, Jin Guoyong began research and development. In order to raise money, he went to buy a station to dig some spare parts for home appliances. In addition, he sold half of the price of the computer he bought in his freshman year. Since most of the parts and instruments that were purchased were scrapped, the two machines that were first made failed, and the third set was successfully developed.
On September 25, a company in Zhejiang offered 50,000 yuan, hoping to buy out the patent right of this machine, but it was rejected by Jin Guoyong, and he hoped to start his own business.
After seeing this device, the experts of the Municipal Water Conservancy Bureau said that the machine is environmentally friendly for water resources, but the technology is still at a lower level and there is still a certain distance from the civilian use.
